About @Wolfe-Jam
FAF (Focussed AI Format) is an IANA-registered open-source standard for providing persistent project context to AI coding agents. Created by Wolfe-Jam (Wolfe-James), it includes a CLI tool (faf-cli) that automatically generates AGENTS.md, CLAUDE.md, GEMINI.md, and .cursorrules files from a repository's real stack. Additionally, multiple MCP (Model Context Protocol) servers extend support to Claude, xAI Grok, Cursor, and VS Code. The format is registered as application/vnd.faf+yaml and specializes in context, memory, and agents.

FAQ
What is FAF?
FAF (Focussed AI Format) is an IANA-registered open standard for persistent project context that AI coding agents can read. It author files like AGENTS.md, CLAUDE.md, and GEMINI.md from your repository's real stack.
Which AI tools does FAF support?
FAF supports Claude (via claude-faf-mcp), xAI Grok (via grok-faf-mcp), and Cursor/VS Code (via faf-mcp). It also works with Gemini, Copilot, and Codex through the .faf format and faf-skills.
Is FAF free to use?
Yes, all FAF tools and specifications are open-source and free. You can access them on GitHub under the Wolfe-Jam profile.
What is faf-cli?
faf-cli is a command-line tool that scans your repository's real stack and automatically generates AGENTS.md, CLAUDE.md, GEMINI.md, and .cursorrules files in the IANA-registered .faf format.
