Throw when a catalog definition has no matching renderer so createCatalog
satisfies strict check-types under Angular's tsconfig.

Align surface operation normalization and catalog test fixtures with the
RendererProps contract so the changed A2UI web-components pass tsc.

A2UIViewer.tsx and theme/viewer-theme.ts were left behind by the
0.8 -> 0.9 migration: nothing imports them, they import @a2ui/lit
(no longer a dependency) and files that no longer exist, so
check-types fails on files no PR touches. Remove them along with the
now-inert @a2ui/lit external/global entries in tsdown.config.ts, and
underscore the unused type params kept on deprecated aliases for
call-site compatibility.
Follow-up to #5345 per review feedback:
- Propagate the provider change to all remaining skills: every example,
props table, eval check, and prose mention now recommends CopilotKit
imported from @copilotkit/react-core/v2 (the compatibility bridge and
strict superset) instead of CopilotKitProvider. Migration docs in
copilotkit-upgrade now point at the /v2 import path as the target and
explicitly warn against migrating to CopilotKitProvider.
- Scrub CopilotCloud / Copilot Cloud / CopilotKit Cloud branding from
skills, replacing it with CopilotKit Intelligence where the hosted
platform is meant. Literal endpoint URLs and real identifiers like
MissingPublicApiKeyError are unchanged.
- Fix react-core provider-setup.md which claimed publicApiKey was the
canonical prop; publicLicenseKey is canonical and publicApiKey is a
deprecated alias, matching #5345.
- Edits made in the packages/*/skills source dirs for the three mirrored
skills, with skills/ regenerated via pnpm sync:plugin-skills (this also
re-pins the plugin version fields to 1.59.5).
Adds two CI signals for keeping the published packages small and broadly compatible:
- Bundle size: size-limit file-mode config across packages plus a
CopilotChat import-size regression signal (gzip) so growth in the
headline consumer entrypoint is visible on every PR. A bundle-size
workflow comments results on the PR (Phase 1: no hard-fail).
- ES compatibility: a compat-check (es-check) script across 9 packages
with a root .browserslistrc, validating built .mjs/.cjs against the
es2022 build target.
The measure script is importable (measureBundle) and unit-tested. Dev
docs live under dev-docs/ (bundle-size.md, browser-compat.md). All
action refs are pinned to full commit SHAs for supply-chain safety.
The prepack script ran `pnpm run build` during `pnpm publish`, duplicating
the build that prerelease.ts/publish-release.ts already do across the
workspace. With tsdown's `exports: true` regenerating package.json's
exports field on every build, the second rewrite happened mid-publish
and pnpm's pack step failed with ENOENT on the staging tarball.
No other monorepo package has prepack — bringing a2ui-renderer in line.

- setup-endpoint Express delegate: stream SSE via Readable.fromWeb().pipe(res) instead of buffering via arrayBuffer(); applies to both the recommended pattern and the CRITICAL "Correct" example. Add Node 18.17+ note.
- built-in-agent frontmatter: maxSteps defaults to undefined (AI SDK stops after one generation), not 1.
- built-in-agent examples: replace bare anthropic("claude-sonnet-4") / anthropicText("claude-sonnet-4") with the dated id "claude-sonnet-4-5-20250929" (AnthropicMessagesModelId in @ai-sdk/anthropic@3.0.49 does not accept the bare form).
- 0-to-working-chat Next.js: align catch-all with migration-playbook — use [[...slug]] so the bare /api/copilotkit basePath also routes.
- migration-playbook v1->v2 parameters: v1 entries default to required: true; only map to .optional() when required: false was explicit. Prevents silently flipping the contract.
- switching-agents Recipe 2 (Tabs): hold activeAgent in a ref so the onAgentsChanged subscribe effect only re-binds on copilotkit change, not on every tab click.
- a2ui-rendering custom-catalog example: use the real createCatalog(definitions, renderers) signature with Zod schemas; remove the bogus extractSchema<T>() generic (types erase at runtime).
- spa-without-runtime clipboard handler: correct the comment — returning a structured error does NOT trigger onError with tool_handler_failed; only thrown handlers do.
- Wrap the loading-skeleton provider example in children (was self-closing
while every other example wraps CopilotChat).
- Declare `const theme` in the custom catalog snippet so the `a2ui={{ theme,
catalog }}` spread isn't referencing an undefined identifier.
- Mirror the real built-in bridge's `if (copilotkit.properties)` guard in
the try/finally cleanup example so the pattern doesn't throw
`TypeError: Cannot destructure null` and mask the original runAgent error.
- Drop the "Explicit renderer" subsection: construction-only example
contradicted the adjacent "do NOT pass to renderActivityMessages"
anti-pattern and had no legitimate usage snippet.
- Clarify frontmatter: `createA2UIMessageRenderer` ships from
`@copilotkit/react-core/v2`; low-level primitives ship from
`@copilotkit/a2ui-renderer`. Removed stale `@ag-ui/a2ui-middleware`
reference since no example imports it.
- Wrap Python examples in `async def agent_generator():` and mark as
pseudocode (surface_id kwarg shape varies by A2UI SDK version).
- Soften the "only @copilotkitnext/angular" blanket claim to describe the
specific mistake instead.
- package.json: add per-condition `types` to the `exports` map so
`attw --profile node16` and TS `moduleResolution: node16/nodenext/bundler`
consumers resolve types correctly via both import and require.
- Replace custom { name, props } schema format with spec-aligned inline
catalog format (allOf + properties) so the LLM sees the same flat
structure it must produce — eliminates "props" nesting confusion.
- Restructure generation prompts: inline literal values are the default,
path binding is a narrow schema-driven exception for form inputs.
- Export InlineCatalogSchema type from a2ui-renderer.
