Use this before any creative work — creating features, building components, adding functionality, or modifying behavior. Explores intent and design before implementation. Use this skill whenever the user describes something they want to build, change, or improve, even if they don't say 'brainstorm' — phrases like 'I want to add X', 'let's build Y', 'we need a way to Z', or 'help me design' all apply.
Review a completed requirement's code — trace the logic, check spec alignment against the acceptance criteria, fix code smells, and run a production hazard check. Runs after each requirement in pwk-executing-tasks. Unlocked: may edit code to apply smell fixes.
Use after all requirements are complete to delete consumed plan docs, curate lessons, update documentation, and ship the work.
Turn a design doc's requirements into a behavioral spec — acceptance criteria + integration tests per requirement. Use after pwk-brainstorming, before pwk-executing-tasks. Use when the user says 'let's plan', 'write a plan', 'break this down', or after a brainstorm when ready to move to implementation.
Disciplined debugging loop for hard bugs and performance regressions. Use when a test fails unexpectedly, a bug is found during execution, or something is broken. Use this skill whenever the user reports a bug, says 'this doesn't work', 'something's wrong', 'help me debug', or when tests fail for unclear reasons. Works at any point in the workflow — brainstorm, execute, or standalone.
Implement a plan requirement-by-requirement with test-first discipline and full autonomy. Run after pwk-writing-plans. Each requirement: write integration tests (red) → checkpoint → implement to green → checkpoint → pwk-code-review.
Show all active pipeline topics and their phase/progress. Use when the user asks 'where are we', 'status', 'what's in flight', or when resuming and unsure which design to continue. Read-only discovery. Not a pipeline phase.
