+# Deprecating components and hooks in Primer React
+
+Use this skill when a task involves marking a public Primer React API as deprecated.
+
+## What to update
+
+### Source code
+
+- Add a JSDoc `@deprecated` annotation to the exported component, hook, prop, or type following existing patterns nearby.
+- Keep runtime behavior unchanged unless the task explicitly requires more than deprecation signaling.
+
+### Docs metadata
+
+- For components, mark the relevant `*.docs.json` file with `"status": "deprecated"`.
+- For hooks, mark the relevant `*.hookDocs.json` file with `"status": "deprecated"`.
+- If schema or build tooling does not yet support the docs metadata you need, update the corresponding schema/build files in `packages/react/script/*-json/`.
+
+### Documentation content
+
+- If the deprecated component has a docs page or JSON-backed docs content that supports deprecation guidance, add or update the deprecation guidance and recommended alternative.
+- Follow `contributor-docs/deprecating-components.md`.
+
+### Versioning
+
+- Add a changeset for public API deprecations.
+- Use the versioning guidance in `contributor-docs/versioning.md` to choose the correct bump.
+
+## Validation
+
+Prefer targeted validation first, then broader validation if needed:
+
+- Format changed files with `npx prettier --write <paths>`
+- Lint changed TypeScript files with `npx eslint --fix <paths>`
+- Rebuild generated docs metadata when related schema or docs JSON changes:
+
+```bash
+npm run build:hooks.json -w @primer/react
+```
+
+```bash
+npm run build:components.json -w @primer/react
+```
+
+- Run targeted tests for the affected API when available
+- Run broader repository validation before finalizing if the change touches shared build tooling
+
