# Planning Methodology Skill Systematic approach for creating minimal, reversible implementation plans after research phase. ## Auto-Invoke Triggers - After ResearchPack is validated (score >= 80) - Before code implementation begins - When task requires multi-file changes - User requests implementation plan ## 5-Step Methodology ### Step 1: ResearchPack Review (30 sec) - Verify ResearchPack score >= 80 - Extract required APIs and methods - Note all gotchas and caveats - List open questions ### Step 2: Codebase Analysis (60 sec) - Find existing patterns to follow - Identify files to modify - Check for similar implementations - Map component dependencies ### Step 3: Change Mapping (60 sec) - List all files to modify/create - Define minimal change set - Identify dependencies between changes - Plan test coverage ### Step 4: Risk Assessment (30 sec) - Identify potential failure points - Assess impact on existing code - Define rollback per change - Flag breaking changes ### Step 5: Plan Documentation (60 sec) - Write structured ImplementationPlan - Include verification per step - Document rollback procedure - Define success criteria ## Output Format: ImplementationPlan ```markdown ## ImplementationPlan: [Feature] ### Scope - Files to modify: X - New files: Y - Tests to add: Z ### Changes | # | File | Action | Verification | |---|------|--------|--------------| | 1 | path/file.ts | MODIFY | type-check | | 2 | path/new.ts | CREATE | builds | ### Steps 1.
