Analyze web performance URLs with the PerfGraph CLI and interpret its deterministic reports, causal chains, and prioritized remediation data. Use when the request names perfgraph, or asks to measure or diagnose loading speed, Core Web Vitals, Lighthouse performance, bottlenecks, or web performance regressions.
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
# PerfGraph CLI Skill version 0.2.0 — matches the `perfgraph` package. A copy of this skill that is older than the installed package gives outdated guidance; check it with `perfgraph --version`. Use this skill when the task requires a fresh synthetic performance analysis or interpretation of an existing PerfGraph run. The CLI is the execution layer; the skill explains how to invoke it and how to read its artifacts. ## Run an analysis Prefer the installed `perfgraph` command: ```bash perfgraph run --url <url> --output ./perfgraph-output --pretty ``` Use `--runs 1` for a quick look, and `--runs 3` when the question is why something is slow. The first run is often an outlier — a cold JIT, a cold DNS, a cold connection — so a single run can be several times worse than the page normally is, and a fix aimed at that outlier is aimed at nothing. `insights.multiRun` says how many runs were collected, which one the report describes, and the median of the lab runs. When it is there, treat the findings of the described run as the cold start unless the median agrees with them, and say which number you quote. The per-run metrics and their spread land in `runs-summary.json` next to the …

How to install
mdr add be1zebub/perfgraph/perfgraph@sha256:85686ef89625faafThe line at the top of this page pins the label v0.2.0, 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.
