Test suite performance audit and optimization. Measures baseline timing, audits runner configuration against TP1-TP17 checklist, identifies the slowest tests, and produces an impact-ranked action plan. Modes: full audit (default), baseline (measure only), verify (compare to saved baseline), --no-run (config audit only), --path <dir> (monorepo scope).
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
# zuvo:tests-performance — Test Suite Performance Audit Measurement-driven optimization of the test suite. Establishes a baseline, audits the runner configuration, identifies slow tests, and ranks fixes by expected impact. **Scope:** Test suite speed and runner configuration. Reducing wall-clock time of the test suite. **Out of scope:** Test quality (use `zuvo:test-audit`), flaky/intermittent test investigation (use `zuvo:debug` — it owns reproduction and bisect; `zuvo:fix-tests` repairs known anti-patterns, it does not diagnose nondeterminism), CI pipeline optimization (use `zuvo:ci-audit`), systematic test anti-patterns (use `zuvo:fix-tests`). **This skill does not write.** It measures, scores and proposes exact config diffs; applying them is the user's call. Phase 5 re-measures after *they* have been applied. ## Core Principles 1. **Measure before and after.** No measurement means no improvement claim. 2. **Config changes before code changes.** A 5-minute config fix often outperforms a 2-hour test rewrite. 3. **Rank by impact, not effort.** Present changes in expected-speedup order. 4. **Runner-specific, not generic.** Jest advice for Vitest projects causes harm. …

How to install
mdr add greglas75/zuvo/tests-performance@sha256:39c7d2698cf95e25The line at the top of this page pins the label git:20260829.24037b1, 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.
