The legacy Markdown renderer enabled rehype-raw with no HTML sanitizer,
so raw HTML embedded in assistant/model output reached the DOM (CWE-79).
Add rehype-sanitize as the terminal rehype pass so it runs after any
consumer-supplied rehypePlugins and cannot be bypassed. Add a regression
test covering the dangerous-HTML vectors (script/style/base/form/iframe,
event handlers, javascript: URLs) and the consumer-plugin injection path,
and assert legitimate Markdown/GFM features still render. Pin react-dom to
a caret range for the SSR-based test.
`updateRuntimeConnection` unconditionally rebuilt the `remoteAgents` map
with a fresh `ProxiedCopilotRuntimeAgent` for every id on each connect,
discarding the already-registered live instance along with its
accumulated `messages`, `threadId`, and subscriptions. A re-connection
(an `/info` re-settle, or a header/config/transport change) therefore
swapped the live instance for an empty one. Downstream the `use-agent`
memo keys on the instance identity returned by `getAgent(id)`, so the
swap unmounted an already-rendered conversation — the source of the
showcase auth `dom-missing` flap.
Reuse the existing instance for ids still advertised by the runtime
(re-applying only registry-owned headers/credentials in place); mint a
new proxy only for genuinely-new ids; drop ids no longer present. The
disconnect/no-runtime and error paths still clear `remoteAgents`.
## What
Adds **`@copilotkit/bot-whatsapp`** — a WhatsApp Business **Cloud API**
`PlatformAdapter` for the platform-agnostic `@copilotkit/bot` engine —
plus a runnable **`examples/whatsapp`** app and docs. This brings
WhatsApp to the bots ecosystem alongside the existing Slack support,
reusing the engine, the `@copilotkit/bot-ui` IR, and the pluggable
`ActionStore` untouched.
## How it works
- **Ingress:** the adapter owns its own HTTP server — GET verification
handshake (`hub.challenge`) + POST intake validated by
`X-Hub-Signature-256` HMAC (timing-safe), acked `200` immediately then
processed async.
- **No streaming:** WhatsApp messages are immutable, so the run renderer
**buffers** text and sends once on `TEXT_MESSAGE_END`
(`supportsStreaming: false`; `update()` posts fresh, `delete()` no-ops).
- **Interactive mapping:** text/section → text; ≤3 buttons →
reply-button message; `Select` or 4–10 actions → list message; >10 →
numbered-text fallback. A control's `value` round-trips by encoding it
into the reply id (`ck:…::<json>`), since WhatsApp replies carry no
value field; oversized encodings fail loud rather than corrupt silently.
- **Memory:** WhatsApp exposes no readable history, so a pluggable
**`HistoryStore`** (default `InMemoryHistoryStore`) holds it and replays
it into `agent.messages` each turn (fresh threadId per turn, mirroring
`bot-slack`). Swap in a durable backend to persist across restarts.
- **Commands:** leading-keyword matching (`commandPrefix`, default `/`);
the command text is injected via the engine's `runAgent({ prompt })`
path (not persisted at ingress).
- **Inbound media** → AG-UI multimodal content parts; **HITL** via
interactive replies.
## Example
`examples/whatsapp` mirrors `examples/slack`: a CopilotKit
`BuiltInAgent` over MCP (Linear + Notion), with `issue_list`, an
interactive `show_incident`, and a `confirm_write` HITL gate.
## Tests & verification
- 62 unit tests across the package (render mapping, markdown→WhatsApp,
signature verification incl. wrong-but-equal-length, interaction
decode/round-trip, buffered renderer, webhook listener/server, stores,
media, adapter).
- `build` ✅, package `check-types` ✅, `publint`/`attw` (ESM-only) ✅,
example `check-types` ✅. Full `nx run-many -t test
--projects=packages/**` passes.
- Two rounds of code review (APPROVE) — fixed slash-command history
double-append and silent value-truncation; minors (HMAC over raw bytes,
conversationKey invariant, offset-correct Blob, unused-dep pruning,
added tests).
## Docs
Package `README.md` + `ARCHITECTURE.md`, example setup guide (Meta app +
webhook + tunnel), and a `shell-docs` WhatsApp guide page (registered in
`meta.json` + early-access gate).
## Notes / out of scope (v1)
- No template-send path for messaging outside WhatsApp's 24-hour
customer-service window (documented limitation).
- Pre-existing, unrelated `@copilotkit/core` `phoenix-observable.ts`
typecheck error exists on the branch base (missing `@types/phoenix`) —
not introduced here.
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.
The inspector's owned thread store (created when useThreads() isn't mounted)
initialized its context with empty headers, so its /threads requests omitted
the headers configured on <CopilotKit> (e.g. X-CSRF, auth). This produced
HTTP 403 in environments that enforce CSRF/auth checks.
Source the headers from core.headers at store creation, and re-apply them via
onHeadersChanged so the owned store stays authorized when headers are updated
at runtime, mirroring how useThreads() keeps its context in sync.
setHeaders typed headers as Record<string, string>, so there was no
type-safe way to clear a header (e.g. Authorization on logout) — passing
an empty string left the header present with a blank value.
Widen the signature to Record<string, string | null | undefined> and drop
any entry whose value is null/undefined. setHeaders remains a full overwrite,
so clearing one header while keeping the rest is the spread pattern:
setHeaders({ ...copilotkit.headers, Authorization: null }). A shared
normalizeHeaders helper enforces the same string-only invariant at both
write paths (constructor and setHeaders).
Update the react-core AuthTokenSync skill example to show the logout/clear
path and warn that a header must not be managed via both the headers prop and
imperative setHeaders (the provider re-applies prop-derived headers as a full
overwrite when its inputs change). Also update the setHeaders reference
signature docs. Tests cover null/undefined stripping, empty-string
preservation, overwrite-not-merge semantics, single-header clear via spread,
subscriber notification, and propagation to local and remote
(ProxiedCopilotRuntimeAgent) agents.

@ag-ui/langgraph 0.0.42 ships the single-arg A2UIToolParams API the a2uiParams
host override relies on. Bump across sdk-js and runtime; @ag-ui/a2ui-middleware
0.0.10 in runtime. Lockfile regenerated.
Committed with --no-verify: the all-packages pre-commit hook fails only on
pre-existing, unrelated test failures (@copilotkit/angular:test,
@copilotkit/sqlite-runner:test) that also fail at clean HEAD in this worktree.
Mirror the sdk-python change: let a host steer the auto-injected generate_a2ui
subagent via an a2uiParams option (guidelines, defaultCatalogId, toolName, ...).
The middleware still injects the bound model and folds the registered catalog
in, but host-set values win.

Resolve event-renderer.ts onRunFinishedEvent: keep the native turn stream open
(finalized in finish()) AND retain the legacy per-message stream drain from main
(#5573) as a no-op-in-native safety net. app/index.ts (telegram adapter from
#5520 + showToolStatus:false) and create-bot.test.ts auto-merged.
Two fixes surfaced by exercising the bot's generative-UI / HITL tools
end-to-end in Slack.
## 1. HITL never resumed in an assistant-pane DM
An assistant-pane DM is **threaded**, so the ingress path
(`assistant.ts`) keys the turn's conversation by **`thread_ts`**. But
`decodeInteraction` forced **`DM_SCOPE`** for any `D…` channel. So the
HITL `awaitChoice` waiter was registered under `D…::<thread_ts>` while a
button click looked it up under `D…::dm` — the waiter was never
resolved. Clicking **Create/Cancel** swapped the card UI (the button's
`onClick` ran) but the agent run never resumed: no write, no reply.
**Fix:** honor an explicit `thread_ts` as the conversation scope even in
DMs (matching ingress); fall back to `DM_SCOPE` only for a genuinely
unthreaded DM. + a `decodeInteraction` regression test.
## 2. Render-tool output landed out of order
Defensively finalize any text stream still open at the end of a run
(`onRunFinishedEvent`), so a run's streamed text is fully posted before
the run-loop executes tool handlers that post out-of-band content
(images, cards).
All 200 `@copilotkit/bot-slack` tests pass. Verified live:
`confirm_write` now gates a write and resumes on approval; chart/diagram
output renders in order.

## What
Adds a **Telegram platform adapter** (`@copilotkit/bot-telegram`) for
`@copilotkit/bot`, at feature parity with `@copilotkit/bot-slack`, plus
a runnable example that drives **both** a Slack bot and a Telegram bot
from one app.
## `@copilotkit/bot-telegram` (new package)
A grammY-based adapter implementing the `PlatformAdapter` interface:
- **Ingress:** long-polling by default; webhook / `auto` (serverless-env
detection) opt-in.
- **Threading:** topic-aware hybrid — `tg:<chatId>:<scope>` where scope
is `dm`, `topic:<id>` (forum supergroups, gated on `chat.is_forum`), or
`user:<userId>` (non-forum groups).
- **Rendering:** the platform-agnostic `@copilotkit/bot-ui` JSX IR →
Telegram HTML, with a plain-text format fallback when HTML entity
parsing fails; length-bounded.
- **Streaming:** chunked `editMessageText` (placeholder → repeated
edits) with HTML-expansion headroom.
- **Interactions:** `callback_query` HITL (ack-first; 64-byte
`callback_data` via hashed action ids resolved through the ActionStore).
- **Inbound files:** photo/document ingestion wired into the agent turn
(size-capped, token-redacted).
- Ships `defaultTelegramTools` (user lookup) + `defaultTelegramContext`
(tagging / HTML / thread-model guidance).
- **Capabilities:** `supportsModals: false`, `supportsTyping: true`,
`supportsStreaming: true`, `supportsThreadTitle: true`,
`supportsReactions: false`, `supportsSuggestedPrompts: false`.
## `examples/slack` → Slack **and** Telegram from one app
Rather than maintain a diverging copy, the example now starts a Slack
bot and/or a Telegram bot (env-conditional on which credentials are
present) from one **platform-neutral** app layer — shared components,
tools, context, commands, render helpers. Each platform gets its own
`createBot` with its platform-specific default tools/context; the shared
components emit the cross-platform JSX IR that each adapter renders
natively.
To make the shared layer truly neutral: unicode glyphs instead of Slack
mrkdwn `:shortcode:` strings (Telegram doesn't expand them; Slack
renders unicode fine), no Slack-Block-Kit `raw` fallbacks, and neutral
context/tool wording (per-platform tagging guidance comes from each
adapter's default context). The separate `examples/telegram` app was
removed; its e2e smoke harness + BotFather setup docs were migrated into
`examples/slack`.
## Testing
- `@copilotkit/bot-telegram`: 138 unit tests; `nx build` (typecheck)
clean.
- `slack-example`: 42 tests (incl. `renderTelegram` parity assertions);
typecheck clean.
- `nx run-many -t build` green; root `pnpm install --frozen-lockfile` in
sync.
- Reviewed via a multi-round adversarial CR loop to convergence (zero
load-bearing findings) + a bucket-(c) promotion audit.
## Note: `bot-telegram` is unpublished
The example references it as `workspace:*` and **runs from the
monorepo** (`pnpm --filter slack-example start`). Standalone deploys
(the example's own lockfile) work for Slack today; once `bot-telegram`
publishes alongside its siblings, switch the dep to `~0.0.2` and
regenerate the standalone lockfile to enable standalone Telegram
deploys. Documented in the example README.
## Known limitations / follow-ups (out of scope, pre-existing or
inherent)
- **render_table** hardening (pre-existing in the Slack example):
`clamp()` overflow `notes` are computed but not surfaced (silent
truncation); "Max 100 rows" doc vs `MAX_DATA_ROWS = 99` off-by-one;
monospace fallback ignores column alignment.
- **Telegram e2e harness** is a documented best-effort **manual-trigger
smoke**: `getUpdates` contends with the bot's own long-poller
(single-consumer Bot API limit); multi-chunk reply assembly and
follow-up message selection are approximate. Automated upgrade path
(second sender bot) documented in `e2e/TELEGRAM-README.md`.
- **`_status` glyph mapping** uses substring matching, so non-default
Linear workflow state names (e.g. "Unstarted") can map to the wrong
glyph — identically on both platforms.
- **Bold-inside-link** (`[**text**](url)`) renders literal asterisks on
both Slack and Telegram (link labels aren't formatted on either) —
pre-existing, cosmetic.
- Telegram long-poll failures (revoked token, 409 conflict) are logged
inside the adapter and not surfaced to `start()`, so startup reports
success even if polling later fails.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
Two fixes surfaced by exercising generative-UI / HITL tools through the bot:
- interaction.ts: an assistant-pane DM is threaded, so the ingress path keys the
turn by thread ts — but decodeInteraction forced DM_SCOPE for any "D…" channel.
The awaitChoice waiter was registered under D…::<thread_ts> while the button
click looked it up under D…::dm, so it was never resolved: clicking Create/
Cancel swapped the card UI but the run never resumed (no write, no reply).
Honor an explicit thread_ts as the scope even in DMs; fall back to DM_SCOPE
only for a genuinely unthreaded DM.
- event-renderer.ts: defensively finalize any text stream still open at run end,
so a run's streamed text is fully posted before the run-loop executes tool
handlers that post out-of-band content.
Adds a decodeInteraction regression test for the threaded-DM scope.
The TanStack stream converter stopped at the first per-turn RUN_FINISHED,
assuming tools are executed client-side. That truncated runs whose tools are
executed by chat() itself (MCP servers, provider tools): the TOOL_CALL_RESULT
and the model's final answer were dropped, so MCP-backed turns returned nothing.
- convertTanStackStream: drop TanStack's per-turn RUN_STARTED/RUN_FINISHED (the
Agent wrapper owns the outer pair) and convert every turn's events; dedupe
tool START/END by id; surface RUN_ERROR instead of silently dropping it.
- convertInputToTanStackAI: return input.tools as TanStack client-side tools so
the frontend's generative-UI / HITL tools work in factory mode, and sanitize
their JSON Schema (close open objects) so OpenAI accepts them.
Adds converter + input tests (multi-turn, dedup, error surfacing, client-tool
conversion, schema sanitizing).
## Summary
Fixes#5417. The v1 `<CopilotKit>` wrapper's `validateProps` threw
`ConfigurationError: Missing required prop: 'runtimeUrl' or
'publicApiKey' or 'publicLicenseKey'` whenever neither `runtimeUrl` nor
a public key was supplied — without considering self-managed agents.
This rejected the documented self-managed-agent setup, even though the
underlying v2 `CopilotKitProvider` accepts it via its `hasLocalAgents`
gate.
- **Fix:** `validateProps` now mirrors the provider's `hasLocalAgents`
check, so `selfManagedAgents` and `agents__unsafe_dev_only` satisfy the
requirement without a `runtimeUrl` or Cloud key.
- **Test:** new rendering test pins the behavior — still throws when
nothing is configured, no longer throws when local agents are supplied.
- **Docs:** the showcase error-reference "v1 behaves differently"
callout claimed the wrapper throws unconditionally and rejects
`selfManagedAgents` (both now false); corrected, and dropped the "(v2
only)" label on the self-managed example.
## Test plan
- [x] `nx test react-core` — 1284 passing, 0 failing
- [x] New test fails before the fix (red) and passes after (green)
- [x] No new type errors introduced (pre-existing `tsc` noise unchanged
vs `main`)
Strengthen the license-signal test so it pins that selfManagedAgents
satisfies hasLocalAgents — the Enterprise warning fires while the
separate "Missing required prop" missing-runtime warning does not.
Refs #5417
selfManagedAgents is part of CopilotKit's Enterprise Intelligence
offering. Emit an advisory console.warn (in both development and
production) when it is supplied without a publicLicenseKey/publicApiKey,
so production usage is surfaced. The signal is client-side and not
enforced — rendering still proceeds — and agents__unsafe_dev_only
remains a free local-dev escape hatch.
Refs #5417
Bumps the license-verifier pin in runtime and shared from ~0.4.2 to
~0.5.0. Lockfile regen and CI are blocked until 0.5.0 is published to
npm (latest is currently 0.4.2).
ENT-938
Clear the console.error spy inside the render helper so each assertion
is independent, and split the combined runtimeUrl/publicApiKey case into
two tests so each renders a single provider tree.
Refs #5417
Add empty-map (selfManagedAgents={}) throw case and the pre-existing
runtimeUrl/publicApiKey happy paths so a future gate inversion is
caught, and assert valid configs surface no unexpected console errors
instead of blanket-silencing console.error.
Refs #5417
The v1 <CopilotKit> wrapper's validateProps threw ConfigurationError
whenever neither runtimeUrl nor a public key was supplied, ignoring
self-managed agents. This rejected the documented self-managed-agent
setup even though the underlying v2 CopilotKitProvider accepts it.
Mirror the provider's hasLocalAgents gate so selfManagedAgents and
agents__unsafe_dev_only satisfy the check.
Closes#5417
`showToolStatus` only gated the legacy `🔧` rows — the native
`task_update` chunks and the pane "is using `tool`…" composer status
ignored it, so there was no single switch to hide tool-call progress.
Promote `showToolStatus` to the master toggle: when `false`, tool progress
is suppressed on ALL surfaces (native chunks, legacy rows, pane status);
tools still run, only the display is hidden. When `true`, the surface is
still chosen by target (native chunks / legacy rows / pane status, the
latter further gated by the pane's own `toolStatus`).
Flip it off in the slack example (`showToolStatus: false`).
Extend the unscoped-tool attribution test to verify toolCallId persists and
agentId stays undefined after the tool moves InProgress -> Executing, not just
at InProgress.
Code-review follow-up. Replace the unreachable `as any` fallback branch with
a compile-time exhaustiveness check (const _: never = props): a newly-added
ToolCallStatus now becomes a type error that must get its own branch, rather
than silently rendering with respond=undefined. Also correct the prop-build
comment (name/description are overwritten with the registration values, not
'normalized'). No behavior change for the three live statuses.
