What problem does it solve? It turns an already-written, linted SPEC.md into working code one criterion at a time, preventing bloated sessions that try to build an entire feature in a single pass and ensuring every change is test-backed, gated, and committed. ## Core Features & Use Cases - Single-criterion red-green loop: Picks the next unclaimed criterion via the speccle oracle, writes failing token-tagged tests first, then makes them green. - Tracer selection: On a slice with nothing built yet, guides choosing the criterion whose test exercises the thinnest complete path through every layer. - Deterministic checks-gate: Runs lint, claims, verify, and the full project test suite before committing, with a stop rule when a check fails the same way twice. - Use Case: Given a checkout/ feature folder with a linted SPEC.md, ask the agent to implement CHECKOUT-2; it writes the tagged tests, makes them pass, runs the gate, and commits naming the criterion. ## Quick Start Ask the agent to implement the next criterion of the feature folder, for example by saying "implement CHECKOUT-2" or "make the next criterion of the checkout slice green".
