Tooling for the creo-perf skill: deterministic benchmark scripts (scenario captures with EXPLAIN medians and p50/p95 HTTP loops, Lighthouse initial-load audit, platform and schema audits, pg_stat_statements workload discovery, auto-rebuilt before/after dashboard) plus the project scaffolder used by /creo perf init. Not invoked directly; creo-perf routes to it.
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
# creo-perf-harness
This directory holds the executable half of the `creo-perf` skill. It has no
commands of its own: `/creo perf ...` loads `creo-perf` (the playbook), which
runs these scripts.
| Script | Role |
|---|---|
| `scripts/init-project.sh` | scaffold `.claude/skills/creo-perf/` in a project from `templates/` |
| `scripts/preflight.sh` | tools, targets, scenarios, SQL mode sanity |
| `scripts/audit-all.sh <label>` | every capture in the configured order + workload window |
| `scripts/audit-scenario.sh <id> <label>` | one scenario: EXPLAIN medians, HTTP loops, wire bytes, ETag replay, FE probe |
| `scripts/audit-fe.sh <label>` | served assets, production build, bundle composition, Lighthouse xN |
| `scripts/audit-platform.sh <label>` | backend process facts + PostgreSQL settings (context, not metrics) |
| `scripts/audit-schema.sh <label>` | tables, columns, indexes, hypopg verdicts, PostGIS shape |
| `scripts/observability-setup.sh` | pg_stat_statements + auto_explain (+hypopg); restarts the DB |
| `scripts/workload-{pre,drive,post}.sh` | discovery window: reset, drive scenario traffic, rank hot queries |

How to install
mdr add oyusypenko/creo/creo-perf-harness@sha256:dd151207b58c277dThe line at the top of this page pins the label git:20260908.12af43b, 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.
