What problem does it solve? It turns a signed work brief into a delivered milestone without human micromanagement: an executor session runs a goal loop against pre-written acceptance tests, records every decision it made alone, and stops cleanly when the brief contradicts reality instead of guessing. ## Core Features & Use Cases - Goal-loop execution: Re-checks the brief's Blocking acceptance criteria each turn and continues until they hold, treating acceptance tests as read-only contract. - Escape valve for contradictions: When a stated fact is false or a test contradicts its job, it writes a divergence report from the bundled template, marks the milestone diverged, and stops for planner triage. - Structured PR delivery: Produces one PR per milestone with the spec mapping line, blocking test output, and three mandatory sections — Decisions I made alone, For the human, Facts I corrected. - Use Case: Point it at docs/specs/reminders/briefs/M1-storage.md; it sets the spec row to in progress, implements until the blocking tests pass, runs a fresh-context self-review, and opens a PR ready for /kbabysit review rounds. ## Quick Start Ask the AI to run kbuild on a work brief such as docs/specs/reminders/briefs/M1-storage.md and implement the milestone until its blocking tests pass.
