Walkthrough

Updates downgrade AI SDK dependencies, refactor chat message rendering to use UI context with per-role components, remove the old MessageList, adjust message content styling/props, introduce introspection-aware streaming states, and change tool-call flow to await results and return values directly via a revised async handleToolCall. Hook integration is updated accordingly.

Changes

Cohort / File(s)	Summary
Dependency version updates apps/web/client/package.json, packages/ai/package.json, packages/models/package.json	Downgrade versions: @ai-sdk/react 2.0.44→2.0.25; ai 5.0.44→5.0.26 (app and packages, including devDependency).
Chat rendering refactor apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-messages/index.tsx, .../chat-messages/message-list.tsx	Replace MessageList with inline per-role rendering using useChatContext; memoized filtering of streaming assistant message; updated contentKey; removed MessageList component (file deleted).
Message content styling/props .../chat-messages/message-content/index.tsx	Remove cn usage; make reasoning block styling unconditional; pass additional props to MarkdownRenderer (applied, isStream, className); always constrain height/scroll.
Streaming state and introspection .../chat-messages/stream-message.tsx	Memoize assistant-stream role; detect reasoning parts; split waiting UI: “Thinking ...” vs “Introspecting...”; render MessageContent only for assistant stream with parts.
Tool call flow changes apps/web/client/src/app/project/[id]/_hooks/use-chat.tsx, apps/web/client/src/components/tools/tools.ts	handleToolCall rewritten to async returning result; signature changed (remove callback). Hook now awaits result and calls chat.addToolResult with structured payload (tool, toolCallId, output). Simplified error handling and tool resolution.

Poem

A rabbit taps the keys with glee,
Streaming thoughts like gentle sea.
“Introspecting,” whispers bright—
Then “Thinking...” hops into the light.
Tools now answer, clean and fast,
Messages line up at last.
Carrots compiled—ship it past! 🥕🚀
