## Critical Rules

### Do Not Manually Edit Generated Files

- `web/src/api/generated/schema.d.ts` — regenerated via `make generate-api`
- `document/docs/` — auto-generated user documentation (VitePress)
- `server/skillhub-app/src/main/java/com/iflytek/skillhub/dto/` — some DTOs may be generated

### After Making Changes

**Backend changes:**
- Edit Java code → `make dev-server-restart` (local dev)
- Add/modify controller → `make generate-api` to regenerate frontend types
- Add/modify domain service → `make test-backend-app` to verify tests

**Frontend changes:**
- Edit TypeScript/React → Vite HMR handles reload automatically
- After `make generate-api` → commit updated `web/src/api/generated/schema.d.ts`

**Always run before PR:**
```bash
make test-backend-app   # Backend tests (with dependent modules)
make typecheck-web      # Frontend type check
make lint-web           # Frontend lint
make staging            # Full staging regression + smoke test
```

### File-Specific Requirements

- **Controllers** (`skillhub-app/controller/`) are transport only: extract auth context,
  bind request params, wrap responses. No business logic.
- **App Services** (`skillhub-app/service/`) orchestrate workflows. Do not embed complex
  read-model assembly here — extract to query repositories.
- **Query Repositories** (`skillhub-app/repository/`) handle read-model joins and presentation
  projection. Named like `*QueryRepository`.
- **Domain Services** (`skillhub-domain/*/service/`) contain business rules and state transitions.
  Return domain objects, not DTOs.
- **Repository Interfaces** are defined in `skillhub-domain`, implemented in `skillhub-infra`.
- **Domain Exceptions** use `LocalizedDomainException` for user-facing messages with i18n keys.
- **Package-info files** (`package-info.java`) should exist for all packages.

## Development Workflow

### Build & Start

```bash
make dev-all          # Start full stack: Postgres, Redis, MinIO, backend, frontend
make dev-all-down     # Stop everything
make dev-all-reset    # Full reset (clears data volumes)
make dev-status       # Check service status
make dev-server-restart  # Restart backend after Java changes
```

**Access points:**
- Web UI: `http://localhost:3000`
- Backend API: `http://localhost:8080`
- Scanner: `http://localhost:8000`

**Local mock users** (no password needed):

| User ID | Role | Header |
|---------|------|--------|
| `local-user` | Regular user | `X-Mock-User-Id: local-user` |
| `local-admin` | Super admin | `X-Mock-User-Id: local-admin` |

**Bootstrap admin** (password-based, local profile):
- Username: `admin` / Password: `ChangeMe!2026`
- Disable with `BOOTSTRAP_ADMIN_ENABLED=false`

### Lint & Format

```bash
# Backend: enforced by Maven build (no separate lint target)
# Frontend:
make lint-web           # ESLint check
make typecheck-web      # TypeScript check
```

### Testing

```bash
make test-backend-app         # Backend unit tests (skillhub-app + dependencies)
make test-backend             # All backend module tests
make test-frontend            # Frontend unit tests (Vitest)
make test-e2e-frontend        # Frontend E2E tests (Playwright)
make test-e2e-smoke-frontend  # Frontend E2E smoke tests
./scripts/smoke-test.sh       # API smoke test
make namespace-smoke          # Namespace workflow smoke test
```

### Staging (Pre-PR Regression)

```bash
make staging          # Build backend Docker image + frontend static + smoke test
make staging-down     # Tear down
SERVICE=web make staging-logs  # View Nginx logs
```

Staging validates the containerized deployment path:
- Backend: built as Docker image from local source
- Frontend: built as static files, served by Nginx
- Dependencies: same Postgres/Redis/MinIO as local dev

### Parallel Agent Workflow

For parallel development with isolated worktrees:

```bash
make parallel-init TASK=feature-name
```

Creates dedicated Claude, Codex, and integration worktrees as sibling directories.
See `docs/13-parallel-workflow.md` for details.

## PR Submission

### PR Title Format

Use conventional commit style:

```
<type>(<scope>): <description>
```

**Types:**
- `feat`: New feature
- `fix`: Bug fix
- `docs`: Documentation changes
- `test`: Adding or updating tests
- `refactor`: Code restructuring (no behavior change)
- `chore`: Build, CI, or maintenance tasks

**Scopes:** Module or domain name (e.g., `auth`, `search`, `publish`, `review`, `namespace`)

**Examples:**
```
feat(auth): add local account login
fix(publish): resolve null pointer in skill validation
docs(deploy): clarify runtime image usage
test(namespace): add membership service tests
refactor(review): extract query repository for governance list
chore(ci): add parallel workflow scripts
```

### Pre-PR Checklist

- [ ] Backend tests pass: `make test-backend-app`
- [ ] Frontend typecheck passes: `make typecheck-web`
- [ ] If API changed: `make generate-api` was run and `web/src/api/generated/schema.d.ts` is committed
- [ ] Smoke test passes: `make staging`
- [ ] Follow existing module boundaries and dependency direction
- [ ] Add/update tests for new behavior
- [ ] Update docs when APIs, auth flows, deployment, or operator workflows change

## Core Concepts

### Backend Clean Architecture

```
app → domain, auth, search, storage, infra, notification
infra → domain          # implements domain repository interfaces
auth → domain
search → domain
notification → domain
storage → (independent) # pure SPI
```

**Design intent**: `skillhub-domain` is the innermost layer. It defines entities, repository
interfaces, and domain services without depending on infra, auth, search, or storage.

**Code reality**: `skillhub-domain` declares a Maven dependency on `skillhub-storage`, and several
domain services (`SkillHardDeleteService`, `SkillDownloadService`, `SkillPublishService`,
`SkillGovernanceService`, `SkillQueryService`, `SkillStorageDeletionCompensationService`) import
`com.iflytek.skillhub.storage.ObjectStorageService`. This is an existing deviation from the ideal.
New code should avoid adding further cross-module dependencies from domain.

### Repository / Query Boundary

When adding new read logic, follow these rules:

1. **Domain repository ports** (`skillhub-domain`): Aggregate reads, state transitions, rule
   evaluation. Used by domain services.
2. **App query repositories** (`com.iflytek.skillhub.repository`): Read-model assembly that joins
   multiple sources, presentation projection. Used by controllers and app services.
3. **App services** (`com.iflytek.skillhub.service`): Workflow orchestration. Should express "what
   this endpoint does", not "how it assembles DTOs".
4. **Direct SQL / EntityManager**: Only when necessary, with class-level comment explaining why.

**Do not** add complex read-model assembly logic inside app services. Extract it into a query
repository when it joins multiple sources, does presentation projection, or is reused across services.

### Skill Lifecycle

`SkillVersionStatus` values: `DRAFT`, `SCANNING`, `SCAN_FAILED`, `UPLOADED`, `PENDING_REVIEW`,
`PUBLISHED`, `REJECTED`, `YANKED`.

`SkillStatus` enum values: `ACTIVE`, `HIDDEN`, `ARCHIVED`.

The design doc (`docs/14-skill-lifecycle.md`) specifies that `hidden` should be treated as a
governance overlay rather than a lifecycle state. The current code still defines
`SkillStatus.HIDDEN` in the enum. Follow the design doc's intent for new code.

**Key transitions:**
- Normal user first upload → `PENDING_REVIEW` (no initial DRAFT)
- SUPER_ADMIN first upload → `PUBLISHED` (direct publish)
- Review approve → `PENDING_REVIEW` → `PUBLISHED` (updates `latestVersionId`)
- Review reject → `PENDING_REVIEW` → `REJECTED`
- Withdraw review → `PENDING_REVIEW` → `UPLOADED` (also deletes pending review_task)
- Yank → `PUBLISHED` → `YANKED` (must recalculate `latestVersionId`)
- Hide/restore → independent `hidden` flag (governance overlay)
- Archive/Unarchive → `ACTIVE` ↔ `ARCHIVED` (container state)

### Namespace Coordinate System

SkillHub uses `@{namespace_slug}/{skill_slug}`:
- `@global/my-skill` — Platform-level public namespace
- `@my-team/my-skill` — Team/department namespace

ClawHub CLI compatibility maps:
| SkillHub | Canonical Slug |
|----------|---------------|
| `@global/my-skill` | `my-skill` |
| `@team-name/my-skill` | `team-name--my-skill` |

### Authentication

- Web: OAuth2 (GitHub) + local password auth
- CLI: OAuth Device Flow (web authorization → CLI credentials)
- Programmatic: API tokens (prefix-based secure hashing)
- Session: Spring Session + Redis

### RBAC

Platform roles: `SUPER_ADMIN`, `SKILL_ADMIN`, `USER_ADMIN`, `AUDITOR`
Namespace roles: `OWNER`, `ADMIN`, `MEMBER`

### Skill Package Protocol

- Root: `SKILL.md` with YAML frontmatter (`name`, `description` required)
- Allowed extensions (50+ types): `.md`, `.txt`, `.json`, `.yaml`, `.yml`, `.js`, `.ts`, `.py`,
  `.sh`, `.png`, `.jpg`, `.svg`, and many more (see `SkillPackagePolicy.ALLOWED_EXTENSIONS`)
- Limits: 10MB per file, 100MB total, 500 files max
- File type signatures validated (PNG magic bytes, SVG content check, etc.)

### Frontend State Management

- **TanStack Query** (`@tanstack/react-query`): All server state (API data)
- **Zustand**: Local/UI state (theme, sidebar, modals)
- **Never** use `useEffect` for data fetching

### Frontend Component Composition

- **Radix UI** primitives: `@radix-ui/react-dropdown-menu`, `@radix-ui/react-select`
- **class-variance-authority** (cva) for component variants
- **clsx** + **tailwind-merge** for class merging
- **`cn()` utility**: `web/src/shared/lib/utils.ts`
- shadcn/ui is NOT used as a library — only Radix primitives + utility composition

## Common Patterns

### Code Style

**Java:**
- User identity type is always `String` throughout the codebase
- Use Java 21 features (records, pattern matching, virtual threads)
- Follow existing naming patterns in the domain layer
- Error strings for `DomainBadRequestException`, etc. should be clear and actionable

**TypeScript:**
- Strict mode. No `any` types.
- Use generated OpenAPI types for all API interactions.
- Feature-Sliced Design: place code at the lowest appropriate layer.

### Testing Philosophy

- Backend: JUnit 5 + Mockito + AssertJ
- Frontend: Vitest for unit tests, Playwright for E2E
- **Use `make test-backend-app`** (includes `-am` for dependent modules) — never run
  `./mvnw -pl skillhub-app clean test` directly, as it can use stale Maven cache artifacts
- Test behaviors, not implementations
- Use Spring Boot test slices where possible (`@WebMvcTest`, `@DataJpaTest`)

### Frontend Testing

```bash
make test-frontend            # Vitest unit tests
make test-e2e-frontend        # Playwright E2E
make test-e2e-smoke-frontend  # Playwright smoke (subset of E2E)
```

### Logging Conventions

- **Backend**: SLF4J + Spring Boot logging. Use structured logging with MDC for request tracing.
- **Frontend**: `console.error` for errors, `console.warn` for deprecations, avoid `console.log` in production code.
- **Scanner**: Python logging module with structured JSON output.

### Security

- API tokens are stored as prefix-based secure hashes, never in plaintext
- OAuth2 client secrets and other secrets must not be logged or committed
- User identity is `String` (supports external SSO/OIDC/SCIM identity sources)
- The bootstrap admin (`BOOTSTRAP_ADMIN_ENABLED`) is for zero-config quickstart only

## Search Tips

```bash
# Find all REST endpoints
rg "@(Get|Post|Put|Delete|Patch)Mapping" --type java

# Find domain services
rg "class.*Service" server/skillhub-domain/

# Find query repositories
rg "QueryRepository" server/skillhub-app/

# Find controllers
rg "@RestController" server/skillhub-app/

# Find RBAC role checks
rg "@PreAuthorize" server/skillhub-app/

# Find skill validation logic
rg "SkillPackage" server/skillhub-domain/

# Find frontend features
rg "export" web/src/features/

# Find OpenAPI type generation script
rg "generate-api" web/package.json

# Find event listeners
rg "@EventListener" server/
```

## Design Philosophy

- **Hub first**: The server-side registry is the core product; CLI and agent integrations are entry capabilities
- **Compatibility first**: Support `SKILL.md` format and common directory conventions
- **Layered architecture**: Search and object storage must have replaceable boundaries (SPI pattern)
- **Open authentication**: OAuth2-based, extensible to multiple providers beyond GitHub
- **Audit first**: Enterprise distribution requires audit trails for publish, download, delete, and authorization
