What problem does it solve? Engineers and AI agents often receive vague specs and produce incomplete or inconsistent implementation plans, leading to stalled work, placeholder content, and mismatched interfaces between tasks. This Skill enforces a rigorous plan-writing process so every plan is complete, testable, and executable by someone with zero codebase context. ## Core Features & Use Cases - Structured Plan Documents: Generates plans with a mandatory header (goal, architecture, tech stack, global constraints) saved to docs/superpowers/plans/ with dated filenames. - Bite-Sized TDD Tasks: Breaks work into tasks with exact file paths, interface contracts (consumes/produces), and 2-5 minute steps following the failing-test, implement, verify, commit cycle. - Placeholder Prevention & Self-Review: Forbids TODOs and vague steps, then 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 complete implementation plan that a subagent or junior engineer can execute task-by-task without getting stuck. ## Quick Start Ask the AI to use the writing-plans skill to create an implementation plan for your approved feature spec.
