# 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.

```

**⚠️ Provider config is NOT inherited across profiles.** If your default profile defines a custom provider under `providers:`, agent profiles using that provider must define it themselves or they will fail with "Unknown provider" at runtime. Copy the `providers.*` block into each agent profile's `config.yaml`. See `multi-agent-team-architecture` skill for the full setup pattern.

### Bulk-set model and provider across all profiles

Hermes profiles do **not** inherit `model.*` or `providers.*` from the default profile. Each profile has its own `config.yaml`.

**Fast path (one-liner):**
```bash
for profile in $(hermes profile list | grep -v "Active profile" | awk '{print $1}'); do
  hermes config set --profile "$profile" model.provider noris
  hermes config set --profile "$profile" model.model vllm/moonshotai/kimi-k2.6
done
```

**Explicit list (when you know the names):**
```bash
for profile in default infra-sre nutrition-coach; do
  hermes config set --profile "$profile" model.provider noris
  hermes config set --profile "$profile" model.model vllm/moonshotai/kimi-k2.6
done
```

**⚠️ Cron jobs have their own `model`/`provider` fields.** Jobs created before the switch store the old model inside `profiles/<name>/cron/jobs.json` and ignore the new profile config at runtime. After updating a profile, patch its cron JSON too:

```python
import json
path = '/home/debian/.hermes/profiles/PROFILE_NAME/cron/jobs.json'
with open(path) as f:
    data = json.load(f)
for j in data['jobs']:
    j['model'] = 'vllm/glm-5-2-nvfp4'
    j['provider'] = 'noris'
with open(path, 'w') as f:
    json.dump(data, f, indent=2)
```

Then verify with:
```bash
hermes --profile nutrition-coach cron list  # inspect Model column
```

Then verify with `hermes doctor`. Active gateway sessions need `/restart` to pick up model/provider changes.

**⚠️ Cronjobs store their own model/provider.** Each job in `cron/jobs.json` has its own `model` and `provider` fields. Bulk-switching a profile's model via `hermes config set --profile X model.model Y` does **NOT** update existing cron jobs — they keep running on the old model. After any model migration, either:
- Patch `cron/jobs.json` directly (set `model` and `provider` on each job), or
- Recreate the jobs via `hermes cron edit`, or
- Run this one-liner per profile:
```bash
python3 -c "
import json
p = '~/.hermes/profiles/<NAME>/cron/jobs.json'
with open(p) as f: d = json.load(f)
for j in d['jobs']:
    j['model'] = 'vllm/glm-5-2-nvfp4'
    j['provider'] = 'noris'
with open(p, 'w') as f: json.dump(d, f, indent=2, ensure_ascii=False)
print(f'Updated {len(d[\"jobs\"])} jobs')
"
```

**Note on key names:** Use `model.provider` and `model.model`. Do NOT use `model.default` (older config schema).

often; if something below looks stale, run `/help` in-session for the
authoritative list or see the [live slash commands reference](https://hermes-agent.nousresearch.com/docs/reference/slash-commands).
The registry of record is `hermes_cli/commands.py` — every consumer

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 **off by default** — tool output (terminal stdout, `read_file`, web content, subagent summaries, etc.) passes through unmodified. If the user wants Hermes to auto-mask strings that look like API keys, tokens, and secrets before they enter the conversation context and logs:

```bash
hermes config set security.redact_secrets true       # enable globally
```

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

Disable again with:
```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

#### Cronjobs and Profiles: Isolation Gotchas

Cron jobs live in **per-profile `cron/jobs.json` files**, NOT in a global registry. The `hermes cron list` command shows only the jobs for the *current* active profile. If you switch profiles with `--profile`, you see that profile's jobs instead.

**Critical:** A cronjob registered in the `default` profile cannot read files from `~/.hermes/profiles/nutrition-coach/` unless the job itself is running inside that profile. If a job's prompt tells Hermes to read `profiles/nutrition-coach/plan_data/current_interview.json`, but the job is registered in `default`, the agent often guesses wrong about paths or uses stale data.

**Fix:** Move profile-specific cronjobs into the target profile's `cron/jobs.json`. Physically move the JSON entries — do NOT just add a `profile` tag. The scheduler only reads the jobs file that matches the active profile.

```python
# Move jobs from default → nutrition-coach
import json

with open('~/.hermes/cron/jobs.json') as f: default = json.load(f)
with open('~/.hermes/profiles/nutrition-coach/cron/jobs.json') as f: nc = json.load(f)

moved, remaining = [], []
for j in default['jobs']:
    if 'nutrition' in j['name'].lower():
        moved.append(j); nc['jobs'].append(j)
    else:
        remaining.append(j)

default['jobs'] = remaining
# write both files back
```

After moving, verify with:
```bash
hermes cron list                          # default jobs
hermes --profile nutrition-coach cron list  # nutrition-coach jobs
```

### 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` so the
schema footprint is zero outside worker processes.

- **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 toolset:** `kanban_show`, `kanban_complete`, `kanban_block`,
  `kanban_heartbeat`, `kanban_comment`, `kanban_create`, `kanban_link`.
- **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 ~5 consecutive spawn failures.
- **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.

## 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 login` — re-authenticate OAuth providers
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

### Memory Management (MEMORY.md Maintenance)

MEMORY.md has a hard character limit (~2,200 chars). When it fills up:

1. **Audit entries** — identify entries fully covered by an existing skill (those can be dropped; the skill carries the detail)
2. **Compress remaining entries** — reduce to bare declarative facts, remove redundant qualifiers
3. **Migrate dropped/compressed detail to Hindsight** — use `hindsight_retain` with descriptive tags so the info remains searchable via `hindsight_recall`/`hindsight_reflect`
4. **Target ~50% utilization** after cleanup to leave room for future entries

Pattern: `memory(action="remove")` to drop, `memory(action="replace")` to compress in-place, `hindsight_retain` to archive detail. Verify with the usage percentage returned by each memory operation.

### 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`

### Auxiliary model fails with network/DNS error

If auxiliary tasks (title_generation, vision, compression, session_search, etc.) fail with `HTTP 400: network error occurred while connecting to provider API`, check whether `auxiliary.<task>` points to a custom endpoint that is unreachable.

**Fix:** Set auxiliary tasks to `auto` so they fall back to the main model:

```bash
# Single task
hermes config set auxiliary.title_generation.provider auto
hermes config set auxiliary.title_generation.model ''
hermes config set auxiliary.title_generation.base_url ''
hermes config set auxiliary.title_generation.api_key ''

# Bulk-fix all auxiliary tasks across all profiles
for profile in default infra-sre nutrition-coach; do
  for task in vision web_extract compression session_search skills_hub approval mcp title_generation flush_memories; do
    hermes config set --profile $profile auxiliary.$task.provider auto
    hermes config set --profile $profile auxiliary.$task.model ''
    hermes config set --profile $profile auxiliary.$task.base_url ''
    hermes config set --profile $profile auxiliary.$task.api_key ''
  done
done
```

Then `/reset` (CLI) or `/restart` (gateway) for the change to take effect.

### 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 HTTP 400 "No models provided"**: Config file encoding issue (BOM). Ensure `config.yaml` is saved as UTF-8 without BOM.

### vision_analyze fails with "no providers found for model"

The `vision_analyze` tool defaults to `gpt-4o-mini` when `auxiliary.vision` is unset. On custom providers (noris, self-hosted vLLM, etc.) this model doesn't exist, causing:

```
provider is required in model field (format: provider/model) — no providers found for model "gpt-4o-mini" in model catalog to auto-resolve
```

**Fix:** Explicitly set `auxiliary.vision` to a vision-capable model on your provider:

```bash
hermes config set auxiliary.vision.provider noris
hermes config set auxiliary.vision.model anthropic/claude-haiku-4-5-20251001
hermes config set auxiliary.vision.base_url ''
hermes config set auxiliary.vision.api_key ''
```

This takes effect immediately — no restart needed. Verify with a test call to `vision_analyze`.

**Vision-capable models at noris (as of 2026-06-27):** All `anthropic/claude-*` models support vision. The vLLM models generally do NOT (text-only deployments).

### Auxiliary models not working

Symptom: `Auxiliary title generation failed: HTTP 400: network error occurred while connecting to provider API` or similar 400/connection errors.

**Stale custom endpoint** — A common root cause is that `auxiliary.*` tasks point to a `custom` provider with a `base_url` (e.g. `http://10.0.30.99:8080/v1`) that no longer exists or returns 400. Check the config:
```bash
hermes config | grep -A 3 "Auxiliary"
```

Fix: reset the broken auxiliary to fall back to `auto` (uses the main model):
```bash
hermes config set auxiliary.title_generation.provider auto
hermes config set auxiliary.title_generation.model ''
hermes config set auxiliary.title_generation.base_url ''
hermes config set auxiliary.title_generation.api_key ''
```

**Bulk reset across all profiles** — When migrating the entire stack to a new provider, every profile may carry stale `custom` auxiliary overrides. Kick this script once to set all commonly-defined auxiliary slots to `auto` across all profiles:
```python
import subprocess

profiles = ['default', 'infra-sre', 'nutrition-coach']  # adapt to your profiles
slots = [
    'vision', 'web_extract', 'compression', 'session_search',
    'skills_hub', 'approval', 'mcp', 'title_generation', 'flush_memories',
]
for p in profiles:
    for s in slots:
        for k, v in [('provider', 'auto'), ('model', ''), ('base_url', ''), ('api_key', '')]:
            subprocess.run(
                ['hermes', 'config', 'set', '--profile', p, f'auxiliary.{s}.{k}', v],
                capture_output=True)
```

**Alternative: forward all auxiliary tasks to a working endpoint** — If you prefer a consistent auxiliary model, explicitly configure each slot instead of `auto`:
```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

### 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
