About
The Plan Directory skill empowers Claude to scaffold and maintain professional-grade project plans within a repository using a standardized file structure. It generates a centralized PLAN.md index and individual, 3-digit numbered task files that include specific goals, checklists, test requirements, and completion criteria. By enforcing strict invariants like mirrored checkbox synchronization and explicit dependency mapping, this skill ensures that complex migrations, feature developments, and refactors remain organized, verifiable, and easy for both human engineers and AI agents to execute efficiently.
