## Problem
`resolveModel()` builds each provider with only an `apiKey`, so a
**string model spec** (e.g. `"openai/gpt-4o-mini"`) cannot target an
**OpenAI-compatible endpoint** — Azure OpenAI, OpenRouter, an LLM
gateway, or a local server (vLLM / LM Studio / Ollama).
`OPENAI_BASE_URL` is silently ignored, and the only workaround is to
drop the ergonomic string form and construct a `LanguageModel` instance
yourself. The same gap exists for Anthropic and Google.
## Fix
`resolveModel` now passes `baseURL` from the standard env var for each
provider:
| Provider | Env var |
|---|---|
| OpenAI | `OPENAI_BASE_URL` |
| Anthropic | `ANTHROPIC_BASE_URL` |
| Google | `GOOGLE_GENERATIVE_AI_BASE_URL` |
It is `undefined` when the var is unset, so each provider falls back to
its default endpoint — **fully backward compatible** (no behavior change
unless you opt in).
## Tests
Adds `resolve-model-baseurl.test.ts` (4 cases): each provider forwards
its env var to the SDK factory, and an unset var leaves `baseURL`
undefined. All existing `resolveModel` tests pass unchanged (118 runtime
tests green locally).
## Context
Found while building an OpenAI-compatible agent on the V2 runtime +
`@copilotkit/react-native`, where the string model form couldn't reach
the configured endpoint.

## What does this PR do?
Fixes the mobile CopilotChat v2 textarea caret jump by avoiding repeated
destructive input measurements after textarea sizing measurements are
already
warm.
On mobile viewports, `evaluateLayout` always expands the input. It was
also
calling `ensureMeasurements()` on every evaluation, and that helper
temporarily assigns `textarea.value = ""` before restoring the value.
This can
move the browser selection to the end while typing in the middle of the
input.
`adjustTextareaHeight()` already lazily calls `ensureMeasurements()`
when the
measurement cache is empty, so the mobile branch can rely on that
existing path
without re-measuring on every keystroke.
This PR also adds a regression test that mocks the mobile viewport and
verifies
that warm mobile re-evaluation no longer assigns an empty string to the
textarea value.

## What does this PR do?
Fixes credential forwarding for `ProxiedCopilotRuntimeAgent` on the
default
REST/auto transport.
The single-route transport already adds `this.credentials` to its
`RequestInit`, but the REST `run` and `connect` paths rely on
`HttpAgent.requestInit(input)`. That base initializer does not know
about the
proxy agent's `credentials` property, so cross-origin runtime requests
fall
back to the browser default and drop cookie auth.
This PR overrides `requestInit()` on `ProxiedCopilotRuntimeAgent`,
preserves the
base request init, and adds `credentials` when configured. The existing
transport matrix tests now assert that both `run` and `connect` requests
include
`credentials: "include"` for REST and single-route transports.

## Summary
**Plan C: channels are an Intelligence capability.** A valid
Intelligence configuration (API key) is required to run any channel.
There's a **free tier**, so this is "connect your account," not "pay."
The Intelligence runtime runs every channel: managed (Slack/Teams) over
the gateway, and **direct-adapter** channels (Discord/Telegram/WhatsApp,
or self-hosted Slack/Teams) via their own credentialed transport,
started by the runtime. The SSE runtime type-rejects `channels`, and the
handler builds channel activation for an Intelligence runtime.
> Note: the `channel.ɵruntime.{start,stop,addAdapter}` seam is an
internal (`ɵ`) contract the runtime and the managed launcher drive — not
a public API.
Design doc: [Channels = Intelligence-only (Plan
C)](https://app.notion.com/p/3a63aa381852814e83dafedc0742e7cc)
## What changed
- **`refactor(channels-core)`** — relocate the `Channel` lifecycle onto
an internal `channel.ɵruntime.{start,stop,addAdapter}` seam.
- **`feat(channels-core)!`** — **remove** public
`Channel.start()/stop()/addAdapter()`. Channels are runtime-driven only.
- **`feat(runtime)!`** — the `ChannelManager` (built only for an
Intelligence runtime) now **starts direct-adapter channels** via
`ɵruntime.start()` instead of recording them `"unmanaged"` and skipping.
Dead `"unmanaged"` status removed. Direct channels reuse the same
bounded/idempotent/resilient teardown via a synthetic handle.
- **`fix(channels-core)`** — a channel whose adapters **all** fail to
start now **errors** instead of falsely reporting `online` (a partial
start, ≥1 adapter live, still counts as started).
- **`fix(examples)`** — examples bound `channels.ready({ timeoutMs })`
so a wedged adapter start can't hang readiness.
- **`docs`** — 7 channels READMEs + the teams/slack examples reworked to
`new CopilotRuntime({ intelligence, channels })` +
`handler.channels.ready()/stop()`; no `channel.start()`, no DIY.
Multi-platform slack now runs under Intelligence (one `ɵruntime.start()`
starts all its direct adapters).
**Breaking:** `Channel.start()/stop()/addAdapter()` removed
(`channels-core` 0.2.x) — channels are driven by the runtime (`new
CopilotRuntime({ intelligence, channels })`).
## Validation
**Unit** (per-package raw `tsc` + `vitest`): channels-core **156**,
channels-intelligence **182**, runtime channel-manager **38** (incl. a
new `failStart` regression test), channels-integration 8.
**Independent whole-branch review:** direct-channel lifecycle traced
correct for every start/stop interleaving (no wedge, single-stop,
bounded/idempotent teardown shared with the managed path); public-API
removal complete (zero callers); no DIY/`channelRunner`/guard-relaxation
debris; SSE guard intact.
**Adversarial review** (tried to break it) surfaced two real items, both
handled here:
- **False `online`** — `ɵruntime.start()` swallowed adapter start
failures and resolved, so a dead channel read `online`. **Fixed**
(`fix(channels-core)` + `failStart` test).
- **Overstated invariant** — "no standalone path" is enforced by the
runtime gate + `ɵ` convention, not the type system. **Clarified** (see
the note above). Also bounded example `ready()` (`fix(examples)`).
**Live run** against a real Intelligence key (**7/7**): the gate rejects
channels-without-Intelligence; the runtime starts a direct channel via
`ɵruntime.start()` (a real turn invoked the agent, clean `stop()`); and
the real key **authenticated against the real gateway** (a managed join
was rejected by a project feature-flag, not an auth error — so the key
was accepted).
> Examples typecheck only in CI — the worktree can't build every
`@copilotkit/*` sibling; those `TS2307`/`TS2305` are environmental.

## What
Widens the optional `@anthropic-ai/sdk` peer dependency of
`@copilotkit/runtime` from `^0.57.0` to `>=0.57.0`.
## Why
An outside contributor reported that `@copilotkit/runtime` still
declares an optional peer of `@anthropic-ai/sdk@^0.57.0`, which
conflicts with current SDK versions (e.g. `0.109`) and forces consumers
to install with `--legacy-peer-deps`.
The `^0.57.0` caret pins the range within `0.57.x` (since it's a `0.x`
version), so any newer minor trips the peer-conflict warning even though
the SDK works fine at runtime.
## Safety
The anthropic adapter only relies on stable `@anthropic-ai/sdk` APIs —
client construction (`new Anthropic({})`), `messages.create`, and
ephemeral `cache_control` — which have been stable across `0.x`
releases. The reporter confirms `0.109` works at runtime today; this
only removes the false install-time peer conflict.
## Change
One line in `packages/runtime/package.json`:
```diff
- "@anthropic-ai/sdk": "^0.57.0",
+ "@anthropic-ai/sdk": ">=0.57.0",
```
Channels require an Intelligence connection (API key, free tier); run via
CopilotRuntime({ intelligence, channels }) + handler.channels.ready()/stop();
no channel.start(), no standalone/DIY path. Adapters keep their credentials.

The ChannelManager (only constructed for an Intelligence runtime) now STARTS
direct-adapter channels via channel.ɵruntime.start() instead of recording them
"unmanaged" and skipping — so every channel runs only because Intelligence is
configured; there is no standalone path. Removed the now-dead "unmanaged" status;
direct channels reuse the bounded/idempotent teardown via a synthetic handle.

Channels run only through the Intelligence runtime now; there is no public

## Summary
Fixes#4819.
`processAgentResult` recurses into `runAgent` whenever `needsFollowUp`
is true, with **no depth limit, no circuit breaker, no duplicate
detection**. Any scenario that keeps `needsFollowUp = true` loops
forever:
- The LLM repeatedly calling the same tool
- The backend returning a `RunError` after receiving tool results
(#2416)
- Input processors reprocessing tool messages (#3044)
This silently consumes API quota and can DOS the backend. The only
existing workaround — setting `followUp: false` on a tool — is too blunt
and breaks legitimate multi-step workflows.
## Change
- Add an absolute safety cap `MAX_FOLLOW_UP_DEPTH = 100`, reusing the
existing `_runDepth` counter (incremented in `runAgent`, decremented in
its `finally`).
- In `processAgentResult`, when the depth cap is reached: stop
recursing, emit a `logger.warn` (for debuggability), and return the
current result normally (already-inserted tool messages are preserved).
- The cap is deliberately high so legitimate multi-step workflows
(search → fill form → confirm → update → send email) are never affected;
it only trips on runaway recursion.
This protects against **all** infinite-loop scenarios in the issue, not
just specific triggers, without requiring users to set `followUp:
false`.
## Test
- Added `core-full.test.ts` TEST 9b: an agent that always returns a
fresh tool call (so `needsFollowUp` stays true). Asserts the run
terminates, `runAgent` is capped at ≤100 calls, and a warning is
emitted.
- `nx run @copilotkit/core:test` → 40 files / 431 tests pass.
- `nx run @copilotkit/core:build` → success.
Move start/stop/addAdapter/provider bodies onto channel.ɵruntime.*; the public

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
A frontend/client tool (`useFrontendTool`) whose Zod `parameters` use
`z.discriminatedUnion(...)` — or any schema that serializes to a JSON-schema
`anyOf`/`oneOf` node — silently lost the union-typed field when calling OpenAI.
The tool call arrived with that field missing or empty.
Root cause: the runtime has two JSON-Schema -> Zod converters. The shared one
(`@copilotkit/shared`) already handles `anyOf`/`oneOf` as `z.union`, but the
local copy in `packages/runtime/src/agent/index.ts` — used by the classic
`BuiltInAgent` / AI SDK path via `convertToolsToVercelAITools` — never did.
A union node carries no top-level `type`, so it hit the empty-schema guard and
collapsed to `z.object({})`. The reconstructed tool schema therefore dropped
the union entirely (most visibly for a union nested inside array `items`), so
the model was never offered those fields and could not emit them.
Fix: handle `anyOf`/`oneOf` as `z.union` before the empty-schema guard,
mirroring the shared converter. A single-variant union unwraps to that variant.
Backward compatible: only previously-broken union nodes change behavior
(empty object -> real union). Empty `{}` schemas, typed nodes, and the
`isJsonSchema` gate are untouched.
Repro: a `useFrontendTool` with `parameters: z.object({ blocks: z.array(
z.discriminatedUnion("type", [...])) })` against OpenAI — before, `blocks`
items arrived empty; after, both variants survive into the model call.

The `@copilotkit/react-native` barrel statically re-exports the prebuilt chat
UI (CopilotChat / CopilotModal / CopilotSidebar / CopilotPopup, which import
`@gorhom/bottom-sheet`) and `useAttachments` (which imports
`expo-document-picker` + `expo-file-system`). Those are optional peer deps, but
a static re-export still forces Metro to resolve them at bundle time. A headless
consumer that uses only `CopilotKitProvider` + `useAgent` + `useFrontendTool`
(a fully custom UI) had to install every chat/attachment native dep or stub them
in `metro.config.js`, or the release bundle fails with
`Unable to resolve module expo-document-picker`.
Add a lean `@copilotkit/react-native/headless` entry that re-exports only the
provider, the platform-agnostic hooks, the render-tool registry, and the
core/AG-UI types — none of the chat UI or `useAttachments` — so those native
deps never enter the bundle graph and the metro-stub workaround is retired.
Mirrors `@copilotkit/react-core/v2/headless` (#5883): a standalone entry file,
wired into the tsdown entry list, the package.json `exports` map, and
`sideEffects` (it side-effect-imports the polyfills). The default barrel now
does `export * from "./headless"` and layers the chat UI on top, so it stays
fully backward compatible. Adds a static import-graph regression test asserting
the headless graph never reaches the chat/attachment modules or their native
peer deps.

UseAgentProps had no `threadId`, yet the shipped V2 React Native demo
calls `useAgent({ agentId: "default", threadId })`. Because the prop
didn't exist, it was silently dropped: the demo's thread state (and its
"New Chat" reset) never reached the agent, which ran under its own
auto-minted UUID. threadId was only ever sourced from a surrounding
`CopilotChatConfigurationProvider`, which the headless RN demo has none.
Accept an optional `threadId` on UseAgentProps and honor it. Resolution
precedence: an explicit `threadId` prop wins; otherwise fall back to the
chat configuration's threadId (gated on hasExplicitThreadId, as before).
When the prop is omitted, behavior is unchanged — fully backward
compatible. This makes the RN demo's existing usage work and unblocks
headless callers that have no chat-configuration provider in the tree.
Extends the threadId-propagation contract test with coverage for the
prop path (no provider, prop-over-config precedence, prop re-sync).

resolveModel() built each provider with only an apiKey, so a string model
spec (e.g. "openai/gpt-4o-mini") could not target an OpenAI-compatible
endpoint — OPENAI_BASE_URL was silently ignored, and the only workaround was
to construct the LanguageModel yourself and pass the instance. Same gap for
Anthropic and Google.
Now resolveModel passes baseURL from the standard env var
(OPENAI_BASE_URL / ANTHROPIC_BASE_URL / GOOGLE_GENERATIVE_AI_BASE_URL). It is
undefined when unset, so the provider falls back to its default endpoint —
fully backward compatible.
Tests: adds resolve-model-baseurl.test.ts (4 cases). Existing resolveModel
tests unchanged (118 runtime tests pass locally).
Discovered while building an OpenAI-compatible agent on the V2 runtime +

## What & why
`@copilotkit/react-core`'s `/v2` entry (and the root entry) re-exports
from a
single **monolithic shared chunk**, so importing *any* symbol — even one
hook —
pulls the built-in chat-message rendering stack (`streamdown` → shiki,
`mermaid`,
`cytoscape`, `katex`) into the consumer's bundle: **~3 MB gzip / ~15 MB
raw**,
with no way to tree-shake it. Consumers who build a fully custom chat UI
and only
use hooks pay the full cost. (Issue #4893.)
A separate lean build entry — `@copilotkit/react-core/v2/headless` —
already
ships those hooks in their own small chunk **without** that stack (it's
how
`@copilotkit/react-native` mounts CopilotKit). This PR makes it usable
for a
custom web UI.
Measured with esbuild (react/react-dom external):
| import | bundled JS |
|---|---|
| hooks from `@copilotkit/react-core/v2` | **~2.96 MB** gzip (≈
importing full `CopilotChat`) |
| same hooks from `@copilotkit/react-core/v2/headless` | **~0.03 MB**
gzip |
> Note on the report: `@copilotkit/a2ui-renderer` doesn't bundle the
rich-text
> stack (its deps are `@a2ui/web_core`, `lit`, `clsx`, `zod`). The
weight is
> entirely `streamdown` (shiki/mermaid/cytoscape) + `katex`, pulled by
the
> built-in `CopilotChat*` message components.
## Changes
- **`headless.ts`** — export `useCopilotKit` + `useRenderToolCall` (both
DOM-free
and rendering-stack-free); fix `UseAgentUpdate` (a runtime `enum`) being
re-exported via `export type`, which stripped its runtime value under
`isolatedModules` (so `useAgent`'s `updates` option was unusable from
headless
— a bug `tsc` can't catch). `useDefaultRenderTool` /
`useRenderCustomMessages`
/ `useRenderActivityMessage` stay in `/v2` (web-only markup or
`a2ui-renderer`).
- **Remove a `tailwind-merge` leak** — extract the tailwind-free ref
helpers
(`shallowEqual` / `useShallowStableRef`) into
`lib/shallow-stable-ref.ts` so the
headless graph no longer pulls `tailwind-merge` via
`CopilotChatConfigurationProvider`.
- **Test** — a small vitest export-surface test guarding the hook
surface and the
`UseAgentUpdate` runtime value.
## Verification
`react-core` typecheck + vitest (1427) and `react-native` typecheck
pass. Shipped
`dist/v2/headless.mjs` imports only `react`, `@ag-ui/client`,
`@copilotkit/core`,
`@copilotkit/shared`, `@copilotkit/react-core/v2/context`, `zod` — no
rendering
stack.
## Notes / follow-ups
- Headless hooks read a **different React context** than the prebuilt
`/v2`
`<CopilotKitProvider>`, so the two can't be mixed — mount a lean
provider over
`/v2/context` (as `@copilotkit/react-native` does). Making the `/v2`
provider
reuse the standalone `/v2/context` singleton would remove that sharp
edge and
is the natural follow-up.
- Existing bundle-size CI (`compressed-size-action`) already tracks
`headless.mjs`,
so no new size tooling is added here.

Fixes#5966. Follow-up to #5812 / #5885.
## Problem
After #5885 stopped the post-terminal `TEXT_MESSAGE_END` crash, pressing
**Stop** no longer breaks the chat — but for an agent that emits a
terminal `RUN_ERROR` (code `abort`) as its cancellation signal (e.g.
pydantic-ai's `AGUIAdapter`), the client still surfaces that as an
**error banner** ("This operation was aborted"). A user-initiated stop
is expected cancellation, not a failure.
Traced path (no abort suppression at any hop):
`RUN_ERROR(code:"abort")` → `RunHandler.onRunErrorEvent`
(`run-handler.ts`) → `emitAgentError(AGENT_RUN_ERROR_EVENT)` → `onError`
→ CopilotChat/react-ui `triggerChatError` → banner. The only existing
abort suppression is for the *local* fetch-abort rejection
(`run-handler.ts:318`), a different path.
## Fix
Suppress the error emission in `onRunErrorEvent` when the run was
user-aborted — mirroring the local-abort suppression already on the
`runAgent`/`connectAgent` paths:
```ts
const runWasAborted = this._runAbortController?.signal.aborted === true;
if (runWasAborted || event?.code === "abort") {
return;
}
```
Prefers the client's own `_runAbortController.signal.aborted` (robust —
the agent-supplied `code` isn't standardized across agents; the
`code:"abort"` in the repro comes from the agent, not CopilotKit) with
`code === "abort"` as a secondary signal. Normal `RUN_ERROR`s are
unaffected.
## Testing
- **TDD** (`core-error-handling.test.ts`): two new tests fail pre-fix
and pass after —
- agent emits `RUN_ERROR` code `"abort"` → no `AGENT_RUN_ERROR_EVENT`
surfaced.
- run user-aborted mid-stream (via `agent.abortRun()`, which RunHandler
intercepts to abort the controller) → a subsequent `RUN_ERROR` with a
*non-abort* code is still suppressed (exercises the `signal.aborted`
path).
- The pre-existing test — normal `RUN_ERROR` (code `"bad_request"`)
still emits `AGENT_RUN_ERROR_EVENT` — continues to pass (control against
over-suppression).
- Full `@copilotkit/core` suite green: **578/578**. `tsc` 0 errors;
`oxlint` 0.
Note: this is a UX/product call (a user Stop shouldn't render as an
error). Suppressing in core fixes it for both the default chat banner
and app-level `onError` handlers; the run lifecycle still reflects the
termination.

The optional peer dependency on @anthropic-ai/sdk was pinned to
^0.57.0, which conflicts with current SDK versions (e.g. 0.109) and
forces consumers to install @copilotkit/runtime with --legacy-peer-deps.
The anthropic adapter only relies on stable @anthropic-ai/sdk APIs
(client construction, messages.create, ephemeral cache_control), so
loosen the range to >=0.57.0 to remove the false peer conflict.
pnpm auto-installs this optional peer, so its specifier is mirrored in
the lockfile; update that specifier line to match. The resolved version

and `pnpm install --frozen-lockfile` passes.

## Summary
`CopilotChatInput`'s `AddMenuButton` renders its trigger as nested Radix
`asChild` slots:
```tsx
<TooltipTrigger asChild>
<DropdownMenuTrigger asChild>{button}</DropdownMenuTrigger>
</TooltipTrigger>
```
Radix `asChild` slots forward a ref to their child.
`DropdownMenuTrigger` and `TooltipTrigger` were plain function
components, so under React 18.3 the forwarded ref triggers this warning
on every render (reported in #5744):
```
Warning: Function components cannot be given refs. Attempts to access this ref will fail.
Did you mean to use React.forwardRef()?
```
## Change
Wrap `DropdownMenuTrigger` and `TooltipTrigger` in `React.forwardRef`,
forwarding the ref to the underlying Radix primitive — mirroring
`forwardRef` usage already present in this package (e.g. `Button`,
`CopilotChatInput.TextArea`). No behavior change; the ref now reaches a
DOM node and the warning is gone.
## Scope
Limited to the two primitives in the reported warning path. The other
shadcn/ui primitives in `react-core` follow the same React-19
(no-`forwardRef`) style and would warn identically when used as
`asChild` children under React 18.3 — happy to extend this to the rest
if you'd prefer full React 18.3 coverage.
## Verification
- `nx build @copilotkit/react-core` succeeds (compiles source +
generates type declarations).
- Pre-commit `test-and-check-packages` passes.
Fixes#5744
## What does this PR do?
- Preserve non-tool `AIMessage` fields when frontend tool calls are
intercepted in `afterModel` and restored in `afterAgent`, including
`additional_kwargs`, `response_metadata`, `usage_metadata`,
`invalid_tool_calls`, `id`, and `name`.
- Use a shared rebuild helper with `tool_calls` as the source of truth.
For LangChain v1 content blocks, remove stale `tool_call` and
`tool_call_chunk` blocks before reconstructing the message.
- Add regression coverage for the `reasoning + backend/frontend tool
calls -> afterModel -> afterAgent` flow, including metadata preservation
and v1 content block synchronization.

Adds the opt-in secondary entry point @copilotkit/angular/mcp-apps for
rendering MCP Apps (MCP ext-apps) inline in the chat:
- CopilotMCPAppsActivityRenderer plus a ready-to-register
mcpAppsActivityRendererConfig for activityType mcp-apps
- CopilotMCPAppsWidget loads the app's ui:// resource from the configured
MCP server, embeds it in a sandboxed iframe, and connects an AppBridge
that relays tool input/result, size changes, links, and log messages
- provideMCPApps registers server URLs and the host identity, capabilities,
and context announced to embedded apps
- @modelcontextprotocol/sdk and @modelcontextprotocol/ext-apps are optional
peer dependencies; the main entry point stays free of MCP imports

## What does this PR do?
Fixes a Vue `DataCloneError` that occurred when uploaded attachment
sources crossed the `structuredClone` boundary in core. Vue’s deep
`ref()` conversion wrapped nested attachment sources in reactive
proxies; `useAttachments` now keeps the attachment container shallow
with `shallowRef()`, preserving externally supplied sources as raw
cloneable values before they reach AG-UI/core payloads.
The change is intentionally Vue-only: core and React are untouched
because the defect is caused by Vue’s reactivity behavior at the
framework boundary. Focused regressions cover both the attachment hook
and `CopilotChat` submission path, including non-reactivity and
successful `structuredClone` behavior.

Fixes#2596
## Summary
`@copilotkit/runtime-client-gql` was still assuming abort-shaped errors
always expose a string `message`, which could turn an early-stop path
into a secondary TypeError instead of a clean abort suppression or the
original failure. This branch centralizes abort detection behind a
null-safe helper and keeps the existing abort phrases unchanged.
## Changes
- Replaced the duplicated abort checks in
`packages/runtime-client-gql/src/client/CopilotRuntimeClient.ts` with a
shared `isAbortError(unknown)` helper that only inspects string
messages.
- Added focused regression coverage in
`packages/runtime-client-gql/src/client/__tests__/CopilotRuntimeClient.test.ts`
for a string abort cause, an object without `message`, known abort
suppression in the stream path, and non-abort stream errors surfacing
normally.
- Added `.changeset/guard-abort-error-message.md` for the patch release
note.
## Scope
Only `packages/runtime-client-gql` and its local changeset are touched.
The abort phrases, caller-facing API, structured GraphQL error handling,
and stream close behavior for known aborts are unchanged.
## Test Plan
- [x] `npx nx run @copilotkit/runtime-client-gql:graphql-codegen` -
regenerated the package GraphQL artifacts used by the client imports.
- [x] `pnpm run build` - workspace build completed successfully.
- [x] `pnpm -C packages/runtime-client-gql exec vitest run
src/client/__tests__/CopilotRuntimeClient.test.ts` - 4/4 passed. Covers
a string abort cause in the fetch path, an object with no `message` in
the fetch path, known abort suppression in the stream path, and
non-abort stream errors surfacing.
- [x] `pnpm exec oxfmt --write
packages/runtime-client-gql/src/client/CopilotRuntimeClient.ts
packages/runtime-client-gql/src/client/__tests__/CopilotRuntimeClient.test.ts`
- formatted the touched source and test files.
- [x] `pnpm exec oxlint
packages/runtime-client-gql/src/client/CopilotRuntimeClient.ts
packages/runtime-client-gql/src/client/__tests__/CopilotRuntimeClient.test.ts`
- 0 warnings, 0 errors.
`useAgent` always returns a fully-constructed `AbstractAgent`: a provisional
stand-in while the runtime is still connecting (or in an error state), swapped
for the real agent once the `/info` sync resolves. The returned type claimed
`agent` was always the real agent, giving consumers no way to tell the two
apart — so one-time subscriptions (e.g. `onRunFinalized`) registered during the
provisional window landed on the placeholder and missed events until the effect
re-ran after the swap.
Add an `isReady` flag to the return value: `false` while the agent is
provisional, `true` once the real (or locally-registered) agent is bound.
Additive and backward compatible.
Also fix the docs' "Event Subscription" example, which used an empty
`useEffect` dependency array and therefore never re-subscribed when the agent
reference changed.
Note: the original crash from #5000 ("Cannot read properties of undefined
(reading 'subscribers')") no longer reproduces on `main` — the provisional-agent
work (#5533/#5635) guarantees a fully-constructed agent, so `subscribe()` is
always safe. The added tests lock in that no-crash behavior and cover the new
`isReady` transition.

Six pre-existing `@copilotkit/channels-intelligence` HTTP-transport
robustness items surfaced by the pre-merge CR of #5983 (Linear OSS-497).
All confirmed against `main` after #5983 merged; none introduced by it.
Each is an independent, focused commit with a test.
## Fixes
1. **Heartbeat starvation mid-turn** — `HttpDeliverySource.runLoop`
heartbeated only at the top of each iteration, then blocked on
`onDelivery` for up to `turnTimeoutMs` (120s). With a 15s cadence, a
turn longer than the cadence sent no heartbeat, so app-api could mark a
healthily-working runtime stale mid-turn and withhold new deliveries.
Heartbeating now runs on a standalone recurring timer, independent of
the claim loop.
2. **`stop()` shutdown latency** — `stop()` set `running=false` then
awaited the loop, which only rechecked after its current sleep (≤15s
idle) or `onDelivery` (≤120s mid-turn); sleeps were `unref`'d but not
interruptible. Added a `stopWait` promise that the poll-sleep and
turn-wait both race, so shutdown is prompt. A mid-turn stop leaves the
lease for app-api to re-lease and does **not** nack (the turn didn't
fail); the turn's eventual settlement is always handled so a post-stop
rejection never surfaces as unhandled. *(1 & 2 share the runLoop
lifecycle, so they land in one commit.)*
3. **Empty-text `update` silently acked** — the `if (!text) return { ok:
true }` guard ran for both `post` and `update`. An empty POST is a legit
no-op, but an empty UPDATE (e.g. clearing a message body) that this
post-only fallback egress can't express was acked as success. Now
returns `{ ok: false, code: "empty_update" }`; empty posts still no-op.
4. **Static `adapter` on egress** — `emit` posted `this.cfg.adapter`
(default `"slack"`) alongside a possibly-Teams `replyTarget`. Confirmed
app-api's egress route (`sendChannelEgressMessage`) routes on
`replyTarget.adapter` + `channelName` and ignores this field, so it's
latent — but now derived from the delivery's own reply route to avoid
the contradiction. *(Note: the listener heartbeat's
`declaredChannels[].adapter` is intentionally left alone — app-api
genuinely consumes it for per-adapter health/conflict via the
`channel_adapter_configs.provider` join, and declaring the bot's full
adapter set is a separate design change, not a robustness cleanup.)*
5. **`projectId` strict-`number` only** — the realtime scope build
accepted `projectId` only as a JS `number` while org/channel were
`String()`-coerced, so a numeric-string on the untyped wire silently
fell back to the transport-default projectId, defeating per-delivery
scope authority. Extracted a `coerceWireProjectId` helper (number or
numeric-string → positive integer) with fallback.
6. **File/history client ignored injectable `fetch`** —
`fetchFile`/`getHistory`/`uploadFile` hardcoded `globalThis.fetch`, so
an injected `config.fetch` was honored everywhere except
binary/history/upload. The transport's `FetchLike` is text-only and
can't satisfy the binary client, so the file/history client got its
**own** injectable full `fetch` (`typeof fetch`), resolved via a single
helper with a global fallback.
Plus a small `docs` commit fixing a doc-comment placement displaced by
the item-5 export.
## Testing
- `nx run @copilotkit/channels-intelligence:test` — **178 passed** (170
baseline + 8 new).
- `nx run @copilotkit/channels-intelligence:check-types` — clean.
- lefthook (full package test + typecheck) ran on every commit.

Follow-up to the OSS-497 robustness cluster after a 3-agent adversarial review.
- Empty-text update: reclassify from a hard {ok:false} failure to a logged
no-op. The failure path threw up the run and nack'd the WHOLE turn retryably,
re-running valid work to dead-letter for a condition a retry can't fix (an
agent clearing a message body the post-only fallback can't express). Now it is
skipped with a distinct warning log — surfaced, not silent, and not turn-fatal.
- Injectable fetch: plumb it through the transports. Both HttpDeliverySource and
RealtimeGatewayTransport now accept a binary-capable /
and forward it to IntelligenceFileHistoryClient, so a consumer injecting a
fetch has it honored on the download/history/upload paths (previously the
client-level injectable was reachable only by constructing the client directly).
- coerceWireProjectId: use Number.isSafeInteger so a numeric string beyond
MAX_SAFE_INTEGER is rejected (was silently coerced to a lossy integer).
- Malformed-present projectId: log before falling back to the transport scope
(an absent projectId still falls back quietly), mirroring the loud drops in
the same function instead of silently masking a wire-corruption signal.
- Restart safety: guard the recurring heartbeat with a run generation so a
stop->start while a heartbeat POST is in flight can't leave two reschedule
chains doubling the heartbeat rate; bump the generation on stop().
- Remove now-dead lastHeartbeatAt state (only reader was the removed in-loop
heartbeat check).
Tests: empty-update now asserts log + no-op; added transport fileFetch
wire-through, adapter-from-route fallback, no-unhandled-rejection after a
mid-turn stop, heartbeat-stops-after-stop, elapsed-time bounds on the stop()
promptness tests, and coerceWireProjectId edge cases (leading zeros, > safe int).
nx test (green) + check-types (clean).
The coerceWireProjectId export (added for OSS-497) was inserted directly above
assertValidChannelRealtimeScope, displacing that function's doc comment onto the
helper. Reorder so each function carries its own docblock.
IntelligenceFileHistoryConfig's fetchFile/getHistory/uploadFile hardcoded
globalThis.fetch, so a consumer (or test) injecting a fetch had it honored
everywhere EXCEPT the binary download, history, and upload paths. The transport's
FetchLike is text-only ({ ok, status, text() }) and cannot satisfy the binary
client (.body/.arrayBuffer()/.headers/.json()), so add the client's OWN
injectable full `fetch` (typeof fetch) on its config, resolved via a single
resolveFetch() helper that falls back to the global fetch. Each caller keeps its
existing degrade/throw contract for the no-fetch runtime.
Surfaced by the pre-merge CR of #5983 (OSS-497).
Two coupled HttpDeliverySource runLoop lifecycle robustness fixes:
Heartbeat starvation: the loop heartbeated only at the top of each iteration,
then blocked on onDelivery for up to turnTimeoutMs (120s). With a 15s cadence,
a turn longer than the cadence sent no heartbeat for its whole duration, so
app-api could expire the activation and mark a healthily-working runtime stale
mid-turn, withholding new deliveries. Move heartbeating to a standalone
recurring timer that fires on cadence regardless of what the loop is doing
(rescheduling only after each heartbeat settles, so no overlap).
Shutdown latency: stop() set running=false then awaited the loop, but the loop
only rechecked after its current sleep (up to cadence, idle) or onDelivery (up
to turnTimeoutMs, mid-turn) — the sleeps were unref'd but not interruptible, so
shutdown could take up to 15s idle or 120s mid-turn. Add a stopWait promise that
stop() resolves; the poll-sleep and the turn-wait both race it, so shutdown is
prompt. A mid-turn stop leaves the lease for app-api to re-lease and does NOT
nack (the turn didn't fail); the turn's eventual settlement is always handled so
a post-stop rejection never surfaces as unhandled.
Surfaced by the pre-merge CR of #5983 (OSS-497).
RealtimeGatewayTransport.toIngressEnvelope built the per-delivery scope with
`typeof delivery.projectId === 'number' ? delivery.projectId : this.scope.projectId`,
while organizationId/channelId were String()-coerced. The delivery.available
payload is untyped JSON, so a numeric-string projectId ('9' on the wire) failed
the strict check and silently substituted the transport-default projectId —
defeating the per-delivery scope authority and routing the render-accept under
the wrong project.
Extract a `coerceWireProjectId` helper (number or numeric-string -> positive
integer, else undefined) and use it with a fallback to the transport default.
Surfaced by the pre-merge CR of #5983 (OSS-497).
HttpEgressSink.emit posted the static `this.cfg.adapter` (default "slack")
alongside a possibly-Teams `replyTarget`, so a Teams delivery through the
fallback egress carried a contradictory `adapter: "slack"`. app-api's egress
route (sendChannelEgressMessage) routes on `replyTarget.adapter` + channelName
and ignores this top-level field, so this is latent — but one provider-agnostic
runtime serves every adapter its bot has attached, so posting the config default
is misleading. Derive the posted adapter from the delivery's own reply route,
falling back to the config adapter when the route carries none.
Note: the listener heartbeat's declaredChannels[].adapter is NOT changed here —
app-api genuinely consumes it (the channel_adapter_configs.provider join) for
per-adapter health/conflict reporting, and the runtime only knows its single
configured adapter; declaring the bot's full adapter set is a separate design
change, not this robustness cleanup.
Surfaced by the pre-merge CR of #5983 (OSS-497).
