Optimizes code, queries, and features based on actual usage by removing unused fields, aggregations, JOINs, and unused complexity. Use when the user invokes /optimize or asks to slim queries to what the UI actually uses.
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
TARGET: - Optimize code/queries/features based on ACTUAL usage, not assumptions - Remove everything that's not needed - Question every field, query, feature, and piece of complexity ALGORITHM: 1. **Audit actual usage**: - Grep/search codebase for each field/query/feature usage - Check UI components - what fields are actually rendered? - Check queries - what fields are actually selected? - Check APIs - what data is actually returned? 2. **Remove aggressively**: - Delete unused fields from SELECT queries - Remove expensive aggregations if not displayed - Drop unused exports, functions, components - Eliminate unnecessary JOINs, GROUP BYs, subqueries 3. **Optimize for reality**: - Base SELECT on actual UI needs (not "might need later") - Use scalar subqueries instead of JOINs when possible - Remove fields only used for filtering (keep in WHERE, remove from SELECT) - Cache only what's actually accessed frequently 4. **Simplify ruthlessly**: - If it's expensive and not used → remove it - If it's "nice to have" → remove it - If it adds complexity without clear benefit → remove it …

How to install
mdr add illyism/dev-skills/optimize@sha256:ef36c52c97f14164The line at the top of this page pins the label v1.0.0, 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.
