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

Rule	Constraint
Max depth	3 levels
Max children per node	5 items
Leaf node max length	12 words OR 60 characters
Node format	Noun phrases/keywords ONLY
Duplicates	Merge into single item
Tree format	Markdown tree ONLY (no mixing)

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

markdown

- 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:

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