Activity

Host-owned activity dots — the same language as workspace status rows and CenterDock tabs. Use ActivityGlyph in your own panel / modal content when you want that signal; use setActivity / bindActivity (or workspace status activity) when pinning it onto Silo chrome.

Extensions pick a kind only. Color and motion are fixed per kind (pinned light/dark palette — not --silo-color-* theme accents). Never invent a spinner or recolor the glyph.

workingreadywarnerroromit (neutral)

import { ActivityGlyph, type Activity } from "@silo-code/sdk";

<ActivityGlyph activity="working" size="md" />
<ActivityGlyph activity="ready" />
<ActivityGlyph activity="warn" />
<ActivityGlyph activity="error" />
<ActivityGlyph size="sm" />  // omit activity → gray neutral

Prop	Type	Default	Notes
activity	"working" | "ready" | "warn" | "error"?	—	Omit only for the gray neutral fallback
size	"sm" | "md"	"sm"	sm ≈ workspace rows (6px); md ≈ tabs (8px)

Kinds

Kind	Means	Look
working	In progress	Blue dot + expanding rings
ready	Available / waiting for input	Green subtle throb
warn	Needs caution	Amber static
error	Failed	Red static
(omit)	Neutral / unconfirmed	Gray static — workspace status rows only; in panels prefer omitting the glyph

These four are the whole vocabulary — never invent a fifth activity tint. For text pills (Installed, Update available), use Badge instead.

vs Badge

	Activity	Badge
Shape	Dot (+ motion)	Text pill
Color	Host-fixed per kind	Tone or arbitrary identity color
Typical use	Process / agent state	Labels, counts, provenance

Projecting agent state

import { ActivityGlyph, activityFromAgent } from "@silo-code/sdk";

const activity = activityFromAgent(agent.activity); // null for none / dead
{
  activity && <ActivityGlyph activity={activity} size="sm" />;
}

AgentActivity	UI Activity
working	working
idle	ready
error	error
none / dead	no glyph
