| description | Add a vendor-official or community adapter to the Chat SDK catalog and docs — adapters.json registry, chat/adapters catalog entry, the docs MDX page, meta.json, integration-test lists, and a changeset. Use when a developer wants to add, list, register, or submit a third-party (vendor-official or community) adapter to this repo, add an adapter to the catalog, or create or edit an adapter docs page under apps/docs/content/adapters/vendor-official or apps/docs/content/adapters/community. |
Add a catalog adapter (vendor-official or community)
Use this to list a third-party adapter in the Chat SDK catalog and docs. It is not for building a first-party packages/adapter-* package.
Gather the source — never invent details
Ask the user for:
- Their adapter's GitHub repository URL.
- Their docs or README.
Read both. Everything you write into the catalog and docs must come directly from those sources or from the user. Do not assume or guess any information:
packageName — read it from the repo's package.json, verbatim.- Factory export (e.g.
createFooAdapter) — read it from the package's exports/source. Do not guess it from the display name.
type (platform or state), env vars, and the feature matrix — base these on what the code and README actually document.- Install and usage snippets — take them from the README; do not write example code the adapter may not support.
If the repo or README does not make something clear, stop and ask the user rather than filling it in. When in doubt, ask.
Choose the slug (kebab-case) and confirm it is not already taken: ls apps/docs/content/adapters/*/.
Pick the tier
- community — listed in the docs only. No
chat/adapters catalog entry, no changeset.
- vendor-official — a maintained/blessed adapter. Everything community has, plus a
chat/adapters catalog entry, a matching create-chat-sdk scaffold-spec entry, and a changeset. Frontmatter adds vendorOfficial: true and author.
Files to change
<tier> is vendor-official or community.
apps/docs/content/adapters/<tier>/<slug>.mdx — the docs page. Start from assets/adapter.mdx. The filename basename must equal the slug frontmatter field, and the page must render <FeatureSupport />.apps/docs/content/adapters/<tier>/meta.json — add "<slug>" to the pages array.apps/docs/adapters.json — add a registry entry: name, slug, type, community: true, description, packageName, author, readme (the GitHub URL). Add vendorOfficial: true for vendor-official.packages/integration-tests/src/docs-adapters.test.ts — add "<slug>" to the hardcoded expected list for its tier.packages/integration-tests/src/documentation-test-utils.ts — add the packageName to VALID_DOC_PACKAGES, plus every import specifier used in the MDX code blocks (subpaths count separately).
Vendor-official also:
packages/chat/src/adapters/index.ts — add an ADAPTERS entry with group: "vendor-official". Reuse the env/secretEnv/urlEnv helpers; use env: { notes: "…" } when there are no env vars. See packages/chat/src/adapters/AGENTS.md.packages/create-chat-sdk/src/catalog/scaffold-spec.ts — add a matching "<slug>": { invocation: … } entry, modeled on a similar adapter. This is a required registration step, not a behavior change: the object is satisfies Record<AdapterSlug, …>, so every catalog slug must have one or create-chat-sdk fails to type-check..changeset/<slug>-adapter.md — "chat": patch + "create-chat-sdk": patch, one line describing the addition.
Invariants the tests enforce
- Registry ↔ catalog parity.
Object.keys(ADAPTERS) must equal the adapters.json slugs where !community || vendorOfficial. So vendor-official must be in chat/adapters; community-only must not be. This is why community adapters skip steps 6–8.
- peerDeps ↔ PackageInstall. The catalog entry's
peerDeps (sorted) must exactly equal the extra packages in the MDX <PackageInstall package="…" />, after removing the adapter's own packageName, chat, and any @chat-adapter/state-*. Easiest: peerDeps: [], install only <packageName> chat (plus a state adapter) in PackageInstall, and keep any other imports in fenced code blocks.
- Fields match.
packageName, type, community, and vendorOfficial must match between the MDX frontmatter and the adapters.json entry.
- Required frontmatter:
title, description, packageName, slug, tagline, type (platform | state), mdxBody: true, community: true (plus vendorOfficial: true and author for vendor-official).
- Imports. Every import in an MDX code block must be listed in
VALID_DOC_PACKAGES.
