faf-expert

name	faf-expert
description	Expert in .faf (Foundational AI-context Format) files for persistent project context. Use when working with .faf files, project DNA, CLAUDE.md bi-sync, faf-cli commands, MCP server configuration, or AI-readiness scoring (0-100%). Updated for v2.8.0 Tool Visibility System.

FAF Expert - Project DNA Specialist

What is .faf?

.faf is the universal format for persistent AI project context - "Project DNA ✨ for ANY AI".

Core Concepts:

• Foundational AI-context Format - YAML-based project context file
• Persistent Context - Survives across sessions, tools, and AI assistants
• Universal - Works with Claude, ChatGPT, Gemini, Cursor, any AI
• Measurable - Championship scoring system (0-100% AI-readiness)
• Official Anthropic MCP Steward - PR #2759 MERGED

When to Use This Skill

Activate this skill when:

• Creating or updating .faf files
• Working with CLAUDE.md files
• Running faf CLI commands (init, auto, score, formats, bi-sync)
• Scoring project AI-readiness
• Setting up MCP server (claude-faf-mcp)
• Configuring tool visibility (v2.8.0+)
• Discussing project context or documentation

Key Files

• .faf - YAML format, machine-readable project context
• CLAUDE.md - Markdown format, human-readable project guide
• Bi-Sync - .faf ↔ CLAUDE.md kept in sync automatically
• project.faf - v1.2.0 standard naming

Common Commands

faf-cli Commands

faf init              # Create .faf from project
faf auto              # Auto-detect stack and create .faf
faf score             # Rate AI-readiness (0-100%)
faf formats           # List 153+ supported formats
faf bi-sync           # Sync .faf ↔ CLAUDE.md
faf status            # Check project AI-readiness
faf validate          # Validate .faf structure
faf doctor            # Diagnose and fix issues
faf migrate           # Migrate to latest format

.faf File Structure

# Basic .faf structure
format: typescript-nextjs
language: typescript
framework: nextjs
version: "14.0.0"

structure:
  - src/
  - components/
  - pages/

dependencies:
  react: "^18.0.0"
  next: "^14.0.0"

testing: jest
deployment: vercel

# v1.2.0+ additions
project_name: "My Project"
ai_readiness_score: 87

Best Practices

1. Start with faf auto - Let it detect your stack
2. Review and refine - Auto-detection is 85% accurate, tweak as needed
3. Run faf score - Target 85%+ for championship context
4. Use faf bi-sync - Keep .faf and CLAUDE.md in sync
5. Update regularly - As project evolves, update context
6. Use core tools first - Advanced tools are opt-in for specific needs

{
  "mcpServers": {
    "faf": {
      "command": "npx",
      "args": ["-y", "claude-faf-mcp@latest"]
    }

v2.8.0 Tool Visibility System

Problem Solved: Reduced cognitive load from 51 tools to 21 core tools.

How It Works:

• Default: Shows 21 essential tools
• Opt-in: Enable all 51 tools via environment variable
• Smart Filtering: Tools categorized by purpose
• Backward Compatible: Existing setups continue working

Categories:

• workflow - Essential commands
• quality - Scoring and validation
• intelligence - Format/stack detection
• sync - Context synchronization
• ai - AI enhancement features
• help - Documentation
• trust - Trust validation
• file - File operations
• utility - Misc tools

Configuration Priority:

1. Environment variable (FAF_MCP_SHOW_ADVANCED)
2. Config file (~/.fafrc)
3. Default (core only)

Troubleshooting

MCP Server Not Loading

# Check logs
tail -f ~/Library/Logs/Claude/mcp-server-claude-faf-mcp.log

# Verify config
cat ~/Library/Application\ Support/Claude/claude_desktop_config.json

# Test locally
node /path/to/claude-faf-mcp/dist/src/index.js

Tool Count Verification

# Should show 21 core tools (default)
# Or 51 tools (advanced mode)
# Check console output when MCP loads

CLI Not Found

# Install globally
npm install -g faf-cli

# Or via Homebrew
brew install faf-cli

# Verify installation
faf --version

Advanced Usage

Custom Config File

Create ~/.fafrc:

{
  "showAdvanced": true
}

Or key=value format:

FAF_SHOW_ADVANCED=true

Local Development

# Use local build
{
  "mcpServers": {
    "faf": {
      "command": "node",
      "args": ["/path/to/claude-faf-mcp/dist/src/index.js"],
      "env": {
