New users were still discovering cloud.copilotkit.ai through docs pages,
the README, example READMEs, and in-app banners/console messages. Replace
all user-facing web links with dashboard.operations.copilotkit.ai (the
destination the marketing-site CTAs already use). Functional API endpoints
(api.cloud.copilotkit.ai) are deliberately untouched since existing cloud
customers depend on them.

The shared self-hosting snippet renders under every framework section
(built-in-agent, langgraph, ...), and the NavigationLink rewriter makes
absolute links section-relative.
- "Intelligence Platform Works" linked /learn/intelligence-platform,
which became /<framework>/learn/intelligence-platform (404). The page
is served at /premium/intelligence-platform in every section.
- The GHCR chart-releases link used the repo-scoped URL for the private
Intelligence repo (404 for public readers); switched to the public
org-scoped package URL.
Adds two pieces to the self-hosting docs:
1. A short public Callout in `## What is this?` announcing that the
Intelligence Platform image includes an opt-in user memory
capability and pointing readers at the gated configuration section
below. No implementation details exposed.
2. A password-gated `### User memory (closed beta)` sub-section in
`## Configuration reference` that describes:
- The user-visible effect (recall of prior conversations with
example questions)
- Scope guarantees (per-user, per-org, per-project; read-only)
- The two flips required to enable it:
app-api: appApi.env: [{ name: SL_ENABLED, value: "true" }]
runtime: mcpServer: true on the CopilotKitIntelligence
constructor in @copilotkit/runtime/v2
- A runtime.ts code snippet
The gating uses the existing InsecurePasswordProtected component
already registered as an MDX component on both (home) and
integrations routes. The password is currently hardcoded as
cpki-mem-beta directly on the prop, which keeps the gate working
locally without env-var setup. Swap to an env-var-backed prop before
broader rollout if a different password than the existing LangGraph
Cloud beta is desired.
Scope of this change is the self-hosting snippet only; no
integration-specific docs, no new pages, no nav changes.

- Move `package` from properties string to top-level `{ name }` object per
Ben's confirmed IngestPayload schema (telemetry-sink-ingest/index.ts:127-134)
- Add typed per-event helpers trackBannerViewed/trackBannerClicked/trackThreadsTabClicked
to enforce property shapes at call sites and prevent PII leakage under wrong keys
- Add trackBannerClickedOnce guard in index.ts (per-mount Set keyed by
banner_id + cta) to prevent banner_clicked inflation on repeated clicks

Three V1 funnel events from the inspector — oss.inspector.banner_viewed,
oss.inspector.banner_clicked, oss.inspector.threads_tab_clicked — plus a
privacy panel for opt-out, a first-run console disclosure on inspector
mount and runtime startup, and inspector content added to the canonical
/telemetry docs page on main.
Inspector POSTs directly from the browser to telemetry.copilotkit.ai/ingest
(per ticket: URL is intentionally clearly named for transparency in DevTools).
Inline fetch POST in lib/telemetry.ts — no @copilotkit/shared dep on the
inspector, no dependency on any non-main branch.
Wire body shape (conservative; needs Ben confirmation):
POST https://telemetry.copilotkit.ai/ingest
{ event, properties: { ...caller, distinct_id, package }, ts }
If the lambda expects a richer envelope, update the single JSON.stringify
in lib/telemetry.ts.
Privacy invariants:
- Opt-out toggle short-circuits before any network call (verified by test).
- Properties are scoped to event metadata only — no message content, agent
state, prompts, completions, banner markdown. Negative test pins the wire.
- Anonymous distinct ID (UUID v4 in localStorage) set on inspector load and
propagated onto banner CTA links as ?posthog_distinct_id=<uuid> so the
destination site can posthog.alias() and close the
banner_viewed → banner_clicked → signup_attributed funnel. URL param
suppressed when opted out.
- Console disclosure on first inspector mount and runtime startup. Both
link to https://docs.copilotkit.ai/telemetry.
Plan gaps addressed:
- CTA name on banner_clicked: cta:'body'|'dismiss' (click location) plus
optional cta_label read defensively. Sam: confirm dismiss treatment.
- De-anon opt-out folded into the single toggle. Docs say so explicitly.
- banner_viewed dedup: per-instance Set<string> keyed by timestamp.
- EPIC consent / pixel review: out of scope for this PR; flagged at merge.
Deferred for V1.1:
- Wire body shape (Ben).
- Event-type allowlist for oss.inspector.* (Ben — oss-path-to-production).
- posthog_distinct_id URL-param key name (Ben/Tyler/website team).

Mirror of #4430 by @MalaikaAbb.
Adds an agentId note for non-default agents, replaces `agent.id` with
`agent.agentId`, corrects the `@copilotkit/shared/v2` import to
`@copilotkit/shared`, and adds the missing `[agent]` dependency to a
useEffect.
Add an llms.txt section to the shared mcp-server-setup snippet
so /coding-agent-setup and /coding-agents pages tell users
where to find it for tools that don't speak MCP.
Several shared snippets linked to paths that no longer exist:
- /generative-ui/specs/* → /learn/generative-ui/specs/* (specs moved)
- /premium/threads → /threads (page is at root, not under /premium)
- /premium/inspector → /inspector (page is at root, not under /premium)
Because these snippets are inlined into many integration pages,
each broken link multiplied across the site and accounted for the
majority of internal-referrer 404s on docs.copilotkit.ai.
Threads pages: drop @copilotkit/cli-vnext alias for the canonical
@copilotkit/cli, bump react-core minimum from v1.50 to v1.56, and trim
the redundant "(via Copilot Cloud or self-hosted)" parenthetical from
the Prerequisites bullets.
Self-hosting snippet: restructure the "What is this?" intro into a
labeled "What you bring" / "What the chart deploys" pair (with a
component table for ports), tighten the kubeconfig-check sentence, and
collapse the local-validation Callout into two parallel options (bundled
overlay vs one-shot script). Drop the "If none of these apply, use
Copilot Cloud" line — readers who land on /premium/self-hosting have
already opted in.

The Threads, Intelligence Platform explainer, multi-conversation
tutorial, useThreads reference, and the shared threads snippet were
restored at their pre-rollout state, so they carried no OpsPlatformCTA
while peer pages picked one up earlier on this branch. Wires each
restored page to the new try_for_free_clicked event with snake_case
surface identifiers, and fixes the "a Enterprise" → "an Enterprise"
article mismatch the rebrand left in both self-hosting pages.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Renames the platform name across docs prose, CTA copy, frontmatter
descriptions, and the Learn landing card. Three patterns were collapsed
into one canonical form:
- "CopilotKit platform" → "Enterprise Intelligence Platform"
- "CopilotKit Intelligence Platform" → "Enterprise Intelligence Platform"
- "Intelligence Platform" → "Enterprise Intelligence Platform"
URL slugs (/learn/intelligence-platform, /premium/intelligence-platform)
are intentionally unchanged. The CTA component button label
("Get Intelligence free") is also unchanged.
The ThreadsEarlyAccess wrapper hid Threads, the multi-conversation
tutorial, useThreads, and the shared snippet behind a client-side
password splash. Threads is now generally available, so remove the
wrapper from the five MDX entry points, drop the component, and unwire
the MDX registry entries in the home and integrations route handlers.
This restores the Threads management surface (useThreads hook, the
multi-conversation tutorial, per-integration Threads how-tos, the
shared snippet), the Intelligence Platform / self-hosting pages, and
the sidebar entries that were dropped in b08da7970.
This reverts commit b08da79700.
Renames the docs CTA tracking event from `cta_clicked` to
`try_for_free_clicked` to match the per-event custom event names used
on the marketing website, and uses a single `location` string property
in place of the previous `surface` / `variant` / `target` / `page_path`
shape. Surface identifiers are normalized to underscored snake_case to
match the location values already used on the website.
Same change applies to the docs navbar handler that fires when a
visitor clicks the Free Developer Access link.
Adds a sign-up CTA to the shared `prebuilt-components` snippet so it
appears on all twelve per-integration `/{framework}/prebuilt-components`
pages that consume it, and adds a matching CTA to the LangGraph
prebuilt-components page (which uses custom content rather than the
shared snippet).
Moves the Built-in Agent overview CTA from below the features grid to
above the first H2 so it lands above the fold on standard viewports.
Places dashboard sign-up CTAs on topical pages, threads guides,
reference pages, and integration overview pages. Each CTA is tagged
with a stable surface identifier for PostHog attribution and routes to
the dashboard with matching UTM parameters.
Placements include:
- Home and quickstart landing pages
- Prebuilt-components, shared-state, and chat-related reference pages
- Threads how-to, tutorial, reference, and per-integration threads pages
(via the shared snippet)
- Inspector, event-inspector, and learning explainer pages
- Premium overview, observability, headless-ui, and self-hosting pages
(via the shared snippets)
- Integration overview pages — placed via the new afterFeatures slot on
the four FrameworkOverview-based pages (LangGraph, ADK, AWS Strands,
Microsoft Agent Framework) and below the features grid on Built-in
Agent
- Manual-setup quickstart pages (a2a, ag2, agent-spec, built-in-agent,
crewai-flows, deepagents)
Also normalizes platform copy across the affected pages.
Removes the unreleased Threads management surface (useThreads hook,
multi-conversation tutorial, the per-integration Threads how-to, the
shared snippet) and the Intelligence Platform / self-hosting pages
introduced alongside them, plus the ThreadsEarlyAccess gate that wrapped
them. The Learn landing page stays; just drops the Threads card and the
Intelligence Platform card. Sidebars (root, learn, reference/v2/hooks,
12 integrations + their premium subsections) are pruned to match.

## Summary
Three connected features land together so the CopilotKit VS Code
extension becomes a coherent debugger/preview surface:
1. **Hook Explorer** — every V1 + V2 render hook can be discovered and
previewed live with auto-generated controls, an inline `▶️ Preview
Component` CodeLens, and a sidebar that lists every captured site.
2. **AG-UI Event Inspector** — live SSE debug stream of all AG-UI
events, filterable and color-coded, in a sidebar view + editor panel.
3. **A2UI Catalog sidebar → webview** — the last native TreeView gets
replaced with a Tailwind-styled webview that matches the other two, now
with a proper **Go to source** action on components and fixtures.
## Hook Explorer
### Discovery + preview
- oxc-based scanner walks the workspace and finds every call-site of any
hook in the registry (17 across V1 + V2, render + data).
- Preview panel bundles the user's source via Rolldown (IIFE format,
React externalized, CSS collected per `@copilotkit/a2ui-renderer`
pattern), executes it in the webview with a capture-only **stub** for
`@copilotkit/react-core` (+ `/v2`), and mounts the user's component just
long enough to record each hook's config.
- Auto-generated form on the left/top drives the `render` prop's
args/parameters/state/event live. V1 parameter arrays and V2 Zod /
Standard Schema all map through a unified `FormSchema` derived at
runtime from the captured config.
- `useCopilotAction`, `useCopilotAuthenticatedAction_c`,
`useCoAgentStateRender`, `useLangGraphInterrupt`, `useRenderTool`,
`useRenderToolCall`, `useDefaultRenderTool`, `useLazyToolRenderer`,
`useRenderCustomMessages`, `useRenderActivityMessage`,
`useHumanInTheLoop`, `useInterrupt`, `useFrontendTool`, `useComponent`,
`useDefaultTool` all previewable.
- Inline `▶️ Preview Component` CodeLens above every render-hook call
site, backed by the same `copilotkit.hooks.preview` command as the
sidebar.
- Imported render components work: rolldown walks transitive imports
from the hook's `render` prop through any number of sibling files.
- Cross-file hook switches are robust: controls are reset on load,
Harness only mounts once the real HostRoot is ready, a top-level error
boundary auto-recovers when you pick a different hook.
### Why the stub approach
Bundling the real `@copilotkit/react-core` through rolldown's IIFE
output hit a `__commonJSMin` TDZ chain (`require_clipboard`,
`require_graphql`, `require_context_helpers`, …) because the
chat/runtime-client/markdown graph has circular imports. Externalizing
react-core + routing to a Proxy-backed stub that captures hook configs
avoids the whole CJS wrapping problem, shrinks the preview bundle from
~24 MB to ~1.3 KB, and keeps the preview runtime path completely
runnable without a live CopilotKit backend. Tradeoff documented in
`copilotkit-stubs.ts`.
### Weather-themed fixtures
14+ fixtures under `packages/vscode-extension/test-workspace/hooks`,
each a distinct visual scenario (forecast card, severity-palette alerts
with imported CSS, forecast strip, live radar grid, conic-gradient
precipitation gauge, air-quality badge with imported render, pollen
report with a 2-hop import graph, HITL evacuation confirm,
sunrise/sunset gradient, etc.). Used both as regression fixtures and as
the demo surface for video.
### Styling
- Tailwind-via-CDN + VS Code CSS variables for theme-aware chrome.
- User-provided CSS imports collected by rolldown and injected as a
`<style>` tag per load.
- Controls + form fields converted to Tailwind; textarea matches input
styling.
- Framed "Rendered output" card so the render prop is visually
unmistakable.
## AG-UI Event Inspector
### Runtime (`@copilotkit/runtime` + `@copilotkit/shared`)
- `DebugEventBus` — in-memory pub/sub on `BaseCopilotRuntime`, only
instantiated when `NODE_ENV != production`.
- Event tap in `createSseEventResponse` broadcasts every AG-UI event
with metadata (agentId, threadId, runId, timestamp).
- `GET /debug-events` SSE endpoint — returns 404 in production, streams
`DebugEventEnvelope` JSON to connected clients, initial `: connected`
comment flushes headers immediately.
### VSCode Extension
- `DebugStream` — Node SSE client with auto-reconnect, exponential
backoff, URL validation, error surfacing.
- `InspectorPanel` (editor panel, command `CopilotKit: Open AG-UI
Inspector`) and `InspectorViewProvider` (sidebar view) both use a shared
`DebugStream` instance — events persist when switching tabs.
- Inspector React app: `ConnectionBar`, `FilterBar`, `EventList`,
`EventDetail`.
- Color scheme: purple (lifecycle), red (errors), blue (text), orange
(tools), green (reasoning), teal (state), yellow (activity), gray
(unknown).
## A2UI Catalog → webview
- Replaces `ComponentPreviewProvider` (native TreeDataProvider) with
`CatalogListViewProvider` (WebviewViewProvider), matching the Hooks and
Inspector sidebars.
- New React webview with refresh header, component rows (name + relative
path + `auto` badge when no fixture), expandable fixtures list.
- Click a component row → preview (or toggle if it has fixtures); click
a fixture row → preview that fixture.
- Hover action buttons: `▷` preview + `</>` go-to-source on every row.
- "Go to source" opens the component file for component rows; for
fixture rows it opens the fixture file and jumps the cursor to the named
fixture key.
## Test coverage
- Runtime: DebugEventBus unit tests (8), handleDebugEvents endpoint (5),
fetch-router routes (4), integration across Express/Hono/Node/Fetch (9).
- Hooks: scanner + 16 fixture bundle-smoke test, regression guard
against `node_<builtin>` self-references, CSS collector test, stub-based
capture E2E, cross-kind controls remount, FormRenderer defensive
rendering.
- Inspector + webview: DebugStream reconnect (10), inspector components
(17), colors (9).
- Total: **178 tests** passing for the vscode-extension package; runtime
suite unchanged.
## Test plan
- [ ] `pnpm nx run copilotkit-vscode-extension:build` and `pnpm nx run
copilotkit-vscode-extension:test` both green
- [ ] F5 launches the Extension Dev Host with `test-workspace` open
- [ ] Hooks sidebar lists every fixture hook; click a row → preview
opens; `</>` button opens the source
- [ ] `▶️ Preview Component` CodeLens shows above every render hook in a
`.tsx` file; clicking it opens the preview
- [ ] Form controls drive the render live; cross-kind hook switches
(action ↔ custom-message) don't crash; a forced render-prop throw
recovers when a different hook is picked
- [ ] Imported-render fixtures (`ImportedAirQuality`,
`ImportedPollenReport`) bundle and preview correctly
- [ ] A2UI Catalog sidebar is the new webview, refresh works, `</>` on a
fixture opens the fixture file and reveals the named key
- [ ] AG-UI Inspector connects to `GET /debug-events`, filters + detail
work, events survive sidebar/panel switch, invalid URL shows red error
Add the documentation kit for self-hosted CopilotKit Intelligence:
- (root)/premium/self-hosting.mdx — canonical how-to covering platform
prerequisites, values file configuration (AWS ALB/IRSA and on-prem
nginx paths), secret delivery via External Secrets or direct
Kubernetes Secrets, install/verify/upgrade/uninstall steps, and an
inline values.yaml reference
- learn/intelligence-platform.mdx — Diataxis explanation covering the
app-api / app-frontend / realtime-gateway workloads, the
control-plane/data-plane split, the multi-tenancy model
(organization/project/user with auth.deploymentMode postures), the
platform-layer vs application-layer split for self-hosted installs,
secret rotation, scaling, upgrade, error handling, and the
hosted-vs-self-hosted decision
- snippets/shared/premium/self-hosting.mdx — shared snippet that
mirrors the canonical how-to for integration pointer pages
- integrations/*/premium/self-hosting.mdx (12 frameworks) — thin
pointer pages that import the shared snippet, so Self-Hosting is
discoverable from every integration sidebar (a2a has no /premium/
subdir and is intentionally skipped)
- meta.json nav entries in (root)/premium, learn, and every integration
premium sidebar
Also wraps the remaining Threads docs with the ThreadsEarlyAccess gate
(root threads.mdx, shared threads snippet, multi-conversation-chat
tutorial) and replaces the previous "self-hosted Enterprise, configure
your database connection per the Enterprise setup guide" placeholders
with real /premium/self-hosting links — the Threads docs referenced a
setup guide that did not exist until now.

Most framework integrations don't ship their own A2UI rendering tool, so the
shared snippet now guides users to inject `render_a2ui` via
`a2ui: { injectA2UITool: true }`. The LangGraph fixed-schema guide returns A2UI
operations directly from a Python tool, so the middleware auto-detects them and
tool injection is unnecessary — switched to `a2ui: {}` there with a note.
The docs table and prose claimed `debug: true` sets `verbose: true`,
but the implementation intentionally defaults verbose to false (PII
safety). Fixed the table and explanatory text to match.
Also removed packages/vscode-extension/README.md which was committed
on this branch by mistake — it describes an unrelated VS Code extension
and has nothing to do with debug mode.
Updated JSDoc and troubleshooting docs to accurately describe that
the client-side debug prop forwards config to the AG-UI transport
layer, not CopilotKit's own logging. Removed fabricated console.debug
output examples that don't exist.
- Rewrite opening to address the user's problem (missing events, broken
state) rather than describing the feature
- Add cross-link callout from error-debugging → debug-mode and vice versa
- Fix [VERIFY] log format (remove incorrect colon)
- Move troubleshooting scenarios before reference tables since debugging
is the primary use case
- Fix clone() dropping debug config on ProxiedCopilotRuntimeAgent
- Pass raw DebugConfig to agents instead of collapsing to boolean
- Clamp verbose to false when enabled is false
- Fix pino-pretty log format in docs (parentheses, timestamps, levels)
- Add loggedEventCount to doc example
- Fix "Agent run started/finished" → actual log messages in arch docs
- Fix all doc imports to use @copilotkit/runtime/v2 (symbols only
exported from v2 entry point)
- Replace v1 copilotRuntimeNextJSAppRouterEndpoint with v2 pattern
(CopilotRuntime + createCopilotEndpoint + InMemoryAgentRunner)
- Add warning callout on TanStack reasoning example (reasoning events
not surfaced by TanStack converter)
- Fix randomUUID imports in converters: use @copilotkit/shared instead
of Node.js crypto to match codebase convention
- Fix collectEvents timer leak in test-helpers.ts (add clearTimeout)
- Fix JSDoc/comments: convertInputToTanStackAI accurately describes
role allowlist, TanStackInputResult.messages comment updated
- Close TOCTOU window: set abortController synchronously before Observable
creation in classic run(), matching factory run() pattern (M3)
- Add concurrent run guard to classic run() (C1)
- Add threadId/runId to RUN_ERROR events in classic mode (I2)
- Check both 'output' and 'result' property names in classic tool-result (C2/M2)
- Add try/catch around JSON.stringify in classic tool-result (I4/M2)
- Add undefined guards before emitting state snapshot/delta events (I3)
- Guard assignToolsToAgents against factory-mode agent configs (M1)
- Improve error handling in classic error case with proper fallback (C3)
- Improve TanStack converter TODO comment with known gap details (M5)
- Document @ts-expect-error on clone() middlewares access (S1)
- Add JSDoc to AgentFactoryContext.abortController (M4)
- Fix duplicate import and clean up react-router example
- Update docs AgentFactoryContext reference
Source fixes:
- Fix TOCTOU race in concurrent run guard — set abortController
synchronously before Observable creation, closing the window where
two run() calls could both pass the guard
- Add JSON.stringify try/catch in TanStack TOOL_CALL_RESULT handler
(matching existing aisdk.ts protection against circular refs)
- Use role allowlist (user/assistant/tool) instead of denylist in
convertInputToTanStackAI to exclude activity/reasoning roles
- Change error+abort handler from break to return in aisdk converter
to stop processing after error during abort
- Fix version-pinned comments (remove "AI SDK 5.0" reference)
Test fixes:
- Add timedOut flag to collectEventsIncludingErrors to distinguish
hung observables from normal completion
- Add clearTimeout on success/error to prevent timer leaks
- Remove timing-dependent setTimeout in concurrent run guard test
Docs fixes:
- Split imports: copilotRuntimeNextJSAppRouterEndpoint from
@copilotkit/runtime, Agent/converters from @copilotkit/runtime/v2
- Fix forwardedProps example: use CopilotKit properties prop
- Fix useCopilotChat → useCoAgent for state management reference
- Fix model syntax colon → slash (openai/gpt-4o)
Critical fixes:
- Guard concurrent run() calls — throw if agent is already running
- Check both "output" and "result" properties on AI SDK tool-result events
for compatibility with older AI SDK versions
- Handle undefined/missing error in AI SDK error events with proper
Error wrapping instead of throwing undefined
Important fixes:
- Add TOOL_CALL_RESULT handling to TanStack converter (was silently dropped)
- Include threadId and runId in RUN_ERROR events for run correlation
- Guard state tool events (STATE_SNAPSHOT/STATE_DELTA) against undefined
snapshot/delta fields before emitting
- Wrap JSON.stringify in tool-result with try/catch to handle circular refs
- Fix collectEventsIncludingErrors to distinguish error vs normal completion
Test coverage:
- Add tests for convertInputToTanStackAI (message filtering, tool call
mapping, context injection, state serialization)
- Add tests for state management tool results in AI SDK converter
- Add tests for async factory (Promise-returning) paths
- Add tests for tool-result property compatibility (output vs result)
- Add tests for error event handling edge cases
- Add tests for concurrent run guard and RUN_ERROR correlation fields
- Replace flaky setTimeout-based abort test with signal-based sync
Other:
- Add exhaustiveness check (default: never) in config type switch
- Document clone() @ts-expect-error coupling with AbstractAgent.middlewares
- Fix docs: remove incorrect "v6" version reference, fix wrong hook name
- New docs/(root)/migration-guides/ section with migrate-to-v2, migrate-attachments,
migrate-to-1.10.X, migrate-to-1.8.2
- Troubleshooting now only contains error-debugging, observability-connectors, common-issues
- Update all @deprecated JSDoc URLs from /troubleshooting/ to /migration-guides/
- Update doc cross-links (multimodal-attachments page, snippet import)
- Move snippet to snippets/shared/migration-guides/
- Set minimum version to v1.56.0 (was vX.Y.Z placeholder)
Attachment queue & previews:
- Image lightbox with View Transition API morph animation
- Video lightbox with native controls and play button overlay
- Document lightbox (PDF via blob URL, text inline, info card fallback)
- Drop zone overlay with upload icon
- Filename preservation via InputContent metadata
- Proper video thumbnail sizing and play/pause indicator
- Fix attachment queue positioning (max-w-3xl constraint)
- Padding between X button and content for audio/document cards
- Document filenames wrap instead of truncating
Attachments config:
- onUploadFailed callback for validation/upload errors (file-too-large, invalid-type, upload-failed)
- onUpload accepts sync or async returns
- AttachmentUploadResult discriminated union with explicit interfaces
- Metadata field on Attachment and onUpload return type
AG-UI version bump:
- Bump @ag-ui/client, @ag-ui/core, @ag-ui/encoder, @ag-ui/proto to 0.0.51
- Remove process.env Vite workaround (fixed upstream in 0.0.51)
Deprecation lifecycle:
- @deprecated JSDoc on all legacy image upload APIs
- ImageRenderer, ImageRendererProps, ImageUpload type, imageUploadsEnabled prop,
inputFileAccept prop, ImageRenderer prop, AIMessage.image, ImageData
- Codemod at codemods/migrate-attachments.ts (15 tests)
- Migration guide updated with codemod instructions and new type shapes
Docs:
- New guide: docs/(root)/multimodal-attachments.mdx
- Updated migration guide with onUpload return type, metadata, codemod section

- Label change: "Add photos or files" → "Add attachments"
Tests:
- CopilotChat.attachments.test.tsx — 5 tests for onUploadFailed
- migrate-attachments codemod — 15 tests
Moves the streaming performance tip into a reusable snippet and imports
it on both the root headless page and the v2 basics headless-ui snippet
(used by built-in-agent and a2a framework pages).

Update user-facing references from "LangGraph" to "LangChain" per CPK-7186.
The integration label, descriptions, and agent terminology now use "LangChain"
while preserving "LangGraph" for technical references (Platform, Studio, CLI,
StateGraph, code/package names, and API references).
- Rename integration label in integrations.ts, meta.json, integration-grid,
feature-matrix, quickstart-dropdown, and link-validation
- Update ~47 MDX docs: "LangGraph agent(s)" → "LangChain agent(s)"
- Update FAQ, snippets, and learn section references
- Keep URL paths (/langgraph) unchanged for backward compatibility
- Keep all code imports, package names, and LangGraph Platform/Studio/CLI as-is
