What problem does it solve? Multi-step coding tasks often fail because agents jump into code without a structured plan, producing inconsistent types, missed requirements, and vague steps. This Skill turns a spec or requirements document into a complete, reviewable implementation plan before any code is touched. ## Core Features & Use Cases - Bite-Sized Task Decomposition: Breaks work into 2-5 minute steps following TDD: write failing test, verify failure, implement minimally, verify pass, commit. - Zero-Placeholder Enforcement: Every step contains exact file paths, complete code blocks, exact commands with expected output, and explicit rejection of TODOs or vague instructions. - Self-Review and Execution Handoff: Includes a spec-coverage and type-consistency checklist, then offers subagent-driven or inline execution with review checkpoints. - Use Case: Given a spec for a health/damage system in a Godot game, produce a plan saved to .summer/plans/ with GUT test code, GDScript implementations, and commit steps that a fresh engineer or subagent can execute task-by-task. ## Quick Start Ask the agent to use the writing-plans skill to turn your spec into an implementation plan saved under .summer/plans/ before writing any code.
