planning-phase

This skill orchestrates the /plan phase, which runs after /spec (or /clarify) and before /tasks in the feature workflow.

Core responsibilities:

• Load all 8 project documentation files from docs/project/ for constraint extraction
• Search codebase for similar features and reusable components (expect 5-15 opportunities)
• Design architecture with components, layers, and design patterns
• Plan data model with entities, relationships, and migrations
• Define API contracts in OpenAPI format (if applicable)
• Plan testing strategy (unit, integration, E2E)
• Estimate complexity (20-30 tasks predicted)

Inputs: spec.md (feature specification), docs/project/*.md (8 files), existing codebase Outputs: plan.md (implementation plan), research.md (reuse findings and project context) Expected duration: 1-3 hours
