/my_plan

/my_plan - Implementation Planning

Create detailed, actionable implementation plans before coding.

Usage

/my_plan [feature description]
/my_plan --tdd [feature description]

Arguments

• --tdd - Enable TDD mode (each task includes RED-GREEN-REFACTOR structure)
• [feature description] - What you want to build

Examples

/my_plan add user authentication with JWT
/my_plan --tdd implement order management system
/my_plan migrate users table to new schema
/my_plan add real-time notifications with WebSockets

What Happens

1. Parse Arguments

   • Check for --tdd flag
   • Extract feature description
   • Detect if project uses TDD by default

2. Spawn Planner Agent

   • Uses Opus model for deep reasoning
   • Has access to all project tools and MCP servers (including Serena)

3. Codebase Analysis

   • Explores project structure
   • Identifies patterns and conventions
   • Finds related existing code
   • Maps dependencies

4. Design Solution

   • Breaks feature into phases
   • Creates atomic, verifiable tasks
   • Includes verification steps
   • Adds TDD structure if enabled

5. Create Plan File

   • Saves to .claude/plans/{timestamp}-{slug}.md
   • Returns summary for user approval

Plan Location

Plans are saved to:

.claude/plans/{YYYYMMDD}-{HHMMSS}-{slug}.md

Example: .claude/plans/20260126-143000-user-authentication.md

Next Steps After Planning

1. Review the plan - Check the generated plan file
2. Approve - Type "approve" to mark ready for execution
3. Execute - Run /my_execute [plan-file] to implement

Rules

• Plans include specific file paths for all tasks
• Every task has a verification step
• TDD mode adds RED-GREEN-REFACTOR to each implementation task
• Planner asks clarifying questions rather than assuming
• No time estimates (focus on what, not when)

Workflow Integration

/my_plan → Review → Approve → /my_execute
