workled MCP Controller

Mandatory State Protocol

Call set_agent_state via MCP on every state transition:

State	When
thinking	First tool call of every reply; user submits a message
idle	Turn finished; session torn down
input	Any time the agent is waiting on the user — calling an input tool (question/ask/confirm), sitting inside a client-side modal (hermes _confirm_destructive_slash, etc.), or after rendering a plain-text choice list / multi-option question and waiting for the user's pick
error	Runtime error occurred

Per-turn procedure (execute every turn, in order):

1. Turn starting / user message received → set_agent_state("thinking") — first action, before any other tool call.
2. Before rendering options / choices / opening any modal / asking a question → set_agent_state("input").
3. End of turn, work done, no more output pending → set_agent_state("idle").
4. Runtime error / failed tool call → set_agent_state("error").

Pre-Reply Gate — check BEFORE emitting your final visible message:

• Did I call set_agent_state at least once this turn?
• Does the LED state match what I'm about to show (idle if done, input if asking, thinking if still working)?
• If either is NO, emit the correct set_agent_state call first, then the reply.

MCP Tool Reference

Tool	Property	Description	Usage
set_agent_state	state_name: string	Set LED to reflect agent state (thinking/idle/input/error)	set_agent_state("thinking")
set_brightness	brightness: string	LED brightness 0-255	set_brightness("128")
set_effect	effect_name: string, effect_json: string	effect_name ∈ led(manual effect)/idle/thinking/input/error; effect_json is a JSON string {"type","hue","saturation","value","speed"}. Map natural-language colors to HSV (see table below).	set_effect("led", '{"type":"breathe","hue":180,"speed":50}')
get_effect	effect_name: string	Get effect_name config as JSON	get_effect("thinking")
set_macro	macro_name: string, macro_json: string	Set the macro for a touch pad gesture; macro_name ∈ single_click/double_click/long_press_start; macro_json is a JSON array of segments (see Macro Format); empty macro_json resets	set_macro("single_click", '[{"combo":"ctrl+c"}]')
get_macro	macro_name: string	Returns the macro as a JSON array string, or empty string if unset (password values masked)	get_macro("single_click")

Mapping natural-language colors to set_effect

Use type:"solid" unless the user asks for an animation. Map a color name to HSV:

Description	type	hue	saturation	value
pure white	solid	0	0	255
warm white	solid	30	80	255
red	solid	0	255	255
orange	solid	30	255	255
yellow	solid	60	255	255
green	solid	120	255	255
cyan/teal	solid	180	255	255
blue	solid	240	255	255
purple/violet	solid	270	255	255
pink	solid	330	200	255
dim/night mode	solid	30	80	60
rainbow (animated)	rainbow	-	-	-

Rule of thumb: hue 0-359 picks the hue, saturation 0-255 (0 = white/pastel, 255 = vivid), value 0-255 brightness. Pastel/white tones use low saturation; vivid tones use 255.

Setup & Troubleshooting

If the device is not responding, run node <skill-dir>/index.js status and follow the JSON hint it prints. Full install / deployment / troubleshooting reference: device_setup.md
