.faf is an IANA-registered structured file (application/vnd.faf+yaml) that captures your project's DNA and generates/syncs your CLAUDE.md — so Claude starts every session already knowing the project.
This plugin bundles the claude-faf-mcp server (also in the official MCP Registry).
/plugin install faf@claude-community
