Hokmah

Hokmah gives AI coding agents persistent architectural memory through three graph structures: TransitionGraph (Markov model of which files change together), IdeaGraph (16 relation types between concepts), and WorldModel (file tree and dependencies). You connect a GitHub repo, it builds the graph, then you can analyze refactoring impact without sending your whole codebase to an LLM. The free tier includes impact analysis with risk scores and affected files. Pro tier adds test and code generation that uses 40x fewer tokens by traversing the graph instead of dumping context. Works over streamable-http, so no local installation needed unless you want to self-host against your own Hokmah backend.
