Measures and improves performance against budgets — Lighthouse (mobile) / Core Web Vitals, bundle analysis, API p95 with k6, DB EXPLAIN, Go/PHP profiles, game frame/draw-call/memory; ranks fixes by impact; writes docs/ops/perf-audit-<date>.md. Required before release.

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

# Perf Audit

Reply in the project conversation language (CLAUDE.md → Language); code, identifiers, paths and commit messages stay in English.

Budgets — `technical-preferences.md` § Performance budgets; references `stack-reference/web-platform.md`, `database.md`, `graphql.md`, `threejs-webgames.md`; template `findings.md`. In the commands below, `<hooks>` is `.claude/hooks/` in copy mode and `${CLAUDE_PLUGIN_ROOT}/hooks/` in plugin mode.

**No budgets** — the section is missing or still holds `[N]` placeholders → the audit is not blocked: the Core Web Vitals defaults of `web-platform.md` (LCP / INP / CLS at p75 mobile, TTFB, initial JS) are the budget for the web metrics, the Phase 2 table says so in a note ("budget: CWV default, none recorded"), API/DB/game metrics with no default are reported as `NO BUDGET` (measured, not judged), and the report proposes recording the budgets in `technical-preferences.md` (`/setup-stack` / `/adopt` field). A missing budget is never silently replaced by a guess.

## Phase 1: Baseline (Bash, whatever is available)

How to install

The exact contents, by fingerprint
mdr add gonimar/claude-web-studio/perf-audit@sha256:a5946abf1684c31d

The line at the top of this page pins the label git:20260927.54cdcbc, 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.
