Best Practice Core

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

⛔ CRITICAL: Task Document Format Protection

Best Practice는 서브태스크 아래에 위치하되, Kanban 파서가 태스크로 인식하지 않는 형식을 사용해야 합니다.

❌ FORBIDDEN - 하이픈 리스트 사용:

  - [ ] Design login UI layout
    <!-- Best Practice Tree -->
    - Login UI           ← 파서가 태스크로 오인식!
      - Layout

✅ REQUIRED - 4-space 들여쓰기 + 코드블록 또는 인용블록 사용:

## Worker1

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

Format Rules

Alternative Format (인용블록)

  - [ ] Design login UI layout
    > **BP** · Layout: Mobile-first · Validation: Real-time feedback · Security: No password in URL

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.
