creo-perf-harness skillA

creo-perf-harness is agent-read markdown (skill) from oyusypenko/creo: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add oyusypenko/creo/creo-perf-harness@git:20260908.12af43b
Exact content
mdr add oyusypenko/creo/creo-perf-harness@sha256:dd151207b58c277d

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
