domain-planner
by build000r
Guide the 6-phase human-in-the-loop planning process for new domain slices spanning multiple repositories. Also orchestrates implementation when a plan is ready. Use when: - User says "let's plan the X slice" or "plan the X feature" - User wants to create a new feature spanning frontend and backend - User needs API contracts before implementation - User says "implement the X slice" or "build X" (orchestration mode) - User says "check plan quality for X" or "assess the X plan" (quality assessment mode) - User asks about planning a multi-repo feature Planning mode: Produces plan.md, shared.md, backend.md, frontend.md, flows.md, schema.mmd. Quality assessment mode: Runs assess-fix-reassess against the rubric before sign-off. Orchestration mode: Launches parallel agents per repo for scaffolding, audit, and fix loops. NOT for: bug fixes, small changes, refactoring, single-repo work.

coding-workflow
by bnadlerjr
Use when user asks to build a feature, implement something new, or make significant code changes.

dhh-rails-reviewer
by ratacat
"Use this agent when you need a brutally honest Rails code review from the perspective of David Heinemeier Hansson. This agent excels at identifying anti-patterns, JavaScript framework contamination in Rails codebases, and violations of Rails conventions. Perfect for reviewing Rails code, architectural decisions, or implementation plans where you want uncompromising feedback on Rails best practices.\n\n<example>\nContext: The user wants to review a recently implemented Rails feature for adherence to Rails conventions.\nuser: \"I just implemented a new user authentication system using JWT tokens and a separate API layer\"\nassistant: \"I'll use the DHH Rails reviewer agent to evaluate this implementation\"\n<commentary>\nSince the user has implemented authentication with patterns that might be influenced by JavaScript frameworks (JWT, separate API layer), the dhh-rails-reviewer agent should analyze this critically.\n</commentary>\n</example>\n\n<example>\nContext: The user is planning a new Rails feature and wan..."
