📚 Reference

Generated, not hand-copied.

---

Everything below is read from the real source at request time — the AI vocabulary contract and GRAIN's token slots. Change the source, this page changes with it.

Generated from grain/ai/contract.ts's ACTIONS registry — the single source of truth. Payload fields marked * are required; hints are MCP-style behaviour flags.

verb	payload	accepts (surface kinds)	depth	hints	what it does
item.archive	no args	item	light	idempotent	Archive an item (stands in for task.complete on the optimistic light path).
say.set	text*:string	reflection	light	idempotent	Write a noted line back into a reflection surface.
say.stream	no args	say-stream	light	idempotent	Stream a reflection line out token by token.
demo.run	no args	screen	heavy	idempotent	Play a scripted AI-acting demo on the current screen.
desk.stop	no args	screen	light	readOnly, idempotent	Ask the AI to halt the current run (mediated — never a force-kill).
chat.send	text*:string	chat-log	light	—	Send a chat message; the AI's reply streams back over SSE.
note.append	text*:string (markdown)	notepad	light	—	Append one markdown entry to the notepad.
note.replace	text*:string (markdown)	notepad	light	destructive, idempotent	Rewrite the whole notepad from one markdown body.
navigate	href*:string (root-relative path, e.g. /notes)	screen	light	readOnly, idempotent	Change screens — same-origin, root-relative href only (validated at the door).
field.set	value*:string (plain text; replaces the field's current value)	field	light	destructive, idempotent	Prefill a registered form field with drafted text — the human reviews and submits; the AI never submits.

Every kind at least one verb above accepts.

The effect kinds the client dispatcher applies (see AI-INTERFACE.md).

op	means
replace	swap the target's HTML — the confirmed/committed fragment
append	add HTML to the end of the target (a chat log, a plan list, the console)
remove	delete the target element
flash	a transient note; also rolls back an optimistic pending state
type	stream one text token into the target, or (done) settle it
spotlight	show the AI as actor — dim everything, light (and optionally pulse) the target
log	append one provenance-tagged entry to the interaction timeline (the unified human+AI log)
navigate	change the browser's location (href) — same-origin, root-relative only
choices	the AI asks the human to pick — a chat bubble with a row of choice buttons (each a chat.send)
fill	prefill a registered form field's value — persists for human review (the AI never submits)

The HTTP surface every human/AI interaction enters through.

endpoint	means
POST /intent	the one door — every human/AI interaction enters here
GET /stream	the per-session SSE channel render ops are pushed back over
GET /ai/manifest	the machine-readable index of what's operable right now

Every custom property GRAIN's default theme sets on :root — override these to re-skin (see RE-SKIN-VIA-TOKENS.md), never a component's own CSS.
