What is the 'Iron Law' of this skill?

The Iron Law states there is no implementation without a plan first. For any task with 3 or more steps, Claude must generate a detailed markdown plan before writing any production code.

Where does Claude save the implementation plans?

Plans are automatically saved to the `docs/plans/` directory following a date-stamped naming convention (YYYY-MM-DD-feature-name.md) for easy version control and reference.

How does it handle Test-Driven Development (TDD)?

The skill breaks every feature into a cycle: write a failing test, run it to verify failure, write minimal code to pass, verify the pass, and commit. Every step includes the exact code and commands needed.

Can I use this for simple, single-file changes?

While highly recommended for complex tasks, the skill allows you to skip formal planning for single-file, single-function changes where the implementation is trivial.

生産性とワークフロー

Generates granular, TDD-focused implementation blueprints for complex, multi-step software development tasks.

概要

The Implementation Planning skill enforces a structured development methodology by requiring a comprehensive technical plan before any implementation begins. It specializes in breaking down complex features into bite-sized, 2-5 minute tasks that follow a strict Test-Driven Development (TDD) cycle. Each plan provides exact file paths, complete copy-pasteable code, and specific verification commands, ensuring that even the most complex refactors or feature additions are executed with precision and zero ambiguity. By documenting the architecture and tech stack upfront, it helps teams maintain a clean, DRY, and YAGNI-compliant codebase.
