Writing Plans

Write comprehensive implementation plans assuming zero codebase context. Document: which files to touch, code, testing, docs, how to test. Bite-sized tasks. DRY. YAGNI. TDD. Frequent commits. Assume skilled developer, minimal domain knowledge, weak test design.

Announce at start: "I'm using the writing-plans skill to create the implementation plan." Context: Run in a dedicated worktree (created by brainstorming skill). Save plans to: docs/plans/YYYY-MM-DD-<feature-name>.md using the Write tool. NEVER write to ~/.claude/plans/ — ignore the plan mode default path. REQUIRED: Before ExitPlanMode, run Plan Verification Checklist, then rule-of-five-plans. Verify what before polishing how -- scope errors caught early save wasted polish on deleted tasks.

Mandatory Tasks (Enforcement)

Create these 7 native tasks at plan start (each blocked by previous via addBlockedBy). Cannot call ExitPlanMode with pending tasks:
