## Documentation Sync
The documentation site lives at `apps/docs/` (Docusaurus 3, `@homarr/docs`).
When modifying user-facing code, you MUST also update the corresponding documentation:
- New integration → `apps/docs/docs/integrations/<slug>/index.mdx` + `index.ts`
- New widget → `apps/docs/docs/widgets/<slug>/index.mdx` + `index.ts`
- Changed API → `apps/docs/docs/management/api/index.mdx`
- New/changed env vars → `apps/docs/docs/advanced/`
- New CLI commands → `apps/docs/docs/advanced/command-line/`
- Auth changes → `apps/docs/docs/advanced/` SSO pages
- New cron job → `apps/docs/docs/management/tasks.mdx`
## Monorepo Commands
- `pnpm dev` — Next.js app only
- `pnpm dev:cli -- dev` — run the developer CLI without installing a global binary
- `pnpm db:seed` — seed default database data explicitly
- `pnpm docker:dev:up` — start the Redis development service in the background
- `pnpm dev:docs` — Docusaurus docs site only
- `pnpm turbo build` — build all packages
- `pnpm turbo build --filter=@homarr/docs` — build docs only
- `pnpm turbo typecheck` — typecheck all packages
- `pnpm lint` / `pnpm format` — oxlint / oxfmt
## Code Style
- Lint: oxlint (not ESLint)
- Format: oxfmt (not Prettier)
- UI: Mantine (not Tailwind) — Tailwind is only used in docs app
- Mantine: use the project-scoped MCP server in `.mcp.json` for current v9 APIs, and check `packages/ui/` before creating a new primitive.
- Icons: @tabler/icons-react
- Docs app can import from `@homarr/definitions` for shared types
- Run `pnpm dev:cli -- dev` to browse local `homarr:*` images and remote PR images.
- Run `pnpm dev:cli -- build <name>` from a Homarr checkout to build `homarr:<name>` with rebuild provenance.
- Run `pnpm dev:cli -- build --pr <number>` to build a PR locally from a temporary checkout.
- Run Go checks from `tools/homarr-dev` with `go test ./...` and `go vet ./...`.
## Agent Skills
Portable skills live in `.agents/skills/`. Read the relevant `SKILL.md` before working in that domain; detailed references are loaded only when needed. Claude-compatible discovery is provided through `.claude/skills`.
- `codebase-context` — architecture, package boundaries, and shared utilities
- `documentation-sync` — required user-facing documentation updates
- `mcp-integration` — safe tRPC-to-MCP exposure
- `homarr-custom-widget` — safe Custom JSX v2 authoring
