Generator-evaluator loop that iterates a feature build until it clears a scored rubric threshold.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Overview Run a planner → generator → evaluator loop with a score-gated stop condition. The planner expands the brief into acceptance criteria and a rubric. The generator implements against the criteria. The evaluator scores the result, returns feedback. The loop iterates until the score crosses the threshold or the iteration cap is hit. ## When to use - The output has a measurable quality signal, Playwright test outcome, lint pass, custom rubric. - The first attempt is unlikely to be the last attempt. - The cost of running a feedback loop is justified by the quality lift. ## When NOT to use - One-shot implementations where the spec is unambiguous. - Recurring schedules. Use the `/loop` built-in. - Visual design exploration. Use `/design variants`. - Trivial fixes. Direct edit is faster. ## Arguments `/gan "<brief>"` is the canonical form. The brief is one or two sentences describing what to build. Environment variables: - `GAN_MAX_ITERATIONS` (default 8). Hard cap on planner-generator-evaluator cycles. - `GAN_PASS_THRESHOLD` (default 8.0). Weighted score 0-10 to consider passing. …

How to install
mdr add gufranco/claude-engineering-rules/gan@sha256:afe4fc9f4b8aeb68The line at the top of this page pins the label git:20261012.84ebb18, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
