What is a Plans.md file?

Plans.md is a structured task list generated by this skill that Claude Code uses to execute development cycles autonomously via the /work command.

How does it handle feature prioritization?

It generates a priority matrix that classifies tasks as Required, Recommended, or Optional, helping developers manage scope and effort.

What is the 2-agent mode mentioned in the documentation?

It allows you to use one AI (like Cursor) for the initial planning phase and hand off the structured plan to Claude Code for high-performance implementation.

Can I use this with non-technical requirements?

Absolutely. The skill can auto-invoke a 'vibecoder-guide' to assist non-technical users in refining their ideas into technical requirements.

Does this skill support TDD?

Yes, it includes a TDD adoption judgment and test design phase to ensure code quality from the start of the planning process.

生産性とワークフロー

Transforms vague ideas and requirements into structured, executable implementation plans with built-in TDD and quality markers.

The Planning Skill acts as a sophisticated architect for your Claude Code projects, automating the transition from high-level concepts to actionable development tasks. It orchestrates a comprehensive pre-coding phase that includes requirement gathering, technical research via WebSearch, and the generation of a priority-ranked feature matrix. By producing a specialized 'Plans.md' file, it creates a seamless bridge to the implementation phase, ensuring that every line of code is backed by a clear strategy, Test-Driven Development (TDD) principles, and security-focused quality markers.
