Audit and prioritize performance work through bounded-work and forward-progress checks. Use when asked to find performance issues, investigate freezes/500s/OOMs, review retries or polling for no-progress loops, rank a performance backlog, or implement the next simple performance fixes.
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
# Audit Performance Find work that grows without a useful bound or repeats without progress. Produce an evidence-backed ledger or report, then prefer the smallest fix that preserves recovery. ## Workflow 1. **Trace hot paths.** Find recurring syncs, polls, streams, retries, queues, scheduled jobs, filesystem walks, and request-time reads. Follow each through its production caller; ignore test-only paths. 2. **Compute the amplification.** State the trigger and worst-case work in concrete units: rows, queries, pages, entries, bytes, jobs, retries, or full-file rewrites. Distinguish a bounded large constant from work that grows with history, tenants, paths, or outage duration. 3. **Check forward progress.** For every retry, fixed-prefix batch, cutoff, or transitional poll, identify what changes before the next attempt. If nothing must change, it can loop or starve forever. Check that partial fixes do not merely delay the same work. 4. **Falsify severity.** Inspect existing caps, indexes, backoff, deadlines, healing owners, and caller frequency. Dismiss findings already bounded cheaply enough or continuously healing. …

How to install
mdr add dzhng/skills/audit-performance@sha256:4904d5c24de53f43The line at the top of this page pins the label git:20261002.8aea537, 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.
