CopilotChat message wrappers used viewport-keyed `cpk:sm:px-0`, collapsing
horizontal padding to 0 at any viewport >=640px. The message column is
`max-w-3xl` (768px) centered; the design assumes the chat fills the viewport,
so at >=640px the column has side gutters and inner padding can drop to 0.
But when the chat lives in a sub-viewport-width pane (e.g. the threads drawer
rail beside the chat, ~580px on an 820px iPad-portrait viewport), `sm:px-0`
still fires on viewport width while the 768px column overflows the narrow
pane and sits flush against both edges. The input wrapper looked fine because
it is visually inset by its own pill, so only message text appeared broken.
Make the padding container-relative instead of viewport-relative:
- add `cpk:@container` (container-type: inline-size) to the chat root, and
- switch the message/input/suggestion wrappers from `cpk:sm:px-0` to the
container variant `cpk:@3xl:px-0`.
Padding now tracks the chat's own width and drops to 0 only once the container
is at least as wide as the column's own max-width, so the column has real
gutters; in any narrower pane the `px-4` inner padding is retained. React,
Angular, and Vue kept in lockstep.
Note on the breakpoint: Tailwind v4 container-query breakpoints differ from
viewport breakpoints (`@sm` = 24rem/384px, not 640px). A mechanical
`sm:` -> `@sm:` swap would still collapse the ~580px repro pane. `@3xl`
(48rem/768px) is used because it exactly matches the column's `max-w-3xl`,
which is the width at which side gutters first appear.
Verified: full-width desktop chat unchanged (container >=768px -> px-0);
580px pane retains 16px padding; render-prop layouts without a container
ancestor degrade safely to `px-4`; sidebar/popup `data-*` padding overrides
are unaffected.

Memory, NewMemory, MemoryChanges, MemoryKind, and MemoryScope are the
memory types surfaced by the useMemories / injectMemories hook result
shapes, so export them unprefixed as supported public API instead of
behind the ɵ "internal" marker. Internal memory plumbing (MemoryStore,
the selectMemories* selectors, state/context/event types,
createMemoryStore) keeps the ɵ prefix.
Updates the react-core and angular hook signatures, the web-inspector
Memories tab, and the affected tests to the unprefixed names.
- Revert the v2 useRenderToolCall fallback: when no per-tool or wildcard renderer is
registered, return null instead of auto-painting DefaultToolCallRenderer. Showing the
card is opt-in via useDefaultRenderTool().
- The auto-card default shipped silently in v1.57.2 (commit ba60df5d33, buried in a
showcase per-tool-testids commit, no CHANGELOG entry) and leaked internal tool names +
raw args/result JSON (e.g. generate_a2ui) into every v2 app's chat in production.
- Remove the now-dead defaultToolCallRenderAdapter + __testOnly_ export + unused imports.
- Rewrite the resolver test to assert the 3-state opt-in contract: useDefaultRenderTool()
-> card, useDefaultRenderTool({render}) -> custom, no hook -> nothing.
The in-header thread-drawer launcher toggles `drawerOpen`, which only drives the
off-canvas MOBILE drawer; on desktop the drawer is a persistent in-flow panel
that ignores `open`, so the launcher was a dead no-op there (it appeared to do
nothing on click). Gate it on a reactive mobile viewport check so it renders
only at ≤767px. On desktop the chat's own open/close — the toggle FAB + the
header close (both lucide X) — is the consistent pair; nothing masquerades as a
chat control.
CopilotChatConfigurationProvider treated any `threadId` prop as controlled, so
the auto-minted non-explicit threadId that <CopilotKit>'s v1 bridge seeds
blocked the drawer's imperative setActiveThreadId/startNewThread — thread
switching and "+ New" were dead in every app wrapped in <CopilotKit>. A
non-explicit (`hasExplicitThreadId={false}`) threadId is now overridable; a
genuine caller-supplied threadId stays controlled.
Also, surfaced during the langgraph-js de-fork validation:
- CopilotChat clears messages when switching to a fresh non-explicit thread
("+ New") so the welcome screen shows instead of the prior thread — including
when a still-loading /connect is superseded by the switch.
- CopilotDrawer treats a pending (null) license status as loading, not
unlicensed, so the upgrade upsell no longer flashes or sticks before the
runtime reports the license.
Add an optional onAction interceptor to createA2UIMessageRenderer so apps
can handle A2UI actions client-side (e.g. navigate) instead of forwarding
every action to the agent.
- onAction(action, forward) runs before forwarding. Return null to handle
client-side and stop forwarding, return a modified action to forward it,
or return undefined to forward unchanged.
- Threaded from createA2UIMessageRenderer options through ReactSurfaceHost.
- Extracted runA2UIAction helper for deterministic unit testing.
- Default behavior is unchanged when onAction is not supplied.
Add <CopilotDrawer> (interops with the shadow-DOM element, two-pronged license
gate, scoped chat-input focus return, registration-gated header launcher) and
extend CopilotChatConfigurationProvider with drawerOpen + mobile mutual
exclusion + a non-explicit active-thread setter so a bare drawer connects to the
picked thread and resets on New with no host wiring. useThreads gains an
{enabled} gate and a list-only error channel.
Fixes#5635.
## What
Headers set directly on an `HttpAgent` registered via
`agents__unsafe_dev_only` were silently replaced by the provider
headers. Per-agent auth headers (like an `Authorization` for a
self-hosted backend) got dropped, causing 401s.
## Why
`AgentRegistry.applyHeadersToAgent` did `agent.headers = {
...core.headers }`, a full overwrite. The run handler and the react-core
`useAgent` hook did the same. So an agent built with its own headers
lost them on registration, on every `setHeaders`, and before each
request.
## Fix
Merge instead of replace. The registry captures each agent's own headers
once (in a WeakMap, before the first apply) and rebuilds `{
...ownHeaders, ...coreHeaders }`. Core wins on key conflicts, which
keeps the existing "provider headers are authoritative" and logout/clear
behavior. All header application now routes through one method,
`CopilotKitCore.applyHeadersToAgent`, so runs never clobber per-agent
headers.
Vue and Angular benefit too: they dispatch runs through `core.runAgent`
/ `connectAgent`, so the merge is re-applied before every request.
## Tests
- core: 3 new cases in `core-headers.test.ts` (preserve, merge,
retain-across-setHeaders); existing overwrite and clear tests still
pass.
- react-core: new `use-agent-provider-headers.e2e.test.tsx` with a real
provider and an HttpAgent that has its own headers.
Verified locally: format, lint, full core + react-core suites, and both
builds.
## Summary
Adds `unarchiveThread(id)` to the v2 thread store (`@copilotkit/core`)
and the `useThreads` hook (`@copilotkit/react-core/v2`), restoring an
archived thread via the existing generic `PATCH /threads/:id { archived:
false }` update path — no new runtime endpoint. Mirrors `archiveThread`
across the store and hook.
This is the durable, architecture-independent piece extracted from the
threads-drawer effort. The drawer UI itself is being restarted as a
framework-agnostic **CopilotDrawer** (Lit web component + React/Angular
wrappers) under a separate spec; this hook method stands on its own and
is needed regardless.
## Testing
TDD. New core store test (`PATCH … { archived: false }`) and
`useThreads` hook test; full suites green (core, react-core).
Restores an archived thread via the existing generic PATCH /threads/:id
update path with { archived: false } — the same mechanism example apps
already use for restore — so no new runtime route is required. Mirrors
archiveThread across the core thread store and the v2 useThreads hook.
Repairs TypeScript check-types across the monorepo and adds a CI gate so
regressions are caught going forward:
- core: bundler module resolution and strict-mode fixes
- sdk-js: bundler module resolution; keep codegen, formatter, packaging working
- react-core: fixes across components, hooks, and tests
- react-native: restore catch binding referenced by TypeError cause
- runtime: repair check-types and bound AI SDK schema inference
- web-inspector: nodenext import extensions, export Anchor
- remaining packages and node example: assorted check-types repairs
- deps: add missing type-only devDependencies
- license context driven from /info licenseStatus
- ci: run check-types in the static quality workflow
Squashed from 12 commits for a single, easily-revertable change.
CR round 2 follow-ups (no behavior change):
- Add a core-headers regression test proving the agentOwnHeaders baseline
stays pristine across remove + re-add (the WeakMap is intentionally not
cleared on removal; clearing would re-capture polluted headers).
- Correct the stale `headers` config doc ("appended" -> merged on top of each
HttpAgent's own headers, core wins).
- Tighten the e2e no-provider-headers assertion to toEqual.
## Summary
- Mint a GitHub App token for the stable release workflow and reuse it
for PR creation and follow-up API calls
- Disable lefthook during automation commits so release PR generation
does not depend on local developer hooks
- Relax the CopilotChat perf regression test to assert correctness
without a hard 5s wall-clock check
## Testing
- Unit/UI test updated to allow longer async rendering while still
verifying 100 messages render successfully
- Not run (not requested)
CR round 1 follow-ups (no behavior change):
- Document on setHeaders + applyHeadersToAgent that the merge baseline is the
agent's construction-time headers, so setHeaders can override but cannot
remove a per-agent header (the agent's own value re-surfaces on clear), and
that dynamic updates go through setHeaders, not direct agent.headers mutation.
- Tighten the agentOwnHeaders field comment (captured on first apply, never
re-captured) and the applyHeadersToAgent method doc.
- Add a core-headers test pinning the clear-reveals-baseline contract.
- Soften the two useAgent test-mock comments: they are an additive stand-in,
not a faithful model of core's frozen baseline.
Adds the AG-UI standard interrupt flow (RUN_FINISHED outcome:interrupt + resume array) alongside the legacy on_interrupt path.
- core: forward the standard resume array through runAgent.
- react-core / vue / react-native: useInterrupt handles standard interrupts with resolve()/cancel(), surfaces the primary + full interrupt set, and persists each resolved tool-backed interrupt as a tool-result message so multi-turn conversations stay well-formed (no dangling tool call -> no tool-call loop).
- runtime BuiltInAgent: native interrupts for the aisdk + tanstack factory paths via each SDK's needsApproval primitive (tool-approval-request / CUSTOM approval-requested -> outcome:interrupt); classic interrupt-tool emission + ctx.interrupt() factory primitive; idempotent resume injection mapped to each SDK's native tool-result; getCapabilities advertises humanInTheLoop.interrupts.
- docs: document standard interrupt support.
Verified across core/react-core/runtime unit suites and a real-model multi-turn run on both aisdk and tanstack.
HttpAgent headers configured directly on an agent registered via
agents__unsafe_dev_only were silently replaced by core headers, dropping
per-agent auth headers and causing 401s against self-hosted backends.
Core headers are now merged ON TOP of each agent's construction-time
headers (captured once in a WeakMap before the first apply), with the
core-level value winning on a key conflict. Header application is
centralized in CopilotKitCore.applyHeadersToAgent so the run handler and
the react-core useAgent hook share one merge path and never clobber
per-agent headers.
A catalog on <CopilotKit a2ui={{ catalog }}> is now enough to use A2UI
end to end. Previously developers also had to set a2ui.injectA2UITool: true
on the runtime.
The provider forwards an a2uiCatalogAvailable signal per run whenever it has
a catalog (and renders surfaces locally). handle-run reads that signal and
hands it to configureAgentForRequest, which enables A2UIMiddleware and defaults
injectA2UITool to true. An explicit injectA2UITool value (including false) and
an explicit a2ui.enabled: false are always respected via ?? / short-circuit, so
this only fills the default and never overrides a deeper opt-out.
