dev-docs（开发文档）

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

1. 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

1. Generate tasks.md with:

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

1. 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
