When the user wants to review, edit, or improve existing website and marketing copy, especially requests like "review copy", "audit copy website", "polish landing page copy", "improve messaging", "tighten this text", or "copy feedback". Use this for existing copy in frontend/src and frontend/docs. For rewriting from scratch, hand off to copywriting. For structural conversion issues (section flow, CTA placement, friction), hand off to page-cro.

Generate a conventional commit message from staged/unstaged changes and automatically commit.

Create a structured implementation plan for a new feature, refactor, or infrastructure change. Outputs a machine-readable markdown plan with phases, tasks, requirements, and testing criteria.

Create optimized multi-stage Dockerfiles for Next.js frontend and FastAPI backend. Smaller images, non-root user, healthcheck, pinned versions.

Generate a Playwright TypeScript E2E test for a given scenario. Navigates the app step-by-step, uses role-based locators, and saves the test in tests/e2e/.

PostgreSQL query optimization and schema review. Covers EXPLAIN ANALYZE, indexing strategy, JSONB, pagination, and security (parameterized queries).

Run pytest with coverage, identify uncovered lines, and iteratively add tests until 100% coverage is reached.

Surgical code refactoring to improve maintainability without changing behavior. Use for gradual improvements: extract functions, eliminate code smells, improve type safety, apply design patterns.
