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 file lists, interfaces, and checkbox steps. - Bite-Sized TDD Tasks: Each task is decomposed into 2-5 minute steps following a write-failing-test, verify-failure, implement, verify-pass, commit cycle. - Placeholder Prevention & Self-Review: Enforces concrete code in every step and runs a self-review checklist for spec coverage, placeholder scans, and type consistency across tasks. - Execution Handoff: Offers subagent-driven or inline execution paths after the plan is saved to docs/superpowers/plans/. - Use Case: Given a feature spec for a new API endpoint, produce a dated plan file where each task lists exact files to create or modify, test code, run commands, and commit messages. ## Quick Start Ask the AI to use the writing-plans skill to create an implementation plan from your spec before writing any code.
