Autonomous metric-optimization loop - run N bounded iterations against a mechanical metric, commit each attempt, auto keep/discard on the number, revert regressions. Use to improve a measurable metric: test coverage, bundle size, lint/type-error count, p95 latency, LOC. Triggers: 'drive coverage up', 'reduce bundle size', 'get lint errors to zero', 'optimize <metric> over iterations', 'keep/discard loop'.
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
# optimize-loop > Constraint + mechanical metric + fast verification = autonomous improvement. `vd:optimize-loop` **optimizes a number** over N bounded iterations (default 10), git-committing each attempt. It does not pursue subjective goals (`vd:auto-loop` / `vd:cook`) and does not poll on a clock (`/loop`). Each iteration makes one atomic change, commits it, measures, and keeps or reverts on the metric. Use it for coverage, bundle size, lint/type errors, latency, or LOC - anything with a consistent numeric evaluator; a known-root-cause bug goes to `vd:fix` / `vd:debug` instead. ## Configuration Parsed from the user message. Missing required fields trigger a single batched `AskUserQuestion` in Claude Code (Goal, Scope, Verify, plus optional Guard); ask the same questions in plain text elsewhere. ### Required | Field | Description | Example | |---|---|---| | `Goal` | Human description of what to improve | `Increase coverage in src/utils` | | `Scope` | Glob(s) for editable files | `src/utils/**/*.ts` | | `Verify` | Shell command printing **a single number** to stdout | `npx vitest run --coverage … \| tail -1` | ### Optional | Field | Default | Description | |---|---|---| …

How to install
mdr add vanducng/skills/optimize-loop@sha256:a1de089be6959056The line at the top of this page pins the label v0.2.0, 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.
