tool chips

# agent-ui / tool-chips
component: tool-chips
selector: .au-tool-chips
data_au_component: tool-chips
purpose: Collapsible compact tool/message chip stack.

install:
  - tokens.css
  - tool-chips.css
  - button.css when rendering actions

states: Host-owned via data-au-state and documented variants.
css_variables: Uses shared semantic tokens.
events: native form, focus, and click only — no custom events or runtime required
no_javascript: Markup and native controls remain usable without script.
host_owns: The host owns content, state transitions, and execution behind actions.
accessibility: Prefer labelled regions and text status, not color alone.
security: Escape untrusted model and tool text before insertion.

rules:
  - Host owns execution, authorization, persistence, validation, and state transitions.
  - Components render host-provided state; they never execute tools or imply approval.
  - Escape untrusted model output, tool args, and tool output before insertion.
  - Use only documented data-au-* attributes and data-au-state values.
  - Keep the no-JS path usable. Do not add React, Tailwind, bundlers, or remote assets.
