Faf

FAF is an open standard and tool for defining persistent, structured context for AI models, agents, and tools. It uses a single YAML file (.faf) to organize every 'slot' or piece of context your AI needs, enabling accurate, contextually-grounded, and drift-free operation across sessions, tools, teams, and enterprises. FAF supports bi-directional sync with other instruction formats (like .md) and integrates with major Model Context Protocol (MCP) servers and AI platforms such as Claude, Grok, Gemini, VS Code, and more. Ideal for developers and teams needing reliable, persistent context in their AI workflows.
