## Summary
- Remove `@langchain/community` from `@copilotkit/sdk-js`
peerDependencies — it's declared as `^0.3.58` but never imported
anywhere in the package
- This was the only constraint blocking `@langchain/core@1.x` resolution
for consumers using the LangGraph JS starter
## Context
`@copilotkit/sdk-js` has zero imports from `@langchain/community`. The
`^0.3.58` peer dep forced npm to resolve `@langchain/community@0.3.x`,
which transitively pulled in `@getzep/zep-cloud` → `langchain@0.3.x`,
conflicting with `sdk-js`'s own `langchain@>=1.0.0` peer requirement.
Removing the unused peer dep eliminates this resolution conflict
entirely.
## Test plan
- [ ] `npm install` in a fresh project using `@copilotkit/sdk-js`
resolves without peer dep warnings for `@langchain/community`
- [ ] Existing LangGraph JS starter installs cleanly
- [ ] No runtime behavior change (nothing imported from the removed dep)
@copilotkit/sdk-js declares @langchain/community as a peer dependency
but never imports from it. The ^0.3.58 constraint was the only thing
blocking @langchain/core@1.x resolution for consumers. Remove it
entirely since it serves no purpose.
Tests the /debug-events SSE endpoint across Express, Hono, Node, and
Fetch Direct adapters. Verifies SSE response format, event flow through
the DebugEventBus, envelope structure (timestamp, agentId, threadId,
runId, event), full event sequence, HTTP method validation (405 for
POST), and NODE_ENV=production guard (404).
Key implementation detail: reader.cancel() must NOT be awaited on
tee'd ReadableStreams (created by response.clone() in the fetch
handler) because Node.js blocks until the other tee branch is also
consumed/cancelled.
## Summary
- Fixes#2986
- `reqOrRequest instanceof Request` fails when `@hono/node-server`
polyfills the Request class with a different prototype
- Replaced with a duck-type check (`isRequestLike`) that verifies `url`,
`method`, and `headers` properties exist
- The `!res` guard ensures IncomingMessage objects (which always come
with a ServerResponse) are still routed correctly
## Test plan
- [x] Added `request-duck-type.test.ts` covering native Request,
polyfilled Request, null/undefined, and missing properties
- [x] All 1225 existing runtime tests pass
- [x] Build passes
Three React components for the AG-UI event inspector webview:
- FilterBar: category toggles, text search, agent/run dropdowns
- EventList: scrollable event stream with sticky auto-scroll and event summaries
- EventDetail: side panel with metadata display and collapsible JSON tree viewer
## Summary
- `sendMessage` returns `Promise<void>` but `usePushToTalk` accessed
`.id` on the result, causing a `TypeError` crash during push-to-talk
transcription
- Added guard to check if `sendFunction` returns a message before
accessing `.id`
- Updated `SendFunction` type to accept `Promise<Message | void>`
Fixes#3011
## Test plan
- [x] Added unit tests verifying void return handling
- [x] Added unit tests verifying message-with-id return handling
- [x] All react-ui tests pass
## Summary
- `.copilotKitMessagesFooter` used `width: 97%` which caused horizontal
overflow in constrained containers
- Changed to `width: 100%` with `box-sizing: border-box` so padding is
included in the width calculation
Fixes#2325
## Test plan
- [x] All react-ui tests pass
- [ ] Visual verification: render CopilotKit chat in a constrained
container (e.g. 300px sidebar) and confirm no horizontal scrollbar
appears
## Summary
Fixes#2194
`CopilotModal` and `CopilotModalProps` were not exported from
`@copilotkit/react-ui`, making them inaccessible to consumers. Adds both
exports to the chat barrel file.
## Test plan
- [ ] Verify `CopilotModal` and `CopilotModalProps` are importable from
`@copilotkit/react-ui`
## Summary
- `Button` component wrapped with `React.forwardRef` to fix ref warning
from Radix UI's `DropdownMenuTrigger asChild` pattern
Closes#2947
## Test plan
- [x] All affected packages build successfully

## Summary
- The loading spinner only appeared when the last message had role
"user"
- During tool execution the last message can have role "tool", hiding
the indicator
- Now also show it when the trailing message is a tool result
Closes#3055
## Summary
- Skips keydown handling during IME composition (e.g. CJK input) by
checking `isComposing`/`keyCode 229`
- Guards textarea measurement from resetting value mid-composition,
which would break the composition session
Closes#3318
## Summary
- Always calls `onChange("")` after send in controlled mode so the
parent component is notified to clear its state
- Previously `onChange` was only called inside the `!isControlled`
branch, leaving controlled parents unaware the input was submitted
Closes#3593
Closes#1921
The Markdown component accepted `components` but not `urlTransform`,
preventing users from customizing URL sanitization. Added `urlTransform`
as an optional prop with passthrough to `MemoizedReactMarkdown`.
Split from #3838.
## Summary
- `buildFrontendTools` only checked `tool.available !== false` but the
`available` field can also be the string `"disabled"`, which is truthy
- Added `tool.available !== "disabled"` to the filter so disabled tools
are properly excluded
- Added test verifying tools with `available: "disabled"` are filtered
out
## Test plan
- [x] New test: tool with `available: "disabled"` is excluded from
`buildFrontendTools`
- [x] All existing available-filtering tests still pass
- [x] Full core test suite passes (338 tests)
## Summary
- onThumbsUp/onThumbsDown/onReadAloud/onRegenerate callbacks on
CopilotChatAssistantMessage were receiving the browser SyntheticEvent
instead of the AssistantMessage object
- Wrapped the onClick handlers to pass the message explicitly:
`onClick={() => onThumbsUp(message)}`
- Same fix applied to onReadAloud and onRegenerate for consistency
## Test plan
- [x] Red-green verified: test confirms callback arg has `id`, `role`,
`content` and NOT `nativeEvent`/`target`
- [x] Full react-core test suite passes (1071 tests)
- [x] Build passes
Closes#3457
## Summary
- useRenderCustomMessages threw "Agent not found" when the agent was
undefined during the connecting state
- Changed the throw to return null, allowing the component to render
gracefully while the agent is being resolved
## Test plan
- [x] Red-green verified: test calls hook with nonexistent agent,
asserts returns null not throws
- [x] Full react-core test suite passes (1071 tests)
- [x] Build passes
Closes#3497
## Summary
- CopilotListeners called useAgent() unconditionally, which throws when
no agents are registered and no runtimeUrl is configured
- Split into CopilotListeners (outer, handles error subscription) and
CopilotListenersAgentSubscription (inner, uses useAgent)
- Inner component only renders when agents exist or a runtime is
configured
## Test plan
- [x] Red-green verified: render CopilotListeners with no agents, assert
no throw
- [x] Full react-core test suite passes (1071 tests)
- [x] Build passes
Closes#3249
## Summary
- `checkForUpdates()` in dev console is now gated on `showDevConsole`,
preventing unnecessary network requests when the console is disabled
Closes#2751
## Test plan
- [x] `@copilotkit/react-core` tests pass

## Summary
- LangChain adapter now always uses `randomId()` for message stream IDs
instead of relying on `lc_kwargs.id` (which GoogleGenerativeAI sets to
`"0"` for all messages)
Closes#2929
## Test plan
- [x] `@copilotkit/runtime` tests pass
