### Toolsets

Enable/disable via `hermes tools` (interactive) or `hermes tools enable/disable NAME`.
Full enumeration: `TOOLSETS` dict in `toolsets.py` (`_HERMES_CORE_TOOLS` is the default bundle most platforms inherit).

| Toolset | What it provides |
|---------|-----------------|
| `web` / `search` | Web search + extraction / search-only subset |
| `browser` | Browser automation (Browserbase, Camofox, or local Chromium) |
| `terminal` | Shell commands and process management |
| `file` | File read/write/search/patch |
| `code_execution` | Sandboxed Python execution |
| `coding` | Code-editing helpers (LSP-backed) |
| `computer_use` | Desktop GUI control (cua-driver) |
| `vision` | Image analysis |
| `image_gen` | Image generation and image-to-image editing |
| `video` / `video_gen` | Video analysis / video generation |
| `x_search` | X (Twitter) search (X OAuth or API key) |
| `tts` | Text-to-speech |
| `skills` | Skill browsing and management |
| `memory` | Persistent cross-session memory |
| `session_search` | Search past conversations |
| `context_engine` | Pluggable context-engine hooks |
| `project` | Named multi-folder workspace tools |
| `delegation` | Subagent task delegation |
| `cronjob` | Scheduled task management |
| `clarify` | Ask user clarifying questions |
| `todo` | In-session task planning |
| `kanban` | Multi-agent work-queue tools (gated to workers) |
| `debugging` | Extra introspection tools (off by default) |
| `safe` | Minimal low-risk toolset for locked-down sessions |
| `spotify`, `homeassistant`, `discord`, `discord_admin`, `feishu_doc`, `feishu_drive`, `yuanbao` | Service integrations (gated on their credentials) |

Tool changes take effect on `/reset` (new session) — never mid-conversation, to preserve prompt caching.

## Voice

### STT (Voice → Text)

Voice messages from messaging platforms are auto-transcribed.

```yaml
stt:
  enabled: true
  provider: local   # local (faster-whisper, free) | groq | openai | mistral | elevenlabs | deepinfra
  local:
    model: base     # tiny, base, small, medium, large-v3
```

Auto-detect priority: local faster-whisper (`pip install faster-whisper`) → Groq (`GROQ_API_KEY`, free tier) → OpenAI (`VOICE_TOOLS_OPENAI_KEY`) → Mistral Voxtral (`MISTRAL_API_KEY`).

### TTS (Text → Voice)

| Provider | Env var | Free? |
|----------|---------|-------|
| Edge TTS (default) | None | Yes |
| ElevenLabs | `ELEVENLABS_API_KEY` | Free tier |
| OpenAI | `VOICE_TOOLS_OPENAI_KEY` | Paid |
| MiniMax | `MINIMAX_API_KEY` | Paid |
| Mistral | `MISTRAL_API_KEY` | Paid |
| Gemini | `GOOGLE_API_KEY` | Free tier |
| NeuTTS / Piper / KittenTTS (local) | None | Free |

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