Open Metadata@OpenMetadata

Set up, verify, or repair a local OpenMetadata development environment on macOS or Linux. Installs the toolchain (Java 21, Maven, Node 22, Yarn 1.x, Python 3.10+, ANTLR 4.9.2, Docker), creates the Python venv, generates models, installs UI dependencies and pre-commit hooks. Use for a fresh clone, a new worktree, onboarding, or when a build fails with a missing/wrong tool.

Generate robust, zero-flakiness Playwright E2E tests following OpenMetadata patterns. Creates comprehensive test files with proper waits, API validation, multi-role permissions, and complete entity lifecycle management.

Use when opening or finalizing a GitHub PR for OpenMetadata. Walks through the repo PR template — linked issue, high-level design (for big PRs), unit/integration/Playwright tests + coverage, UI screen recording, and manual test steps — then drafts a fully-filled PR body and (optionally) creates the PR.

Build and deploy a full local OpenMetadata stack with Docker to test your connector in the UI. Handles code generation, build optimization, health checks, and guided testing.

Run the exact ESLint + Prettier + organize-imports sequence that CI's `UI Checkstyle` workflow runs — on just the files the PR changed — and fail the task if any file ends up with a diff. Invoke after authoring or modifying any `.ts`, `.tsx`, `.js`, `.jsx`, or `.json` file under `openmetadata-ui/src/main/resources/ui/src/`, `.../playwright/`, or `openmetadata-ui-core-components/src/main/resources/ui/src/`, or when CI reports a "UI Checkstyle" failure on the PR.

Deep reliability audit for OpenMetadata connectors — runs 7 investigation prompts (metadata, errors, auth, lineage, scale, synthesis, implementation) against connector standards

Run `mvn spotless:apply` to fix Java checkstyle / formatting failures and verify the result. Invoke after authoring or modifying any `.java` files, or when CI reports a "Java checkstyle failed" or "Fix Java checkstyle" issue on a PR.

Review an OpenMetadata connector against golden standards. Runs multi-agent analysis covering architecture, code quality, type safety, testing, and performance. When a PR number is given, automatically posts the quality summary to the PR description and a detailed review as a PR comment.

Use after implementing any feature or fix to ensure comprehensive test coverage. Enforces 90% line coverage in openmetadata-service, integration tests for all API endpoints in openmetadata-integration-tests, and Playwright E2E tests for UI changes.

Build a new OpenMetadata connector from scratch — scaffold JSON Schema, Python boilerplate, and AI context using schema-first architecture with code generation across Python, Java, TypeScript, and auto-rendered UI forms.

Use when writing or editing React/TSX in `openmetadata-ui/src/main/resources/ui/src/` or `openmetadata-ui-core-components/`, before reaching for a raw `<div>` + Tailwind utility classes to build layout (flex rows/columns, grids, bordered panels with header/body/footer, separators), and before writing any Tailwind color class (`tw:bg-*`, `tw:text-*`, `tw:border-*`) or hex color value. Applies whenever the change adds or restructures a layout container or touches color/dark-mode styling, not to every div.

Load all OpenMetadata connector development standards into context. Use before building or reviewing connectors to ensure consistent patterns.

Meta-skill loaded at session start. Directs Claude to check for applicable OpenMetadata skills before starting any task. Ensures structured workflows are followed.

Use when validating UI changes in a branch require Playwright E2E testing. Reviews branch changes, validates UI with Playwright MCP, and adds missing test cases.

Reviews OpenMetadata and Collate pull requests as a maintainer deciding whether to merge. Use WHENEVER the user asks to review a pull request — any phrasing ("review this PR", "PR review", "can you review
