A composable TypeScript framework for building reliable LLM agents on a harness you fully control. The same code runs the agent loop on every model tier — local 4B to frontier — with tool-call healing, verification, and durable crash-resume, on a typed 12-phase engine where every step emits an event you can hook into.
