What Plan does

Plan researches the codebase and writes an implementation plan using Propose/Justify/Recommend before any feature, fix, or refactor. It updates task files and stops for approval without changing source code.

Plan is cataloged under AI Engineering on DirSkills. Plan comes from a repository tagged ai, anthropic, architecture, best-practices and claude-code.
