feat: filesystem checkpoints and /rollback command

Automatic filesystem snapshots before destructive file operations,
with user-facing rollback.  Inspired by PR #559 (by @alireza78a).

Architecture:
- Shadow git repos at ~/.hermes/checkpoints/{hash}/ via GIT_DIR
- CheckpointManager: take/list/restore, turn-scoped dedup, pruning
- Transparent — the LLM never sees it, no tool schema, no tokens
- Once per turn — only first write_file/patch triggers a snapshot

Integration:
- Config: checkpoints.enabled + checkpoints.max_snapshots
- CLI flag: hermes --checkpoints
- Trigger: run_agent.py _execute_tool_calls() before write_file/patch
- /rollback slash command in CLI + gateway (list, restore by number)
- Pre-rollback snapshot auto-created on restore (undo the undo)

Safety:
- Never blocks file operations — all errors silently logged
- Skips root dir, home dir, dirs >50K files
- Disables gracefully when git not installed
- Shadow repo completely isolated from project git

Tests: 35 new tests, all passing (2798 total suite)

+"""Hermes CLI skin/theme engine.
+
+A data-driven skin system that lets users customize the CLI's visual appearance.
+Skins are defined as YAML files in ~/.hermes/skins/ or as built-in presets.
+
+Each skin defines:
+- colors: banner and UI color palette (hex values for Rich markup)
+- spinner: kawaii faces, thinking verbs, optional wings
+- branding: agent name, welcome/goodbye messages, prompt symbol
+- tool_prefix: character used for tool output lines (default: ┊)
+
+Usage:
+    from hermes_cli.skin_engine import get_active_skin, list_skins, set_active_skin
+
+    skin = get_active_skin()
+    print(skin.colors["banner_title"])  # "#FFD700"

+# OpenClaw -> Hermes Migration
+
+Use this skill when a user wants to move their OpenClaw setup into Hermes Agent with minimal manual cleanup.
+
+## What this skill does
+
+It uses `scripts/openclaw_to_hermes.py` to:
+
+- import `SOUL.md` into the Hermes home directory as `SOUL.md`
+- transform OpenClaw `MEMORY.md` and `USER.md` into Hermes memory entries
+- merge OpenClaw command approval patterns into Hermes `command_allowlist`
+- migrate Hermes-compatible messaging settings such as `TELEGRAM_ALLOWED_USERS` and `MESSAGING_CWD`
+- copy OpenClaw skills into `~/.hermes/skills/openclaw-imports/`
+- optionally copy the OpenClaw workspace instructions file into a chosen Hermes workspace
+- mirror compatible workspace assets such as `workspace/tts/` into `~/.hermes/tts/`
+- archive non-secret docs that do not have a direct Hermes destination
+- produce a structured report listing migrated items, conflicts, skipped items, and reasons
+
+## Path resolution
+
+The helper script lives in this skill directory at:
+
+- `scripts/openclaw_to_hermes.py`
+
+When this skill is installed from the Skills Hub, the normal location is:
+
+- `~/.hermes/skills/migration/openclaw-migration/scripts/openclaw_to_hermes.py`
+
+Do not guess a shorter path like `~/.hermes/skills/openclaw-migration/...`.
+
+Before running the helper:
+
+1. Prefer the installed path under `~/.hermes/skills/migration/openclaw-migration/`.
+2. If that path fails, inspect the installed skill directory and resolve the script relative to the installed `SKILL.md`.
+3. Only use `find` as a fallback if the installed location is missing or the skill was moved manually.
+4. When calling the terminal tool, do not pass `workdir: "~"`. Use an absolute directory such as the user's home directory, or omit `workdir` entirely.
+
+With `--migrate-secrets`, it will also import a small allowlisted set of Hermes-compatible secrets, currently:
+
+- `TELEGRAM_BOT_TOKEN`
+
+## Default workflow
+
+1. Inspect first with a dry run.
+2. Present a simple summary of what can be migrated, what cannot be migrated, and what would be archived.
+3. If the `clarify` tool is available, use it for user decisions instead of asking for a free-form prose reply.
+4. If the dry run finds imported skill directory conflicts, ask how those should be handled before executing.
+5. Ask the user to choose between the two supported migration modes before executing.
+6. Ask for a target workspace path only if the user wants the workspace instructions file brought over.
+7. Execute the migration with the matching preset and flags.
+8. Summarize the results, especially:
+   - what was migrated
+   - what was archived for manual review
+   - what was skipped and why
+
+## User interaction protocol
+
+Hermes CLI supports the `clarify` tool for interactive prompts, but it is limited to:
+
+- one choice at a time
+- up to 4 predefined choices
+- an automatic `Other` free-text option
+
+It does **not** support true multi-select checkboxes in a single prompt.
+
+For every `clarify` call:
+
+- always include a non-empty `question`
+- include `choices` only for real selectable prompts
+- keep `choices` to 2-4 plain string options
+- never emit placeholder or truncated options such as `...`
+- never pad or stylize choices with extra whitespace
+- never include fake form fields in the question such as `enter directory here`, blank lines to fill in, or underscores like `_____`
+- for open-ended path questions, ask only the plain sentence; the user types in the normal CLI prompt below the panel
+
+If a `clarify` call returns an error, inspect the error text, correct the payload, and retry once with a valid `question` and clean choices.
+
+When `clarify` is available and the dry run reveals any required user decision, your **next action must be a `clarify` tool call**.
+Do not end the turn with a normal assistant message such as:
+
+- "Let me present the choices"
+- "What would you like to do?"
+- "Here are the options"
+
+If a user decision is required, collect it via `clarify` before producing more prose.
+If multiple unresolved decisions remain, do not insert an explanatory assistant message between them. After one `clarify` response is received, your next action should usually be the next required `clarify` call.
+
+Treat `workspace-agents` as an unresolved decision whenever the dry run reports:
+
+- `kind="workspace-agents"`
+- `status="skipped"`
+- reason containing `No workspace target was provided`
+
+In that case, you must ask about workspace instructions before execution. Do not silently treat that as a decision to skip.
+
+Because of that limitation, use this simplified decision flow:
+
+1. For `SOUL.md` conflicts, use `clarify` with choices such as:
+   - `keep existing`
+   - `overwrite with backup`
+   - `review first`
+2. If the dry run shows one or more `kind="skill"` items with `status="conflict"`, use `clarify` with choices such as:
+   - `keep existing skills`
+   - `overwrite conflicting skills with backup`
+   - `import conflicting skills under renamed folders`
+3. For workspace instructions, use `clarify` with choices such as:
+   - `skip workspace instructions`
+   - `copy to a workspace path`
+   - `decide later`
+4. If the user chooses to copy workspace instructions, ask a follow-up open-ended `clarify` question requesting an **absolute path**.
+5. If the user chooses `skip workspace instructions` or `decide later`, proceed without `--workspace-target`.
+5. For migration mode, use `clarify` with these 3 choices:
+   - `user-data only`
+   - `full compatible migration`
+   - `cancel`
+6. `user-data only` means: migrate user data and compatible config, but do **not** import allowlisted secrets.
+7. `full compatible migration` means: migrate the same compatible user data plus the allowlisted secrets when present.
+8. If `clarify` is not available, ask the same question in normal text, but still constrain the answer to `user-data only`, `full compatible migration`, or `cancel`.
+
+Execution gate:
+
+- Do not execute while a `workspace-agents` skip caused by `No workspace target was provided` remains unresolved.
+- The only valid ways to resolve it are:
+  - user explicitly chooses `skip workspace instructions`
+  - user explicitly chooses `decide later`
+  - user provides a workspace path after choosing `copy to a workspace path`
+- Absence of a workspace target in the dry run is not itself permission to execute.
+- Do not execute while any required `clarify` decision remains unresolved.
+
+Use these exact `clarify` payload shapes as the default pattern:
+
+- `{"question":"Your existing SOUL.md conflicts with the imported one. What should I do?","choices":["keep existing","overwrite with backup","review first"]}`
+- `{"question":"One or more imported OpenClaw skills already exist in Hermes. How should I handle those skill conflicts?","choices":["keep existing skills","overwrite conflicting skills with backup","import conflicting skills under renamed folders"]}`
+- `{"question":"Choose migration mode: migrate only user data, or run the full compatible migration including allowlisted secrets?","choices":["user-data only","full compatible migration","cancel"]}`
+- `{"question":"Do you want to copy the OpenClaw workspace instructions file into a Hermes workspace?","choices":["skip workspace instructions","copy to a workspace path","decide later"]}`
+- `{"question":"Please provide an absolute path where the workspace instructions should be copied."}`
+
+## Decision-to-command mapping
+
+Map user decisions to command flags exactly:
+
+- If the user chooses `keep existing` for `SOUL.md`, do **not** add `--overwrite`.
+- If the user chooses `overwrite with backup`, add `--overwrite`.
+- If the user chooses `review first`, stop before execution and review the relevant files.
+- If the user chooses `keep existing skills`, add `--skill-conflict skip`.
+- If the user chooses `overwrite conflicting skills with backup`, add `--skill-conflict overwrite`.
+- If the user chooses `import conflicting skills under renamed folders`, add `--skill-conflict rename`.
+- If the user chooses `user-data only`, execute with `--preset user-data` and do **not** add `--migrate-secrets`.
+- If the user chooses `full compatible migration`, execute with `--preset full --migrate-secrets`.
+- Only add `--workspace-target` if the user explicitly provided an absolute workspace path.
+- If the user chooses `skip workspace instructions` or `decide later`, do not add `--workspace-target`.
+
+Before executing, restate the exact command plan in plain language and make sure it matches the user's choices.
+
+## Post-run reporting rules
+
+After execution, treat the script's JSON output as the source of truth.
+
+1. Base all counts on `report.summary`.
+2. Only list an item under "Successfully Migrated" if its `status` is exactly `migrated`.
+3. Do not claim a conflict was resolved unless the report shows that item as `migrated`.
+4. Do not say `SOUL.md` was overwritten unless the report item for `kind="soul"` has `status="migrated"`.
+5. If `report.summary.conflict > 0`, include a conflict section instead of silently implying success.
+6. If counts and listed items disagree, fix the list to match the report before responding.
+7. Include the `output_dir` path from the report when available so the user can inspect `report.json`, `summary.md`, backups, and archived files.
+8. For memory or user-profile overflow, do not say the entries were archived unless the report explicitly shows an archive path. If `details.overflow_file` exists, say the full overflow list was exported there.
+9. If a skill was imported under a renamed folder, report the final destination and mention `details.renamed_from`.
+10. If `report.skill_conflict_mode` is present, use it as the source of truth for the selected imported-skill conflict policy.
+11. If an item has `status="skipped"`, do not describe it as overwritten, backed up, migrated, or resolved.
+12. If `kind="soul"` has `status="skipped"` with reason `Target already matches source`, say it was left unchanged and do not mention a backup.
+13. If a renamed imported skill has an empty `details.backup`, do not imply the existing Hermes skill was renamed or backed up. Say only that the imported copy was placed in the new destination and reference `details.renamed_from` as the pre-existing folder that remained in place.
+
+## Migration presets
+
+Prefer these two presets in normal use:
+
+- `user-data`
+- `full`
+
+`user-data` includes:
+
+- `soul`
+- `workspace-agents`
+- `memory`
+- `user-profile`
+- `messaging-settings`
+- `command-allowlist`
+- `skills`
+- `tts-assets`
+- `archive`
+
+`full` includes everything in `user-data` plus:
+
+- `secret-settings`
+
+The helper script still supports category-level `--include` / `--exclude`, but treat that as an advanced fallback rather than the default UX.
+
+## Commands
+
+Dry run with full discovery:
+
+```bash
+python3 ~/.hermes/skills/migration/openclaw-migration/scripts/openclaw_to_hermes.py
+```
+
+When using the terminal tool, prefer an absolute invocation pattern such as:
+
+```json
+{"command":"python3 /home/USER/.hermes/skills/migration/openclaw-migration/scripts/openclaw_to_hermes.py","workdir":"/home/USER"}
+```
+
+Dry run with the user-data preset:
+
+```bash
+python3 ~/.hermes/skills/migration/openclaw-migration/scripts/openclaw_to_hermes.py --preset user-data
+```
+
+Execute a user-data migration:
+
+```bash
+python3 ~/.hermes/skills/migration/openclaw-migration/scripts/openclaw_to_hermes.py --execute --preset user-data --skill-conflict skip
+```
+
+Execute a full compatible migration:
+
+```bash
+python3 ~/.hermes/skills/migration/openclaw-migration/scripts/openclaw_to_hermes.py --execute --preset full --migrate-secrets --skill-conflict skip
+```
+
+Execute with workspace instructions included:
+
+```bash
+python3 ~/.hermes/skills/migration/openclaw-migration/scripts/openclaw_to_hermes.py --execute --preset user-data --skill-conflict rename --workspace-target "/absolute/workspace/path"
+```
+
+Do not use `$PWD` or the home directory as the workspace target by default. Ask for an explicit workspace path first.
+
+## Important rules
+
+1. Run a dry run before writing unless the user explicitly says to proceed immediately.
+2. Do not migrate secrets by default. Tokens, auth blobs, device credentials, and raw gateway config should stay out of Hermes unless the user explicitly asks for secret migration.
+3. Do not silently overwrite non-empty Hermes targets unless the user explicitly wants that. The helper script will preserve backups when overwriting is enabled.
+4. Always give the user the skipped-items report. That report is part of the migration, not an optional extra.
+5. Prefer the primary OpenClaw workspace (`~/.openclaw/workspace/`) over `workspace.default/`. Only use the default workspace as fallback when the primary files are missing.
+6. Even in secret-migration mode, only migrate secrets with a clean Hermes destination. Unsupported auth blobs must still be reported as skipped.
+7. If the dry run shows a large asset copy, a conflicting `SOUL.md`, or overflowed memory entries, call those out separately before execution.
+8. Default to `user-data only` if the user is unsure.
+9. Only include `workspace-agents` when the user has explicitly provided a destination workspace path.
+10. Treat category-level `--include` / `--exclude` as an advanced escape hatch, not the normal flow.
+11. Do not end the dry-run summary with a vague “What would you like to do?” if `clarify` is available. Use structured follow-up prompts instead.
+12. Do not use an open-ended `clarify` prompt when a real choice prompt would work. Prefer selectable choices first, then free text only for absolute paths or file review requests.
+13. After a dry run, never stop after summarizing if there is still an unresolved decision. Use `clarify` immediately for the highest-priority blocking decision.
+14. Priority order for follow-up questions:
+    - `SOUL.md` conflict
+    - imported skill conflicts
+    - migration mode
+    - workspace instructions destination
+15. Do not promise to present choices later in the same message. Present them by actually calling `clarify`.
+16. After the migration-mode answer, explicitly check whether `workspace-agents` is still unresolved. If it is, your next action must be the workspace-instructions `clarify` call.
+17. After any `clarify` answer, if another required decision remains, do not narrate what was just decided. Ask the next required question immediately.
+
+## Expected result
+
+After a successful run, the user should have:
+
+- Hermes persona state imported
+- Hermes memory files populated with converted OpenClaw knowledge
+- OpenClaw skills available under `~/.hermes/skills/openclaw-imports/`
+- a migration report showing any conflicts, omissions, or unsupported data

+description: Play Pokemon games autonomously via headless emulation. Starts a game server, reads structured game state from RAM, makes strategic decisions, and sends button inputs — all from the terminal.

+---
+# Pokemon Player
+
+Play Pokemon games via headless emulation using the `pokemon-agent` package.
+
+## When to Use
+- User says "play pokemon", "start pokemon", "pokemon game"
+- User asks about Pokemon Red, Blue, Yellow, FireRed, etc.
+- User wants to watch an AI play Pokemon
+- User references a ROM file (.gb, .gbc, .gba)
+
+## Startup Procedure
+
+### 1. First-time setup (clone, venv, install)
+The repo is NousResearch/pokemon-agent on GitHub. Clone it, then
+set up a Python 3.10+ virtual environment. Use uv (preferred for speed)
+to create the venv and install the package in editable mode with the
+pyboy extra. If uv is not available, fall back to python3 -m venv + pip.
+
+On this machine it is already set up at /home/teknium/pokemon-agent
+with a venv ready — just cd there and source .venv/bin/activate.
+
+You also need a ROM file. Ask the user for theirs. On this machine
+one exists at roms/pokemon_red.gb inside that directory.
+NEVER download or provide ROM files — always ask the user.
+
+### 2. Start the game server
+From inside the pokemon-agent directory with the venv activated, run
+pokemon-agent serve with --rom pointing to the ROM and --port 9876.
+Run it in the background with &.
+To resume from a saved game, add --load-state with the save name.
+Wait 4 seconds for startup, then verify with GET /health.
+
+### 3. Set up live dashboard for user to watch
+Use an SSH reverse tunnel via localhost.run so the user can view
+the dashboard in their browser. Connect with ssh, forwarding local
+port 9876 to remote port 80 on nokey@localhost.run. Redirect output
+to a log file, wait 10 seconds, then grep the log for the .lhr.life
+URL. Give the user the URL with /dashboard/ appended.
+The tunnel URL changes each time — give the user the new one if restarted.
+
+## Save and Load
+
+### When to save
+- Every 15-20 turns of gameplay
+- ALWAYS before gym battles, rival encounters, or risky fights
+- Before entering a new town or dungeon
+- Before any action you are unsure about
+
+### How to save
+POST /save with a descriptive name. Good examples:
+before_brock, route1_start, mt_moon_entrance, got_cut
+
+### How to load
+POST /load with the save name.
+
+### List available saves
+GET /saves returns all saved states.
+
+### Loading on server startup
+Use --load-state flag when starting the server to auto-load a save.
+This is faster than loading via the API after startup.
+
+## The Gameplay Loop
+
+### Step 1: OBSERVE — check state AND take a screenshot
+GET /state for position, HP, battle, dialog.
+GET /screenshot and save to /tmp/pokemon.png, then use vision_analyze.
+Always do BOTH — RAM state gives numbers, vision gives spatial awareness.
+
+### Step 2: ORIENT
+- Dialog/text on screen → advance it
+- In battle → fight or run
+- Party hurt → head to Pokemon Center
+- Near objective → navigate carefully
+
+### Step 3: DECIDE
+Priority: dialog > battle > heal > story objective > training > explore
+
+### Step 4: ACT — move 2-4 steps max, then re-check
+POST /action with a SHORT action list (2-4 actions, not 10-15).
+
+### Step 5: VERIFY — screenshot after every move sequence
+Take a screenshot and use vision_analyze to confirm you moved where
+intended. This is the MOST IMPORTANT step. Without vision you WILL get lost.
+
+### Step 6: RECORD progress to memory with PKM: prefix
+
+### Step 7: SAVE periodically
+
+## Action Reference
+- press_a — confirm, talk, select
+- press_b — cancel, close menu
+- press_start — open game menu
+- walk_up/down/left/right — move one tile
+- hold_b_N — hold B for N frames (use for speeding through text)
+- wait_60 — wait about 1 second (60 frames)
+- a_until_dialog_end — press A repeatedly until dialog clears
+
+## Critical Tips from Experience
+
+### USE VISION CONSTANTLY
+- Take a screenshot every 2-4 movement steps
+- The RAM state tells you position and HP but NOT what is around you
+- Ledges, fences, signs, building doors, NPCs — only visible via screenshot
+- Ask the vision model specific questions: "what is one tile north of me?"
+- When stuck, always screenshot before trying random directions
+
+### Warp Transitions Need Extra Wait Time
+When walking through a door or stairs, the screen fades to black during
+the map transition. You MUST wait for it to complete. Add 2-3 wait_60
+actions after any door/stair warp. Without waiting, the position reads
+as stale and you will think you are still in the old map.
+
+### Building Exit Trap
+When you exit a building, you appear directly IN FRONT of the door.
+If you walk north, you go right back inside. ALWAYS sidestep first
+by walking left or right 2 tiles, then proceed in your intended direction.
+
+### Dialog Handling
+Gen 1 text scrolls slowly letter-by-letter. To speed through dialog,
+hold B for 120 frames then press A. Repeat as needed. Holding B makes
+text display at max speed. Then press A to advance to the next line.
+The a_until_dialog_end action checks the RAM dialog flag, but this flag
+does not catch ALL text states. If dialog seems stuck, use the manual
+hold_b + press_a pattern instead and verify via screenshot.
+
+### Ledges Are One-Way
+Ledges (small cliff edges) can only be jumped DOWN (south), never climbed
+UP (north). If blocked by a ledge going north, you must go left or right
+to find the gap around it. Use vision to identify which direction the
+gap is. Ask the vision model explicitly.
+
+### Navigation Strategy
+- Move 2-4 steps at a time, then screenshot to check position
+- When entering a new area, screenshot immediately to orient
+- Ask the vision model "which direction to [destination]?"
+- If stuck for 3+ attempts, screenshot and re-evaluate completely
+- Do not spam 10-15 movements — you will overshoot or get stuck
+
+### Running from Wild Battles
+On the battle menu, RUN is bottom-right. To reach it from the default
+cursor position (FIGHT, top-left): press down then right to move cursor
+to RUN, then press A. Wrap with hold_b to speed through text/animations.
+
+### Battling (FIGHT)
+On the battle menu FIGHT is top-left (default cursor position).
+Press A to enter move selection, A again to use the first move.
+Then hold B to speed through attack animations and text.
+
+## Battle Strategy
+
+### Decision Tree
+1. Want to catch? → Weaken then throw Poke Ball
+2. Wild you don't need? → RUN
+3. Type advantage? → Use super-effective move
+4. No advantage? → Use strongest STAB move
+5. Low HP? → Switch or use Potion
+
+### Gen 1 Type Chart (key matchups)
+- Water beats Fire, Ground, Rock
+- Fire beats Grass, Bug, Ice
+- Grass beats Water, Ground, Rock
+- Electric beats Water, Flying
+- Ground beats Fire, Electric, Rock, Poison
+- Psychic beats Fighting, Poison (dominant in Gen 1!)
+
+### Gen 1 Quirks
+- Special stat = both offense AND defense for special moves
+- Psychic type is overpowered (Ghost moves bugged)
+- Critical hits based on Speed stat
+- Wrap/Bind prevent opponent from acting
+- Focus Energy bug: REDUCES crit rate instead of raising it
+
+## Memory Conventions
+| Prefix | Purpose | Example |
+|--------|---------|---------|
+| PKM:OBJECTIVE | Current goal | Get Parcel from Viridian Mart |
+| PKM:MAP | Navigation knowledge | Viridian: mart is northeast |
+| PKM:STRATEGY | Battle/team plans | Need Grass type before Misty |
+| PKM:PROGRESS | Milestone tracker | Beat rival, heading to Viridian |
+| PKM:STUCK | Stuck situations | Ledge at y=28 go right to bypass |
+| PKM:TEAM | Team notes | Squirtle Lv6, Tackle + Tail Whip |
+
+## Progression Milestones
+- Choose starter
+- Deliver Parcel from Viridian Mart, receive Pokedex
+- Boulder Badge — Brock (Rock) → use Water/Grass
+- Cascade Badge — Misty (Water) → use Grass/Electric
+- Thunder Badge — Lt. Surge (Electric) → use Ground
+- Rainbow Badge — Erika (Grass) → use Fire/Ice/Flying
+- Soul Badge — Koga (Poison) → use Ground/Psychic
+- Marsh Badge — Sabrina (Psychic) → hardest gym
+- Volcano Badge — Blaine (Fire) → use Water/Ground
+- Earth Badge — Giovanni (Ground) → use Water/Grass/Ice
+- Elite Four → Champion!
+
+## Stopping Play
+1. Save the game with a descriptive name via POST /save
+2. Update memory with PKM:PROGRESS
+3. Tell user: "Game saved as [name]! Say 'play pokemon' to resume."
+4. Kill the server and tunnel background processes
+
+## Pitfalls
+- NEVER download or provide ROM files
+- Do NOT send more than 4-5 actions without checking vision
+- Always sidestep after exiting buildings before going north
+- Always add wait_60 x2-3 after door/stair warps
+- Dialog detection via RAM is unreliable — verify with screenshots
+- Save BEFORE risky encounters
+- The tunnel URL changes each time you restart it

+# Hermes Agent Atropos Environments
+
+Guide for building RL environments in the hermes-agent repo that integrate with the Atropos training framework.
+
+## Architecture Overview
+
+```
+Atropos BaseEnv (atroposlib/envs/base.py)
+    └── HermesAgentBaseEnv (environments/hermes_base_env.py)
+            ├── Handles agent loop orchestration
+            ├── Handles tool resolution per group
+            ├── Handles ToolContext for reward verification
+            └── YOUR ENVIRONMENT (environments/your_env.py)
+                    Only implements: setup, get_next_item, format_prompt,
+                                    compute_reward, evaluate, wandb_log
+```
+
+Hermes environments are special because they run a **multi-turn agent loop with tool calling** — not just single-turn completions. The base env handles the loop; you implement the task and scoring.
+
+## File Locations
+
+| File | Purpose |
+|------|---------|
+| `environments/hermes_base_env.py` | Base class with agent loop + tool resolution |
+| `environments/agent_loop.py` | `HermesAgentLoop` + `AgentResult` dataclass |
+| `environments/tool_context.py` | `ToolContext` for reward verification |
+| `environments/tool_call_parsers.py` | Phase 2 tool call parsers (hermes, mistral, etc.) |
+| `environments/your_env.py` | Your environment implementation |
+
+## Inference Setup — Ask the User First
+
+**IMPORTANT:** Before running any test, evaluation, or data generation command, always ask the user how they want to handle inference. Do NOT assume OpenRouter or any specific endpoint. Present these options:
+
+1. **OpenRouter** — Ask which model they want to use (e.g., `anthropic/claude-sonnet-4.5`, `google/gemini-2.5-pro`, `meta-llama/llama-3.3-70b-instruct`, etc.). Requires `OPENROUTER_API_KEY` in environment.
+2. **Self-hosted VLLM endpoint** — Ask for their base URL (e.g., `http://localhost:8000/v1`) and model name. Set `--openai.server_type vllm`.
+3. **Other OpenAI-compatible API** — Ask for the base URL, model name, and any required API key. Set `--openai.server_type openai` and `--openai.health_check false`.
+4. **Local Atropos training server** — For `serve` mode with a live training loop. Default `http://localhost:8000/v1`.
+
+Once the user tells you their setup, use those values in all CLI commands for that session. Example prompts:
+
+> "Before I run this, how would you like to handle inference?
+> 1. OpenRouter (I'll need your preferred model, e.g. claude-sonnet-4.5)
+> 2. A self-hosted VLLM endpoint (give me the URL and model name)
+> 3. Another OpenAI-compatible API (give me the URL, model, and any auth details)
+> 4. Local Atropos training server (serve mode)"
+
+### Key flags by provider:
+
+| Provider | `--openai.server_type` | `--openai.health_check` | `--openai.api_key` |
+|----------|----------------------|------------------------|-------------------|
+| OpenRouter | `openai` | `false` | `$OPENROUTER_API_KEY` |
+| VLLM (self-hosted) | `vllm` | (default) | (not needed) |
+| Other OpenAI-compatible | `openai` | `false` | As needed |
+| Local Atropos | (default) | (default) | (not needed) |
+
+## Required Methods
+
+### 1. `setup()` — Load dataset and initialize state
+
+```python
+async def setup(self) -> None:
+    """Called once at startup. Load datasets, initialize state."""
+    # Try HuggingFace first, fallback to built-in samples
+    try:
+        from datasets import load_dataset
+        ds = load_dataset("your/dataset", split="test")
+        self._items = [...]
+    except Exception:
+        self._items = BUILTIN_SAMPLES
+
+    # Always split into train/eval
+    random.shuffle(self._items)
+    eval_size = max(20, int(len(self._items) * 0.1))
+    self._eval_items = self._items[:eval_size]
+    self._items = self._items[eval_size:]
+```
+
+### 2. `get_next_item()` — Return next training item
+
+```python
+async def get_next_item(self) -> dict:
+    """Return next item, cycling through dataset."""
+    item = self._items[self._index % len(self._items)]
+    self._index += 1
+    return item
+```
+
+### 3. `format_prompt(item)` — Convert item to user message
+
+```python
+def format_prompt(self, item: dict) -> str:
+    """Convert a dataset item into the user-facing prompt."""
+    return f"Research this question: {item['question']}"
+```
+
+### 4. `compute_reward(item, result, ctx)` — Score the rollout
+
+**CRITICAL**: `result` is an `AgentResult`, NOT a dict. It has these attributes:
+- `result.messages` — List of message dicts (OpenAI format)
+- `result.turns_used` — Number of LLM calls made
+- `result.finished_naturally` — True if model stopped voluntarily
+- `result.tool_errors` — List of ToolError objects
+
+**AgentResult does NOT have**: `final_response`, `tool_calls`, `tools_used`.
+You must extract these from `result.messages`:
+
+```python
+async def compute_reward(self, item, result: AgentResult, ctx: ToolContext) -> float:
+    # Extract final response (last assistant message with content)
+    final_response = ""
+    tools_used = []
+    for msg in reversed(result.messages):
+        if msg.get("role") == "assistant" and msg.get("content") and not final_response:
+            final_response = msg["content"]
+        if msg.get("role") == "assistant" and msg.get("tool_calls"):
+            for tc in msg["tool_calls"]:
+                fn = tc.get("function", {}) if isinstance(tc, dict) else {}
+                name = fn.get("name", "")
+                if name:
+                    tools_used.append(name)
+
+    # Score using LLM judge, heuristic, or ToolContext verification
+    correctness = await self._llm_judge(item, final_response)
+    return correctness
+```
+
+`ctx` (ToolContext) gives you terminal/file access to the agent's sandbox for verification:
+```python
+# Run tests in the agent's sandbox
+result = ctx.terminal("pytest /workspace/test.py")
+return 1.0 if result["exit_code"] == 0 else 0.0
+```
+
+### 5. `evaluate()` — Periodic evaluation with full agent loop
+
+**MUST use the full agent loop with tools**, not single-turn chat_completion.
+The whole point of hermes-agent environments is agentic evaluation:
+
+```python
+async def evaluate(self, *args, **kwargs) -> None:
+    import time, uuid
+    from environments.agent_loop import HermesAgentLoop
+    from environments.tool_context import ToolContext
+
+    start_time = time.time()
+    tools, valid_names = self._resolve_tools_for_group()
+    samples = []
+
+    for item in self._eval_items[:self.config.eval_size]:
+        task_id = str(uuid.uuid4())
+        messages = []
+        if self.config.system_prompt:
+            messages.append({"role": "system", "content": self.config.system_prompt})
+        messages.append({"role": "user", "content": self.format_prompt(item)})
+
+        agent = HermesAgentLoop(
+            server=self.server,
+            tool_schemas=tools,
+            valid_tool_names=valid_names,
+            max_turns=self.config.max_agent_turns,
+            task_id=task_id,
+            temperature=0.0,  # Deterministic for eval
+            max_tokens=self.config.max_token_length,
+            extra_body=self.config.extra_body,
+        )
+        result = await agent.run(messages)
+
+        ctx = ToolContext(task_id)
+        try:
+            reward = await self.compute_reward(item, result, ctx)
+        finally:
+            ctx.cleanup()
+
+        samples.append({"prompt": ..., "response": ..., "reward": reward})
+
+    eval_metrics = {"eval/mean_reward": ...}
+    await self.evaluate_log(metrics=eval_metrics, samples=samples,
+                            start_time=start_time, end_time=time.time())
+```
+
+### 6. `wandb_log()` — Custom metrics logging
+
+Always call `super().wandb_log()` at the end:
+
+```python
+async def wandb_log(self, wandb_metrics=None):
+    if wandb_metrics is None:
+        wandb_metrics = {}
+    if self._reward_buffer:
+        n = len(self._reward_buffer)
+        wandb_metrics["train/mean_reward"] = sum(self._reward_buffer) / n
+        self._reward_buffer.clear()
+    await super().wandb_log(wandb_metrics)  # MUST call super
+```
+
+**Pitfall**: `compute_reward` appends to metric buffers. During eval, this pollutes training metrics. Roll back buffer entries added during eval.
+
+## Config Class
+
+Always create a custom config subclass with Pydantic Field descriptors. Key inherited fields you can tune: `enabled_toolsets`, `max_agent_turns`, `agent_temperature`, `system_prompt`, `terminal_backend`, `group_size`, `steps_per_eval`, `total_steps`.
+
+## config_init() — Default Configuration
+
+Classmethod returning `(YourEnvConfig, [APIServerConfig(...)])`. Set server_type to "openai" for OpenRouter/external APIs. Load API key from environment variable.
+
+## Three CLI Modes
+
+```bash
+# SERVE — Full training loop (connects to Atropos API server)
+python environments/my_env.py serve --openai.base_url http://localhost:8000/v1
+
+# PROCESS — Offline data generation (saves JSONL)
+python environments/my_env.py process --env.total_steps 10 --env.group_size 1 \
+    --env.use_wandb false --env.data_path_to_save_groups output.jsonl \
+    --openai.base_url "<USER_BASE_URL>" \
+    --openai.model_name "<USER_MODEL>" \
+    --openai.server_type <USER_SERVER_TYPE> --openai.health_check false
+
+# EVALUATE — Standalone eval (runs setup + evaluate only)
+python environments/my_env.py evaluate --env.eval_size 20 \
+    --env.data_dir_to_save_evals /tmp/eval_results \
+    --openai.base_url "<USER_BASE_URL>" \
+    --openai.model_name "<USER_MODEL>" \
+    --openai.server_type <USER_SERVER_TYPE> --openai.health_check false
+```
+
+Config priority: CLI args > YAML file > config_init() defaults.
+
+## Common Pitfalls
+
+1. **AgentResult has .messages, not .final_response** — Extract the final response by iterating reversed(result.messages) looking for the last assistant message with content.
+
+2. **evaluate() must use HermesAgentLoop, not chat_completion** — Single-turn chat_completion has no tools. The whole point of hermes-agent benchmarks is agentic evaluation with tool use.
+
+3. **Don't call _llm_judge twice** — If compute_reward already calls it, extract the score from the buffer instead of calling judge separately in evaluate().
+
+4. **Eval pollutes training buffers** — compute_reward appends to metric buffers. During eval, roll back buffer entries to keep training metrics clean.
+
+5. **Always set health_check=false for OpenRouter** — OpenRouter has no /health endpoint.
+
+6. **Set data_dir_to_save_evals in evaluate mode** — Without it, results aren't saved.
+
+7. **default_toolsets class variable vs enabled_toolsets config** — The class variable is a hint; the config field is what actually controls tool resolution.
+
+8. **Tool call parsing in messages** — Tool calls are dicts with `{"function": {"name": ..., "arguments": ...}}`. Always check `isinstance(tc, dict)`.
+
+9. **ToolContext.cleanup()** — Always call in a finally block to release sandbox resources.
+
+10. **server_type must be "openai" for external APIs** — Without it, Atropos assumes a local VLLM server.
+
+11. **Always ask the user for their inference setup** — Never hardcode or assume a specific provider/model. See the "Inference Setup" section above.
+
+## Reward Function Patterns
+
+### LLM Judge (for open-ended tasks)
+Use `self.server.chat_completion()` with a scoring prompt. Parse JSON response for score float. Always include a heuristic fallback (keyword overlap) for when the judge call fails.
+
+### Binary Verification (for code/terminal tasks)
+Use `ctx.terminal("pytest test.py -q")` to run tests in the agent's sandbox. Return 1.0 for pass, 0.0 for fail.
+
+### Multi-Signal (combine multiple indicators)
+Weight correctness (0.6) + tool usage (0.2) + efficiency (0.2) + optional bonuses. Clamp to [0, 1].
+
+## Testing Your Environment
+
+1. **Import test**: `python -c "from environments.my_env import MyEnv; print('OK')"`
+2. **Ask the user for inference setup** (see "Inference Setup" section above)
+3. **Process mode** (1 item): Verify JSONL output has valid tokens, masks, scores
+4. **Evaluate mode**: Verify full agent loop runs with tools, metrics logged correctly
+5. **Check reward range**: Scores should be in [0, 1], not all identical
+
+## Minimum Implementation Checklist
+
+```python
+class MyEnv(HermesAgentBaseEnv):
+    name = "my-env"
+    env_config_cls = MyEnvConfig
+
+    @classmethod
+    def config_init(cls): ...          # Default server + env config

+# AgentResult Fields Reference
+
+`AgentResult` is defined in `environments/agent_loop.py` as a dataclass.
+
+## Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `messages` | `List[Dict[str, Any]]` | Full conversation history in OpenAI message format |
+| `managed_state` | `Optional[Dict]` | ManagedServer.get_state() if Phase 2, else None |
+| `turns_used` | `int` | Number of LLM calls made during the loop |
+| `finished_naturally` | `bool` | True if model stopped calling tools on its own |
+| `reasoning_per_turn` | `List[Optional[str]]` | Extracted reasoning content per turn |
+| `tool_errors` | `List[ToolError]` | Tool errors encountered during the loop |
+
+## ToolError Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `turn` | `int` | Which turn the error occurred |
+| `tool_name` | `str` | Name of the tool that failed |
+| `arguments` | `str` | Arguments passed to the tool |
+| `error` | `str` | Error message |
+| `tool_result` | `str` | The result returned to the model |
+
+## Extracting Data from Messages
+
+Messages follow OpenAI format. Common patterns:
+
+```python
+# Get final assistant response
+for msg in reversed(result.messages):
+    if msg.get("role") == "assistant" and msg.get("content"):
+        final_response = msg["content"]
+        break
+
+# Get all tool names used
+tools = []
+for msg in result.messages:
+    if msg.get("role") == "assistant" and msg.get("tool_calls"):
+        for tc in msg["tool_calls"]:
+            fn = tc.get("function", {}) if isinstance(tc, dict) else {}
+            tools.append(fn.get("name", ""))
+
+# Get tool results
+for msg in result.messages:
+    if msg.get("role") == "tool":
+        tool_output = msg.get("content", "")
+        call_id = msg.get("tool_call_id", "")
+```
+
+## Fields that DO NOT EXIST
+
+These are common mistakes — AgentResult does NOT have:
+- `final_response` — extract from messages
+- `tool_calls` — extract from messages  
+- `tools_used` — extract from messages
+- `output` — extract from messages
+- `response` — extract from messages

+# Usage Patterns — Testing Environments and Evaluating Models
+
+## Pattern 1: Test Your Environment Works (process mode)
+
+Use `process` mode to verify your environment runs end-to-end before
+committing. This generates trajectories without needing an Atropos
+training server.
+
+**Before running:** Ask the user for their inference setup (see SKILL.md "Inference Setup" section). Replace `<BASE_URL>`, `<MODEL>`, and `<SERVER_TYPE>` below with their chosen values.
+
+### Step 1: Run 1 trajectory
+
+```bash
+cd ~/.hermes/hermes-agent
+source .venv/bin/activate
+
+python environments/your_env.py process \
+  --env.total_steps 1 \
+  --env.group_size 1 \
+  --env.use_wandb false \
+  --env.data_path_to_save_groups /tmp/test_output.jsonl \
+  --openai.base_url "<BASE_URL>" \
+  --openai.model_name "<MODEL>" \
+  --openai.server_type <SERVER_TYPE> \
+  --openai.health_check false
+```
+
+### Step 2: Verify the output
+
+```python
+import json
+for line in open("/tmp/test_output.jsonl"):
+    data = json.loads(line)
+    print(f"Scores: {data.get('scores', [])}")
+    print(f"Token sequences: {len(data.get('tokens', []))}")
+    # Check messages include tool calls
+    for msg_list in data.get("messages", []):
+        roles = [m.get("role") for m in msg_list]
+        print(f"Roles: {roles}")
+        for m in reversed(msg_list):
+            if m.get("role") == "assistant" and m.get("content"):
+                print(f"Response: {m['content'][:200]}...")
+                break
+```
+
+### What to check:
+- **Scores are not all 0.0** — if so, compute_reward is broken
+- **Scores are in [0, 1]** — not negative, not >1
+- **Messages include "tool" role entries** — agent used tools
+- **Token sequences are non-empty**
+- **An HTML visualization is generated** next to the .jsonl
+
+### Common failures:
+- `'AgentResult' object has no attribute 'X'` — accessing a field that doesn't exist. See agentresult-fields.md.
+- Score always 0.0 — reward function erroring silently
+- Score always 1.0 — verification too lenient or not running
+
+
+## Pattern 2: Evaluate a Model (evaluate mode)
+
+Use `evaluate` mode to benchmark a model on your environment's eval
+split. This runs the full agent loop with tools for each eval item.
+
+### Step 1: Run evaluation
+
+```bash
+python environments/your_env.py evaluate \
+  --env.eval_size 20 \
+  --env.use_wandb false \
+  --env.data_dir_to_save_evals /tmp/eval_results \
+  --openai.base_url "<BASE_URL>" \
+  --openai.model_name "<MODEL>" \
+  --openai.server_type <SERVER_TYPE> \
+  --openai.health_check false
+```
+
+### Step 2: Read results
+
+Stdout shows a lighteval-compatible table:
+
+```
+Evaluation Results: your-env_eval
+|Metric          |  Value|
+|mean correctness| 0.850 |
+|mean reward     | 0.920 |
+|mean tool calls | 4.300 |
+|n items         | 20    |
+Evaluation completed in 367 seconds
+```
+
+JSON results saved to the eval directory:
+
+```python
+import json
+data = json.load(open("/tmp/eval_results/metrics.json"))
+for metric, value in data["results"]["all"].items():
+    print(f"{metric}: {value}")
+```
+
+### Step 3: Compare models
+
+Run evaluate with different models and compare the metrics.json files.
+
+### What to check:
+- **"data_dir_to_save_evals is not set"** — you forgot the flag, results won't be saved
+- **Tool usage rate = 0** — evaluate() is using chat_completion instead of HermesAgentLoop
+- **All scores identical** — judge failing, falling back to heuristic
+- **Very slow** — each item runs a full agent loop (~30-90s). Use `--env.eval_size 5` for quick checks.
+
+
+## Pattern 3: Generate Training Data (process mode, larger scale)
+
+Generate trajectory data for offline training or analysis:
+
+```bash
+python environments/your_env.py process \
+  --env.total_steps 50 \
+  --env.group_size 4 \
+  --env.use_wandb false \
+  --env.data_path_to_save_groups data/trajectories.jsonl \
+  --openai.base_url "<BASE_URL>" \
+  --openai.model_name "<MODEL>" \
+  --openai.server_type <SERVER_TYPE> \
+  --openai.health_check false
+```
+
+### Analyze the distribution:
+
+```python
+import json
+scores = []
+for line in open("data/trajectories.jsonl"):
+    data = json.loads(line)
+    scores.extend(data.get("scores", []))
+
+print(f"Total: {len(scores)}, Mean: {sum(scores)/len(scores):.3f}")
+for bucket in [0.0, 0.2, 0.4, 0.6, 0.8, 1.0]:
+    count = sum(1 for s in scores if abs(s - bucket) < 0.1)
+    print(f"  {bucket:.1f}: {'█' * count} ({count})")
+```
+
+### What to check:
+- **Score distribution has variance** — RL needs score variance. All-same scores are useless.
+
+
+## Pattern 4: Full RL Training (serve mode)
+
+For actual RL training with Atropos:
+
+```bash
+# Terminal 1: Start Atropos API server
+run-api
+
+# Terminal 2: Start your environment
+python environments/your_env.py serve \
+  --config environments/your_env/default.yaml
+```
+
+For Phase 2 with VLLM:
+
+```bash
+# Terminal 1: VLLM server
+python -m vllm.entrypoints.openai.api_server --model your-model --port 8000
+
+# Terminal 2: Atropos API
+run-api
+
+# Terminal 3: Environment
+python environments/your_env.py serve \
+  --openai.base_url http://localhost:8000/v1 \
+  --openai.model_name your-model \
+  --openai.server_type vllm
+```
+
+
+## Pattern 5: Quick Smoke Test
+
+Verify imports and config before spending money on API calls:
+
+```python
+from environments.your_env import YourEnv
+print(f"Name: {YourEnv.name}")
+cfg, servers = YourEnv.config_init()
+print(f"Toolsets: {cfg.enabled_toolsets}")
+print(f"Server: {servers[0].model_name}")
+print("All imports OK")
+```
+
+
+## Timing Expectations
+
+| Mode | Items | Time per item | Total |
+|------|-------|--------------|-------|
+| process (1 item) | 1 | 30-90s | ~1 min |
+| evaluate (5 items) | 5 | 30-90s | ~5 min |
+| evaluate (20 items) | 20 | 30-90s | ~15-30 min |
+| process (50 items) | 50 | 30-90s | ~30-75 min |
+
+Times are for cloud APIs with Claude Sonnet-class models. Local models may be faster or slower depending on hardware.

+Checkpoint Manager — Transparent filesystem snapshots via shadow git repos.
+
+Creates automatic snapshots of working directories before file-mutating
+operations (write_file, patch), triggered once per conversation turn.
+Provides rollback to any previous checkpoint.
+
+This is NOT a tool — the LLM never sees it.  It's transparent infrastructure
+controlled by the ``checkpoints`` config flag or ``--checkpoints`` CLI flag.
+
+Architecture:
+    ~/.hermes/checkpoints/{sha256(abs_dir)[:16]}/   — shadow git repo
+        HEAD, refs/, objects/                        — standard git internals
+        HERMES_WORKDIR                               — original dir path
+        info/exclude                                 — default excludes
+
+The shadow repo uses GIT_DIR + GIT_WORK_TREE so no git state leaks
+into the user's project directory.

+# Filesystem Checkpoints
+
+Hermes can automatically snapshot your working directory before making file changes, giving you a safety net to roll back if something goes wrong.
+
+## How It Works
+
+When enabled, Hermes takes a **one-time snapshot** at the start of each conversation turn before the first file-modifying operation (`write_file` or `patch`). This creates a point-in-time backup you can restore to at any time.
+
+Under the hood, checkpoints use a **shadow git repository** stored at `~/.hermes/checkpoints/`. This is completely separate from your project's git — no `.git` directory is created in your project, and your own git history is never touched.
+
+## Enabling Checkpoints
+
+### Per-session (CLI flag)
+
+```bash
+hermes --checkpoints
+```
+
+### Permanently (config.yaml)
+
+```yaml
+# ~/.hermes/config.yaml
+checkpoints:
+  enabled: true
+  max_snapshots: 50  # max checkpoints per directory (default: 50)
+```
+
+## Rolling Back
+
+Use the `/rollback` slash command:
+
+```
+/rollback          # List all available checkpoints
+/rollback 1        # Restore to checkpoint #1 (most recent)
+/rollback 3        # Restore to checkpoint #3 (further back)
+/rollback abc1234  # Restore by git commit hash
+```
+
+Example output:
+
+```
+📸 Checkpoints for /home/user/project:
+
+  1. abc1234  2026-03-10 14:22  before write_file
+  2. def5678  2026-03-10 14:15  before patch
+  3. ghi9012  2026-03-10 14:08  before write_file
+
+Use /rollback <number> to restore, e.g. /rollback 1

+
+When you restore, Hermes automatically takes a **pre-rollback snapshot** first — so you can always undo your undo.
+
+## What Gets Checkpointed
+
+Checkpoints capture the entire working directory (the project root), excluding common large/sensitive patterns:
+
+- `node_modules/`, `dist/`, `build/`
+- `.env`, `.env.*`
+- `__pycache__/`, `*.pyc`
+- `.venv/`, `venv/`
+- `.git/`
+- `.DS_Store`, `*.log`
+
+## Performance
+
+Checkpoints are designed to be lightweight:
+
+- **Once per turn** — only the first file operation triggers a snapshot, not every write
+- **Skips large directories** — directories with >50,000 files are skipped automatically
+- **Skips when nothing changed** — if no files were modified since the last checkpoint, no commit is created
+- **Non-blocking** — if a checkpoint fails for any reason, the file operation proceeds normally
+
+## How It Determines the Project Root
+
+When you write to a file like `src/components/Button.tsx`, Hermes walks up the directory tree looking for project markers (`.git`, `pyproject.toml`, `package.json`, `Cargo.toml`, etc.) to find the project root. This ensures the entire project is checkpointed, not just the file's parent directory.
+
+## Platforms
+
+Checkpoints work on both:
+- **CLI** — uses your current working directory
+- **Gateway** (Telegram, Discord, etc.) — uses `MESSAGING_CWD`
+
+The `/rollback` command is available on all platforms.
+
+## FAQ
+
+**Does this conflict with my project's git?**
+No. Checkpoints use a completely separate shadow git repository via `GIT_DIR` environment variables. Your project's `.git/` is never touched.
+
+**How much disk space do checkpoints use?**
+Git is very efficient at storing diffs. For most projects, checkpoint data is negligible. Old checkpoints are pruned when `max_snapshots` is exceeded.
+
+**Can I checkpoint without git installed?**
+No — git must be available on your PATH. If it's not installed, checkpoints silently disable.
+
+**Can I roll back across sessions?**
+Yes! Checkpoints persist in `~/.hermes/checkpoints/` and survive across sessions. You can roll back to a checkpoint from yesterday.
