Onboard Claude to an existing brownfield project. Discovers the stack, conventions, and architectural decisions from the codebase, surfaces and resolves genuine conflicts interactively, then produces CLAUDE.md plus context/ artifacts (conventions, decisions, onboard-report). Re-run aware — detects prior onboards and offers Refresh (carry forward resolved decisions) or Fresh (start from scratch). Use when a team lead wants to set Claude up on an existing repo.

Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallise. Use when user wants to stress-test a plan against their project's language and documented decisions.

Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.

Break a plan, spec, or PRD into independently-grabbable issues on the project issue tracker using tracer-bullet vertical slices. Use when user wants to convert a plan into issues, create implementation tickets, or break down work into issues.

Review a completed implementation before raising a PR. Verifies before-coding ran, checks code against project rules, compares against the implementation guide, and produces execution-report.md. Run after all code is written and tests pass.

Capture learnings from a completed story before moving on. Asks three questions one at a time and writes a retro draft pending graduation. Run immediately after after-coding.
