Diagnose web-app performance across build, server, browser, database, and network paths. Use when investigating slowness, resource spikes, reload loops, regressions, bloat, or poor Web Vitals.

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 diagnosis

Measure a reproducible slow path before changing it. Diagnosis does not authorize a fix unless the user requested implementation.

## Workflow

1. Establish the symptom, affected environment, route/action, regression window, expected threshold, and a repeatable reproduction. Infer these from traces/issues/code when possible; ask only for missing facts that change the investigation.
2. Detect framework/runtime/version, deploy topology, package manager, data stores, observability, and recent relevant diffs. Separate development-only behavior from production behavior.
3. Attribute resource symptoms before profiling the application. For heat, fan, battery, or system-wide spikes, use a short, thermally safe reproduction and sample process CPU, memory, energy, and GPU where available. Isolate the browser tab from extensions, the Node/dev server, compiler watchers, database, and unrelated processes. Stop the reproduction if temperature, power draw, or system stability becomes unsafe.
4. Capture a baseline with the tool suited to the symptom:
   - dev/build: timed cold and warm start/build, compiler logs, watcher scope;

How to install

The exact contents, by fingerprint
mdr add tushaarmehtaa/tushar-skills/performance-diagnosis@sha256:aa59875f97c63327

The line at the top of this page pins the label git:20260807.fac9f85, 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.
