AI Chat Components

Components built for AI chat scenarios: message bubbles, reasoning chains, tool calls, agent status, plans and test results, cited sources, code diffs, terminals, file trees, artifacts, and more. Each example shows the formatted, highlighted TokUI DSL on the left and the live render on the right; click "Edit" to tweak it instantly.

Reasoning Block `think`

A collapsible reasoning-process container, closed by [/think]. open expands by default, tt sets the title.

HITL human approval: with approval plus status:pending, the card renders Approve / Reject buttons. The user's decision is reported back through the clk: handler (or on:"approval:h") as {approved, id, name}; once decided, the buttons are disabled and the follow-up status is pushed by the server via upd.

;; after the user clicks, onApproval receives {approved:true/false, id:"tc1", name:"delete_file"}
;; the server then pushes the follow-up status:

Send reporting: Enter / the send button triggers the clk handler (payload {value}) and also reports a send event (detail {value}) through on:"send:h" and the unified outlet.

@ mentions: mention:data-source-handler enables the @-mention dropdown — typing @ triggers it; the data source fn({value: query}) returns an array or a Promise (items are strings or {v, tx}); ↑↓ navigates, Enter selects, Esc closes (keys take precedence over sending). Selecting inserts @label and reports the mention event {value, name}.

Stop generating: adding the streaming boolean prop swaps the send button for a "stop generating" button (the two are mutually exclusive). Clicking it fires the on:"stop:h" report (detail {}); when no on is declared, the default behavior is to disconnect the SSE connection of the TokUI instance that owns this component (disconnect(), idempotent and safe — on multi-instance pages it won't stop other instances), and the input immediately returns to the send state (optimistic UI — if the stream hasn't actually stopped, the server can restore it with upd streaming:true). When generation finishes, the server pushes [upd id:x streaming:false] to restore the send button; streaming:true re-enters the generating state.
