Tools reference·

28 tools in 16 modules, generated from the @tool functions in tools/ at every docs build (scripts/tooldoc.py): signatures come from the AST, descriptions from the docstrings the model itself reads. If a page here disagrees with the robot, the docstring is wrong — fix it there.

module tools what it covers
Motion reachy_look reachy_antennas reachy_body_turn reachy_home reachy_wake head pose, antennas, body yaw, home, wake/sleep — every angle clamped before it reaches the daemon
Expression reachy_express reachy_list_emotions the recorded-move library (emotions, dances) the personas fire while they talk
State reachy_get_state reachy_motors read the live pose and switch motor modes
Camera reachy_camera reachy_look_at capture_camera grab a frame, look at a pixel, ask the vision model a question about what TINY sees
Audio reachy_play_sound reachy_say reachy_volume speak (Piper TTS on the CM4), play a sound, set the speaker volume — “silent” means 0
Head tracking head_tracking head_tracking_status toggle the daemon's face tracker (reachy-mini ≥ 1.10) through the dashboard's tracking controller
Turn to sound turn_to_sound turn_to_sound_status turn toward whoever is talking (ReSpeaker direction of arrival) when face tracking has no lock — the dashboard's DoA turner
Vision take_photo take_photo — a frame plus a question for the multimodal model, shared by every persona
Voice bridge voice_say text → the voice persona's mouth (say/mute) from the text personas
Dispatch dispatch hand a task to another persona (voice/telegram/thinker) through the shared brain
Memory memory the cross-persona SQLite brain: remember, recall, forget
Telegram telegram send text and photos to the owner's chat from any persona
Prompts prompts read and override each persona's system prompt (override = personality note appended; FULL: replaces)
Manage messages manage_messages inspect and compact the running agent's own conversation
Manage tools manage_tools list, create and hot-load new tools at runtime
Fleet (tiny.technology MCP) use_device use_device and the other fleet tools, mounted only when TINY_MCP=1 — with the self-refusal guard

Who gets what·

Two builders in tiny.py decide which of these a persona can call:

  • build_tools() — shell, telegram, thinker: everything above plus use_github/use_spotify when importable.
  • build_voice_tools() — voice and the dashboard Ask: the latency-slim list (motion, expression, state, camera, head tracking, reachy_volume, memory, prompts, dispatch, telegram, voice_say, take_photo) — see Personas.

Fleet tools (use_device, tiny_recall, tiny_learn, …) ride along only when TINY_MCP=1 and the persona is in TINY_MCP_PERSONAS, never on a turn that itself arrived from another device — see Fleet.
