# Hermes Agent

Hermes Agent is an open-source AI agent framework by Nous Research that runs in your terminal, messaging platforms, and IDEs. It belongs to the same category as Claude Code (Anthropic), Codex (OpenAI), and OpenClaw — autonomous coding and task-execution agents that use tool calling to interact with your system. Hermes works with any LLM provider (OpenRouter, Anthropic, OpenAI, DeepSeek, local models, and 15+ others) and runs on Linux, macOS, and WSL.

What makes Hermes different:

- **Self-improving through skills** — Hermes learns from experience by saving reusable procedures as skills. When it solves a complex problem, discovers a workflow, or gets corrected, it can persist that knowledge as a skill document that loads into future sessions. Skills accumulate over time, making the agent better at your specific tasks and environment.
- **Persistent memory across sessions** — remembers who you are, your preferences, environment details, and lessons learned. Pluggable memory backends (built-in, Honcho, Mem0, and more) let you choose how memory works.
- **Multi-platform gateway** — the same agent runs on Telegram, Discord, Slack, WhatsApp, Signal, Matrix, Email, and 10+ other platforms with full tool access, not just chat.
- **Provider-agnostic** — swap models and providers mid-workflow without changing anything else. Credential pools rotate across multiple API keys automatically.
- **Profiles** — run multiple independent Hermes instances with isolated configs, sessions, skills, and memory.
- **Extensible** — plugins, MCP servers, custom tools, webhook triggers, cron scheduling, and the full Python ecosystem.

People use Hermes for software development, research, system administration, data analysis, content creation, home automation, and anything else that benefits from an AI agent with persistent context and full system access.

**This skill helps you work with Hermes Agent effectively** — setting it up, configuring features, spawning additional agent instances, troubleshooting issues, finding the right commands and settings, and understanding how the system works when you need to extend or contribute to it.

Tool changes take effect on `/reset` (new session). They do NOT apply mid-conversation to preserve prompt caching.

---

## Security & Privacy Toggles

Common "why is Hermes doing X to my output / tool calls / commands?" toggles — and the exact commands to change them. Most of these need a fresh session (`/reset` in chat, or start a new `hermes` invocation) because they're read once at startup.

### Secret redaction in tool output

Secret redaction is **on by default** — tool output (terminal stdout, `read_file`, web content, subagent summaries, etc.) is scanned for strings that look like API keys, tokens, and secrets before it enters the conversation context and logs. Leave it enabled for normal use:

```bash
hermes config set security.redact_secrets true       # keep enabled globally
```

**Restart required.** `security.redact_secrets` is snapshotted at import time — toggling it mid-session (e.g. via `export HERMES_REDACT_SECRETS=false` from a tool call) will NOT take effect for the running process. Tell the user to change it in config from a terminal, then start a new session. This is deliberate — it prevents an LLM from flipping the toggle on itself mid-task.

Disable only when you deliberately need raw credential-like strings for debugging or redactor development:
```bash
hermes config set security.redact_secrets false
```

### PII redaction in gateway messages

Separate from secret redaction. When enabled, the gateway hashes user IDs and strips phone numbers from the session context before it reaches the model:

```bash
hermes config set privacy.redact_pii true    # enable
hermes config set privacy.redact_pii false   # disable (default)
```

### Command approval prompts

By default (`approvals.mode: manual`), Hermes prompts the user before running shell commands flagged as destructive (`rm -rf`, `git reset --hard`, etc.). The modes are:

- `manual` — always prompt (default)
- `smart` — use an auxiliary LLM to auto-approve low-risk commands, prompt on high-risk
- `off` — skip all approval prompts (equivalent to `--yolo`)

```bash
hermes config set approvals.mode smart       # recommended middle ground
hermes config set approvals.mode off         # bypass everything (not recommended)
```

Per-invocation bypass without changing config:
- `hermes --yolo …`
- `export HERMES_YOLO_MODE=1`

Note: YOLO / `approvals.mode: off` does NOT turn off secret redaction. They are independent.

### Shell hooks allowlist

Some shell-hook integrations require explicit allowlisting before they fire. Managed via `~/.hermes/shell-hooks-allowlist.json` — prompted interactively the first time a hook wants to run.

### Disabling the web/browser/image-gen tools

To keep the model away from network or media tools entirely, open `hermes tools` and toggle per-platform. Takes effect on next session (`/reset`). See the Tools & Skills section above.

---

## Voice & Transcription

### STT (Voice → Text)

Voice messages from messaging platforms are auto-transcribed.

Provider priority (auto-detected):
1. **Local faster-whisper** — free, no API key: `pip install faster-whisper`
2. **Groq Whisper** — free tier: set `GROQ_API_KEY`
3. **OpenAI Whisper** — paid: set `VOICE_TOOLS_OPENAI_KEY`
4. **Mistral Voxtral** — set `MISTRAL_API_KEY`

Config:
```yaml
stt:
  enabled: true
  provider: local        # local, groq, openai, mistral
  local:
    model: base          # tiny, base, small, medium, large-v3
```

### TTS (Text → Voice)

| Provider | Env var | Free? |
|----------|---------|-------|
| Edge TTS | None | Yes (default) |
| ElevenLabs | `ELEVENLABS_API_KEY` | Free tier |
| OpenAI | `VOICE_TOOLS_OPENAI_KEY` | Paid |
| MiniMax | `MINIMAX_API_KEY` | Paid |
| Mistral (Voxtral) | `MISTRAL_API_KEY` | Paid |
| NeuTTS (local) | None (`pip install neutts[all]` + `espeak-ng`) | Free |

Voice commands: `/voice on` (voice-to-voice), `/voice tts` (always voice), `/voice off`.

## Spawning Additional Hermes Instances

Run additional Hermes processes as fully independent subprocesses — separate sessions, tools, and environments.

### When to Use This vs delegate_task

| | `delegate_task` | Spawning `hermes` process |
|-|-----------------|--------------------------|
| Isolation | Separate conversation, shared process | Fully independent process |
| Duration | Minutes (bounded by parent loop) | Hours/days |
| Tool access | Subset of parent's tools | Full tool access |
| Interactive | No | Yes (PTY mode) |
| Use case | Quick parallel subtasks | Long autonomous missions |

### One-Shot Mode

```
terminal(command="hermes chat -q 'Research GRPO papers and write summary to ~/research/grpo.md'", timeout=300)

# Background for long tasks:
terminal(command="hermes chat -q 'Set up CI/CD for ~/myapp'", background=true)
```

### Interactive PTY Mode (via tmux)

Hermes uses prompt_toolkit, which requires a real terminal. Use tmux for interactive spawning:

```
# Start
terminal(command="tmux new-session -d -s agent1 -x 120 -y 40 'hermes'", timeout=10)

# Wait for startup, then send a message
terminal(command="sleep 8 && tmux send-keys -t agent1 'Build a FastAPI auth service' Enter", timeout=15)

# Read output
terminal(command="sleep 20 && tmux capture-pane -t agent1 -p", timeout=5)

# Send follow-up
terminal(command="tmux send-keys -t agent1 'Add rate limiting middleware' Enter", timeout=5)

# Exit
terminal(command="tmux send-keys -t agent1 '/exit' Enter && sleep 2 && tmux kill-session -t agent1", timeout=10)
```

### Multi-Agent Coordination

```
# Agent A: backend
terminal(command="tmux new-session -d -s backend -x 120 -y 40 'hermes -w'", timeout=10)
terminal(command="sleep 8 && tmux send-keys -t backend 'Build REST API for user management' Enter", timeout=15)

# Agent B: frontend
terminal(command="tmux new-session -d -s frontend -x 120 -y 40 'hermes -w'", timeout=10)
terminal(command="sleep 8 && tmux send-keys -t frontend 'Build React dashboard for user management' Enter", timeout=15)

# Check progress, relay context between them
terminal(command="tmux capture-pane -t backend -p | tail -30", timeout=5)
terminal(command="tmux send-keys -t frontend 'Here is the API schema from the backend agent: ...' Enter", timeout=5)
```

### Session Resume

```
# Resume most recent session
terminal(command="tmux new-session -d -s resumed 'hermes --continue'", timeout=10)

# Resume specific session
terminal(command="tmux new-session -d -s resumed 'hermes --resume 20260225_143052_a1b2c3'", timeout=10)
```

### Tips

- **Prefer `delegate_task` for quick subtasks** — less overhead than spawning a full process
- **Use `-w` (worktree mode)** when spawning agents that edit code — prevents git conflicts
- **Set timeouts** for one-shot mode — complex tasks can take 5-10 minutes
- **Use `hermes chat -q` for fire-and-forget** — no PTY needed
- **Use tmux for interactive sessions** — raw PTY mode has `\r` vs `\n` issues with prompt_toolkit
- **For scheduled tasks**, use the `cronjob` tool instead of spawning — handles delivery and retry

---

## Durable & Background Systems

Four systems run alongside the main conversation loop. Quick reference
here; full developer notes live in `AGENTS.md`, user-facing docs under
`website/docs/user-guide/features/`.

### Delegation (`delegate_task`)

Synchronous subagent spawn — the parent waits for the child's summary
before continuing its own loop. Isolated context + terminal session.

- **Single:** `delegate_task(goal, context, toolsets)`.
- **Batch:** `delegate_task(tasks=[{goal, ...}, ...])` runs children in
  parallel, capped by `delegation.max_concurrent_children` (default 3).
- **Roles:** `leaf` (default; cannot re-delegate) vs `orchestrator`
  (can spawn its own workers, bounded by `delegation.max_spawn_depth`).
- **Not durable.** If the parent is interrupted, the child is
  cancelled. For work that must outlive the turn, use `cronjob` or
  `terminal(background=True, notify_on_complete=True)`.

Config: `delegation.*` in `config.yaml`.

### Cron (scheduled jobs)

Durable scheduler — `cron/jobs.py` + `cron/scheduler.py`. Drive it via
the `cronjob` tool, the `hermes cron` CLI (`list`, `add`, `edit`,
`pause`, `resume`, `run`, `remove`), or the `/cron` slash command.

- **Schedules:** duration (`"30m"`, `"2h"`), "every" phrase
  (`"every monday 9am"`), 5-field cron (`"0 9 * * *"`), or ISO timestamp.
- **Per-job knobs:** `skills`, `model`/`provider` override, `script`
  (pre-run data collection; `no_agent=True` makes the script the whole
  job), `context_from` (chain job A's output into job B), `workdir`
  (run in a specific dir with its `AGENTS.md` / `CLAUDE.md` loaded),
  multi-platform delivery.
- **Invariants:** 3-minute hard interrupt per run, `.tick.lock` file
  prevents duplicate ticks across processes, cron sessions pass
  `skip_memory=True` by default, and cron deliveries are framed with a
  header/footer instead of being mirrored into the target gateway
  session (keeps role alternation intact).

User docs: https://hermes-agent.nousresearch.com/docs/user-guide/features/cron

### Curator (skill lifecycle)

Background maintenance for agent-created skills. Tracks usage, marks
idle skills stale, archives stale ones, keeps a pre-run tar.gz backup
so nothing is lost.

- **CLI:** `hermes curator <verb>` — `status`, `run`, `pause`, `resume`,
  `pin`, `unpin`, `archive`, `restore`, `prune`, `backup`, `rollback`.
- **Slash:** `/curator <subcommand>` mirrors the CLI.
- **Scope:** only touches skills with `created_by: "agent"` provenance.
  Bundled + hub-installed skills are off-limits. **Never deletes** —
  max destructive action is archive. Pinned skills are exempt from
  every auto-transition and every LLM review pass.
- **Telemetry:** sidecar at `~/.hermes/skills/.usage.json` holds
  per-skill `use_count`, `view_count`, `patch_count`,
  `last_activity_at`, `state`, `pinned`.

Config: `curator.*` (`enabled`, `interval_hours`, `min_idle_hours`,
`stale_after_days`, `archive_after_days`, `backup.*`).
User docs: https://hermes-agent.nousresearch.com/docs/user-guide/features/curator

### Kanban (multi-agent work queue)

Durable SQLite board for multi-profile / multi-worker collaboration.
Users drive it via `hermes kanban <verb>`; dispatcher-spawned workers
see a focused `kanban_*` toolset gated by `HERMES_KANBAN_TASK`, and
orchestrator profiles can opt into the broader `kanban` toolset. Normal
sessions still have zero `kanban_*` schema footprint unless configured.

- **CLI verbs (common):** `init`, `create`, `list` (alias `ls`),
  `show`, `assign`, `link`, `unlink`, `comment`, `complete`, `block`,
  `unblock`, `archive`, `tail`. Less common: `watch`, `stats`, `runs`,
  `log`, `dispatch`, `daemon`, `gc`.
- **Worker/orchestrator toolset:** `kanban_show`, `kanban_complete`,
  `kanban_block`, `kanban_heartbeat`, `kanban_comment`, `kanban_create`,
  `kanban_link`; profiles that explicitly enable the `kanban` toolset
  outside a dispatcher-spawned task also get `kanban_list` and
  `kanban_unblock` for board routing.
- **Dispatcher** runs inside the gateway by default
  (`kanban.dispatch_in_gateway: true`) — reclaims stale claims,
  promotes ready tasks, atomically claims, spawns assigned profiles.
  Auto-blocks a task after `failure_limit` consecutive spawn failures
  (default 2; configurable via `kanban.failure_limit` or per-task
  `max_retries`).
- **Isolation:** board is the hard boundary (workers get
  `HERMES_KANBAN_BOARD` pinned in env); tenant is a soft namespace
  within a board for workspace-path + memory-key isolation.

## Windows-Specific Quirks

Hermes runs natively on Windows (PowerShell, cmd, Windows Terminal, git-bash
mintty, VS Code integrated terminal). Most of it just works, but a handful
of differences between Win32 and POSIX have bitten us — document new ones
here as you hit them so the next person (or the next session) doesn't
rediscover them from scratch.

### Input / Keybindings

**Alt+Enter doesn't insert a newline.** Windows Terminal intercepts Alt+Enter
at the terminal layer to toggle fullscreen — the keystroke never reaches
prompt_toolkit. Use **Ctrl+Enter** instead. Windows Terminal delivers
Ctrl+Enter as LF (`c-j`), distinct from plain Enter (`c-m` / CR), and the
CLI binds `c-j` to newline insertion on `win32` only (see
`_bind_prompt_submit_keys` + the Windows-only `c-j` binding in `cli.py`).
Side effect: the raw Ctrl+J keystroke also inserts a newline on Windows —
unavoidable, because Windows Terminal collapses Ctrl+Enter and Ctrl+J to
the same keycode at the Win32 console API layer. No conflicting binding
existed for Ctrl+J on Windows, so this is a harmless side effect.

mintty / git-bash behaves the same (fullscreen on Alt+Enter) unless you
disable Alt+Fn shortcuts in Options → Keys. Easier to just use Ctrl+Enter.

**Diagnosing keybindings.** Run `python scripts/keystroke_diagnostic.py`
(repo root) to see exactly how prompt_toolkit identifies each keystroke
in the current terminal. Answers questions like "does Shift+Enter come
through as a distinct key?" (almost never — most terminals collapse it
to plain Enter) or "what byte sequence is my terminal sending for
Ctrl+Enter?" This is how the Ctrl+Enter = c-j fact was established.

### Config / Files

**HTTP 400 "No models provided" on first run.** `config.yaml` was saved
with a UTF-8 BOM (common when Windows apps write it). Re-save as UTF-8
without BOM. `hermes config edit` writes without BOM; manual edits in
Notepad are the usual culprit.

### `execute_code` / Sandbox

**WinError 10106** ("The requested service provider could not be loaded
or initialized") from the sandbox child process — it can't create an
`AF_INET` socket, so the loopback-TCP RPC fallback fails before
`connect()`. Root cause is usually **not** a broken Winsock LSP; it's
Hermes's own env scrubber dropping `SYSTEMROOT` / `WINDIR` / `COMSPEC`
from the child env. Python's `socket` module needs `SYSTEMROOT` to locate
`mswsock.dll`. Fixed via the `_WINDOWS_ESSENTIAL_ENV_VARS` allowlist in
`tools/code_execution_tool.py`. If you still hit it, echo `os.environ`
inside an `execute_code` block to confirm `SYSTEMROOT` is set. Full
diagnostic recipe in `references/execute-code-sandbox-env-windows.md`.

### Testing / Contributing

**`scripts/run_tests.sh` doesn't work as-is on Windows** — it looks for
POSIX venv layouts (`.venv/bin/activate`). The Hermes-installed venv at
`venv/Scripts/` has no pip or pytest either (stripped for install size).
Workaround: install `pytest + pytest-xdist + pyyaml` into a system Python
3.11 user site, then invoke pytest directly with `PYTHONPATH` set:

```bash
"/c/Program Files/Python311/python" -m pip install --user pytest pytest-xdist pyyaml
export PYTHONPATH="$(pwd)"
"/c/Program Files/Python311/python" -m pytest tests/foo/test_bar.py -v --tb=short -n 0
```

Use `-n 0`, not `-n 4` — `pyproject.toml`'s default `addopts` already
includes `-n`, and the wrapper's CI-parity guarantees don't apply off POSIX.

**POSIX-only tests need skip guards.** Common markers already in the codebase:
- Symlinks — elevated privileges on Windows
- `0o600` file modes — POSIX mode bits not enforced on NTFS by default
- `signal.SIGALRM` — Unix-only (see `tests/conftest.py::_enforce_test_timeout`)
- Winsock / Windows-specific regressions — `@pytest.mark.skipif(sys.platform != "win32", ...)`

Use the existing skip-pattern style (`sys.platform == "win32"` or
`sys.platform.startswith("win")`) to stay consistent with the rest of the
suite.

### Path / Filesystem

**Line endings.** Git may warn `LF will be replaced by CRLF the next time
Git touches it`. Cosmetic — the repo's `.gitattributes` normalizes. Don't
let editors auto-convert committed POSIX-newline files to CRLF.

**Forward slashes work almost everywhere.** `C:/Users/...` is accepted by
every Hermes tool and most Windows APIs. Prefer forward slashes in code
and logs — avoids shell-escaping backslashes in bash.

## Troubleshooting

### Voice not working
1. Check `stt.enabled: true` in config.yaml
2. Verify provider: `pip install faster-whisper` or set API key
3. In gateway: `/restart`. In CLI: exit and relaunch.

### Tool not available
1. `hermes tools` — check if toolset is enabled for your platform
2. Some tools need env vars (check `.env`)
3. `/reset` after enabling tools

### Model/provider issues
1. `hermes doctor` — check config and dependencies
2. `hermes auth` — re-authenticate OAuth providers (or `hermes auth add <provider>`)
3. Check `.env` has the right API key
4. **Copilot 403**: `gh auth login` tokens do NOT work for Copilot API. You must use the Copilot-specific OAuth device code flow via `hermes model` → GitHub Copilot.

### Changes not taking effect
- **Tools/skills:** `/reset` starts a new session with updated toolset
- **Config changes:** In gateway: `/restart`. In CLI: exit and relaunch.
- **Code changes:** Restart the CLI or gateway process

### Skills not showing
1. `hermes skills list` — verify installed
2. `hermes skills config` — check platform enablement
3. Load explicitly: `/skill name` or `hermes -s name`

### Gateway issues
Check logs first:
```bash
grep -i "failed to send\|error" ~/.hermes/logs/gateway.log | tail -20
```

Common gateway problems:
- **Gateway dies on SSH logout**: Enable linger: `sudo loginctl enable-linger $USER`
- **Gateway dies on WSL2 close**: WSL2 requires `systemd=true` in `/etc/wsl.conf` for systemd services to work. Without it, gateway falls back to `nohup` (dies when session closes).
- **Gateway crash loop**: Reset the failed state: `systemctl --user reset-failed hermes-gateway`

### Platform-specific issues
- **Discord bot silent**: Must enable **Message Content Intent** in Bot → Privileged Gateway Intents.
- **Slack bot only works in DMs**: Must subscribe to `message.channels` event. Without it, the bot ignores public channels.
- **Windows-specific issues** (`Alt+Enter` newline, WinError 10106, UTF-8 BOM config, test suite, line endings): see the dedicated **Windows-Specific Quirks** section above.

### Auxiliary models not working
If `auxiliary` tasks (vision, compression, session_search) fail silently, the `auto` provider can't find a backend. Either set `OPENROUTER_API_KEY` or `GOOGLE_API_KEY`, or explicitly configure each auxiliary task's provider:
```bash
hermes config set auxiliary.vision.provider <your_provider>
hermes config set auxiliary.vision.model <model_name>
```

Config: `~/.hermes/config.yaml` (settings), `~/.hermes/.env` (API keys).

### Adding a Tool (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 to `toolsets.py`** → `_HERMES_CORE_TOOLS` list.

Auto-discovery: any `tools/*.py` file with a top-level `registry.register()` call is imported automatically — no manual list needed.

All handlers must return JSON strings. Use `get_hermes_home()` for paths, never hardcode `~/.hermes`.

### Adding a Slash Command

1. Add `CommandDef` to `COMMAND_REGISTRY` in `hermes_cli/commands.py`
2. Add handler in `cli.py` → `process_command()`
3. (Optional) Add gateway handler in `gateway/run.py`

All consumers (help text, autocomplete, Telegram menu, Slack mapping) derive from the central registry automatically.

### Agent Loop (High Level)

```
run_conversation():
  1. Build system prompt
  2. Loop while iterations < max:
     a. Call LLM (OpenAI-format messages + tool schemas)
     b. If tool_calls → dispatch each via handle_function_call() → append results → continue
     c. If text response → return
  3. Context compression triggers automatically near token limit
```

### Testing

```bash
python -m pytest tests/ -o 'addopts=' -q   # Full suite
python -m pytest tests/tools/ -q            # Specific area
```

- Tests auto-redirect `HERMES_HOME` to temp dirs — never touch real `~/.hermes/`
- Run full suite before pushing any change
- Use `-o 'addopts='` to clear any baked-in pytest flags

**Windows contributors:** `scripts/run_tests.sh` currently looks for POSIX venvs (`.venv/bin/activate` / `venv/bin/activate`) and will error out on Windows where the layout is `venv/Scripts/activate` + `python.exe`. The Hermes-installed venv at `venv/Scripts/` also has no `pip` or `pytest` — it's stripped for end-user install size. Workaround: install pytest + pytest-xdist + pyyaml into a system Python 3.11 user site (`/c/Program Files/Python311/python -m pip install --user pytest pytest-xdist pyyaml`), then run tests directly:

```bash
export PYTHONPATH="$(pwd)"
"/c/Program Files/Python311/python" -m pytest tests/tools/test_foo.py -v --tb=short -n 0
```

Use `-n 0` (not `-n 4`) because `pyproject.toml`'s default `addopts` already includes `-n`, and the wrapper's CI-parity story doesn't apply off-POSIX.

**Cross-platform test guards:** tests that use POSIX-only syscalls need a skip marker. Common ones already in the codebase:
- Symlink creation → `@pytest.mark.skipif(sys.platform == "win32", reason="Symlinks require elevated privileges on Windows")` (see `tests/cron/test_cron_script.py`)
- POSIX file modes (0o600, etc.) → `@pytest.mark.skipif(sys.platform.startswith("win"), reason="POSIX mode bits not enforced on Windows")` (see `tests/hermes_cli/test_auth_toctou_file_modes.py`)
- `signal.SIGALRM` → Unix-only (see `tests/conftest.py::_enforce_test_timeout`)
- Live Winsock / Windows-specific regression tests → `@pytest.mark.skipif(sys.platform != "win32", reason="Windows-specific regression")`

**Monkeypatching `sys.platform` is not enough** when the code under test also calls `platform.system()` / `platform.release()` / `platform.mac_ver()`. Those functions re-read the real OS independently, so a test that sets `sys.platform = "linux"` on a Windows runner will still see `platform.system() == "Windows"` and route through the Windows branch. Patch all three together:

```python
monkeypatch.setattr(sys, "platform", "linux")
monkeypatch.setattr(platform, "system", lambda: "Linux")
monkeypatch.setattr(platform, "release", lambda: "6.8.0-generic")
```

See `tests/agent/test_prompt_builder.py::TestEnvironmentHints` for a worked example.

### Extending the system prompt's execution-environment block

Factual guidance about the host OS, user home, cwd, terminal backend, and shell (bash vs. PowerShell on Windows) is emitted from `agent/prompt_builder.py::build_environment_hints()`. This is also where the WSL hint and per-backend probe logic live. The convention:

- **Local terminal backend** → emit host info (OS, `$HOME`, cwd) + Windows-specific notes (hostname ≠ username, `terminal` uses bash not PowerShell).
- **Remote terminal backend** (anything in `_REMOTE_TERMINAL_BACKENDS`: `docker, singularity, modal, daytona, ssh, managed_modal`) → **suppress** host info entirely and describe only the backend. A live `uname`/`whoami`/`pwd` probe runs inside the backend via `tools.environments.get_environment(...).execute(...)`, cached per process in `_BACKEND_PROBE_CACHE`, with a static fallback if the probe times out.
- **Key fact for prompt authoring:** when `TERMINAL_ENV != "local"`, *every* file tool (`read_file`, `write_file`, `patch`, `search_files`) runs inside the backend container, not on the host. The system prompt must never describe the host in that case — the agent can't touch it.

Full design notes, the exact emitted strings, and testing pitfalls:
`references/prompt-builder-environment-hints.md`.

**Refactor-safety pattern (POSIX-equivalence guard):** when you extract inline logic into a helper that adds Windows/platform-specific behavior, keep a `_legacy_<name>` oracle function in the test file that's a verbatim copy of the old code, then parametrize-diff against it. Example: `tests/tools/test_code_execution_windows_env.py::TestPosixEquivalence`. This locks in the invariant that POSIX behavior is bit-for-bit identical and makes any future drift fail loudly with a clear diff.

### Commit Conventions

```
type: concise subject line

Optional body.
```

Types: `fix:`, `feat:`, `refactor:`, `docs:`, `chore:`

### Key Rules

- **Never break prompt caching** — don't change context, tools, or system prompt mid-conversation
- **Message role alternation** — never two assistant or two user messages in a row
- Use `get_hermes_home()` from `hermes_constants` for all paths (profile-safe)
- Config values go in `config.yaml`, secrets go in `.env`
- New tools need a `check_fn` so they only appear when requirements are met
