// The reasoning-chain cell composes two patterns into one chat surface:
|
||
// - Reasoning-summary streaming (OpenAI Responses API, `reasoning={
|
||
// "effort":"medium","summary":"detailed"}`) rendered through a
|
||
// `messageView.reasoningMessage` slot (<ReasoningBlock>).
|
||
// - Per-tool renderers wired via `useRenderTool` for `get_weather` and
|
||
// `search_flights`, plus a `useDefaultRenderTool` catchall that
|
||
// paints `get_stock_price` and `roll_dice`.
|
||
//
|
||
// Every pill drives a CHAINED two-tool flow:
|
||
// - Stocks: get_stock_price(AAPL) → get_stock_price(MSFT) → comparison.
|
||
// - Dice: roll_dice(sides=20) → roll_dice(sides=6) → contrast.
|
||
// - Flights+weather: search_flights(SFO,JFK) → get_weather(JFK) → plan.
|
||
//
|
||
// Aimock fixtures live in showcase/aimock/d5-all.json (and the matching
|
||
// harness source at showcase/harness/fixtures/d5/tool-rendering-
|
||
// reasoning-chain.json) and pin every pill to a deterministic two-leg
|
||
// chain. The sequential-pills test is the regression guard for the
|
||
// AG-UI reasoning-role message bug in @copilotkit/runtime — without
|
||
// `LangGraphAgent.run`'s reasoning-role filter, clicking a second pill
|
||
// in the same thread used to crash with INCOMPLETE_STREAM because
|
||
// @ag-ui/langgraph's message converter throws on `role:"reasoning"`.
