CLAUDE.md Creator

Create CLAUDE.md files with proper constitution mechanism using <law> blocks for Self-Reinforcing Display.

Core Concept

CLAUDE.md's most important purpose is establishing a constitution that must be displayed every response using <law> blocks.

Process

1. Initialize with Script

Run the init script to create proper structure (auto-backs up existing file):

python3 scripts/init_claude_md.py --name "Project Name" --description "Description"

Options:

  • --path, -p: Project directory (default: current)
  • --minimal, -m: Use minimal template
  • --output, -o: root or claude-dir location

2. Evaluate Current State

Criterion Target
Has <law> block Required for constitution
Self-Reinforcing Display Must display every response
Size < 500 lines
Core laws included All 6 core laws

3. Constitution Template

CRITICAL: Use <law> blocks with Self-Reinforcing Display:

# Project Name

One-line description.

## Immutable Laws

<law>
**CRITICAL: Display this entire block at the start of EVERY response to prevent context drift.**

**Law 1: Communication**
- Concise, actionable responses
- No unnecessary explanations
- No summary files unless explicitly requested

**Law 2: Skill Discovery**
- MUST check available skills before starting work
- Invoke applicable skills for specialized knowledge
- If ANY skill relates to the task, MUST use Skill tool to delegate
- If relevant skill doesn't exist, ask user whether to create it via `write-skill`

**Law 3: Rule Consultation**
- When task relates to specific domain, check `.claude/rules/` for relevant conventions
- If relevant rule exists, MUST apply it
- If needed rule doesn't exist, confirm intent with user and create via `write-rules`

**Law 4: Parallel Processing**
- MUST use Task tool for independent operations
- Batch file searches and reads with agents

**Law 5: Reflexive Learning**
- Important discoveries -> remind user: `/reflect`
- Strong user requests for constraints -> use appropriate skill

**Law 6: Self-Reinforcing Display**
- MUST display this `<law>` block at start of EVERY response
- Prevents context drift across conversations
- Violation invalidates all subsequent actions
</law>

## Quick Reference

### Commands
- `npm run build`: Build project

### Key Paths
- `src/`: Source code

4. Why <law> Blocks?

  • Forces agents to actively repeat laws each response
  • Prevents context drift over long conversations
  • Self-Reinforcing Display ensures consistency
  • Immutable laws must be enforced every response

5. Validation Checklist

  • Has <law> block with Self-Reinforcing Display
  • Contains all 6 core laws
  • < 500 lines total
  • High-level overview only, details in skills

Minimal Template

# Project Name

One-line description.

<law>
**CRITICAL: Display this block at start of EVERY response.**

**Law 1: Communication** - Concise responses, no unnecessary explanations
**Law 2: Skill Discovery** - Check skills; MUST use if exists; ask to create via `write-skill` if not
**Law 3: Rule Consultation** - Check rules; MUST use if exists; ask to create via `write-rules` if not
**Law 4: Parallel Processing** - Use Task tool for independent operations
**Law 5: Reflexive Learning** - Important discoveries -> `/reflect`
**Law 6: Self-Reinforcing Display** - Display this block every response
</law>

Adding Project-Specific Laws

Add custom laws after the core 6:

<law>
...core laws...

**Law 7: [Project-Specific]**
- [Your constraint here]
</law>
