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	/tdd then /test-enforcement (must include Jest + Playwright if user-facing)
Code review / PR review	/code-review then /test-enforcement
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.

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).

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 lint
• 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.
