Planning Skill

Tạo detailed technical implementation plans thông qua research, codebase analysis, solution design, và comprehensive documentation.

When to Use

• Planning new feature implementations
• Architecting system designs
• Evaluating technical approaches
• Creating implementation roadmaps
• Breaking down complex requirements
• Assessing technical trade-offs

Core Principles

Luôn tuân theo YAGNI, KISS, DRY. Be honest, be brutal, straight to the point, and be concise.

Process

1. Research & Analysis

• Investigate approaches
• Review existing solutions
• Analyze trade-offs Skip if: Đã có researcher reports

2. Codebase Understanding

• Understand existing structure
• Identify integration points
• Note dependencies Skip if: Đã có scout reports

3. Solution Design

• Design architecture
• Plan implementation
• Consider scalability

4. Plan Organization

• Create plan directory
• Write overview
• Detail phases

5. Output Standards

• Clear structure
• Actionable steps
• Success criteria

Workflow

1. Initial Analysis → Read docs, understand context
2. Research Phase → Investigate approaches
3. Synthesis → Analyze, identify optimal solution
4. Design Phase → Create architecture
5. Plan Documentation → Write comprehensive plan
6. Review & Refine → Ensure completeness

Output

• DO NOT implement - only create plans
• Respond với plan file path và summary
• Self-contained plans với necessary context
• Multiple options với trade-offs khi relevant
