The 3Ws โ 3 Answers. That's It.
Every great product started with 3 answers to the 3Ws โ 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 โ For Optimized AI
3Ws gets you started. For fully optimized AI, complete the set โ 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 โ 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 โ 3 answers โ project.faf โ AI reads it โ every session โ forever
project.faf โโโ 8ms โโโ CLAUDE.md (bi-sync, free)
project.faf โโโ 8ms โโโ MEMORY.md (tri-sync, Pro ๐)Claude does the rest. Zero-effort, right first time, fast, accurate, done. Language, framework, package manager, build tools โ all auto-detected from your existing files. The human context is the part only you can give.
