feat: devex help, add Makefile, ruff, pre-commit, and modernize CI

cap-drop ALL removes DAC_OVERRIDE, which root needs to write to
bind-mounted directories owned by the host user (uid 1000). This
broke persistent Docker sandboxes — the container couldn't write
to /workspace or /root.

Add back the minimum capabilities needed:
- DAC_OVERRIDE: root can write to bind-mounted dirs owned by host user
- CHOWN: package managers (pip, npm, apt) need to set file ownership
- FOWNER: needed for operations on files owned by other users

Still drops all other capabilities (NET_RAW, SYS_ADMIN, etc.) and
keeps no-new-privileges. Security boundary is the container itself.

Verified end-to-end: create files → destroy container → new container
with same task_id → files persist on host and are accessible in the
new container.

-Hermes-Agent is an agent harness for LLMs.
-
-When building, the tool functionality is in the tools/ directory, where each specific tool (or in some cases, tools that are built for the same execution category or api) are placed in a script each their own.
-
-Each tool is then consolidated in the model_tools.py file in the repo root.
-
-There is also a way to consolidate sets of tools in toolsets.py for the agent to use.
-
-The primary agent runner code is in run_agent, but other runners could be developed using the tools and framework.
-
-Always ensure consistency between tools, the model_tools.py and toolsets.py when changing any of them, otherwise they could become desynced in a way that is detrimental to functionality.
-
-The expected pathway for using API keys is to setup and place them in a .env file in the repo root.
-
-Test scripts will be placed in tests/
-
-The run_agent loop is setup to:
-- Process the enabled toolsets to provide to the model,
-- Pipe in a prompt or problem from the input to the agent,
-- Loop the LLM each time it calls a tool, until the model decides no more tools are needed and provides a natural language response,
-- Return that response.
-
-There are additional caveats for logging, where we restructure the "tools" as a system prompt for storage later into a format that can be used and handled properly later.

+# SSH REMOTE EXECUTION (for TERMINAL_ENV=ssh)
+# =============================================================================
+# Run terminal commands on a remote server via SSH.
+# Agent code stays on your machine, commands execute remotely.
+#
+# SECURITY BENEFITS:
+# - Agent cannot read your .env file (API keys protected)
+# - Agent cannot modify its own code

+# Works with: local, docker, singularity, modal, and ssh backends.
+# 
+# SECURITY WARNING: Password stored in plaintext. Only use on trusted machines.
+# 
+# ALTERNATIVES:
+# - For SSH backend: Configure passwordless sudo on the remote server
+# - For containers: Run as root inside the container (no sudo needed)

+
+## AIAgent Class (run_agent.py)
+
+```python
+class AIAgent:
+    def __init__(self,
+        model: str = "anthropic/claude-opus-4.6",
+        max_iterations: int = 90,
+        enabled_toolsets: list = None,
+        disabled_toolsets: list = None,
+        quiet_mode: bool = False,
+        save_trajectories: bool = False,
+        platform: str = None,           # "cli", "telegram", etc.
+        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.
+
+---
+
+## Development Commands
+
+```bash
+make setup          # First time: .venv + deps + pre-commit hooks
+make check          # Lint + test (mirrors CI — run before pushing)
+make lint           # Ruff check
+make fmt            # Ruff format + auto-fix
+make test           # Full test suite (~2500 tests, ~2 min)
+make test-fast      # Tests with fail-fast (-x)
+make test-watch     # Rerun tests on file changes
+make dev-cli        # Auto-restart CLI on file changes
+make dev-gateway    # Auto-restart gateway on file changes
+```
+
+For targeted testing, use `pytest` directly:
+
+```bash
+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/gateway/ -q               # Gateway tests
+python -m pytest tests/tools/ -q                 # Tool-level tests
+```
+
+Formatting is enforced by **ruff** (config in `pyproject.toml`). Pre-commit hooks run on every commit.

+# 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.
+3. **Security hardening** — shell injection, prompt injection, path traversal, privilege escalation. See [Security](#security-considerations).
+4. **Performance and robustness** — retry logic, error handling, graceful degradation.
+5. **New skills** — but only broadly useful ones. See [Should it be a Skill or a Tool?](#should-it-be-a-skill-or-a-tool)
+6. **New tools** — rarely needed. Most capabilities should be skills. See below.
+7. **Documentation** — fixes, clarifications, new examples.

+
+## 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
+
+- **Formatting**: Enforced by **ruff** (config in `pyproject.toml`). Run `make fmt` to auto-fix, `make lint` to check. Pre-commit hooks handle this automatically.
+- **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.

+**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.
 
-## Setup
+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.
 
-### 1. Install Dependencies
-```bash
-# Create and activate virtual environment (recommended)
-python3 -m venv venv
-source venv/bin/activate  # On Windows: venv\Scripts\activate
+<table>

-```
-
-### 2. 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:**
-- `ANTHROPIC_API_KEY` - Main agent model (get at: https://console.anthropic.com/)
-- `FIRECRAWL_API_KEY` - Web tools (get at: https://firecrawl.dev/)
-- `NOUS_API_KEY` - Vision & reasoning tools (get at: https://inference-api.nousresearch.com/)
-- `MORPH_API_KEY` - Terminal tools (get at: https://morph.so/)
-- `FAL_KEY` - Image generation (get at: https://fal.ai/)
-- `OPENAI_API_KEY` - Optional, for some Hecate features
-
-See `.env.example` for all available configuration options including debug settings and terminal tool configuration.
-
-## 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
+## Quick Install
 
 ```bash
-# Use a predefined toolset
-python run_agent.py --enabled_toolsets=research --query "Find latest AI papers"
-
-# Combine multiple toolsets
-python run_agent.py --enabled_toolsets=web,vision --query "Analyze this website"
-
-# Enable all toolsets explicitly (same as omitting the flag)
-python run_agent.py --enabled_toolsets=all --query "Do web research and run commands if helpful"
-
-# 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
+curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
 ```
 
-For detailed documentation on toolsets, see `TOOLSETS_README.md`.
+Works on Linux, macOS, and WSL2. The installer handles everything — Python, Node.js, dependencies, and the `hermes` command. No prerequisites except git.
 
-## Basic Usage
+> **Windows:** Native Windows is not supported. Please install [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install) and run the command above.
 
-### Default (all tools enabled)
-```bash
-python run_agent.py \
-  --query "search up the latest docs on jit in python 3.13 and write me basic example that's not in their docs. profile its perf" \
-  --max_turns 20 \
-  --model claude-sonnet-4-20250514 \
-  --base_url https://api.anthropic.com/v1/ \
-  --api_key $ANTHROPIC_API_KEY
-```
-
-### With specific toolset
-```bash
-python run_agent.py \
-  --query "Debug this Python error" \
-  --enabled_toolsets=debugging \
-  --model claude-sonnet-4-20250514 \
-  --api_key $ANTHROPIC_API_KEY
-```
-
-### Python API
-```python
-from run_agent import AIAgent
-
-# Use a specific toolset
-agent = AIAgent(
-    model="claude-opus-4-20250514",
-    enabled_toolsets=["research"]
-)
-response = agent.chat("Find information about quantum computing")
-
-# Create custom toolset at runtime
-from toolsets import create_custom_toolset
-
-create_custom_toolset(
-    name="my_tools",
-    description="My custom toolkit",
-    tools=["web_search"],
-    includes=["terminal", "vision"]
-)
-
-agent = AIAgent(enabled_toolsets=["my_tools"])
-```
-
-## Batch Processing
-
-Process multiple prompts from a dataset in parallel with automatic checkpointing and statistics tracking:
+After installation:
 
 ```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
+source ~/.bashrc    # reload shell (or: source ~/.zshrc)
+hermes setup        # configure your LLM provider
+hermes              # start chatting!
 ```
 
-**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
+---
 
-**Quick Start:** See [QUICKSTART_BATCH.md](QUICKSTART_BATCH.md) for a 5-minute getting started guide.  
-**Full Documentation:** See [BATCH_PROCESSING.md](BATCH_PROCESSING.md) for comprehensive documentation.
+## Getting Started
 
-### 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."
+hermes              # Interactive CLI — start a conversation
+hermes model        # Switch provider or model
+hermes setup        # Re-run the setup wizard
+hermes gateway      # Start the messaging gateway (Telegram, Discord, etc.)
+hermes update       # Update to the latest version
+hermes doctor       # Diagnose any issues
 ```
 
-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.
+📖 **[Full documentation →](https://hermes-agent.nousresearch.com/docs/)**
 
-**Documentation:** See [docs/ephemeral_system_prompt.md](docs/ephemeral_system_prompt.md) for complete details.

+# - Password is cached for the session
+#
+# ALTERNATIVES:
+# - SSH backend: Configure passwordless sudo on the remote server
+# - Containers: Run as root inside the container (no sudo needed)
+# - Local: Configure /etc/sudoers for specific commands
+#

+# Context Compression (Auto-shrinks long conversations)
+# =============================================================================
+# When conversation approaches model's context limit, middle turns are
+# automatically summarized to free up space while preserving important context.
+#
+# HOW IT WORKS:
+# 1. Tracks actual token usage from API responses (not estimates)
+# 2. When prompt_tokens >= threshold% of model's context_length, triggers compression
+# 3. Protects first 3 turns (system prompt, initial request, first response)
+# 4. Protects last 4 turns (recent context is most relevant)
+# 5. Summarizes middle turns using a fast/cheap model
+# 6. Inserts summary as a user message, continues conversation seamlessly
+#
+compression:
+  # Enable automatic context compression (default: true)
+  # Set to false if you prefer to manage context manually or want errors on overflow
+  enabled: true
+  
+  # Trigger compression at this % of model's context limit (default: 0.85 = 85%)
+  # Lower values = more aggressive compression, higher values = compress later
+  threshold: 0.85
+  
+  # Model to use for generating summaries (fast/cheap recommended)
+  # This model compresses the middle turns into a concise summary.
+  # IMPORTANT: it receives the full middle section of the conversation, so it
+  # MUST support a context length at least as large as your main model's.
+  summary_model: "google/gemini-3-flash-preview"
+  
+  # Provider for the summary model (default: "auto")

+# 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.
+#
+# Model: leave empty to use the provider's default.  When empty, OpenRouter
+# uses "google/gemini-3-flash-preview" and Nous uses "gemini-3-flash".
+# Other providers pick a sensible default automatically.
+#
+# auxiliary:
+#   # Image analysis: vision_analyze tool + browser screenshots
+#   vision:
+#     provider: "auto"
+#     model: ""              # e.g. "google/gemini-2.5-flash", "openai/gpt-4o"

+# =============================================================================
+# Persistent Memory
+# =============================================================================
+# Bounded curated memory injected into the system prompt every session.
+# Two stores: MEMORY.md (agent's notes) and USER.md (user profile).
+# Character limits keep the memory small and focused. The agent manages
+# pruning -- when at the limit, it must consolidate or replace entries.
+# Disabled by default in batch_runner and RL environments.
+#
+memory:
+  # Agent's personal notes: environment facts, conventions, things learned
+  memory_enabled: true
+  
+  # User profile: preferences, communication style, expectations
+  user_profile_enabled: true
+  
+  # Character limits (~2.75 chars per token, model-independent)
+  memory_char_limit: 2200   # ~800 tokens
+  user_char_limit: 1375     # ~500 tokens
+
+  # Periodic memory nudge: remind the agent to consider saving memories
+  # every N user turns. Set to 0 to disable. Only active when memory is enabled.
+  nudge_interval: 10        # Nudge every 10 user turns (0 = disabled)
+
+  # Memory flush: give the agent one turn to save memories before context is
+  # lost (compression, /new, /reset, exit). Set to 0 to disable.
+  # For exit/reset, only fires if the session had at least this many user turns.
+  flush_min_turns: 6        # Min user turns to trigger flush on exit/reset (0 = disabled)
+
+# =============================================================================
+# Session Reset Policy (Messaging Platforms)
+# =============================================================================
+# Controls when messaging sessions (Telegram, Discord, WhatsApp, Slack) are
+# automatically cleared. Without resets, conversation context grows indefinitely
+# which increases API costs with every message.
+#
+# When a reset triggers, the agent first saves important information to its
+# persistent memory — but the conversation context is wiped. The agent starts
+# fresh but retains learned facts via its memory system.
+#
+# Users can always manually reset with /reset or /new in chat.
+#
+# Modes:
+#   "both"  - Reset on EITHER inactivity timeout or daily boundary (recommended)
+#   "idle"  - Reset only after N minutes of inactivity
+#   "daily" - Reset only at a fixed hour each day
+#   "none"  - Never auto-reset; context lives until /reset or compression kicks in
+#
+# When a reset triggers, the agent gets one turn to save important memories and
+# skills before the context is wiped. Persistent memory carries across sessions.
+#
+session_reset:
+  mode: both           # "both", "idle", "daily", or "none"
+  idle_minutes: 1440   # Inactivity timeout in minutes (default: 1440 = 24 hours)
+  at_hour: 4           # Daily reset hour, 0-23 local time (default: 4 AM)
+
+# =============================================================================
+# Skills Configuration
+# =============================================================================
+# Skills are reusable procedures the agent can load and follow. The agent can
+# also create new skills after completing complex tasks.
+#
+skills:
+  # Nudge the agent to create skills after complex tasks.
+  # Every N tool-calling iterations, remind the model to consider saving a skill.
+  # Set to 0 to disable.
+  creation_nudge_interval: 15
+
+# =============================================================================
+# Agent Behavior
+# =============================================================================
+agent:
+  # Maximum tool-calling iterations per conversation
+  # Higher = more room for complex tasks, but costs more tokens
+  # Recommended: 20-30 for focused tasks, 50-100 for open exploration
+  max_turns: 60
+  
+  # Enable verbose logging
+  verbose: false

+# 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` |
+| `distribution` | Probabilistic toolset distribution name | `None` |
+| `max_agent_turns` | Max LLM calls per rollout | `30` |
+| `agent_temperature` | Sampling temperature | `1.0` |
+| `terminal_backend` | `local`, `docker`, `modal`, `daytona`, `ssh`, `singularity` | `local` |
+| `system_prompt` | System message for the agent | `None` |
+| `tool_call_parser` | Parser name for Phase 2 | `hermes` |
+| `eval_handling` | `STOP_TRAIN`, `LIMIT_TRAIN`, `NONE` | `STOP_TRAIN` |

+# 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                                  |

+OpenThoughts-TBLite Evaluation Environment

+A lighter, faster alternative to Terminal-Bench 2.0 for iterating on terminal

+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)
+
+Requires: pip install hermes-agent[yc-bench]

+
+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

+# Adding a New Messaging Platform
+
+Checklist for integrating a new messaging platform into the Hermes gateway.
+Use this as a reference when building a new adapter — every item here is a
+real integration point that exists in the codebase. Missing any of them will
+cause broken functionality, missing features, or inconsistent behavior.
+
+---
+
+## 1. Core Adapter (`gateway/platforms/<platform>.py`)
+
+The adapter is a subclass of `BasePlatformAdapter` from `gateway/platforms/base.py`.
+
+### Required methods
+
+| Method | Purpose |
+|--------|---------|
+| `__init__(self, config)` | Parse config, init state. Call `super().__init__(config, Platform.YOUR_PLATFORM)` |
+| `connect() -> bool` | Connect to the platform, start listeners. Return True on success |
+| `disconnect()` | Stop listeners, close connections, cancel tasks |
+| `send(chat_id, text, ...) -> SendResult` | Send a text message |
+| `send_typing(chat_id)` | Send typing indicator |
+| `send_image(chat_id, image_url, caption) -> SendResult` | Send an image |
+| `get_chat_info(chat_id) -> dict` | Return `{name, type, chat_id}` for a chat |
+
+### Optional methods (have default stubs in base)
+
+| Method | Purpose |
+|--------|---------|
+| `send_document(chat_id, path, caption)` | Send a file attachment |
+| `send_voice(chat_id, path)` | Send a voice message |
+| `send_video(chat_id, path, caption)` | Send a video |
+| `send_animation(chat_id, path, caption)` | Send a GIF/animation |
+| `send_image_file(chat_id, path, caption)` | Send image from local file |
+
+### Required function
+
+```python
+def check_<platform>_requirements() -> bool:
+    """Check if this platform's dependencies are available."""
+```
+
+### Key patterns to follow
+
+- Use `self.build_source(...)` to construct `SessionSource` objects
+- Call `self.handle_message(event)` to dispatch inbound messages to the gateway
+- Use `MessageEvent`, `MessageType`, `SendResult` from base
+- Use `cache_image_from_bytes`, `cache_audio_from_bytes`, `cache_document_from_bytes` for attachments
+- Filter self-messages (prevent reply loops)
+- Filter sync/echo messages if the platform has them
+- Redact sensitive identifiers (phone numbers, tokens) in all log output
+- Implement reconnection with exponential backoff + jitter for streaming connections
+- Set `MAX_MESSAGE_LENGTH` if the platform has message size limits
+
+---
+
+## 2. Platform Enum (`gateway/config.py`)
+
+Add the platform to the `Platform` enum:
+
+```python
+class Platform(Enum):
+    ...
+    YOUR_PLATFORM = "your_platform"
+```
+
+Add env var loading in `_apply_env_overrides()`:
+
+```python
+# Your Platform
+your_token = os.getenv("YOUR_PLATFORM_TOKEN")
+if your_token:
+    if Platform.YOUR_PLATFORM not in config.platforms:
+        config.platforms[Platform.YOUR_PLATFORM] = PlatformConfig()
+    config.platforms[Platform.YOUR_PLATFORM].enabled = True
+    config.platforms[Platform.YOUR_PLATFORM].token = your_token
+```
+
+Update `get_connected_platforms()` if your platform doesn't use token/api_key
+(e.g., WhatsApp uses `enabled` flag, Signal uses `extra` dict).
+
+---
+
+## 3. Adapter Factory (`gateway/run.py`)
+
+Add to `_create_adapter()`:
+
+```python
+elif platform == Platform.YOUR_PLATFORM:
+    from gateway.platforms.your_platform import YourAdapter, check_your_requirements
+    if not check_your_requirements():
+        logger.warning("Your Platform: dependencies not met")
+        return None
+    return YourAdapter(config)
+```
+
+---
+
+## 4. Authorization Maps (`gateway/run.py`)
+
+Add to BOTH dicts in `_is_user_authorized()`:
+
+```python
+platform_env_map = {
+    ...
+    Platform.YOUR_PLATFORM: "YOUR_PLATFORM_ALLOWED_USERS",
+}
+platform_allow_all_map = {
+    ...
+    Platform.YOUR_PLATFORM: "YOUR_PLATFORM_ALLOW_ALL_USERS",
+}
+```
+
+---
+
+## 5. Session Source (`gateway/session.py`)
+
+If your platform needs extra identity fields (e.g., Signal's UUID alongside
+phone number), add them to the `SessionSource` dataclass with `Optional` defaults,
+and update `to_dict()`, `from_dict()`, and `build_source()` in base.py.
+
+---
+
+## 6. System Prompt Hints (`agent/prompt_builder.py`)
+
+Add a `PLATFORM_HINTS` entry so the agent knows what platform it's on:
+
+```python
+PLATFORM_HINTS = {
+    ...
+    "your_platform": (
+        "You are on Your Platform. "
+        "Describe formatting capabilities, media support, etc."
+    ),
+}
+```
+
+Without this, the agent won't know it's on your platform and may use
+inappropriate formatting (e.g., markdown on platforms that don't render it).
+
+---
+
+## 7. Toolset (`toolsets.py`)
+
+Add a named toolset for your platform:
+
+```python
+"hermes-your-platform": {
+    "description": "Your Platform bot toolset",
+    "tools": _HERMES_CORE_TOOLS,
+    "includes": []
+},
+```
+
+And add it to the `hermes-gateway` composite:
+
+```python
+"hermes-gateway": {
+    "includes": [..., "hermes-your-platform"]
+}
+```
+
+---
+
+## 8. Cron Delivery (`cron/scheduler.py`)
+
+Add to `platform_map` in `_deliver_result()`:
+
+```python
+platform_map = {
+    ...
+    "your_platform": Platform.YOUR_PLATFORM,
+}
+```
+
+Without this, `schedule_cronjob(deliver="your_platform")` silently fails.
+
+---
+
+## 9. Send Message Tool (`tools/send_message_tool.py`)
+
+Add to `platform_map` in `send_message_tool()`:
+
+```python
+platform_map = {
+    ...
+    "your_platform": Platform.YOUR_PLATFORM,
+}
+```
+
+Add routing in `_send_to_platform()`:
+
+```python
+elif platform == Platform.YOUR_PLATFORM:
+    return await _send_your_platform(pconfig, chat_id, message)
+```
+
+Implement `_send_your_platform()` — a standalone async function that sends
+a single message without requiring the full adapter (for use by cron jobs
+and the send_message tool outside the gateway process).
+
+Update the tool schema `target` description to include your platform example.
+
+---
+
+## 10. Cronjob Tool Schema (`tools/cronjob_tools.py`)
+
+Update the `deliver` parameter description and docstring to mention your
+platform as a delivery option.
+
+---
+
+## 11. Channel Directory (`gateway/channel_directory.py`)
+
+If your platform can't enumerate chats (most can't), add it to the
+session-based discovery list:
+
+```python
+for plat_name in ("telegram", "whatsapp", "signal", "your_platform"):
+```
+
+---
+
+## 12. Status Display (`hermes_cli/status.py`)
+
+Add to the `platforms` dict in the Messaging Platforms section:
+
+```python
+platforms = {
+    ...
+    "Your Platform": ("YOUR_PLATFORM_TOKEN", "YOUR_PLATFORM_HOME_CHANNEL"),
+}
+```
+
+---
+
+## 13. Gateway Setup Wizard (`hermes_cli/gateway.py`)
+
+Add to the `_PLATFORMS` list:
+
+```python
+{
+    "key": "your_platform",
+    "label": "Your Platform",
+    "emoji": "📱",
+    "token_var": "YOUR_PLATFORM_TOKEN",
+    "setup_instructions": [...],
+    "vars": [...],
+}
+```
+
+If your platform needs custom setup logic (connectivity testing, QR codes,
+policy choices), add a `_setup_your_platform()` function and route to it
+in the platform selection switch.
+
+Update `_platform_status()` if your platform's "configured" check differs
+from the standard `bool(get_env_value(token_var))`.
+
+---
+
+## 14. Phone/ID Redaction (`agent/redact.py`)
+
+If your platform uses sensitive identifiers (phone numbers, etc.), add a
+regex pattern and redaction function to `agent/redact.py`. This ensures
+identifiers are masked in ALL log output, not just your adapter's logs.
+
+---
+
+## 15. Documentation
+
+| File | What to update |
+|------|---------------|
+| `README.md` | Platform list in feature table + documentation table |
+| `AGENTS.md` | Gateway description + env var config section |
+| `website/docs/user-guide/messaging/<platform>.md` | **NEW** — Full setup guide (see existing platform docs for template) |
+| `website/docs/user-guide/messaging/index.md` | Architecture diagram, toolset table, security examples, Next Steps links |
+| `website/docs/reference/environment-variables.md` | All env vars for the platform |
+
+---
+
+## 16. Tests (`tests/gateway/test_<platform>.py`)
+
+Recommended test coverage:
+
+- Platform enum exists with correct value
+- Config loading from env vars via `_apply_env_overrides`
+- Adapter init (config parsing, allowlist handling, default values)
+- Helper functions (redaction, parsing, file type detection)
+- Session source round-trip (to_dict → from_dict)
+- Authorization integration (platform in allowlist maps)
+- Send message tool routing (platform in platform_map)
+
+Optional but valuable:
+- Async tests for message handling flow (mock the platform API)
+- SSE/WebSocket reconnection logic
+- Attachment processing
+- Group message filtering
+
+---
+
+## Quick Verification
+
+After implementing everything, verify with:
+
+```bash
+# All checks pass (lint + test)
+make check
+
+# Grep for your platform name to find any missed integration points
+grep -r "telegram\|discord\|whatsapp\|slack" gateway/ tools/ agent/ cron/ hermes_cli/ toolsets.py \
+  --include="*.py" -l | sort -u
+# Check each file in the output — if it mentions other platforms but not yours, you missed it
+```
