Dev docs system

Creates a structured documentation system for large tasks to maintain context across sessions.

When to invoke

• When starting a large, multi-session task
• When you need to track progress across context compactions
• When working on complex implementations requiring documentation
• Before major refactoring or feature development

Usage

/dev-docs [task-name]

Instructions

When this command runs:

1. Create dev docs directory structure:

   dev/active/[task-name]/
   ├── plan.md      # Strategic implementation plan
   ├── context.md   # Key files, decisions, dependencies
   └── tasks.md     # Detailed task checklist
   

2. Generate plan.md with:

   • Task overview and objectives
   • High-level implementation strategy
   • Key architectural decisions
   • Risk assessment and mitigation
   • Success criteria

3. Generate context.md with:

   • List of key files to modify
   • Important code patterns and conventions discovered
   • External dependencies and their versions
   • Design decisions and rationale
   • Links to relevant documentation

4. Generate tasks.md with:

   • Detailed, actionable task checklist
   • Estimated complexity for each task
   • Dependencies between tasks
   • Progress tracking checkboxes

5. Update TodoWrite with the initial tasks

Notes

• Run /update-dev-docs before session compaction to capture progress
• Keep context.md updated as you discover new information
• Check off tasks in tasks.md as you complete them
