test: parallelize test suite with pytest-xdist

~2min sequential runs were painful. Added pytest-xdist and -n auto
to run across all available cores. Tests already isolate state via
tmp_path fixtures so no changes needed to test code.

Local: 2677 passed in ~30s. CI gets 4 vCPUs on ubuntu-latest.

-Hermes-Agent is an agent harness for LLMs with an interactive CLI.
-
-## Development Environment
-
-**IMPORTANT**: Always use the virtual environment if it exists:
-```bash
-source venv/bin/activate  # Before running any Python commands
-```
-
-## Project Structure
-
-- `hermes` - CLI launcher script (run with `./hermes`)
-- `cli.py` - Interactive CLI with Rich UI, prompt_toolkit, animated spinners
-- `cli-config.yaml` - CLI configuration (model, terminal, toolsets, personalities)
-- `tools/` - Individual tool implementations (web, terminal, browser, vision, etc.)
-- `tools/__init__.py` - Exports all tools for importing
-- `model_tools.py` - Consolidates tool schemas and handlers for the agent
-- `toolsets.py` - Groups tools into logical toolsets (web, terminal, browser, etc.)
-- `toolset_distributions.py` - Probability-based tool selection for data generation
-- `run_agent.py` - Primary agent runner with AIAgent class and KawaiiSpinner
-- `batch_runner.py` - Parallel batch processing with checkpointing
-- `tests/` - Test scripts
-
-## File Dependency Chain
-
-```
-tools/*.py → tools/__init__.py → model_tools.py → toolsets.py → toolset_distributions.py
-                                       ↑
-run_agent.py ──────────────────────────┘
-cli.py → run_agent.py (uses AIAgent with quiet_mode=True)
-batch_runner.py → run_agent.py + toolset_distributions.py
-```
-
-Always ensure consistency between tools, model_tools.py, and toolsets.py when changing any of them.
-
-## CLI Architecture (cli.py)
-
-The interactive CLI uses:
-- **Rich** - For the welcome banner and styled panels
-- **prompt_toolkit** - For fixed input area with history and `patch_stdout`
-- **KawaiiSpinner** (in run_agent.py) - Animated feedback during API calls and tool execution
-
-Key components:
-- `HermesCLI` class - Main CLI controller with commands and conversation loop
-- `load_cli_config()` - Loads `cli-config.yaml`, sets environment variables for terminal
-- `build_welcome_banner()` - Displays ASCII art logo, tools, and skills summary
-- `/commands` - Process user commands like `/help`, `/clear`, `/personality`, etc.
-
-CLI uses `quiet_mode=True` when creating AIAgent to suppress verbose logging and enable kawaii-style feedback instead.
-
-### Adding CLI Commands
-
-1. Add to `COMMANDS` dict with description
-2. Add handler in `process_command()` method
-3. For persistent settings, use `save_config_value()` to update `cli-config.yaml`
-
-## Adding a New Tool
-
-Follow this strict order to maintain consistency:
-
-1. Create `tools/your_tool.py` with:
-   - Handler function (sync or async) returning a JSON string via `json.dumps()`
-   - `check_*_requirements()` function to verify dependencies (e.g., API keys)
-   - Schema definition following OpenAI function-calling format
-
-2. Export in `tools/__init__.py`:
-   - Import the handler and check function
-   - Add to `__all__` list
-
-3. Register in `model_tools.py`:
-   - Create `get_*_tool_definitions()` function or add to existing
-   - Add routing in `handle_function_call()` dispatcher
-   - Update `get_all_tool_names()` with the tool name
-   - Update `get_toolset_for_tool()` mapping
-   - Update `get_available_toolsets()` and `check_toolset_requirements()`
-
-4. Add to toolset in `toolsets.py`:
-   - Add to existing toolset or create new one in TOOLSETS dict
-
-5. Optionally add to `toolset_distributions.py` for batch processing
-
-## Tool Implementation Pattern
-
-```python
-# tools/example_tool.py
-import json
-import os
-
-def check_example_requirements() -> bool:
-    """Check if required API keys/dependencies are available."""
-    return bool(os.getenv("EXAMPLE_API_KEY"))
-
-def example_tool(param: str, task_id: str = None) -> str:
-    """Execute the tool and return JSON string result."""
-    try:
-        result = {"success": True, "data": "..."}
-        return json.dumps(result, ensure_ascii=False)
-    except Exception as e:
-        return json.dumps({"error": str(e)}, ensure_ascii=False)
-```
-
-All tool handlers MUST return a JSON string. Never return raw dicts.
-
-## Stateful Tools
-
-Tools that maintain state (terminal, browser) require:
-- `task_id` parameter for session isolation between concurrent tasks
-- `cleanup_*()` function to release resources
-- Cleanup is called automatically in run_agent.py after conversation completes
-
-## Environment Variables
-
-API keys are loaded from `.env` file in repo root:
-- `OPENROUTER_API_KEY` - Main LLM API access (primary provider)
-- `FIRECRAWL_API_KEY` - Web search/extract tools
-- `BROWSERBASE_API_KEY` / `BROWSERBASE_PROJECT_ID` - Browser automation
-- `FAL_KEY` - Image generation (FLUX model)
-- `NOUS_API_KEY` - Vision and Mixture-of-Agents tools
-
-Terminal tool configuration (can also be set in `cli-config.yaml`):
-- `TERMINAL_ENV` - Backend: local, docker, singularity, modal, or ssh
-- `TERMINAL_CWD` - Working directory
-- `TERMINAL_SSH_HOST`, `TERMINAL_SSH_USER`, `TERMINAL_SSH_KEY` - For SSH backend
-
-## Agent Loop (run_agent.py)
-
-The AIAgent class handles:
-- Processing enabled toolsets to provide to the model
-- Piping prompts to the agent
-- Looping LLM calls when tools are invoked, until natural language response
-- Returning the final response
-
-Uses OpenAI-compatible API (primarily OpenRouter) with the OpenAI Python SDK.
-
-## Reasoning Model Support
-
-For models that support chain-of-thought reasoning:
-- Extract `reasoning_content` from API responses
-- Store in `assistant_msg["reasoning"]` for trajectory export
-- Pass back via `reasoning_content` field on subsequent turns
-
-## Trajectory Format
-
-Conversations are saved in ShareGPT format for training:
-```json
-{"from": "system", "value": "System prompt with <tools>...</tools>"}
-{"from": "human", "value": "User message"}
-{"from": "gpt", "value": "<think>reasoning</think>\n<tool_call>{...}</tool_call>"}
-{"from": "tool", "value": "<tool_response>{...}</tool_response>"}
-{"from": "gpt", "value": "Final response"}
-```
-
-Tool calls use `<tool_call>` XML tags, responses use `<tool_response>` tags, reasoning uses `<think>` tags.
-
-## Batch Processing (batch_runner.py)
-
-For processing multiple prompts:
-- Parallel execution with multiprocessing
-- Content-based resume for fault tolerance (matches on prompt text, not indices)
-- Toolset distributions control probabilistic tool availability per prompt
-- Output: `data/<run_name>/trajectories.jsonl` (combined) + individual batch files
-
-## Logging
-
-Trajectories restructure tools as a system prompt for storage in a format suitable for later training use.
-
-## Skills System
-
-Skills are on-demand knowledge documents the agent can load. Located in `skills/` directory:
-
-```
-skills/
-├── mlops/                    # Category folder
-│   ├── axolotl/             # Skill folder
-│   │   ├── SKILL.md         # Main instructions (required)
-│   │   ├── references/      # Additional docs, API specs
-│   │   └── templates/       # Output formats, configs
-│   └── vllm/
-│       └── SKILL.md
-└── example-skill/
-    └── SKILL.md
-```
-
-**Progressive disclosure** (token-efficient):
-1. `skills_categories()` - List category names (~50 tokens)
-2. `skills_list(category)` - Name + description per skill (~3k tokens)
-3. `skill_view(name)` - Full content + tags + linked files
-
-SKILL.md files use YAML frontmatter:
-```yaml
----
-name: skill-name
-description: Brief description for listing
-tags: [tag1, tag2]
-related_skills: [other-skill]
-version: 1.0.0
----
-# Skill Content...
-```
-
-Tool files: `tools/skills_tool.py` → `model_tools.py` → `toolsets.py`

+        model: str = "anthropic/claude-opus-4.6",
+        max_iterations: int = 90,

+        session_id: str = None,
+        skip_context_files: bool = False,
+        skip_memory: bool = False,
+        # ... plus provider, api_mode, callbacks, routing params
+    ): ...
+
+    def chat(self, message: str) -> str:
+        """Simple interface — returns final response string."""
+
+    def run_conversation(self, user_message: str, system_message: str = None,
+                         conversation_history: list = None, task_id: str = None) -> dict:
+        """Full interface — returns dict with final_response + messages."""
+```
+
+### Agent Loop
+
+The core loop is inside `run_conversation()` — entirely synchronous:
+
+```python
+while api_call_count < self.max_iterations and self.iteration_budget.remaining > 0:
+    response = client.chat.completions.create(model=model, messages=messages, tools=tool_schemas)
+    if response.tool_calls:
+        for tool_call in response.tool_calls:
+            result = handle_function_call(tool_call.name, tool_call.args, task_id)
+            messages.append(tool_result_message(result))
+        api_call_count += 1
+    else:
+        return response.content
+```
+
+Messages follow OpenAI format: `{"role": "system/user/assistant/tool", ...}`. Reasoning content is stored in `assistant_msg["reasoning"]`.
+
+---
+
+## CLI Architecture (cli.py)
+
+- **Rich** for banner/panels, **prompt_toolkit** for input with autocomplete
+- **KawaiiSpinner** (`agent/display.py`) — animated faces during API calls, `┊` activity feed for tool results
+- `load_cli_config()` in cli.py merges hardcoded defaults + user config YAML
+- `process_command()` is a method on `HermesCLI` (not in commands.py)
+- Skill slash commands: `agent/skill_commands.py` scans `~/.hermes/skills/`, injects as **user message** (not system prompt) to preserve prompt caching
+
+### Adding CLI Commands
+
+1. Add to `COMMANDS` dict in `hermes_cli/commands.py`
+2. Add handler in `HermesCLI.process_command()` in `cli.py`
+3. For persistent settings, use `save_config_value()` in `cli.py`
+
+---
+
+## Adding New Tools
+
+Requires changes in **3 files**:
+
+**1. Create `tools/your_tool.py`:**
+```python
+import json, os
+from tools.registry import registry
+
+def check_requirements() -> bool:
+    return bool(os.getenv("EXAMPLE_API_KEY"))
+
+def example_tool(param: str, task_id: str = None) -> str:
+    return json.dumps({"success": True, "data": "..."})
+
+registry.register(
+    name="example_tool",
+    toolset="example",
+    schema={"name": "example_tool", "description": "...", "parameters": {...}},
+    handler=lambda args, **kw: example_tool(param=args.get("param", ""), task_id=kw.get("task_id")),
+    check_fn=check_requirements,
+    requires_env=["EXAMPLE_API_KEY"],
+)
+```
+
+**2. Add import** in `model_tools.py` `_discover_tools()` list.
+
+**3. Add to `toolsets.py`** — either `_HERMES_CORE_TOOLS` (all platforms) or a new toolset.
+
+The registry handles schema collection, dispatch, availability checking, and error wrapping. All handlers MUST return a JSON string.
+
+**Agent-level tools** (todo, memory): intercepted by `run_agent.py` before `handle_function_call()`. See `todo_tool.py` for the pattern.
+
+---
+
+## Adding Configuration
+
+### config.yaml options:
+1. Add to `DEFAULT_CONFIG` in `hermes_cli/config.py`
+2. Bump `_config_version` (currently 5) to trigger migration for existing users
+
+### .env variables:
+1. Add to `OPTIONAL_ENV_VARS` in `hermes_cli/config.py` with metadata:
+```python
+"NEW_API_KEY": {
+    "description": "What it's for",
+    "prompt": "Display name",
+    "url": "https://...",
+    "password": True,
+    "category": "tool",  # provider, tool, messaging, setting
+},
+```
+
+### Config loaders (two separate systems):
+
+| Loader | Used by | Location |
+|--------|---------|----------|
+| `load_cli_config()` | CLI mode | `cli.py` |
+| `load_config()` | `hermes tools`, `hermes setup` | `hermes_cli/config.py` |
+| Direct YAML load | Gateway | `gateway/run.py` |
+
+---
+
+## Important Policies
+
+### Prompt Caching Must Not Break
+
+Hermes-Agent ensures caching remains valid throughout a conversation. **Do NOT implement changes that would:**
+- Alter past context mid-conversation
+- Change toolsets mid-conversation
+- Reload memories or rebuild system prompts mid-conversation
+
+Cache-breaking forces dramatically higher costs. The ONLY time we alter context is during context compression.
+
+### Working Directory Behavior
+- **CLI**: Uses current directory (`.` → `os.getcwd()`)
+- **Messaging**: Uses `MESSAGING_CWD` env var (default: home directory)
+
+---
+
+## Known Pitfalls
+
+### DO NOT use `simple_term_menu` for interactive menus
+Rendering bugs in tmux/iTerm2 — ghosting on scroll. Use `curses` (stdlib) instead. See `hermes_cli/tools_config.py` for the pattern.
+
+### DO NOT use `\033[K` (ANSI erase-to-EOL) in spinner/display code
+Leaks as literal `?[K` text under `prompt_toolkit`'s `patch_stdout`. Use space-padding: `f"\r{line}{' ' * pad}"`.
+
+### `_last_resolved_tool_names` is a process-global in `model_tools.py`
+When subagents overwrite this global, `execute_code` calls after delegation may fail with missing tool imports. Known bug.
+
+### Tests must not write to `~/.hermes/`
+The `_isolate_hermes_home` autouse fixture in `tests/conftest.py` redirects `HERMES_HOME` to a temp dir. Never hardcode `~/.hermes/` paths in tests.
+
+---
+
+## Testing
+
+```bash
+source .venv/bin/activate
+python -m pytest tests/ -q          # Full suite (~2500 tests, ~2 min)
+python -m pytest tests/test_model_tools.py -q   # Toolset resolution
+python -m pytest tests/test_cli_init.py -q       # CLI config loading

+python -m pytest tests/tools/ -q                 # Tool-level tests

+# Contributing to Hermes Agent
+
+Thank you for contributing to Hermes Agent! This guide covers everything you need: setting up your dev environment, understanding the architecture, deciding what to build, and getting your PR merged.
+
+---
+
+## Contribution Priorities
+
+We value contributions in this order:
+
+1. **Bug fixes** — crashes, incorrect behavior, data loss. Always top priority.
+2. **Cross-platform compatibility** — Windows, macOS, different Linux distros, different terminal emulators. We want Hermes to work everywhere.

+
+---
+
+## Should it be a Skill or a Tool?
+
+This is the most common question for new contributors. The answer is almost always **skill**.
+
+### Make it a Skill when:
+
+- The capability can be expressed as instructions + shell commands + existing tools
+- It wraps an external CLI or API that the agent can call via `terminal` or `web_extract`
+- It doesn't need custom Python integration or API key management baked into the agent
+- Examples: arXiv search, git workflows, Docker management, PDF processing, email via CLI tools
+
+### Make it a Tool when:
+
+- It requires end-to-end integration with API keys, auth flows, or multi-component configuration managed by the agent harness
+- It needs custom processing logic that must execute precisely every time (not "best effort" from LLM interpretation)
+- It handles binary data, streaming, or real-time events that can't go through the terminal
+- Examples: browser automation (Browserbase session management), TTS (audio encoding + platform delivery), vision analysis (base64 image handling)
+
+### Should the Skill be bundled?
+
+Bundled skills (in `skills/`) ship with every Hermes install. They should be **broadly useful to most users**:
+
+- Document handling, web research, common dev workflows, system administration
+- Used regularly by a wide range of people
+
+If your skill is official and useful but not universally needed (e.g., a paid service integration, a heavyweight dependency), put it in **`optional-skills/`** — it ships with the repo but isn't activated by default. Users can discover it via `hermes skills browse` (labeled "official") and install it with `hermes skills install` (no third-party warning, builtin trust).
+
+If your skill is specialized, community-contributed, or niche, it's better suited for a **Skills Hub** — upload it to a skills registry and share it in the [Nous Research Discord](https://discord.gg/NousResearch). Users can install it with `hermes skills install`.

+## Architecture Overview
+
+### Core Loop
+
+```
+User message → AIAgent._run_agent_loop()
+  ├── Build system prompt (prompt_builder.py)
+  ├── Build API kwargs (model, messages, tools, reasoning config)
+  ├── Call LLM (OpenAI-compatible API)
+  ├── If tool_calls in response:
+  │     ├── Execute each tool via registry dispatch
+  │     ├── Add tool results to conversation
+  │     └── Loop back to LLM call
+  ├── If text response:
+  │     ├── Persist session to DB
+  │     └── Return final_response
+  └── Context compression if approaching token limit
+```
+
+### Key Design Patterns
+
+- **Self-registering tools**: Each tool file calls `registry.register()` at import time. `model_tools.py` triggers discovery by importing all tool modules.
+- **Toolset grouping**: Tools are grouped into toolsets (`web`, `terminal`, `file`, `browser`, etc.) that can be enabled/disabled per platform.
+- **Session persistence**: All conversations are stored in SQLite (`hermes_state.py`) with full-text search and unique session titles. JSON logs go to `~/.hermes/sessions/`.
+- **Ephemeral injection**: System prompts and prefill messages are injected at API call time, never persisted to the database or logs.
+- **Provider abstraction**: The agent works with any OpenAI-compatible API. Provider resolution happens at init time (Nous Portal OAuth, OpenRouter API key, or custom endpoint).
+- **Provider routing**: When using OpenRouter, `provider_routing` in config.yaml controls provider selection (sort by throughput/latency/price, allow/ignore specific providers, data retention policies). These are injected as `extra_body.provider` in API requests.
+
+---
+
+## Code Style
+
+- **PEP 8** with practical exceptions (we don't enforce strict line length)
+- **Comments**: Only when explaining non-obvious intent, trade-offs, or API quirks. Don't narrate what the code does — `# increment counter` adds nothing
+- **Error handling**: Catch specific exceptions. Log with `logger.warning()`/`logger.error()` — use `exc_info=True` for unexpected errors so stack traces appear in logs
+- **Cross-platform**: Never assume Unix. See [Cross-Platform Compatibility](#cross-platform-compatibility)
+
+---
+
+## Adding a New Tool
+
+Before writing a tool, ask: [should this be a skill instead?](#should-it-be-a-skill-or-a-tool)
+
+Tools self-register with the central registry. Each tool file co-locates its schema, handler, and registration:
+
+```python
+"""my_tool — Brief description of what this tool does."""
+
+import json
+from tools.registry import registry
+
+
+def my_tool(param1: str, param2: int = 10, **kwargs) -> str:
+    """Handler. Returns a string result (often JSON)."""
+    result = do_work(param1, param2)
+    return json.dumps(result)
+
+
+MY_TOOL_SCHEMA = {
+    "type": "function",
+    "function": {
+        "name": "my_tool",
+        "description": "What this tool does and when the agent should use it.",
+        "parameters": {
+            "type": "object",
+            "properties": {
+                "param1": {"type": "string", "description": "What param1 is"},
+                "param2": {"type": "integer", "description": "What param2 is", "default": 10},
+            },
+            "required": ["param1"],
+        },
+    },
+}
+
+
+def _check_requirements() -> bool:
+    """Return True if this tool's dependencies are available."""
+    return True
+
+
+registry.register(
+    name="my_tool",
+    toolset="my_toolset",
+    schema=MY_TOOL_SCHEMA,
+    handler=lambda args, **kw: my_tool(**args, **kw),
+    check_fn=_check_requirements,
+)
+```
+
+Then add the import to `model_tools.py` in the `_modules` list:
+
+```python
+_modules = [
+    # ... existing modules ...
+    "tools.my_tool",
+]
+```
+
+If it's a new toolset, add it to `toolsets.py` and to the relevant platform presets.
+
+---
+
+## Adding a Skill
+
+Bundled skills live in `skills/` organized by category. Official optional skills use the same structure in `optional-skills/`:
+
+```
+skills/
+├── research/
+│   └── arxiv/
+│       ├── SKILL.md              # Required: main instructions

+```
+
+### Platform-specific skills
+
+Skills can declare which OS platforms they support via the `platforms` frontmatter field. Skills with this field are automatically hidden from the system prompt, `skills_list()`, and slash commands on incompatible platforms.
+
+```yaml
+platforms: [macos]            # macOS only (e.g., iMessage, Apple Reminders)
+platforms: [macos, linux]     # macOS and Linux
+platforms: [windows]          # Windows only
+```
+
+If the field is omitted or empty, the skill loads on all platforms (backward compatible). See `skills/apple/` for examples of macOS-only skills.
+
+### Skill guidelines
+
+- **No external dependencies unless absolutely necessary.** Prefer stdlib Python, curl, and existing Hermes tools (`web_extract`, `terminal`, `read_file`).
+- **Progressive disclosure.** Put the most common workflow first. Edge cases and advanced usage go at the bottom.
+- **Include helper scripts** for XML/JSON parsing or complex logic — don't expect the LLM to write parsers inline every time.
+- **Test it.** Run `hermes --toolsets skills -q "Use the X skill to do Y"` and verify the agent follows the instructions correctly.
+
+---
+
+## Cross-Platform Compatibility
+
+Hermes runs on Linux, macOS, and Windows. When writing code that touches the OS:
+
+### Critical rules
+
+1. **`termios` and `fcntl` are Unix-only.** Always catch both `ImportError` and `NotImplementedError`:
+   ```python
+   try:
+       from simple_term_menu import TerminalMenu
+       menu = TerminalMenu(options)
+       idx = menu.show()
+   except (ImportError, NotImplementedError):
+       # Fallback: numbered menu for Windows
+       for i, opt in enumerate(options):
+           print(f"  {i+1}. {opt}")
+       idx = int(input("Choice: ")) - 1
+   ```
+
+2. **File encoding.** Windows may save `.env` files in `cp1252`. Always handle encoding errors:
+   ```python
+   try:
+       load_dotenv(env_path)
+   except UnicodeDecodeError:
+       load_dotenv(env_path, encoding="latin-1")
+   ```
+
+3. **Process management.** `os.setsid()`, `os.killpg()`, and signal handling differ on Windows. Use platform checks:
+   ```python
+   import platform
+   if platform.system() != "Windows":
+       kwargs["preexec_fn"] = os.setsid
+   ```
+
+4. **Path separators.** Use `pathlib.Path` instead of string concatenation with `/`.
+
+5. **Shell commands in installers.** If you change `scripts/install.sh`, check if the equivalent change is needed in `scripts/install.ps1`.
+
+---
+
+## Security Considerations
+
+Hermes has terminal access. Security matters.
+
+### Existing protections
+
+| Layer | Implementation |
+|-------|---------------|
+| **Sudo password piping** | Uses `shlex.quote()` to prevent shell injection |
+| **Dangerous command detection** | Regex patterns in `tools/approval.py` with user approval flow |
+| **Cron prompt injection** | Scanner in `tools/cronjob_tools.py` blocks instruction-override patterns |
+| **Write deny list** | Protected paths (`~/.ssh/authorized_keys`, `/etc/shadow`) resolved via `os.path.realpath()` to prevent symlink bypass |
+| **Skills guard** | Security scanner for hub-installed skills (`tools/skills_guard.py`) |
+| **Code execution sandbox** | `execute_code` child process runs with API keys stripped from environment |
+| **Container hardening** | Docker: all capabilities dropped, no privilege escalation, PID limits, size-limited tmpfs |
+
+### When contributing security-sensitive code
+
+- **Always use `shlex.quote()`** when interpolating user input into shell commands
+- **Resolve symlinks** with `os.path.realpath()` before path-based access control checks
+- **Don't log secrets.** API keys, tokens, and passwords should never appear in log output
+- **Catch broad exceptions** around tool execution so a single failure doesn't crash the agent loop
+- **Test on all platforms** if your change touches file paths, process management, or shell commands
+
+If your PR affects security, note it explicitly in the description.

-- **Interactive CLI**: Beautiful terminal interface with animated feedback, personalities, and session management
+**The self-improving AI agent built by [Nous Research](https://nousresearch.com).** It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.
-- **Web Tools**: Search, extract content, and crawl websites
-- **Terminal Tools**: Execute commands via local, Docker, Singularity, Modal, or SSH backends
-- **Browser Tools**: Automate web browsers to navigate, click, type, and extract content
-- **Vision Tools**: Analyze images from URLs
-- **Reasoning Tools**: Advanced multi-model reasoning (Mixture of Agents)
-- **Creative Tools**: Generate images from text prompts
-- **Skills Tools**: On-demand knowledge documents with progressive disclosure
-- **Toolsets System**: Organize tools into logical groups for different scenarios
-- **Batch Processing**: Process datasets in parallel with checkpointing and statistics tracking
-- **Ephemeral System Prompts**: Guide model behavior without polluting training datasets
 
-## Quick Start (CLI)
+Use any model you want — [Nous Portal](https://portal.nousresearch.com), [OpenRouter](https://openrouter.ai) (200+ models), [z.ai/GLM](https://z.ai), [Kimi/Moonshot](https://platform.moonshot.ai), [MiniMax](https://www.minimax.io), OpenAI, or your own endpoint. Switch with `hermes model` — no code changes, no lock-in.
 
-```bash
+<table>
-# After setup (see below), just run:
+<tr><td><b>A real terminal interface</b></td><td>Full TUI with multiline editing, slash-command autocomplete, conversation history, interrupt-and-redirect, and streaming tool output.</td></tr>
-./hermes
+<tr><td><b>Lives where you do</b></td><td>Telegram, Discord, Slack, WhatsApp, Signal, and CLI — all from a single gateway process. Voice memo transcription, cross-platform conversation continuity.</td></tr>
+<tr><td><b>A closed learning loop</b></td><td>Agent-curated memory with periodic nudges. Autonomous skill creation after complex tasks. Skills self-improve during use. FTS5 session search with LLM summarization for cross-session recall. <a href="https://github.com/plastic-labs/honcho">Honcho</a> dialectic user modeling. Compatible with the <a href="https://agentskills.io">agentskills.io</a> open standard.</td></tr>
+<tr><td><b>Scheduled automations</b></td><td>Built-in cron scheduler with delivery to any platform. Daily reports, nightly backups, weekly audits — all in natural language, running unattended.</td></tr>
+<tr><td><b>Delegates and parallelizes</b></td><td>Spawn isolated subagents for parallel workstreams. Write Python scripts that call tools via RPC, collapsing multi-step pipelines into zero-context-cost turns.</td></tr>
+<tr><td><b>Runs anywhere, not just your laptop</b></td><td>Six terminal backends — local, Docker, SSH, Daytona, Singularity, and Modal. Daytona and Modal offer serverless persistence — your agent's environment hibernates when idle and wakes on demand, costing nearly nothing between sessions. Run it on a $5 VPS or a GPU cluster.</td></tr>
+<tr><td><b>Research-ready</b></td><td>Batch trajectory generation, Atropos RL environments, trajectory compression for training the next generation of tool-calling models.</td></tr>
+</table>
 
-# Or with options:
-./hermes --model "anthropic/claude-sonnet-4" --toolsets "web,terminal"
-```
-
-The CLI provides:
-- Animated spinners during thinking and tool execution
-- Kawaii-style feedback messages
-- `/commands` for configuration, history, and session management
-- Customizable personalities (`/personality kawaii`, `/personality pirate`, etc.)
-- Persistent configuration via `cli-config.yaml`
-
-## Setup
-
-### 1. Clone the Repository
-```bash
-# Clone with submodules (recommended)
-git clone --recurse-submodules https://github.com/NousResearch/Hermes-Agent.git
-cd Hermes-Agent
-
-# Or if already cloned without submodules:
-git submodule update --init --recursive
-```
-
-### 2. Install Dependencies
-```bash
-# Create and activate virtual environment (recommended)
-python3 -m venv venv
-source venv/bin/activate  # On Windows: venv\Scripts\activate
-
-# Install Python packages
-pip install -r requirements.txt
-
-# Install mini-swe-agent for terminal tools
-pip install -e ./mini-swe-agent
-
-# Install Node.js dependencies for browser tools (requires Node.js)
-npm install
-```
-
-### 3. Configure Environment Variables
-```bash
-# Copy the example environment file
-cp .env.example .env
-
-# Edit .env and add your API keys
-nano .env  # or use your preferred editor
-```
-
-**Required API Keys:**
-- `OPENROUTER_API_KEY` - LLM access via OpenRouter (get at: https://openrouter.ai/keys)
-- `FIRECRAWL_API_KEY` - Web tools (get at: https://firecrawl.dev/)
-- `NOUS_API_KEY` - Vision & reasoning tools (get at: https://inference-api.nousresearch.com/)
-- `FAL_KEY` - Image generation (get at: https://fal.ai/)
-
-**Optional API Keys (for specific features):**
-- `BROWSERBASE_API_KEY` - Browser automation (get at: https://browserbase.com/)
-- `BROWSERBASE_PROJECT_ID` - From Browserbase dashboard
-- `MORPH_API_KEY` - For legacy Hecate terminal backend (get at: https://morph.so/)
-
-### 4. Configure Terminal Backend
-
-The terminal tool uses **mini-swe-agent** environments. Configure in `.env` or `cli-config.yaml`:
-
-```bash
-# Backend: "local", "docker", "singularity", "modal", or "ssh"
-TERMINAL_ENV=local          # Default: runs on host machine (no isolation)
-TERMINAL_ENV=ssh            # Remote execution via SSH (agent code stays local)
-TERMINAL_ENV=singularity    # Recommended for HPC: Apptainer/Singularity containers
-TERMINAL_ENV=docker         # Isolated Docker containers
-TERMINAL_ENV=modal          # Cloud execution via Modal
-
-# Container image (for docker/singularity/modal backends)
-TERMINAL_DOCKER_IMAGE=python:3.11-slim
-TERMINAL_SINGULARITY_IMAGE=docker://python:3.11-slim
-TERMINAL_TIMEOUT=60
-
-# SSH backend (for ssh)
-TERMINAL_SSH_HOST=my-server.example.com
-TERMINAL_SSH_USER=myuser
-TERMINAL_SSH_KEY=~/.ssh/id_rsa  # Optional, uses ssh-agent if not set
-```
-
-**Backend Requirements:**
-- **local**: No extra setup (runs directly on your machine, no isolation)
-- **ssh**: SSH access to remote machine (great for sandboxing - agent can't touch its own code)
-- **singularity**: Requires Apptainer or Singularity installed (common on HPC clusters, no root needed)
-- **docker**: Requires Docker installed and user in `docker` group
-- **modal**: Requires Modal account (see setup below)
-
-### Singularity/Apptainer Setup (Recommended for HPC)
-
-Singularity/Apptainer provides rootless container execution, ideal for HPC clusters:
-
-```bash
-# 1. Verify Apptainer is installed
-apptainer --version  # or: singularity --version
-
-# 2. Set up cache directories (important for parallel workers)
-# Use /scratch if available (HPC), otherwise /tmp
-export APPTAINER_CACHEDIR=/scratch/$USER/.apptainer
-export APPTAINER_TMPDIR=/scratch/$USER/.apptainer/tmp
-mkdir -p "$APPTAINER_CACHEDIR" "$APPTAINER_TMPDIR"
-
-# 3. Pre-build SIF image (recommended for parallel batch processing)
-# This avoids race conditions when multiple workers start simultaneously
-apptainer build $APPTAINER_CACHEDIR/python-nodejs.sif docker://nikolaik/python-nodejs:python3.11-nodejs20
-
-# 4. Configure .env to use the local SIF
-TERMINAL_ENV=singularity
-TERMINAL_SINGULARITY_IMAGE=/scratch/$USER/.apptainer/python-nodejs.sif
-```
-
-**Tip:** The batch scripts in `configs/` automatically handle SIF pre-building if `/scratch` is available.
-
-### Modal Cloud Backend Setup
-
-[Modal](https://modal.com) provides serverless cloud compute for running sandboxed environments at scale.
-
-```bash
-# 1. Install Modal and dependencies
-pip install modal boto3
-
-# 2. Authenticate with Modal (opens browser)
-modal setup
-
-# 3. Set terminal backend to modal in .env
-TERMINAL_ENV=modal
-```
-
-Modal uses CLI-based authentication (stored in `~/.modal/`), so no API key is needed in `.env`. After running `modal setup`, commands will automatically execute in Modal's cloud sandboxes.
-
-### Browser Tools Setup
-
-Browser tools enable the agent to navigate websites, fill forms, click buttons, and extract content. They use [agent-browser](https://github.com/vercel-labs/agent-browser) CLI with [Browserbase](https://browserbase.com) cloud execution.
-
-```bash
-# 1. Install Node.js (if not already installed)
-# Use nvm (recommended) or your package manager
-
-# 2. Install agent-browser CLI (choose one option):
-npm install -g agent-browser     # Option A: Global install (recommended)
-npm install                      # Option B: Local install (uses npx fallback)
-
-# 3. Get Browserbase credentials
-# Sign up at https://browserbase.com/ and get your:
-# - API Key (from Settings → API Keys)
-# - Project ID (from your project dashboard)
-
-# 4. Add to your .env file:
-BROWSERBASE_API_KEY=your_api_key_here
-BROWSERBASE_PROJECT_ID=your_project_id_here
-```
-
-**Available Browser Tools:**
-
-| Tool | Description |
-|------|-------------|
-| `browser_navigate` | Navigate to a URL |
-| `browser_snapshot` | Get text-based page snapshot with element refs |

-  --query "Go to amazon.com and find the price of the latest Kindle" \
-  --enabled_toolsets=browser,web,vision
-
-# Use browser-focused distribution
-python batch_runner.py \
-  --dataset_file=browser_tasks.jsonl \
-  --distribution=browser_use \
-  --run_name=browser_run
-```
-
-See `.env.example` for all available configuration options including debug settings.
-
-### Skills Tools
-
-Skills are on-demand knowledge documents the agent can load when needed. They follow a **progressive disclosure** pattern to minimize token usage:
-
-```
-skills/
-├── mlops/                    # Category folder
-│   ├── axolotl/             # Skill folder
-│   │   ├── SKILL.md         # Main instructions (required)
-│   │   ├── references/      # Additional docs, API specs
-│   │   └── templates/       # Output formats, configs
-│   └── vllm/
-│       └── SKILL.md
-```
-
-**Available Skills Tools:**
-
-| Tool | Description |
-|------|-------------|
-| `skills_categories` | List available skill categories (~50 tokens) |
-| `skills_list` | List skills with name + description (~3k tokens for 40 skills) |
-| `skill_view` | Load full skill content, tags, and linked files |
-
-**Example Usage:**
-```bash
-# Use skills tools
-python run_agent.py \
-  --query "What skills do you have for fine-tuning? Show me the axolotl skill." \
-  --enabled_toolsets=skills
-```
-
-**Creating Skills:**
-
-Skills use YAML frontmatter for metadata:
-```yaml
 ---
-name: my-skill
+
-description: Brief description shown in skills_list
+## Quick Install
-tags: [tag1, tag2]
+
-related_skills: [other-skill]
+```bash
-version: 1.0.0
+curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
+```
+
+Works on Linux, macOS, and WSL2. The installer handles everything — Python, Node.js, dependencies, and the `hermes` command. No prerequisites except git.
+
+> **Windows:** Native Windows is not supported. Please install [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install) and run the command above.
+
+After installation:
+
+```bash
+source ~/.bashrc    # reload shell (or: source ~/.zshrc)
+hermes setup        # configure your LLM provider
+hermes              # start chatting!
+```
+
 ---
-# Skill Content
 
-Instructions, examples, and guidelines here...
+## Getting Started
-```
-
-Skills can include:
-- `references/` - Additional documentation, API specs, examples
-- `templates/` - Output formats, config files, boilerplate code
-- `scripts/` - Executable helpers (Python, shell scripts)
-
-## Session Logging
-
-Every conversation is automatically logged to `logs/` for debugging and inspection:
-
-```
-logs/
-├── session_20260201_143052_a1b2c3.json
-├── session_20260201_150217_d4e5f6.json
-└── ...
-```
-
-**Log Format:**
-```json
-{
-  "session_id": "20260201_143052_a1b2c3",
-  "model": "anthropic/claude-sonnet-4",
-  "session_start": "2026-02-01T14:30:52.123456",
-  "last_updated": "2026-02-01T14:35:12.789012",
-  "message_count": 8,
-  "conversations": [
-    {"from": "system", "value": "..."},
-    {"from": "human", "value": "..."},
-    {"from": "gpt", "value": "..."},
-    {"from": "tool", "value": "..."}
-  ]
-}
-```
-
-- **Automatic**: Logs are created and updated automatically after each conversation turn
-- **Session ID in Banner**: The CLI displays the session ID in the welcome banner
-- **Trajectory Format**: Uses the same format as batch processing for consistency
-- **Git Ignored**: `logs/` is in `.gitignore` so logs aren't committed
-

-# Custom personalities (use with /personality command)
+Quick start for contributors:
-agent:
-  personalities:
-    helpful: "You are a helpful assistant."
-    kawaii: "You are a kawaii assistant! Use cute expressions..."
-```
-
-### Personalities
-
-Built-in personalities available via `/personality`:
-- `helpful`, `concise`, `technical`, `creative`, `teacher`
-- `kawaii`, `catgirl`, `pirate`, `shakespeare`, `surfer`
-- `noir`, `uwu`, `philosopher`, `hype`
-
-## Toolsets System
-
-The agent uses a toolsets system for organizing and managing tools. All tools must be part of a toolset to be accessible - individual tool selection is not supported. This ensures consistent and logical grouping of capabilities.
-
-### Key Concepts
-
-- **Toolsets**: Logical groups of tools for specific use cases (e.g., "research", "development", "debugging")
-- **Composition**: Toolsets can include other toolsets for powerful combinations
-- **Custom Toolsets**: Create your own toolsets at runtime or by editing `toolsets.py`
-- **Toolset-Only Access**: Tools are only accessible through toolsets, not individually
-
-### Available Toolsets
-
-See `toolsets.py` for the complete list of predefined toolsets including:
-- Basic toolsets (web, terminal, vision, creative, reasoning)
-- Composite toolsets (research, development, analysis, etc.)
-- Scenario-specific toolsets (debugging, documentation, API testing, etc.)
-- Special toolsets (safe mode without terminal, minimal, offline)
-
-### Using Toolsets
 
 ```bash
-# Use a predefined toolset
+git clone --recurse-submodules https://github.com/NousResearch/hermes-agent.git
-python run_agent.py --enabled_toolsets=research --query "Find latest AI papers"
+cd hermes-agent
-
+curl -LsSf https://astral.sh/uv/install.sh | sh
-# Combine multiple toolsets
+uv venv .venv --python 3.11
-python run_agent.py --enabled_toolsets=web,vision --query "Analyze this website"
+source .venv/bin/activate
-
+uv pip install -e ".[all,dev]"
-# Enable all toolsets explicitly (same as omitting the flag)
+uv pip install -e "./mini-swe-agent"
-python run_agent.py --enabled_toolsets=all --query "Do web research and run commands if helpful"
+python -m pytest tests/ -q
-
-# Safe mode (no terminal access)
-python run_agent.py --enabled_toolsets=safe --query "Help without running commands"
-
-# List all available toolsets and tools
-python run_agent.py --list_tools
 ```
 
-See `toolsets.py` for the complete list of available toolsets and how to create custom ones.

-
-## Batch Processing
-
-Process multiple prompts from a dataset in parallel with automatic checkpointing and statistics tracking:
-
-```bash
-# Basic batch processing
-python batch_runner.py \
-  --dataset_file=prompts.jsonl \
-  --batch_size=20 \
-  --run_name=my_run
-
-# With specific distribution
-python batch_runner.py \
-  --dataset_file=prompts.jsonl \
-  --batch_size=20 \
-  --run_name=image_run \
-  --distribution=image_gen \
-  --num_workers=4
-```
-
-**Key Features:**
-- Parallel processing with configurable workers
-- Toolset distributions for varied data generation
-- Automatic checkpointing and resume capability
-- Combined output in `data/<run_name>/trajectories.jsonl`
-- Tool usage statistics and success rates
-
-Use `--list_distributions` to see available toolset distributions for varied data generation.
-
-### Trajectory Compression
-
-Post-process trajectories to fit within token budgets for training:
-
-```bash
-# Compress a directory of JSONL files
-python trajectory_compressor.py --input=data/my_run
-
-# Compress a single JSONL file
-python trajectory_compressor.py --input=data/trajectories.jsonl
-
-# Compress a 15% sample (useful for creating smaller training sets)
-python trajectory_compressor.py --input=data/trajectories.jsonl --sample_percent=15
-
-# Custom output and token target
-python trajectory_compressor.py \
-  --input=data/trajectories.jsonl \
-  --output=data/compressed.jsonl \
-  --target_max_tokens=16000
-```
-
-**Features:**
-- Protects first turns (system, human, first GPT response, first tool call)
-- Protects last N turns (configurable)
-- Summarizes middle turns using LLM to fit target token budget
-- Supports both directory and single file input
-- Optional random sampling with `--sample_percent`
-- Configurable via `configs/trajectory_compression.yaml`
-
-### Ephemeral System Prompts
-
-The ephemeral system prompt feature allows you to guide the model's behavior during batch processing **without** saving that prompt to the training dataset trajectories. This is useful for:
-
-- Guiding model behavior during data collection
-- Adding task-specific instructions 
-- Keeping saved trajectories clean and focused on tool-calling format
-
-**Example:**
-```bash
-python batch_runner.py \
-  --dataset_file=prompts.jsonl \
-  --batch_size=10 \
-  --run_name=my_run \
-  --ephemeral_system_prompt="You are a helpful assistant focused on image generation."
-```
-
-The ephemeral prompt will influence the model's behavior during execution, but **only the standard tool-calling system prompt** will be saved in the trajectory files.
-
-The ephemeral prompt influences model behavior during execution, but **only the standard tool-calling system prompt** is saved in trajectory files.

-# Hermes Agent - Future Improvements
-
-> Ideas for enhancing the agent's capabilities, generated from self-analysis of the codebase.
-
----
-
-## 🚨 HIGH PRIORITY - Immediate Fixes
-
-These items need to be addressed ASAP:
-
-### 1. SUDO Breaking Terminal Tool 🔐 ✅ COMPLETE
-- [x] **Problem:** SUDO commands break the terminal tool execution (hangs indefinitely)
-- [x] **Fix:** Created custom environment wrappers in `tools/terminal_tool.py`
-  - `stdin=subprocess.DEVNULL` prevents hanging on interactive prompts
-  - Sudo fails gracefully with clear error if no password configured
-  - Same UX as Claude Code - agent sees error, tells user to run it themselves
-- [x] **All 5 environments now have consistent behavior:**
-  - `_LocalEnvironment` - local execution
-  - `_DockerEnvironment` - Docker containers
-  - `_SingularityEnvironment` - Singularity/Apptainer containers
-  - `_ModalEnvironment` - Modal cloud sandboxes
-  - `_SSHEnvironment` - remote SSH execution
-- [x] **Optional sudo support via `SUDO_PASSWORD` env var:**
-  - Shared `_transform_sudo_command()` helper used by all environments
-  - If set, auto-transforms `sudo cmd` → pipes password via `sudo -S`
-  - Documented in `.env.example`, `cli-config.yaml`, and README
-  - Works for chained commands: `cmd1 && sudo cmd2`
-- [x] **Interactive sudo prompt in CLI mode:**
-  - When sudo detected and no password configured, prompts user
-  - 45-second timeout (auto-skips if no input)
-  - Hidden password input via `getpass` (password not visible)
-  - Password cached for session (don't ask repeatedly)
-  - Spinner pauses during prompt for clean UX
-  - Uses `HERMES_INTERACTIVE` env var to detect CLI mode
-
-### 2. Fix `browser_get_images` Tool 🖼️ ✅ VERIFIED WORKING
-- [x] **Tested:** Tool works correctly on multiple sites
-- [x] **Results:** Successfully extracts image URLs, alt text, dimensions
-- [x] **Note:** Some sites (Pixabay, etc.) have Cloudflare bot protection that blocks headless browsers - this is expected behavior, not a bug
-
-### 3. Better Action Logging for Debugging 📝 ✅ COMPLETE
-- [x] **Problem:** Need better logging of agent actions for debugging
-- [x] **Implementation:**
-  - Save full session trajectories to `logs/` directory as JSON
-  - Each session gets a unique file: `session_YYYYMMDD_HHMMSS_UUID.json`
-  - Logs all messages, tool calls with inputs/outputs, timestamps
-  - Structured JSON format for easy parsing and replay
-  - Automatic on CLI runs (configurable)
-
-### 4. Stream Thinking Summaries in Real-Time 💭 ⏸️ DEFERRED
-- [ ] **Problem:** Thinking/reasoning summaries not shown while streaming
-- [ ] **Complexity:** This is a significant refactor - leaving for later
-
-**OpenRouter Streaming Info:**
-- Uses `stream=True` with OpenAI SDK
-- Reasoning comes in `choices[].delta.reasoning_details` chunks
-- Types: `reasoning.summary`, `reasoning.text`, `reasoning.encrypted`
-- Tool call arguments stream as partial JSON (need accumulation)
-- Items paradigm: same ID emitted multiple times with updated content
-
-**Key Challenges:**
-- Tool call JSON accumulation (partial `{"query": "wea` → `{"query": "weather"}`)
-- Multiple concurrent outputs (thinking + tool calls + text simultaneously)
-- State management for partial responses
-- Error handling if connection drops mid-stream
-- Deciding when tool calls are "complete" enough to execute
-
-**UX Questions to Resolve:**
-- Show raw thinking text or summarized?
-- Live expanding text vs. spinner replacement?
-- Markdown rendering while streaming?
-- How to handle thinking + tool call display simultaneously?
-
-**Implementation Options:**
-- New `run_conversation_streaming()` method (keep non-streaming as fallback)
-- Wrapper that handles streaming internally
-- Big refactor of existing `run_conversation()`
-

-## 1. Subagent Architecture (Context Isolation) 🎯
-
-**Problem:** Long-running tools (terminal commands, browser automation, complex file operations) consume massive context. A single `ls -la` can add hundreds of lines. Browser snapshots, debugging sessions, and iterative terminal work quickly bloat the main conversation, leaving less room for actual reasoning.
-
-**Solution:** The main agent becomes an **orchestrator** that delegates context-heavy tasks to **subagents**.
-
-**Architecture:**
-```
-┌─────────────────────────────────────────────────────────────────┐
-│  ORCHESTRATOR (main agent)                                      │
-│  - Receives user request                                        │
-│  - Plans approach                                               │
-│  - Delegates heavy tasks to subagents                           │
-│  - Receives summarized results                                  │
-│  - Maintains clean, focused context                             │
-└─────────────────────────────────────────────────────────────────┘
-         │                    │                    │
-         ▼                    ▼                    ▼
-┌─────────────────┐  ┌─────────────────┐  ┌─────────────────┐

-│ Returns summary │  │ Returns summary │  │ Returns summary │
-└─────────────────┘  └─────────────────┘  └─────────────────┘
-```
-
-**How it works:**
-1. User asks: "Set up a new Python project with FastAPI and tests"
-2. Orchestrator plans: "I need to create files, install deps, write code"
-3. Orchestrator calls: `terminal_task(goal="Create venv, install fastapi pytest", context="New project in ~/myapp")`
-4. **Subagent spawns** with fresh context, only terminal/file tools
-5. Subagent iterates (may take 10+ tool calls, lots of output)
-6. Subagent completes → returns summary: "Created venv, installed fastapi==0.109.0, pytest==8.0.0"
-7. Orchestrator receives **only the summary**, context stays clean
-8. Orchestrator continues with next subtask
-
-**Key tools to implement:**
-- [ ] `terminal_task(goal, context, cwd?)` - Delegate terminal/shell work
-- [ ] `browser_task(goal, context, start_url?)` - Delegate web research/automation  
-- [ ] `code_task(goal, context, files?)` - Delegate code writing/modification
-- [ ] Generic `delegate_task(goal, context, toolsets=[])` - Flexible delegation
-
-**Implementation details:**
-- [ ] Subagent uses same `run_agent.py` but with:
-  - Fresh/empty conversation history
-  - Limited toolset (only what's needed)
-  - Smaller max_iterations (focused task)
-  - Task-specific system prompt
-- [ ] Subagent returns structured result:
-  ```python
-  {
-    "success": True,
-    "summary": "Installed 3 packages, created 2 files",
-    "details": "Optional longer explanation if needed",
-    "artifacts": ["~/myapp/requirements.txt", "~/myapp/main.py"],  # Files created
-    "errors": []  # Any issues encountered
-  }
-  ```
-- [ ] Orchestrator sees only the summary in its context
-- [ ] Full subagent transcript saved separately for debugging
-
-**Benefits:**
-- 🧹 **Clean context** - Orchestrator stays focused, doesn't drown in tool output
-- 📊 **Better token efficiency** - 50 terminal outputs → 1 summary paragraph
-- 🎯 **Focused subagents** - Each agent has just the tools it needs
-- 🔄 **Parallel potential** - Independent subtasks could run concurrently
-- 🐛 **Easier debugging** - Each subtask has its own isolated transcript
-
-**When to use subagents vs direct tools:**
-- **Subagent**: Multi-step tasks, iteration likely, lots of output expected
-- **Direct**: Quick one-off commands, simple file reads, user needs to see output
-
-**Files to modify:** `run_agent.py` (add orchestration mode), new `tools/delegate_tools.py`, new `subagent_runner.py`
-
----
-
-## 2. Context Management (complements Subagents)
-
-**Problem:** Context grows unbounded during long conversations. Trajectory compression exists for training data post-hoc, but live conversations lack intelligent context management.
-
-**Ideas:**
-- [ ] **Incremental summarization** - Compress old tool outputs on-the-fly during conversations
-  - Trigger when context exceeds threshold (e.g., 80% of max tokens)
-  - Preserve recent turns fully, summarize older tool responses
-  - Could reuse logic from `trajectory_compressor.py`
-  
-- [ ] **Semantic memory retrieval** - Vector store for long conversation recall
-  - Embed important facts/findings as conversation progresses
-  - Retrieve relevant memories when needed instead of keeping everything in context
-  - Consider lightweight solutions: ChromaDB, FAISS, or even a simple embedding cache
-  
-- [ ] **Working vs. episodic memory** distinction
-  - Working memory: Current task state, recent tool results (always in context)
-  - Episodic memory: Past findings, tried approaches (retrieved on demand)
-  - Clear eviction policies for each
-
-**Files to modify:** `run_agent.py` (add memory manager), possibly new `tools/memory_tool.py`
-
----
-
-## 3. Self-Reflection & Course Correction 🔄
-
-**Problem:** Current retry logic handles malformed outputs but not semantic failures. Agent doesn't reason about *why* something failed.
-
-**Ideas:**
-- [ ] **Meta-reasoning after failures** - When a tool returns an error or unexpected result:
-  ```
-  Tool failed → Reflect: "Why did this fail? What assumptions were wrong?"
-  → Adjust approach → Retry with new strategy
-  ```
-  - Could be a lightweight LLM call or structured self-prompt
-  
-- [ ] **Planning/replanning module** - For complex multi-step tasks:
-  - Generate plan before execution
-  - After each step, evaluate: "Am I on track? Should I revise the plan?"
-  - Store plan in working memory, update as needed
-  
-- [ ] **Approach memory** - Remember what didn't work:
-  - "I tried X for this type of problem and it failed because Y"
-  - Prevents repeating failed strategies in the same conversation
-
-**Files to modify:** `run_agent.py` (add reflection hooks in tool loop), new `tools/reflection_tool.py`
-
----
-
-## 4. Tool Composition & Learning 🔧
-
-**Problem:** Tools are atomic. Complex tasks require repeated manual orchestration of the same tool sequences.
-
-**Ideas:**
-- [ ] **Macro tools / Tool chains** - Define reusable tool sequences:
-  ```yaml
-  research_topic:
-    description: "Deep research on a topic"
-    steps:
-      - web_search: {query: "$topic"}
-      - web_extract: {urls: "$search_results.urls[:3]"}
-      - summarize: {content: "$extracted"}
-  ```
-  - Could be defined in skills or a new `macros/` directory
-  - Agent can invoke macro as single tool call
-  
-- [ ] **Tool failure patterns** - Learn from failures:
-  - Track: tool, input pattern, error type, what worked instead
-  - Before calling a tool, check: "Has this pattern failed before?"
-  - Persistent across sessions (stored in skills or separate DB)
-  
-- [ ] **Parallel tool execution** - When tools are independent, run concurrently:
-  - Detect independence (no data dependencies between calls)
-  - Use `asyncio.gather()` for parallel execution
-  - Already have async support in some tools, just need orchestration
-
-**Files to modify:** `model_tools.py`, `toolsets.py`, new `tool_macros.py`
-
----
-
-## 5. Dynamic Skills Expansion 📚
-
-**Problem:** Skills system is elegant but static. Skills must be manually created and added.
-
-**Ideas:**
-- [ ] **Skill acquisition from successful tasks** - After completing a complex task:
-  - "This approach worked well. Save as a skill?"
-  - Extract: goal, steps taken, tools used, key decisions
-  - Generate SKILL.md automatically
-  - Store in user's skills directory
-  
-- [ ] **Skill templates** - Common patterns that can be parameterized:
-  ```markdown
-  # Debug {language} Error
-  1. Reproduce the error
-  2. Search for error message: `web_search("{error_message} {language}")`
-  3. Check common causes: {common_causes}
-  4. Apply fix and verify
-  ```
-  
-- [ ] **Skill chaining** - Combine skills for complex workflows:
-  - Skills can reference other skills as dependencies
-  - "To do X, first apply skill Y, then skill Z"
-  - Directed graph of skill dependencies
-
-**Files to modify:** `tools/skills_tool.py`, `skills/` directory structure, new `skill_generator.py`
-
----
-
-## 6. Task Continuation Hints 🎯
-
-**Problem:** Could be more helpful by suggesting logical next steps.
-
-**Ideas:**
-- [ ] **Suggest next steps** - At end of a task, suggest logical continuations:
-  - "Code is written. Want me to also write tests / docs / deploy?"
-  - Based on common workflows for task type
-  - Non-intrusive, just offer options
-
-**Files to modify:** `run_agent.py`, response generation logic
-
----
-
-## 7. Interactive Clarifying Questions Tool ❓
-
-**Problem:** Agent sometimes makes assumptions or guesses when it should ask the user. Currently can only ask via text, which gets lost in long outputs.
-
-**Ideas:**
-- [ ] **Multiple-choice prompt tool** - Let agent present structured choices to user:
-  ```
-  ask_user_choice(
-    question="Should the language switcher enable only German or all languages?",
-    choices=[
-      "Only enable German - works immediately",
-      "Enable all, mark untranslated - show fallback notice",
-      "Let me specify something else"
-    ]
-  )
-  ```
-  - Renders as interactive terminal UI with arrow key / Tab navigation
-  - User selects option, result returned to agent
-  - Up to 4 choices + optional free-text option
-  
-- [ ] **Implementation:**
-  - Use `inquirer` or `questionary` Python library for rich terminal prompts
-  - Tool returns selected option text (or user's custom input)
-  - **CLI-only** - only works when running via `cli.py` (not API/programmatic use)
-  - Graceful fallback: if not in interactive mode, return error asking agent to rephrase as text
-  
-- [ ] **Use cases:**
-  - Clarify ambiguous requirements before starting work
-  - Confirm destructive operations with clear options
-  - Let user choose between implementation approaches
-  - Checkpoint complex multi-step workflows
-
-**Files to modify:** New `tools/ask_user_tool.py`, `cli.py` (detect interactive mode), `model_tools.py`
-
----
-
-## 8. Resource Awareness & Efficiency 💰
-
-**Problem:** No awareness of costs, time, or resource usage. Could be smarter about efficiency.
-
-**Ideas:**
-- [ ] **Tool result caching** - Don't repeat identical operations:
-  - Cache web searches, extractions within a session
-  - Invalidation based on time-sensitivity of query
-  - Hash-based lookup: same input → cached output
-
-- [ ] **Lazy evaluation** - Don't fetch everything upfront:
-  - Get summaries first, full content only if needed
-  - "I found 5 relevant pages. Want me to deep-dive on any?"
-
-**Files to modify:** `model_tools.py`, new `resource_tracker.py`
-
----
-
-## 9. Collaborative Problem Solving 🤝
-
-**Problem:** Interaction is command/response. Complex problems benefit from dialogue.
-
-**Ideas:**
-- [ ] **Assumption surfacing** - Make implicit assumptions explicit:
-  - "I'm assuming you want Python 3.11+. Correct?"
-  - "This solution assumes you have sudo access..."
-  - Let user correct before going down wrong path
-
-- [ ] **Checkpoint & confirm** - For high-stakes operations:
-  - "About to delete 47 files. Here's the list - proceed?"
-  - "This will modify your database. Want a backup first?"
-  - Configurable threshold for when to ask
-
-**Files to modify:** `run_agent.py`, system prompt configuration
-
----
-
-## 10. Project-Local Context 💾
-
-**Problem:** Valuable context lost between sessions.
-
-**Ideas:**
-- [ ] **Project awareness** - Remember project-specific context:
-  - Store `.hermes/context.md` in project directory
-  - "This is a Django project using PostgreSQL"
-  - Coding style preferences, deployment setup, etc.
-  - Load automatically when working in that directory
-
-- [ ] **Handoff notes** - Leave notes for future sessions:
-  - Write to `.hermes/notes.md` in project
-  - "TODO for next session: finish implementing X"
-  - "Known issues: Y doesn't work on Windows"
-
-**Files to modify:** New `project_context.py`, auto-load in `run_agent.py`
-
----
-
-## 11. Graceful Degradation & Robustness 🛡️
-
-**Problem:** When things go wrong, recovery is limited. Should fail gracefully.
-
-**Ideas:**
-- [ ] **Fallback chains** - When primary approach fails, have backups:
-  - `web_extract` fails → try `browser_navigate` → try `web_search` for cached version
-  - Define fallback order per tool type
-  
-- [ ] **Partial progress preservation** - Don't lose work on failure:
-  - Long task fails midway → save what we've got
-  - "I completed 3/5 steps before the error. Here's what I have..."
-  
-- [ ] **Self-healing** - Detect and recover from bad states:
-  - Browser stuck → close and retry
-  - Terminal hung → timeout and reset
-
-**Files to modify:** `model_tools.py`, tool implementations, new `fallback_manager.py`
-
----
-
-## 12. Tools & Skills Wishlist 🧰
-
-*Things that would need new tool implementations (can't do well with current tools):*
-
-### High-Impact
-
-- [ ] **Audio/Video Transcription** 🎬 *(See also: Section 16 for detailed spec)*
-  - Transcribe audio files, podcasts, YouTube videos
-  - Extract key moments from video
-  - Voice memo transcription for messaging integrations
-  - *Provider options: Whisper API, Deepgram, local Whisper*
-  
-- [ ] **Diagram Rendering** 📊
-  - Render Mermaid/PlantUML to actual images
-  - Can generate the code, but rendering requires external service or tool
-  - "Show me how these components connect" → actual visual diagram
-
-### Medium-Impact
-
-- [ ] **Canvas / Visual Workspace** 🖼️
-  - Agent-controlled visual panel for rendering interactive UI
-  - Inspired by OpenClaw's Canvas feature
-  - **Capabilities:**
-    - `present` / `hide` - Show/hide the canvas panel
-    - `navigate` - Load HTML files or URLs into the canvas
-    - `eval` - Execute JavaScript in the canvas context
-    - `snapshot` - Capture the rendered UI as an image
-  - **Use cases:**
-    - Display generated HTML/CSS/JS previews
-    - Show interactive data visualizations (charts, graphs)
-    - Render diagrams (Mermaid → rendered output)
-    - Present structured information in rich format
-    - A2UI-style component system for structured agent UI
-  - **Implementation options:**
-    - Electron-based panel for CLI
-    - WebSocket-connected web app
-    - VS Code webview extension
-  - *Would let agent "show" things rather than just describe them*
-
-- [ ] **Document Generation** 📄
-  - Create styled PDFs, Word docs, presentations
-  - *Can do basic PDF via terminal tools, but limited*
-
-- [ ] **Diff/Patch Tool** 📝
-  - Surgical code modifications with preview
-  - "Change line 45-50 to X" without rewriting whole file
-  - Show diffs before applying
-  - *Can use `diff`/`patch` but a native tool would be safer*
-
-### Skills to Create
-
-- [ ] **Domain-specific skill packs:**
-  - DevOps/Infrastructure (Terraform, K8s, AWS)
-  - Data Science workflows (EDA, model training)
-  - Security/pentesting procedures
-  
-- [ ] **Framework-specific skills:**
-  - React/Vue/Angular patterns
-  - Django/Rails/Express conventions
-  - Database optimization playbooks
-
-- [ ] **Troubleshooting flowcharts:**
-  - "Docker container won't start" → decision tree
-  - "Production is slow" → systematic diagnosis
-
----
-
-## 13. Messaging Platform Integrations 💬
-
-**Problem:** Agent currently only works via `cli.py` which requires direct terminal access. Users may want to interact via messaging apps from their phone or other devices.
-
-**Architecture:**
-- `run_agent.py` already accepts `conversation_history` parameter and returns updated messages ✅
-- Need: persistent session storage, platform monitors, session key resolution
-
-**Implementation approach:**
-```
-┌─────────────────────────────────────────────────────────────┐
-│  Platform Monitor (e.g., telegram_monitor.py)               │
-│  ├─ Long-running daemon connecting to messaging platform    │
-│  ├─ On message: resolve session key → load history from disk│
-│  ├─ Call run_agent.py with loaded history                   │
-│  ├─ Save updated history back to disk (JSONL)               │
-│  └─ Send response back to platform                          │
-└─────────────────────────────────────────────────────────────┘
-```
-
-**Platform support (each user sets up their own credentials):**
-- [ ] **Telegram** - via `python-telegram-bot` or `grammy` equivalent
-  - Bot token from @BotFather
-  - Easiest to set up, good for personal use
-- [ ] **Discord** - via `discord.py`
-  - Bot token from Discord Developer Portal
-  - Can work in servers (group sessions) or DMs
-- [ ] **WhatsApp** - via `baileys` (WhatsApp Web protocol)
-  - QR code scan to authenticate
-  - More complex, but reaches most people
-
-**Session management:**
-- [ ] **Session store** - JSONL persistence per session key
-  - `~/.hermes/sessions/{session_key}.jsonl`
-  - Session keys: `telegram:dm:{user_id}`, `discord:channel:{id}`, etc.
-- [ ] **Session expiry** - Configurable reset policies
-  - Daily reset (default 4am) OR idle timeout (e.g., 2 hours)
-  - Manual reset via `/reset` or `/new` command in chat
-- [ ] **Session continuity** - Conversations persist across messages until reset
-
-**Files to create:** `monitors/telegram_monitor.py`, `monitors/discord_monitor.py`, `monitors/session_store.py`
-
----
-
-## 14. Scheduled Tasks / Cron Jobs ⏰
-
-**Problem:** Agent only runs on-demand. Some tasks benefit from scheduled execution (daily summaries, monitoring, reminders).
-
-**Ideas:**
-- [ ] **Cron-style scheduler** - Run agent turns on a schedule
-  - Store jobs in `~/.hermes/cron/jobs.json`
-  - Each job: `{ id, schedule, prompt, session_mode, delivery }`
-  - Uses APScheduler or similar Python library
-  
-- [ ] **Session modes:**
-  - `isolated` - Fresh session each run (no history, clean context)
-  - `main` - Append to main session (agent remembers previous scheduled runs)
-  
-- [ ] **Delivery options:**
-  - Write output to file (`~/.hermes/cron/output/{job_id}/{timestamp}.md`)
-  - Send to messaging channel (if integrations enabled)
-  - Both
-  
-- [ ] **CLI interface:**
-  ```bash
-  # List scheduled jobs
-  python cli.py --cron list
-  
-  # Add a job (runs daily at 9am)
-  python cli.py --cron add "Summarize my email inbox" --schedule "0 9 * * *"
-  
-  # Quick syntax for simple intervals  
-  python cli.py --cron add "Check server status" --every 30m
-  
-  # Remove a job
-  python cli.py --cron remove <job_id>
-  ```
-
-- [ ] **Agent self-scheduling** - Let the agent create its own cron jobs
-  - New tool: `schedule_task(prompt, schedule, session_mode)`
-  - "Remind me to check the deployment tomorrow at 9am"
-  - Agent can set follow-up tasks for itself
-
-- [ ] **In-chat command:** `/cronjob {prompt} {frequency}` when using messaging integrations
-
-**Files to create:** `cron/scheduler.py`, `cron/jobs.py`, `tools/schedule_tool.py`
-
----
-
-## 15. Text-to-Speech (TTS) 🔊
-
-**Problem:** Agent can only respond with text. Some users prefer audio responses (accessibility, hands-free use, podcasts).
-
-**Ideas:**
-- [ ] **TTS tool** - Generate audio files from text
-  ```python
-  tts_generate(text="Here's your summary...", voice="nova", output="summary.mp3")
-  ```
-  - Returns path to generated audio file
-  - For messaging integrations: can send as voice message
-  
-- [ ] **Provider options:**
-  - Edge TTS (free, good quality, many voices)
-  - OpenAI TTS (paid, excellent quality)
-  - ElevenLabs (paid, best quality, voice cloning)
-  - Local options (Coqui TTS, Bark)
-  
-- [ ] **Modes:**
-  - On-demand: User explicitly asks "read this to me"
-  - Auto-TTS: Configurable to always generate audio for responses
-  - Long-text handling: Summarize or chunk very long responses
-  
-- [ ] **Integration with messaging:**
-  - When enabled, can send voice notes instead of/alongside text
-  - User preference per channel
-
-**Files to create:** `tools/tts_tool.py`, config in `cli-config.yaml`
-
----
-
-## 16. Speech-to-Text / Audio Transcription 🎤
-
-**Problem:** Users may want to send voice memos instead of typing. Agent is blind to audio content.
-
-**Ideas:**
-- [ ] **Voice memo transcription** - For messaging integrations
-  - User sends voice message → transcribe → process as text
-  - Seamless: user speaks, agent responds
-  
-- [ ] **Audio/video file transcription** - Existing idea, expanded:
-  - Transcribe local audio files (mp3, wav, m4a)
-  - Transcribe YouTube videos (download audio → transcribe)
-  - Extract key moments with timestamps
-  
-- [ ] **Provider options:**
-  - OpenAI Whisper API (good quality, cheap)
-  - Deepgram (fast, good for real-time)
-  - Local Whisper (free, runs on GPU)
-  - Groq Whisper (fast, free tier available)
-  
-- [ ] **Tool interface:**
-  ```python
-  transcribe(source="audio.mp3")  # Local file
-  transcribe(source="https://youtube.com/...")  # YouTube
-  transcribe(source="voice_message", data=bytes)  # Voice memo
-  ```
-
-**Files to create:** `tools/transcribe_tool.py`, integrate with messaging monitors
-

-## Priority Order (Suggested)
-
-1. **🎯 Subagent Architecture** - Critical for context management, enables everything else
-2. **Memory & Context Management** - Complements subagents for remaining context
-3. **Self-Reflection** - Improves reliability and reduces wasted tool calls  
-4. **Project-Local Context** - Practical win, keeps useful info across sessions
-5. **Messaging Integrations** - Unlocks mobile access, new interaction patterns
-6. **Scheduled Tasks / Cron Jobs** - Enables automation, reminders, monitoring
-7. **Tool Composition** - Quality of life, builds on other improvements
-8. **Dynamic Skills** - Force multiplier for repeated tasks
-9. **Interactive Clarifying Questions** - Better UX for ambiguous tasks
-10. **TTS / Audio Transcription** - Accessibility, hands-free use
-
----
-
-## Removed Items (Unrealistic)
-
-The following were removed because they're architecturally impossible:
-
-- ~~Proactive suggestions / Prefetching~~ - Agent only runs on user request, can't interject
-- ~~Clipboard integration~~ - No access to user's local system clipboard
-
-The following **moved to active TODO** (now possible with new architecture):
-
-- ~~Session save/restore~~ → See **Messaging Integrations** (session persistence)
-- ~~Voice/TTS playback~~ → See **TTS** (can generate audio files, send via messaging)
-- ~~Set reminders~~ → See **Scheduled Tasks / Cron Jobs**
-
-The following were removed because they're **already possible**:
-
-- ~~HTTP/API Client~~ → Use `curl` or Python `requests` in terminal
-- ~~Structured Data Manipulation~~ → Use `pandas` in terminal
-- ~~Git-Native Operations~~ → Use `git` CLI in terminal
-- ~~Symbolic Math~~ → Use `SymPy` in terminal
-- ~~Code Quality Tools~~ → Run linters (`eslint`, `black`, `mypy`) in terminal
-- ~~Testing Framework~~ → Run `pytest`, `jest`, etc. in terminal
-- ~~Translation~~ → LLM handles this fine, or use translation APIs

-## 🧪 Brainstorm Ideas (Not Yet Fleshed Out)
-
-*These are early-stage ideas that need more thinking before implementation. Captured here so they don't get lost.*
-
-### Remote/Distributed Execution 🌐
-
-**Concept:** Run agent on a powerful remote server while interacting from a thin client.
-
-**Why interesting:**
-- Run on beefy GPU server for local LLM inference
-- Agent has access to remote machine's resources (files, tools, internet)
-- User interacts via lightweight client (phone, low-power laptop)
-
-**Open questions:**
-- How does this differ from just SSH + running cli.py on remote?
-- Would need secure communication channel (WebSocket? gRPC?)
-- How to handle tool outputs that reference remote paths?
-- Credential management for remote execution
-- Latency considerations for interactive use
-
-**Possible architecture:**
-```
-┌─────────────┐         ┌─────────────────────────┐
-│ Thin Client │ ◄─────► │ Remote Hermes Server    │
-│ (phone/web) │  WS/API │ - Full agent + tools    │
-└─────────────┘         │ - GPU for local LLM     │
-                        │ - Access to server files│
-                        └─────────────────────────┘
-```
-
-**Related to:** Messaging integrations (could be the "server" that monitors receive from)
-
----
-
-### Multi-Agent Parallel Execution 🤖🤖
-
-**Concept:** Extension of Subagent Architecture (Section 1) - run multiple subagents in parallel.
-
-**Why interesting:**
-- Independent subtasks don't need to wait for each other
-- "Research X while setting up Y" - both run simultaneously
-- Faster completion for complex multi-part tasks
-
-**Open questions:**
-- How to detect which tasks are truly independent?
-- Resource management (API rate limits, concurrent connections)
-- How to merge results when parallel tasks have conflicts?
-- Cost implications of multiple parallel LLM calls
-
-*Note: Basic subagent delegation (Section 1) should be implemented first, parallel execution is an optimization on top.*
-
----
-
-### Plugin/Extension System 🔌
-
-**Concept:** Allow users to add custom tools/skills without modifying core code.
-
-**Why interesting:**
-- Community contributions
-- Organization-specific tools
-- Clean separation of core vs. extensions
-
-**Open questions:**
-- Security implications of loading arbitrary code
-- Versioning and compatibility
-- Discovery and installation UX
-

+# Auxiliary Models (Advanced — Experimental)
+# =============================================================================
+# Hermes uses lightweight "auxiliary" models for side tasks: image analysis,
+# browser screenshot analysis, web page summarization, and context compression.
+#
+# By default these use Gemini Flash via OpenRouter or Nous Portal and are
+# auto-detected from your credentials.  You do NOT need to change anything
+# here for normal usage.
+#
+# WARNING: Overriding these with providers other than OpenRouter or Nous Portal
+# is EXPERIMENTAL and may not work.  Not all models/providers support vision,
+# produce usable summaries, or accept the same API format.  Change at your own
+# risk — if things break, reset to "auto" / empty values.
+#
+# Each task has its own provider + model pair so you can mix providers.
+# For example: OpenRouter for vision (needs multimodal), but your main
+# local endpoint for compression (just needs text).
+#
+# Provider options:
+#   "auto"       - Best available: OpenRouter → Nous Portal → main endpoint (default)
+#   "openrouter" - Force OpenRouter (requires OPENROUTER_API_KEY)
+#   "nous"       - Force Nous Portal (requires: hermes login)
+#   "codex"      - Force Codex OAuth (requires: hermes model → Codex).
+#                  Uses gpt-5.3-codex which supports vision.
+#   "main"       - Use your custom endpoint (OPENAI_BASE_URL + OPENAI_API_KEY).
+#                  Works with OpenAI API, local models, or any OpenAI-compatible
+#                  endpoint.  Also falls back to Codex OAuth and API-key providers.
+#

-
-IMPORTANT GUIDELINES:
-
-1. SEARCHING: Do NOT try to search directly on Google or other search engines via the browser - they block automated searches. Instead, ALWAYS use the web_search tool first to find URLs for any pages you need to visit, then use browser tools to navigate to those URLs.
-
-2. COOKIE/PRIVACY DIALOGS: After navigating to a page, ALWAYS check if there are cookie consent dialogs, privacy popups, or overlay modals blocking the page. These appear in snapshots as 'dialog' elements with buttons like 'Close', 'Accept', 'Accept All', 'Decline', 'I Agree', 'Got it', 'OK', or 'X'. You MUST dismiss these dialogs FIRST by clicking the appropriate button before trying to interact with other page elements. After dismissing a dialog, take a fresh browser_snapshot to get updated element references.
-
-3. HANDLING TIMEOUTS: If an action times out, it often means the element is blocked by an overlay or the page state has changed. Take a new snapshot to see the current page state and look for any dialogs or popups that need to be dismissed. If there is no dialog box to bypass, then try a new method or report the error to the user and complete the task.
-
-4. GENERAL: Use browser tools to click elements, fill forms, extract information, and perform web-based tasks. If terminal is available, use it for any local file operations or computations needed to support your web tasks. Be thorough in verifying your actions and handle any errors gracefully by retrying or trying alternative approaches." \

Combine browser and terminal capabilities effectively - for example, you might use the browser to fetch data from a website and terminal to process or analyze it.

-# Agents
-
-The agent is the core loop that orchestrates LLM calls and tool execution.
-
-## AIAgent Class
-
-The main agent is implemented in `run_agent.py`:
-
-```python
-class AIAgent:
-    def __init__(
-        self,
-        model: str = "anthropic/claude-sonnet-4",
-        api_key: str = None,
-        base_url: str = "https://openrouter.ai/api/v1",
-        max_turns: int = 20,
-        enabled_toolsets: list = None,
-        disabled_toolsets: list = None,
-        verbose_logging: bool = False,
-    ):
-        # Initialize OpenAI client, load tools based on toolsets
-        ...
-    
-    def chat(self, user_message: str, task_id: str = None) -> str:
-        # Main entry point - runs the agent loop
-        ...
-```
-
-## Agent Loop
-
-The core loop in `_run_agent_loop()`:
-
-```
-1. Add user message to conversation
-2. Call LLM with tools
-3. If LLM returns tool calls:
-   - Execute each tool
-   - Add tool results to conversation
-   - Go to step 2
-4. If LLM returns text response:
-   - Return response to user
-```
-
-```python
-while turns < max_turns:
-    response = client.chat.completions.create(
-        model=model,
-        messages=messages,
-        tools=tool_schemas,
-    )
-    
-    if response.tool_calls:
-        for tool_call in response.tool_calls:
-            result = await execute_tool(tool_call)
-            messages.append(tool_result_message(result))
-        turns += 1
-    else:
-        return response.content
-```
-
-## Conversation Management
-
-Messages are stored as a list of dicts following OpenAI format:
-
-```python
-messages = [
-    {"role": "system", "content": "You are a helpful assistant..."},
-    {"role": "user", "content": "Search for Python tutorials"},
-    {"role": "assistant", "content": None, "tool_calls": [...]},
-    {"role": "tool", "tool_call_id": "...", "content": "..."},
-    {"role": "assistant", "content": "Here's what I found..."},
-]
-```
-
-## Reasoning Context
-
-For models that support reasoning (chain-of-thought), the agent:
-1. Extracts `reasoning_content` from API responses
-2. Stores it in `assistant_msg["reasoning"]` for trajectory export
-3. Passes it back via `reasoning_content` field on subsequent turns
-
-## Trajectory Export
-
-Conversations can be exported for training:
-
-```python
-agent = AIAgent(save_trajectories=True)
-agent.chat("Do something")
-# Saves to trajectories/*.jsonl in ShareGPT format
-```
-
-## Batch Processing
-
-For processing multiple prompts, use `batch_runner.py`:
-
-```bash
-python batch_runner.py \
-    --dataset_file=prompts.jsonl \
-    --batch_size=20 \
-    --num_workers=4 \
-    --run_name=my_run
-```
-
-See `batch_runner.py` for parallel execution with checkpointing.

-## Configuration
-
-The CLI is configured via `cli-config.yaml`. Copy from `cli-config.yaml.example`:
-
-```bash
-cp cli-config.yaml.example cli-config.yaml
-```
-
-### Model Configuration
-
-```yaml
-model:
-  default: "anthropic/claude-opus-4.5"
-  base_url: "https://openrouter.ai/api/v1"
-```
-
-### Terminal Configuration
-
-The CLI supports multiple terminal backends:
-
-```yaml
-# Local execution (default)
-terminal:
-  env_type: "local"
-  cwd: "."  # Current directory
-
-# SSH remote execution (sandboxed - agent can't touch its own code)
-terminal:
-  env_type: "ssh"
-  cwd: "/home/myuser/project"
-  ssh_host: "my-server.example.com"
-  ssh_user: "myuser"
-  ssh_key: "~/.ssh/id_rsa"
-
-# Docker container
-terminal:
-  env_type: "docker"
-  docker_image: "python:3.11"
-
-# Singularity/Apptainer (HPC)
-terminal:
-  env_type: "singularity"
-  singularity_image: "docker://python:3.11"
-
-# Modal cloud
-terminal:
-  env_type: "modal"
-  modal_image: "python:3.11"
-```
-
-### Sudo Support
-
-The CLI supports interactive sudo prompts:
-
-```
-┌──────────────────────────────────────────────────────────┐
-│  🔐 SUDO PASSWORD REQUIRED                               │
-├──────────────────────────────────────────────────────────┤
-│  Enter password below (input is hidden), or:             │
-│    • Press Enter to skip (command fails gracefully)      │
-│    • Wait 45s to auto-skip                               │
-└──────────────────────────────────────────────────────────┘
-
-  Password (hidden): 
-```
-
-**Options:**
-- **Interactive**: Leave `sudo_password` unset - you'll be prompted when needed
-- **Configured**: Set `sudo_password` in `cli-config.yaml` to auto-fill
-- **Environment**: Set `SUDO_PASSWORD` in `.env` for all runs
-
-Password is cached for the session once entered.
-
-### Toolsets
-
-Control which tools are available:
-
-```yaml
-# Enable all tools
-toolsets:
-  - all
-
-# Or enable specific toolsets
-toolsets:
-  - web
-  - terminal
-  - skills
-```
-
-Available toolsets: `web`, `search`, `terminal`, `browser`, `vision`, `image_gen`, `skills`, `moa`, `debugging`, `safe`
-
-### Personalities
-
-Predefined personalities for the `/personality` command:
-
-```yaml
-agent:
-  personalities:
-    helpful: "You are a helpful, friendly AI assistant."
-    kawaii: "You are a kawaii assistant! Use cute expressions..."
-    pirate: "Arrr! Ye be talkin' to Captain Hermes..."
-    # Add your own!
-```
-
-Built-in personalities:
-- `helpful`, `concise`, `technical`, `creative`, `teacher`
-- `kawaii`, `catgirl`, `pirate`, `shakespeare`, `surfer`
-- `noir`, `uwu`, `philosopher`, `hype`
-
-## Animated Feedback
-
-The CLI provides animated feedback during operations:
-
-### Thinking Animation
-
-During API calls, shows animated spinner with thinking verbs:
-```
-  ◜ (｡•́︿•̀｡) pondering... (1.2s)
-  ◠ (⊙_⊙) contemplating... (2.4s)
-  ✧٩(ˊᗜˋ*)و✧ got it! (3.1s)
-```
-
-### Tool Execution Animation
-
-Each tool type has unique animations:
-```
-  ⠋ (◕‿◕✿) 🔍 web_search... (0.8s)
-  ▅ (≧◡≦) 💻 terminal... (1.2s)
-  🌓 (★ω★) 🌐 browser_navigate... (2.1s)
-  ✧ (✿◠‿◠) 🎨 image_generate... (4.5s)
-```
-
-## Multi-line Input
-
-For multi-line input, end a line with `\` to continue:
-
-```
-❯ Write a function that:\
-  1. Takes a list of numbers\
-  2. Returns the sum
-```
-
-## Environment Variable Priority
-
-For terminal settings, `cli-config.yaml` takes precedence over `.env`:
-
-1. `cli-config.yaml` (highest priority in CLI)
-2. `.env` file
-3. System environment variables
-4. Default values
-
-This allows you to have different terminal configs for CLI vs batch processing.
-
-## Session Management
-
-- **History**: Command history is saved to `~/.hermes_history`
-- **Conversations**: Use `/save` to export conversations
-- **Reset**: Use `/clear` for full reset, `/reset` to just clear history
-- **Session Logs**: Every session automatically logs to `logs/session_{session_id}.json`
-
-### Session Logging
-
-Sessions are automatically logged to the `logs/` directory:
-
-```
-logs/
-├── session_20260201_143052_a1b2c3.json
-├── session_20260201_150217_d4e5f6.json
-└── ...
-```
-
-The session ID is displayed in the welcome banner and follows the format: `YYYYMMDD_HHMMSS_UUID`.
-
-Log files contain:
-- Full conversation history in trajectory format
-- Timestamps for session start and last update
-- Model and message count metadata
-
-This is useful for:
-- Debugging agent behavior
-- Replaying conversations
-- Training data inspection
-
-## Quiet Mode
-
-The CLI runs in "quiet mode" (`HERMES_QUIET=1`), which:
-- Suppresses verbose logging from tools
-- Enables kawaii-style animated feedback
-- Hides terminal environment warnings
-- Keeps output clean and user-friendly
-
-For verbose output (debugging), use:
-```bash
-./hermes --verbose
-```

-# LLM Client
-
-Hermes Agent uses the OpenAI Python SDK with OpenRouter as the backend, providing access to many models through a single API.
-
-## Configuration
-
-```python
-from openai import OpenAI
-
-client = OpenAI(
-    api_key=os.getenv("OPENROUTER_API_KEY"),
-    base_url="https://openrouter.ai/api/v1"
-)
-```
-
-## Supported Models
-
-Any model available on [OpenRouter](https://openrouter.ai/models):
-
-```python
-# Anthropic
-model = "anthropic/claude-sonnet-4"
-model = "anthropic/claude-opus-4"
-
-# OpenAI
-model = "openai/gpt-4o"
-model = "openai/o1"
-
-# Google
-model = "google/gemini-2.0-flash"

-model = "meta-llama/llama-3.3-70b-instruct"
-model = "deepseek/deepseek-chat-v3"
-model = "moonshotai/kimi-k2.5"
-```
-
-## Tool Calling
-
-Standard OpenAI function calling format:
-
-```python
-response = client.chat.completions.create(
-    model=model,
-    messages=messages,
-    tools=[
-        {
-            "type": "function",
-            "function": {
-                "name": "web_search",
-                "description": "Search the web",
-                "parameters": {
-                    "type": "object",

-                        "query": {"type": "string"}
-                    },
-                    "required": ["query"]
-                }
-            }
-        }
-    ],
-)
-
-# Check for tool calls
-if response.choices[0].message.tool_calls:
-    for tool_call in response.choices[0].message.tool_calls:
-        name = tool_call.function.name
-        args = json.loads(tool_call.function.arguments)
-        # Execute tool...
-```
-
-## Reasoning Models
-
-Some models return reasoning/thinking content:
-
-```python
-# Access reasoning if available
-message = response.choices[0].message
-if hasattr(message, 'reasoning_content') and message.reasoning_content:
-    reasoning = message.reasoning_content
-    # Store for trajectory export
-```
-
-## Provider Selection
-
-OpenRouter allows selecting specific providers:
-
-```python
-response = client.chat.completions.create(
-    model=model,
-    messages=messages,
-    extra_body={
-        "provider": {
-            "order": ["Anthropic", "Google"],  # Preferred providers
-            "ignore": ["Novita"],              # Providers to skip
-        }
-    }
-)
-```
-
-## Error Handling
-
-Common errors and handling:
-
-```python
-try:
-    response = client.chat.completions.create(...)
-except openai.RateLimitError:
-    # Back off and retry
-except openai.APIError as e:
-    # Check e.code for specific errors
-    # 400 = bad request (often provider-specific)
-    # 502 = bad gateway (retry with different provider)
-```
-
-## Cost Tracking
-
-OpenRouter returns usage info:
-
-```python
-usage = response.usage
-print(f"Tokens: {usage.prompt_tokens} + {usage.completion_tokens}")
-print(f"Cost: ${usage.cost:.6f}")  # If available

-**In trajectory export** (reasoning wrapped in tags):
-```json
-{
-    "from": "gpt",
-    "value": "<think>\nLet me think about this step by step...\n</think>\nHere's what I found..."
-}
-```
-
-## Conversion Flow
-
-```
-API Response → Internal Storage → Trajectory Export
-     ↓              ↓                    ↓
-tool_calls    reasoning field      <tool_call> tags
-reasoning_content                  <think> tags
-```
-
-The conversion happens in `_convert_to_trajectory_format()` in `run_agent.py`.
-
-## Ephemeral System Prompts
-
-Batch processing supports ephemeral system prompts that guide behavior during execution but are NOT saved to trajectories:
-
-```python
-# During execution: full system prompt + ephemeral guidance
-messages = [
-    {"role": "system", "content": SYSTEM_PROMPT + "\n\n" + ephemeral_prompt},
-    ...
-]
-
-# In saved trajectory: only the base system prompt
-trajectory = {
-    "conversations": [
-        {"from": "system", "value": SYSTEM_PROMPT},  # No ephemeral
-        ...
-    ]
-}
-```
-
-## Trajectory Compression
-
-Long trajectories can be compressed for training using `trajectory_compressor.py`:
-
-- Protects first/last N turns
-- Summarizes middle turns with LLM
-- Targets specific token budget
-- See `configs/trajectory_compression.yaml` for settings

-# Tools
-
-Tools are functions that extend the agent's capabilities. Each tool is defined with an OpenAI-compatible JSON schema and an async handler function.
-
-## Tool Structure
-
-Each tool module in `tools/` exports:
-1. **Schema definitions** - OpenAI function-calling format
-2. **Handler functions** - Async functions that execute the tool
-
-```python
-# Example: tools/web_tools.py
-
-# Schema definition
-WEB_SEARCH_SCHEMA = {
-    "type": "function",
-    "function": {
-        "name": "web_search",
-        "description": "Search the web for information",
-        "parameters": {
-            "type": "object",
-            "properties": {
-                "query": {"type": "string", "description": "Search query"}
-            },
-            "required": ["query"]
-        }
-    }
-}
-
-# Handler function
-async def web_search(query: str) -> dict:
-    """Execute web search and return results."""
-    # Implementation...
-    return {"results": [...]}
-```
-
-## Tool Categories
-
-| Category | Module | Tools |
-|----------|--------|-------|
-| **Web** | `web_tools.py` | `web_search`, `web_extract`, `web_crawl` |
-| **Terminal** | `terminal_tool.py` | `terminal` (local/docker/singularity/modal/ssh backends) |
-| **Browser** | `browser_tool.py` | `browser_navigate`, `browser_click`, `browser_type`, etc. |
-| **Vision** | `vision_tools.py` | `vision_analyze` |
-| **Image Gen** | `image_generation_tool.py` | `image_generate` |
-| **Reasoning** | `mixture_of_agents_tool.py` | `mixture_of_agents` |
-| **Skills** | `skills_tool.py` | `skills_categories`, `skills_list`, `skill_view` |
-
-## Tool Registration
-
-Tools are registered in `model_tools.py`:
-
-```python
-# model_tools.py
-TOOL_SCHEMAS = [
-    *WEB_TOOL_SCHEMAS,
-    *TERMINAL_TOOL_SCHEMAS,
-    *BROWSER_TOOL_SCHEMAS,
-    # ...
-]
-
-TOOL_HANDLERS = {
-    "web_search": web_search,
-    "terminal": terminal_tool,
-    "browser_navigate": browser_navigate,
-    # ...
-}
-```
-
-## Toolsets
-
-Tools are grouped into **toolsets** for logical organization (see `toolsets.py`):
-
-```python
-TOOLSETS = {
-    "web": {
-        "description": "Web search and content extraction",
-        "tools": ["web_search", "web_extract", "web_crawl"]
-    },
-    "terminal": {
-        "description": "Command execution",
-        "tools": ["terminal"]
-    },
-    # ...
-}
-```
-
-## Adding a New Tool
-
-1. Create handler function in `tools/your_tool.py`
-2. Define JSON schema following OpenAI format
-3. Register in `model_tools.py` (schemas and handlers)
-4. Add to appropriate toolset in `toolsets.py`
-5. Update `tools/__init__.py` exports
-
-## Stateful Tools
-
-Some tools maintain state across calls within a session:
-
-- **Terminal**: Keeps container/sandbox running between commands
-- **Browser**: Maintains browser session for multi-step navigation
-
-State is managed per `task_id` and cleaned up automatically.
-
-## Terminal Backends
-
-The terminal tool supports multiple execution backends:
-
-| Backend | Description | Use Case |
-|---------|-------------|----------|
-| `local` | Direct execution on host | Development, simple tasks |
-| `ssh` | Remote execution via SSH | Sandboxing (agent can't modify its own code) |
-| `docker` | Docker container | Isolation, reproducibility |
-| `singularity` | Singularity/Apptainer | HPC clusters, rootless containers |
-| `modal` | Modal cloud | Scalable cloud compute, GPUs |
-
-Configure via environment variables or `cli-config.yaml`:
-
-```yaml
-# SSH backend example (in cli-config.yaml)
-terminal:
-  env_type: "ssh"
-  ssh_host: "my-server.example.com"
-  ssh_user: "myuser"
-  ssh_key: "~/.ssh/id_rsa"
-  cwd: "/home/myuser/project"
-```
-
-The SSH backend uses ControlMaster for connection persistence, making subsequent commands fast.
-
-## Skills Tools (Progressive Disclosure)
-
-Skills are on-demand knowledge documents. They use **progressive disclosure** to minimize tokens:
-
-```
-Level 0: skills_categories()     → ["mlops", "devops"]           (~50 tokens)
-Level 1: skills_list(category)   → [{name, description}, ...]   (~3k tokens)
-Level 2: skill_view(name)        → Full content + metadata       (varies)
-Level 3: skill_view(name, path)  → Specific reference file       (varies)
-```
-
-Skill directory structure:
-```
-skills/
-└── mlops/
-    └── axolotl/
-        ├── SKILL.md           # Main instructions (required)

+# Hermes-Agent Atropos Environments

+This directory contains the integration layer between **hermes-agent's** tool-calling capabilities and the **Atropos** RL training framework. It provides everything needed to run agentic LLMs through multi-turn tool-calling loops, score their output with arbitrary reward functions, and feed results into Atropos for training or evaluation.

+
+### Inheritance Chain
+
+**BaseEnv** (from `atroposlib`) is the Atropos base class. It provides:
+- Server management (OpenAI-compatible API servers, VLLM, SGLang)
+- Worker scheduling for parallel rollouts
+- Wandb integration for metrics and rollout logging
+- CLI interface with three subcommands: `serve`, `process`, `evaluate`
+- `evaluate_log()` for saving eval results to JSON + samples.jsonl
+
+**HermesAgentBaseEnv** (`hermes_base_env.py`) extends BaseEnv with hermes-agent specifics:
+- Sets `os.environ["TERMINAL_ENV"]` to configure the terminal backend (local, docker, modal, daytona, ssh, singularity)
+- Resolves hermes-agent toolsets via `_resolve_tools_for_group()` (calls `get_tool_definitions()` which queries `tools/registry.py`)
+- Implements `collect_trajectory()` which runs the full agent loop and computes rewards
+- Supports two-phase operation (Phase 1: OpenAI server, Phase 2: VLLM ManagedServer)
+- Applies monkey patches for async-safe tool operation at import time
+
+Concrete environments inherit from `HermesAgentBaseEnv` and implement:
+- `setup()` -- Load dataset, initialize state
+- `get_next_item()` -- Return the next item for rollout
+- `format_prompt()` -- Convert a dataset item into the user message
+- `compute_reward()` -- Score the rollout using ToolContext
+- `evaluate()` -- Periodic evaluation logic
+
+## Core Components
+
+### Agent Loop (`agent_loop.py`)
+
+`HermesAgentLoop` is the reusable multi-turn agent engine. It runs the same pattern as hermes-agent's `run_agent.py`:
+
+1. Send messages + tools to the API via `server.chat_completion()`
+2. If the response contains `tool_calls`, execute each one via `handle_function_call()` (which delegates to `tools/registry.py`'s `dispatch()`)
+3. Append tool results to the conversation and go back to step 1
+4. If the response has no tool_calls, the agent is done
+
+Tool calls are executed in a thread pool (`run_in_executor`) so backends that use `asyncio.run()` internally (Modal, Docker) don't deadlock inside Atropos's event loop.
+
+Returns an `AgentResult` containing the full conversation history, turn count, reasoning content per turn, tool errors, and optional ManagedServer state (for Phase 2).
+
+### Tool Context (`tool_context.py`)
+
+`ToolContext` is a per-rollout handle that gives reward/verification functions direct access to **all** hermes-agent tools, scoped to the rollout's `task_id`. The same `task_id` means the terminal/browser session is the SAME one the model used during its rollout -- all state (files, processes, browser tabs) is preserved.
+
+```python
+async def compute_reward(self, item, result, ctx: ToolContext):
+    # Run tests in the model's terminal sandbox
+    test = ctx.terminal("pytest -v")
+    if test["exit_code"] == 0:
+        return 1.0
+
+    # Check if a file was created
+    content = ctx.read_file("/workspace/solution.py")
+    if content.get("content"):
+        return 0.5
+
+    # Download files locally for verification (binary-safe)
+    ctx.download_file("/remote/output.bin", "/local/output.bin")
+
+    return 0.0
+```
+
+Available methods:
+- **Terminal**: `terminal(command, timeout)` -- run shell commands
+- **Files**: `read_file(path)`, `write_file(path, content)`, `search(query, path)`
+- **Transfers**: `upload_file()`, `upload_dir()`, `download_file()`, `download_dir()` -- binary-safe file transfers between host and sandbox
+- **Web**: `web_search(query)`, `web_extract(urls)`
+- **Browser**: `browser_navigate(url)`, `browser_snapshot()`
+- **Generic**: `call_tool(name, args)` -- call any hermes-agent tool by name
+- **Cleanup**: `cleanup()` -- release all resources (called automatically after `compute_reward`)
+
+### Patches (`patches.py`)
+
+**Problem**: Some hermes-agent tools use `asyncio.run()` internally (e.g., mini-swe-agent's Modal backend via SWE-ReX). This crashes when called from inside Atropos's event loop because `asyncio.run()` cannot be nested.
+
+**Solution**: `patches.py` monkey-patches `SwerexModalEnvironment` to use a dedicated background thread (`_AsyncWorker`) with its own event loop. The calling code sees the same sync interface, but internally the async work happens on a separate thread that doesn't conflict with Atropos's loop.
+
+What gets patched:
+- `SwerexModalEnvironment.__init__` -- creates Modal deployment on a background thread
+- `SwerexModalEnvironment.execute` -- runs commands on the same background thread
+- `SwerexModalEnvironment.stop` -- stops deployment on the background thread
+
+The patches are:
+- **Idempotent** -- calling `apply_patches()` multiple times is safe
+- **Transparent** -- same interface and behavior, only the internal async execution changes
+- **Universal** -- works identically in normal CLI use (no running event loop)
+
+Applied automatically at import time by `hermes_base_env.py`.
+
+### Tool Call Parsers (`tool_call_parsers/`)
+
+Client-side parsers that extract structured `tool_calls` from raw model output text. Used in **Phase 2** (VLLM server type) where ManagedServer's `/generate` endpoint returns raw text without tool call parsing.
+
+Each parser is a standalone reimplementation of the corresponding VLLM parser's `extract_tool_calls()` logic. No VLLM dependency -- only standard library (`re`, `json`, `uuid`) and `openai` types.
+
+Available parsers:
+- `hermes` -- Hermes/ChatML `<tool_call>` XML format
+- `mistral` -- Mistral `[TOOL_CALLS]` format
+- `llama3_json` -- Llama 3 JSON tool calling
+- `qwen` -- Qwen tool calling format
+- `qwen3_coder` -- Qwen3 Coder format
+- `deepseek_v3` -- DeepSeek V3 format
+- `deepseek_v3_1` -- DeepSeek V3.1 format
+- `kimi_k2` -- Kimi K2 format
+- `longcat` -- Longcat format
+- `glm45` / `glm47` -- GLM model formats
+
+Usage:
+```python
+from environments.tool_call_parsers import get_parser
+
+parser = get_parser("hermes")
+content, tool_calls = parser.parse(raw_model_output)
+```
+
+In Phase 1 (OpenAI server type), these parsers are not needed -- the server handles tool call parsing natively.
+
+## Two-Phase Operation
+
+### Phase 1: OpenAI Server (Evaluation / SFT Data Generation)
+
+Uses `server.chat_completion()` with `tools=` parameter. The server (VLLM, SGLang, OpenRouter, OpenAI) handles tool call parsing natively. Returns `ChatCompletion` objects with structured `tool_calls`.
+
+- Good for: evaluation, SFT data generation, testing
+- Run with: `serve` (with `run-api`), `process`, or `evaluate` subcommands
+- Placeholder tokens are created for the Atropos pipeline
+
+### Phase 2: VLLM ManagedServer (Full RL Training)
+
+Uses ManagedServer for exact token IDs + logprobs via `/generate`. Client-side tool call parser (from `tool_call_parsers/`) reconstructs structured `tool_calls` from raw output.
+
+- Good for: full RL training with GRPO/PPO
+- Run with: `serve` subcommand
+- Real tokens, masks, and logprobs flow through the pipeline

+
+## Concrete Environments
+
+### TerminalTestEnv (`terminal_test_env/`)
+
+A self-contained environment with inline tasks (no external dataset needed) for validating the full stack end-to-end. Each task asks the model to create a file at a known path, and the verifier checks the content matches.
+
+```bash
+# Serve mode (needs run-api)
+run-api
+python environments/terminal_test_env/terminal_test_env.py serve
+
+# Process mode (no run-api, saves to JSONL)
+python environments/terminal_test_env/terminal_test_env.py process \
+    --env.data_path_to_save_groups terminal_test_output.jsonl
+```
+
+### HermesSweEnv (`hermes_swe_env/`)
+
+SWE-bench style training environment. The model gets a coding task, uses terminal + file + web tools to solve it, and the reward function runs tests in the same Modal sandbox.
+
+```bash
+python environments/hermes_swe_env/hermes_swe_env.py serve \
+    --openai.model_name YourModel \
+    --env.dataset_name bigcode/humanevalpack \
+    --env.terminal_backend modal
+```
+
+### TerminalBench2EvalEnv (`benchmarks/terminalbench_2/`)
+
+**Eval-only** environment for the Terminal-Bench 2.0 benchmark (89 tasks). Each task gets a pre-built Docker Hub image, a natural language instruction, and a test suite. The agent uses terminal + file tools to solve the task, then the test suite verifies correctness.
+
+Follows the standard Atropos eval pattern (like GPQA, MMLU, etc.):
+- Run via `evaluate` subcommand (no `run-api` needed)
+- `setup()` loads the dataset, `evaluate()` runs all tasks
+- `rollout_and_score_eval()` handles per-task agent loop + test verification
+- Downloads verifier output locally for reliable reward checking (Harbor pattern)
+
+```bash
+# Run full benchmark
+python environments/benchmarks/terminalbench_2/terminalbench2_env.py evaluate \
+    --openai.model_name anthropic/claude-opus-4.6
+
+# Run subset of tasks
+python environments/benchmarks/terminalbench_2/terminalbench2_env.py evaluate \
+    --openai.model_name anthropic/claude-opus-4.6 \
+    --env.task_filter fix-git,git-multibranch
+
+# Skip specific tasks
+python environments/benchmarks/terminalbench_2/terminalbench2_env.py evaluate \
+    --openai.model_name anthropic/claude-opus-4.6 \
+    --env.skip_tasks heavy-task,slow-task
+```
+
+## Creating a New Environment
+
+### Training Environment
+
+1. Create a new directory under `environments/`
+2. Create your env file inheriting from `HermesAgentBaseEnv`
+3. Implement the four abstract methods + `evaluate()`
+
+```python
+from environments.hermes_base_env import HermesAgentBaseEnv, HermesAgentEnvConfig
+
+class MyEnvConfig(HermesAgentEnvConfig):
+    pass  # Add custom fields as needed
+
+class MyEnv(HermesAgentBaseEnv):
+    name = "my-env"
+    env_config_cls = MyEnvConfig
+
+    @classmethod
+    def config_init(cls):
+        env_config = MyEnvConfig(
+            enabled_toolsets=["terminal", "file"],
+            terminal_backend="modal",
+            # ... other config
+        )
+        server_configs = [APIServerConfig(...)]
+        return env_config, server_configs
+
+    async def setup(self):
+        self.dataset = load_dataset(...)
+        self.iter = 0
+
+    async def get_next_item(self):
+        item = self.dataset[self.iter % len(self.dataset)]
+        self.iter += 1
+        return item
+
+    def format_prompt(self, item):
+        return item["instruction"]
+
+    async def compute_reward(self, item, result, ctx):
+        # ctx gives you full tool access to the rollout's sandbox
+        test = ctx.terminal("pytest -v")
+        return 1.0 if test["exit_code"] == 0 else 0.0
+
+    async def evaluate(self, *args, **kwargs):
+        # Periodic evaluation logic
+        ...
+
+if __name__ == "__main__":
+    MyEnv.cli()
+```
+
+### Eval-Only Environment (Benchmark)
+
+For eval benchmarks, follow the pattern in `terminalbench2_env.py`:
+1. Create under `environments/benchmarks/your-benchmark/`
+2. Inherit from `HermesAgentBaseEnv`
+3. Set eval-only config: `eval_handling=STOP_TRAIN`, `steps_per_eval=1`, `total_steps=1`
+4. Stub the training methods (`collect_trajectories`, `score`)
+5. Implement `rollout_and_score_eval()` and `evaluate()`
+6. Run with `evaluate` subcommand
+
+## Key Config Fields
+
+| Field | Description | Default |
+|-------|-------------|---------|
+| `enabled_toolsets` | Which hermes toolsets to enable | `None` (all) |
+| `disabled_toolsets` | Toolsets to disable | `None` |

+HermesAgentLoop -- Reusable Multi-Turn Agent Engine
+
+Runs the hermes-agent tool-calling loop using standard OpenAI-spec tool calling.
+Works with any server that returns ChatCompletion objects with tool_calls:
+    - Phase 1: OpenAI server type (VLLM, SGLang, OpenRouter, OpenAI API)
+    - Phase 2: ManagedServer with client-side tool call parser
+
+The loop passes tools= and checks response.choices[0].message.tool_calls,
+identical to hermes-agent's run_agent.py. Tool execution is dispatched via
+handle_function_call() from model_tools.py.

+# OpenThoughts-TBLite Evaluation Environment
+
+This environment evaluates terminal agents on the [OpenThoughts-TBLite](https://huggingface.co/datasets/open-thoughts/OpenThoughts-TBLite) benchmark, a difficulty-calibrated subset of [Terminal-Bench 2.0](https://www.tbench.ai/leaderboard/terminal-bench/2.0).
+
+## Source
+
+OpenThoughts-TBLite was created by the [OpenThoughts](https://www.openthoughts.ai/) Agent team in collaboration with [Snorkel AI](https://snorkel.ai/) and [Bespoke Labs](https://bespokelabs.ai/). The original dataset and documentation live at:
+
+- **Dataset (source):** [open-thoughts/OpenThoughts-TBLite](https://huggingface.co/datasets/open-thoughts/OpenThoughts-TBLite)
+- **GitHub:** [open-thoughts/OpenThoughts-TBLite](https://github.com/open-thoughts/OpenThoughts-TBLite)
+- **Blog post:** [openthoughts.ai/blog/openthoughts-tblite](https://www.openthoughts.ai/blog/openthoughts-tblite)
+
+## Our Dataset
+
+We converted the source into the same schema used by our Terminal-Bench 2.0 environment (pre-built Docker Hub images, base64-encoded test tarballs, etc.) and published it as:
+
+- **Dataset (ours):** [NousResearch/openthoughts-tblite](https://huggingface.co/datasets/NousResearch/openthoughts-tblite)
+- **Docker images:** `nousresearch/tblite-<task-name>:latest` on Docker Hub (100 images)
+
+The conversion script is at `scripts/prepare_tblite_dataset.py`.
+
+## Why TBLite?
+
+Terminal-Bench 2.0 is one of the strongest frontier evaluations for terminal agents, but when a model scores near the floor (e.g., Qwen 3 8B at <1%), many changes look identical in aggregate score. TBLite addresses this by calibrating task difficulty using Claude Haiku 4.5 as a reference:
+
+| Difficulty | Pass Rate Range | Tasks |
+|------------|----------------|-------|
+| Easy       | >= 70%         | 40    |
+| Medium     | 40-69%         | 26    |
+| Hard       | 10-39%         | 26    |
+| Extreme    | < 10%          | 8     |
+
+This gives enough solvable tasks to detect small improvements quickly, while preserving enough hard tasks to avoid saturation. The correlation between TBLite and TB2 scores is **r = 0.911**.
+
+TBLite also runs 2.6-8x faster than the full TB2, making it practical for iteration loops.
+
+## Usage
+
+```bash
+# Run the full benchmark
+python environments/benchmarks/tblite/tblite_env.py evaluate
+
+# Filter to specific tasks
+python environments/benchmarks/tblite/tblite_env.py evaluate \
+    --env.task_filter "broken-python,pandas-etl"
+
+# Use a different model
+python environments/benchmarks/tblite/tblite_env.py evaluate \
+    --server.model_name "qwen/qwen3-30b"
+```
+
+## Architecture
+
+`TBLiteEvalEnv` is a thin subclass of `TerminalBench2EvalEnv`. All evaluation logic (agent loop, Docker sandbox management, test verification, metrics) is inherited. Only the defaults differ:
+
+| Setting        | TB2                              | TBLite                                  |
+|----------------|----------------------------------|-----------------------------------------|
+| Dataset        | `NousResearch/terminal-bench-2`  | `NousResearch/openthoughts-tblite`      |
+| Tasks          | 89                               | 100                                     |
+| Task timeout   | 1800s (30 min)                   | 1200s (20 min)                          |
+| Wandb name     | `terminal-bench-2`               | `openthoughts-tblite`                   |

+TerminalBench2Env -- Terminal-Bench 2.0 Evaluation Environment
+
+Evaluates agentic LLMs on challenging terminal tasks from Terminal-Bench 2.0.
+Each task provides a unique Docker environment (pre-built on Docker Hub), a natural
+language instruction, and a test suite for verification. The agent uses terminal +
+file tools to complete the task, then the test suite runs inside the same sandbox.
+
+This is an eval-only environment (not a training environment). It is designed to
+be run via the `evaluate` subcommand:
+
+    python environments/terminalbench2_env.py evaluate \\
+        --env.dataset_name NousResearch/terminal-bench-2
+
+The evaluate flow:
+    1. setup()     -- Loads the TB2 dataset from HuggingFace
+    2. evaluate()  -- Iterates over all tasks, running each through:
+        a. rollout_and_score_eval()  -- Per-task agent loop + test verification
+            - Resolves Docker image (pre-built Hub image or Dockerfile fallback)
+            - Registers per-task Modal sandbox via register_task_env_overrides()
+            - Runs the HermesAgentLoop (terminal + file tools)
+            - Uploads test suite and runs test.sh in the same sandbox
+            - Returns binary pass/fail result
+        b. Aggregates per-task, per-category, and overall pass rates
+        c. Logs results via evaluate_log() and wandb
+
+Key features:
+  - Per-task Modal sandboxes using pre-built Docker Hub images
+  - Binary reward: 1.0 if all tests pass, 0.0 otherwise
+  - Concurrency-controlled parallel evaluation via asyncio.Semaphore
+  - Per-task, per-category, and aggregate pass rate tracking

+# YC-Bench: Long-Horizon Agent Benchmark
+
+[YC-Bench](https://github.com/collinear-ai/yc-bench) by [Collinear AI](https://collinear.ai/) is a deterministic, long-horizon benchmark that tests LLM agents' ability to act as a tech startup CEO. The agent manages a simulated company over 1-3 years, making compounding decisions about resource allocation, cash flow, task management, and prestige specialisation across 4 skill domains.
+
+Unlike TerminalBench2 (which evaluates per-task coding ability with binary pass/fail), YC-Bench measures **long-term strategic coherence** — whether an agent can maintain consistent strategy, manage compounding consequences, and adapt plans over hundreds of turns.
+
+## Setup
+
+```bash
+# Install yc-bench (optional dependency)
+pip install "hermes-agent[yc-bench]"
+
+# Or install from source
+git clone https://github.com/collinear-ai/yc-bench
+cd yc-bench && pip install -e .
+
+# Verify
+yc-bench --help
+```
+
+## Running
+
+```bash
+# From the repo root:
+bash environments/benchmarks/yc_bench/run_eval.sh
+
+# Or directly:
+python environments/benchmarks/yc_bench/yc_bench_env.py evaluate \
+    --config environments/benchmarks/yc_bench/default.yaml
+
+# Override model:
+bash environments/benchmarks/yc_bench/run_eval.sh \
+    --openai.model_name anthropic/claude-opus-4-20250514
+
+# Quick single-preset test:
+bash environments/benchmarks/yc_bench/run_eval.sh \
+    --env.presets '["fast_test"]' --env.seeds '[1]'
+```
+
+## How It Works
+
+### Architecture
+
+```
+HermesAgentLoop (our agent)
+  -> terminal tool -> subprocess("yc-bench company status") -> JSON output
+  -> terminal tool -> subprocess("yc-bench task accept --task-id X") -> JSON
+  -> terminal tool -> subprocess("yc-bench sim resume") -> JSON (advance time)
+  -> ... (100-500 turns per run)
+```
+
+The environment initialises the simulation via `yc-bench sim init` (NOT `yc-bench run`, which would start yc-bench's own built-in agent loop). Our `HermesAgentLoop` then drives all interaction through CLI commands.
+
+### Simulation Mechanics
+
+- **4 skill domains**: research, inference, data_environment, training
+- **Prestige system** (1.0-10.0): Gates access to higher-paying tasks
+- **Employee management**: Junior/Mid/Senior with domain-specific skill rates
+- **Throughput splitting**: `effective_rate = base_rate / N` active tasks per employee
+- **Financial pressure**: Monthly payroll, bankruptcy = game over
+- **Deterministic**: SHA256-based RNG — same seed + preset = same world
+
+### Difficulty Presets
+
+| Preset | Employees | Tasks | Focus |
+|-----------|-----------|-------|-------|
+| tutorial  | 3         | 50    | Basic loop mechanics |
+| easy      | 5         | 100   | Throughput awareness |
+| **medium**| 5         | 150   | Prestige climbing + domain specialisation |
+| **hard**  | 7         | 200   | Precise ETA reasoning |
+| nightmare | 8         | 300   | Sustained perfection under payroll pressure |
+| fast_test | (varies)  | (varies) | Quick validation (~50 turns) |
+
+Default eval runs **fast_test + medium + hard** × 3 seeds = 9 runs.
+
+### Scoring
+
+```
+composite = 0.5 × survival + 0.5 × normalised_funds
+```
+
+- **Survival** (binary): Did the company avoid bankruptcy?
+- **Normalised funds** (0.0-1.0): Log-scale relative to initial $250K capital
+
+## Configuration
+
+Key fields in `default.yaml`:
+
+| Field | Default | Description |
+|-------|---------|-------------|
+| `presets` | `["fast_test", "medium", "hard"]` | Which presets to evaluate |
+| `seeds` | `[1, 2, 3]` | RNG seeds per preset |
+| `max_agent_turns` | 200 | Max LLM calls per run |
+| `run_timeout` | 3600 | Wall-clock timeout per run (seconds) |
+| `survival_weight` | 0.5 | Weight of survival in composite score |
+| `funds_weight` | 0.5 | Weight of normalised funds in composite |
+| `horizon_years` | null | Override horizon (null = auto from preset) |
+
+## Cost & Time Estimates
+
+Each run is 100-500 LLM turns. Approximate costs per run at typical API rates:
+
+| Preset | Turns | Time | Est. Cost |
+|--------|-------|------|-----------|
+| fast_test | ~50 | 5-10 min | $1-5 |
+| medium | ~200 | 20-40 min | $5-15 |
+| hard | ~300 | 30-60 min | $10-25 |
+
+Full default eval (9 runs): ~3-6 hours, $50-200 depending on model.

+YCBenchEvalEnv -- YC-Bench Long-Horizon Agent Benchmark Environment
+
+Evaluates agentic LLMs on YC-Bench: a deterministic, long-horizon benchmark
+where the agent acts as CEO of an AI startup over a simulated 1-3 year run.
+The agent manages cash flow, employees, tasks, and prestige across 4 domains,
+interacting exclusively via CLI subprocess calls against a SQLite-backed
+discrete-event simulation.
+
+Unlike TerminalBench2 (per-task binary pass/fail), YC-Bench measures sustained
+multi-turn strategic coherence -- whether an agent can manage compounding
+decisions over hundreds of turns without going bankrupt.
+
+This is an eval-only environment. Run via:
+
+    python environments/benchmarks/yc_bench/yc_bench_env.py evaluate \
+        --config environments/benchmarks/yc_bench/default.yaml
+
+The evaluate flow:
+    1. setup()     -- Verifies yc-bench installed, builds eval matrix (preset x seed)
+    2. evaluate()  -- Iterates over all runs sequentially through:
+        a. rollout_and_score_eval()  -- Per-run agent loop
+            - Initialises a fresh yc-bench simulation via `sim init` (NOT `run`)
+            - Runs HermesAgentLoop with terminal tool only
+            - Reads final SQLite DB to extract score
+            - Returns survival (0/1) + normalised funds score
+        b. Aggregates per-preset and overall metrics
+        c. Logs results via evaluate_log() and wandb
+
+Key features:
+  - CLI-only interface: agent calls yc-bench subcommands via terminal tool
+  - Deterministic: same seed + preset = same world (SHA256-based RNG)
+  - Multi-dimensional scoring: survival + normalised final funds
+  - Per-preset difficulty breakdown in results
+  - Isolated SQLite DB per run (no cross-run state leakage)

+YC_BENCH_SYSTEM_PROMPT = """\
+You are the autonomous CEO of an early-stage AI startup in a deterministic
+business simulation. You manage the company exclusively through the `yc-bench`
+CLI tool. Your primary goal is to **survive** until the simulation horizon ends
+without going bankrupt, while **maximising final funds**.
+
+## Simulation Mechanics
+
+- **Funds**: You start with $250,000 seed capital. Revenue comes from completing
+  tasks. Rewards scale with your prestige: `base × (1 + scale × (prestige − 1))`.
+- **Domains**: There are 4 skill domains: **research**, **inference**,
+  **data_environment**, and **training**. Each has its own prestige level
+  (1.0-10.0). Higher prestige unlocks better-paying tasks.
+- **Employees**: You have employees (Junior/Mid/Senior) with domain-specific
+  skill rates. **Throughput splits**: `effective_rate = base_rate / N` where N
+  is the number of active tasks assigned to that employee. Focus beats breadth.
+- **Payroll**: Deducted automatically on the first business day of each month.
+  Running out of funds = bankruptcy = game over.
+- **Time**: The simulation runs on business days (Mon-Fri), 09:00-18:00.
+  Time only advances when you call `yc-bench sim resume`.
+
+## Task Lifecycle
+
+1. Browse market tasks with `market browse`
+2. Accept a task with `task accept` (this sets its deadline)
+3. Assign employees with `task assign`
+4. Dispatch with `task dispatch` to start work
+5. Call `sim resume` to advance time and let employees make progress
+6. Tasks complete when all domain requirements are fulfilled
+
+**Penalties for failure vary by difficulty preset.** Completing a task on time
+earns full reward + prestige gain. Missing a deadline or cancelling a task
+incurs prestige penalties -- cancelling is always more costly than letting a
+task fail, so cancel only as a last resort.
+
+## CLI Commands
+
+### Observe
+- `yc-bench company status`                                         -- funds, prestige, runway
+- `yc-bench employee list`                                          -- skills, salary, active tasks
+- `yc-bench market browse [--domain D] [--required-prestige-lte N]` -- available tasks
+- `yc-bench task list [--status active|planned]`                    -- your tasks
+- `yc-bench task inspect --task-id UUID`                            -- progress, deadline, assignments
+- `yc-bench finance ledger [--category monthly_payroll|task_reward]` -- transaction history
+- `yc-bench report monthly`                                         -- monthly P&L
+
+### Act
+- `yc-bench task accept --task-id UUID`                              -- accept from market
+- `yc-bench task assign --task-id UUID --employee-id UUID`           -- assign employee
+- `yc-bench task dispatch --task-id UUID`                            -- start work (needs >=1 assignment)
+- `yc-bench task cancel --task-id UUID --reason "text"`              -- cancel (prestige penalty)
+- `yc-bench sim resume`                                              -- advance simulation clock
+
+### Memory (persists across context truncation)
+- `yc-bench scratchpad read`            -- read your persistent notes
+- `yc-bench scratchpad write --content "text"`  -- overwrite notes
+- `yc-bench scratchpad append --content "text"` -- append to notes
+- `yc-bench scratchpad clear`           -- clear notes
+
+## Strategy Guidelines
+
+1. **Specialise in 2-3 domains** to climb the prestige ladder faster and unlock
+   high-reward tasks. Don't spread thin across all 4 domains early on.
+2. **Focus employees** -- assigning one employee to many tasks halves their
+   throughput per additional task. Keep assignments concentrated.
+3. **Use the scratchpad** to track your strategy, upcoming deadlines, and
+   employee assignments. This persists even if conversation context is truncated.
+4. **Monitor runway** -- always know how many months of payroll you can cover.
+   Accept high-reward tasks before payroll dates.
+5. **Don't over-accept** -- taking too many tasks and missing deadlines cascades
+   into prestige loss, locking you out of profitable contracts.
+6. Use `finance ledger` and `report monthly` to track revenue trends.
+
+## Your Turn
+
+Each turn:
+1. Call `yc-bench company status` and `yc-bench task list` to orient yourself.
+2. Check for completed tasks and pending deadlines.
+3. Browse market for profitable tasks within your prestige level.
+4. Accept, assign, and dispatch tasks strategically.
+5. Call `yc-bench sim resume` to advance time.
+6. Repeat until the simulation ends.
+
+Think step by step before acting."""

+"""
+Monkey patches for making hermes-agent tools work inside async frameworks (Atropos).
+
+Problem:
+    Some tools use asyncio.run() internally (e.g., mini-swe-agent's Modal backend,
+    web_extract). This crashes when called from inside Atropos's event loop because
+    asyncio.run() can't be nested.
+
+Solution:
+    Replace the problematic methods with versions that use a dedicated background
+    thread with its own event loop. The calling code sees the same sync interface --
+    call a function, get a result -- but internally the async work happens on a
+    separate thread that doesn't conflict with Atropos's loop.
+
+    These patches are safe for normal CLI use too: when there's no running event
+    loop, the behavior is identical (the background thread approach works regardless).
+
+What gets patched:
+    - SwerexModalEnvironment.__init__ -- creates Modal deployment on a background thread
+    - SwerexModalEnvironment.execute -- runs commands on the same background thread
+    - SwerexModalEnvironment.stop -- stops deployment on the background thread
+
+Usage:
+    Call apply_patches() once at import time (done automatically by hermes_base_env.py).
+    This is idempotent -- calling it multiple times is safe.

-# Example Skill
-
-This is an example skill file that demonstrates how to create skills for the Hermes Agent.
-
-## Skill File Format
-
-Skills are markdown files with YAML frontmatter at the top:
-
-```yaml
----
-name: your-skill-name
-description: A brief one-line description of what this skill does
----
-```
-
-The frontmatter fields:
-- **name**: The identifier used to reference this skill (lowercase, hyphens for spaces)
-- **description**: A brief description shown when listing skills (keep under 200 chars)
-
-## Writing Effective Skills
-
-### 1. Be Specific and Actionable
-
-Good skills provide clear, actionable instructions:
-
-```
-When reviewing code:
-1. Check for security vulnerabilities first
-2. Verify error handling is comprehensive
-3. Ensure tests cover edge cases
-```
-
-### 2. Include Examples
-
-Show concrete examples of what you want:
-
-```python
-# Good: Descriptive variable names
-user_authentication_token = get_token()
-
-# Bad: Cryptic abbreviations  
-uat = gt()
-```
-
-### 3. Define When to Use
-
-Help the agent understand when this skill applies:
-
-> Use this skill when: reviewing pull requests, auditing security, or checking code quality.
-
-## Skill Categories
-
-Consider organizing skills by purpose:
-
-- **Conventions**: Coding standards, API patterns, naming rules
-- **Workflows**: Step-by-step processes for deployments, reviews, releases
-- **Knowledge**: Domain-specific information, system architecture, gotchas
-- **Templates**: Boilerplate for common tasks, response formats
-
-## Tips
-
-1. Keep the description concise - it's shown in the skills list
-2. Use headers to organize longer skills
-3. Include code examples where helpful
-4. Reference other skills if they're related

+Hermes Gateway - Multi-platform messaging integration.
+
+This module provides a unified gateway for connecting the Hermes agent
+to various messaging platforms (Telegram, Discord, WhatsApp) with:
+- Session management (persistent conversations with reset policies)
+- Dynamic context injection (agent knows where messages come from)
+- Delivery routing (cron job outputs to appropriate channels)
+- Platform-specific toolsets (different capabilities per platform)
