fak is a self-hosted agent kernel distributed as a single Go binary. It wraps existing coding-agent sessions without replacing their interface or model, managing shared context, provider cache continuity, session recovery, model routing, tools, policies, and execution receipts.
Tool calls pass through explicit policies that can allow, deny, transform, or witness them. Its default-deny capability floor blocks tools outside the configured allow-list, while the system can forward an existing provider subscription credential, route tasks to a configured provider or its native inference engine, and avoid silent fallbacks. The repository also provides an offline proof mode and installation through a shell script or Go.
