openmetadata-workflow - Claude MCP Skill

# OpenMetadata Development Workflow

This skill is loaded automatically at session start. It ensures you follow the right workflow for every task.

## Before Starting Any Task

**Check which skills apply to your task and use them.** This is not optional — if a skill applies, you must follow it.

### Skill Selection Guide

| Task type | Required skill(s) |
|---|---|
| New feature (multi-file) | `/planning` then `/tdd` then `/test-enforcement` then `/verification` |
| Bug fix | `/systematic-debugging` then `/tdd` (write regression test) then `/verification` |
| New API endpoint | `/planning` then `/tdd` then `/test-enforcement` (must include integration test) |
| New connector | `/connector-standards` then `/connector-building` then `/test-enforcement` |
| UI component | **Read `openmetadata-ui/src/main/resources/ui/DEVELOPER_HANDBOOK.md` first** (folder structure + file naming for any new file), then `/ui-core-components` + `/react-best-practices` + `/composition-patterns` **before writing**, then `/tdd`, then `/web-design-guidelines` **after**, then `/test-enforcement` (must include Jest + Playwright if user-facing) |
| UI a11y / UX / design audit | `/web-design-guidelines` |
| React perf work (re-renders, waterfalls, bundle) | `/react-best-practices` |
| Code review / PR review | `/code-review` then `/test-enforcement` |
| Opening / finalizing a PR | `/test-enforcement` then `/verification` then `/pr-checklist` |
| Connector review | `/connector-review` |
| E2E test creation | `/playwright` |
| Finishing implementation | `/test-enforcement` then `/verification` |

> **Note:** Connector skills (`/connector-standards`, `/connector-building`, `/connector-review`) and `/playwright` are part of the OpenMetadata Skills plugin and ship together with this workflow skill. They are defined in the `skills/` directory alongside this file.

> **Why the UI row names skills explicitly:** a skill only loads when it is invoked, and the model
> decides that from the skill's own `description`. `/composition-patterns` describes itself as being
> for *refactoring* prop proliferation and *building component libraries*, and
> `/web-design-guidelines` describes itself as being for *"review my UI" / "check accessibility"* —
> so neither reliably fires on "build me a component". Naming them here is what makes them part of
> the workflow instead of a coin flip. Invoke `/web-design-guidelines` **after** the component
> exists: it is an audit, and running it first works against its own trigger.
>
> `/react-best-practices`, `/composition-patterns` and `/web-design-guidelines` are vendored from
> [vercel-labs/agent-skills](https://github.com/vercel-labs/agent-skills) (MIT) under
> `skills/vendor/`. They are authoring aids, not gates — enforcement is `ui-checkstyle`, see
> [`docs/ui-code-quality-gate.md`](../../docs/ui-code-quality-gate.md).

### Workflow Rules

1. **Plan before coding.** For any non-trivial task, use `/planning` to design the approach before writing code.

2. **Test-first when possible.** Use `/tdd` to write failing tests before implementation. This applies to Java, Python, and TypeScript equally.

3. **Always enforce test coverage.** Before any PR, use `/test-enforcement` to verify:
   - 90% line coverage on changed Java classes
   - Integration tests for all changed/new API endpoints
   - Playwright E2E tests for new user-facing features
   - Jest unit tests for new React components

4. **Verify with evidence.** Use `/verification` before claiming completion. Show actual test output, not claims.

5. **Review before merging.** Use `/code-review` for two-stage review (spec compliance + code quality).

6. **Fill the PR template completely.** Use `/pr-checklist` before `gh pr create` to gather every required section: linked issue, high-level design (large PRs), tests + coverage, UI screen recording, and manual test steps.

### OpenMetadata Cross-Layer Checklist

When your task touches multiple layers, ensure all are synchronized:

- [ ] JSON Schema in `openmetadata-spec/` → run `make generate`
- [ ] Connection schema → run `yarn parse-schema`
- [ ] Java entity changes → Flyway migration in `bootstrap/sql/migrations/`
- [ ] Backend API changes → update frontend API client
- [ ] New UI strings → add to `locale/languages/en-us.json` then run `yarn i18n`
- [ ] Java files → run `mvn spotless:apply`
- [ ] Python files → run `make py_format && make py_format_check`
- [ ] TypeScript/React files → run `yarn organize-imports:cli && yarn lint:fix && yarn pretty:base --write`
- [ ] New source files → ensure Apache 2.0 license header (run `yarn license-header-fix`)
- [ ] Application changes → run `yarn generate:app-docs`

### CLAUDE.md Takes Precedence

If CLAUDE.md instructions conflict with any skill, **CLAUDE.md wins**. Skills are supplementary workflows, not overrides.
