MUST USE when investigating or fixing performance issues: slow responses, high memory usage, CPU spikes, throughput degradation, or optimization requests. Enforces measure-first methodology — profile before guessing, baseline before fixing, re-measure after every change. Distinct from systematic-debugging (which changes behavior to fix bugs) and brainstorming (which designs new features). Triggers on: "slow", "performance", "optimize", "speed up", "latency", "throughput", "memory leak…

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

# Performance Investigation

Measure first. Guess never. Fix once.

## Why This Exists

Performance intuition is wrong more often than it's right. Developers consistently misidentify bottlenecks — optimizing the wrong function, caching the wrong query, parallelizing the wrong loop. This skill enforces a measurement-first approach that ensures you fix what's actually slow, not what feels slow.

## Phase 1: Baseline

Before changing anything, establish a quantitative baseline.

1. **Define the metric.** What specifically is slow? Be precise:
   - Response time for endpoint X under Y concurrent users
   - Time to render component Z with N items
   - Memory usage after processing M records
   - Build time for the full project
   
   "It's slow" is not a metric. "GET /api/users takes 1200ms p95 with 100 concurrent connections" is.

2. **Measure the current state.** Run the measurement 3+ times to confirm it's stable and reproducible. For long-running measurements (>2 min each), 2 runs within 5% of each other is sufficient. Record:
   - The metric value (with units)
   - The measurement method (tool, command, conditions)
   - The environment (machine, load, data size)

How to install

The exact contents, by fingerprint
mdr add brunob54/superpowers-orchestrator/performance-investigation@sha256:ba25aadee5471fcd

The line at the top of this page pins the label git:20260415.0a78a70, 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.
