Functional
Freebuff has a complete install: npm install -g freebuff, then freebuff inside the repo. No API key on the free tier, with subagents and BYOK. It is free and ad-supported, and prompts may leave the machine for the free models. For a first CLI on a repo you already have, that egress fact sets the score. The install is Functional. The trust model is not Strong.
