Best Practice Core

Extracts core best practices for a topic and formats them as a minimal, keyword-focused tree.

Purpose

Extract essential best practices for implementation tasks and format them as ultra-concise tree structures for quick reference during development.

When to Use

Invocation Timing:

• During task planning phase (before implementation)
• When writing subtasks in Docs/{name}_Task.md documents
• BEFORE Worker agents start implementation

Output Location:

• Written directly under each subtask in Task document
• Acts as quick reference for developers/agents

Output Rules (STRICT ENFORCEMENT)

Format Constraints

Zero Tolerance Items

❌ FORBIDDEN:

• Intro paragraphs, conclusions, or commentary
• Full sentences in leaf nodes
• Explanatory text outside the tree
• Mixed tree formats (ASCII + Markdown)
• Depth > 3 or children > 5
• Duplicate items

✅ REQUIRED:

• ONLY output the tree structure
• Use noun phrases: "Error boundary setup", "State validation logic"
• Keep leaf nodes concise: max 12 words
• Merge similar concepts
• Single tree format (Markdown bullets)

Example Output

Topic: Implementing User Authentication

- User Authentication
  - Security
    - Password hashing (bcrypt/argon2)
    - JWT token management
    - HTTPS-only cookies
  - Validation
    - Input sanitization
    - Email format check
    - Rate limiting
  - Error Handling
    - Failed login attempts tracking
    - Account lockout mechanism
    - Clear error messages (no data leaks)

Workflow

When invoked with a topic:

1. Identify Core Areas: Extract 2-5 main categories for the topic
2. Extract Best Practices: For each category, list 2-5 key practices
3. Format as Keywords: Convert to noun phrases (no full sentences)
4. Verify Constraints: Check depth ≤ 3, children ≤ 5, length ≤ 12 words
5. Merge Duplicates: Combine similar/overlapping items
6. Output Tree ONLY: No intro, no conclusion, just the tree

Integration with Task Documents

Example Task Document Integration:

## Worker1

- [ ] Implement user authentication #auth !high Deadline(2025:01:15)
  - [ ] Design login UI layout
    <!-- Best Practice Tree -->
    - Login UI
      - Layout
        - Mobile-first responsive design
        - Focus management (accessibility)
        - Password visibility toggle
      - Validation
        - Real-time feedback
        - Clear error states
      - Security
        - No password in URL params
        - Auto-logout on idle
  - [ ] Create API integration
    <!-- Best Practice Tree -->
    - Auth API Integration
      - Request Handling
        - Token refresh logic
        - Retry with exponential backoff
      - Error Handling
        - Network failure graceful degradation
        - 401/403 redirect to login
      - Security
        - Secure token storage
        - XSS/CSRF protection

Usage Notes

• Concise over Complete: Focus on critical practices, not exhaustive lists
• Actionable Keywords: Use phrases developers can immediately act on
• Context-Aware: Tailor to the specific subtask context (UI vs API vs DB)
• No Duplication: If practice applies to multiple subtasks, mention once in parent

Common Topics

Remember: Output ONLY the tree. No explanations.
