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

Copy and paste this 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.

Then 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.
