Tell AI what you're building, who it's for, and why it matters. 30 seconds. 🐘 It never forgets.
FAF defines. MD instructs. AI codes.
🐘 tri-sync now free for all builders —
.faf↔CLAUDE.md↔MEMORY.mdin one command. Pro feature. Now free.
⚡ New:
/fafprompt — type/fafin Claude Desktop. It checks your project, scores it, drives it to 100%, and syncs. Relentlessly. One command.
32 MCP tools. 1 prompt. IANA-registered format (application/vnd.faf+yaml). 2,346 test executions per push.
The 3Ws — 3 Answers. That's It.
Every great product started with 3 answers to the 3Ws — Who, What, Why:
| WHO is it for? | WHAT does it do? | WHY build it? | |
|---|---|---|---|
| Uber | People who need a ride | Tap a button, car arrives | Taxis were broken |
| Airbnb | Travelers who can't afford hotels | Stay in someone's spare room | Millions of empty rooms exist |
| Slack | Teams drowning in email | Organized group messaging | Decisions buried in threads |
| Venmo | Friends splitting bills | Send money instantly | Someone always forgets to pay back |
Same pattern. Every product that works starts here. .faf captures it:
human_context:
who: "people who need a ride across town"
what: "tap a button, car arrives in minutes"
why: "taxis are slow, expensive, and hard to find"
30 seconds. Claude builds your project.faf from this. Every session after, AI starts smart.
The 6Ws — For Optimized AI
3Ws gets you started. For fully optimized AI, complete the set — Where, When, How:
where: "mobile app, iOS and Android" # where does it live?
when: "launch in 3 months" # when is it shipping?
how: "GPS matching, real-time pricing" # how does it work?
3Ws initiates the project with AI. 6Ws optimizes AI to 100%. Same YAML, same file. More examples → faf.one/ideas
Quick Start
One-click install — Claude Desktop
⬇ Download claude-faf-mcp-5.5.1.mcpb
Double-click the downloaded file. Claude Desktop installs it automatically. No terminal. No JSON config. 32 tools live in 10 seconds.
Or — copy-paste to Claude
Install the FAF MCP server:
npm install -g claude-faf-mcp, then add this to my claude_desktop_config.json:{"mcpServers": {"faf": {"command": "npx", "args": ["-y", "claude-faf-mcp"]}}}and restart Claude Desktop.
Or — manual npm install
npm install -g claude-faf-mcp
Add to claude_desktop_config.json:
{
"mcpServers": {
"faf": { "command": "npx", "args": ["-y", "claude-faf-mcp"] }
}
}
Restart Claude Desktop.
Then
Type /faf — Claude checks your project, scores it, drives it to 100%, and syncs. Done.
Or tell Claude your 3Ws: "I'm building [what] for [who] because [why]"
How It Works
You → 3 answers → project.faf → AI reads it → every session → forever
project.faf ←── 8ms ──→ CLAUDE.md (bi-sync, free)
project.faf ←── 8ms ──→ MEMORY.md (tri-sync, Pro 🐘)
Claude does the rest. Zero-effort, right first time, fast, accurate, done. Language, framework, package manager, build tools — all auto-detected from your existing files. The human context is the part only you can give.
Scoring: From Blind to Optimized
| Tier | Score | What it means |
|---|---|---|
| 🏆 Trophy | 100% | Gold Code — AI is optimized |
| 🥇 Gold | 99%+ | Near-perfect context |
| 🥈 Silver | 95%+ | Excellent |
| 🥉 Bronze | 85%+ | Production ready |
| 🟢 Green | 70%+ | Solid foundation |
| 🟡 Yellow | 55%+ | AI flipping coins |
| 🔴 Red | <55% | AI working blind |
| 🤍 White | 0% | No context at all |
At 55%, AI guesses half the time. At 100%, AI knows your project. Same compiler as faf-cli — same score everywhere.
