What problem does it solve? Turning a spec or requirements document into an actionable implementation plan is error-prone: tasks end up too vague, placeholders slip in, and engineers without codebase context get stuck. This Skill produces a complete, bite-sized task breakdown that an engineer with zero project context can execute directly. ## Core Features & Use Cases - Structured Plan Documents: Generates plans with a mandatory header (goal, architecture, tech stack, global constraints) and per-task blocks listing exact files to create or modify, interfaces consumed and produced, and checkbox steps. - TDD Bite-Sized Steps: Each task is decomposed into 2-5 minute steps following a test-driven cycle: write failing test, verify failure, implement minimally, verify pass, commit. - Placeholder Prevention and Self-Review: Enforces a no-placeholder policy (no TODOs or vague instructions) and runs a self-review checklist covering spec coverage, placeholder scans, and type consistency across tasks. - Use Case: After brainstorming a feature spec, invoke this Skill to produce a dated plan file under docs/superpowers/plans/, then hand it off to subagent-driven or inline execution workflows. ## Quick Start Ask the AI to use the writing-plans skill to turn your feature specification into a step-by-step implementation plan saved under docs/superpowers/plans/.
