performance:benchmark SKILL.md skillA
performance:benchmark from bendrucker/claude is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add bendrucker/claude/performance:benchmark@git:20261030.aa1b6afPins git:20261030.aa1b6af in mdr.lock. Pin the fingerprint instead.

Use when timing a program or command, asking whether a change or version made it faster, or building a benchmark harness. To hill-climb or repeatedly optimize toward a target, use performance:hill-climb.
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
# Benchmark Goal: a comparison the user can trust. Every arm runs the same scenario from the same starting state, the arms are interleaved so machine drift hits them equally, the noise floor is measured before any difference is read, and a difference counts only when it clears that floor. ## Tools - `hyperfine` 2.0 or later: !`hyperfine --version 2>/dev/null || echo "not found. Required unless the project's own tooling covers its job."` - `bun` (runs `compare.ts`): !`bun --version 2>/dev/null || echo "not found. Required for compare.ts."` ## Existing Tooling Look for the project's own benchmarks before building one: package scripts, a `bench/` directory, benchmark tests, CI jobs that time something. Check each against the requirements the setup below is built to meet: - **Scenario.** It runs the scenario the user cares about, from the same starting state every run. - **Isolation.** Network, remote state, and caches are stubbed, held fixed, or reset per run. - **Interleaving.** Arms alternate within one run or one process, so drift hits every arm. - **Samples.** It keeps every run's measurement, enough of them to show an A/A noise floor, not only a mean. …

How to install
mdr add bendrucker/claude/performance:benchmark@sha256:f54a9912811b2e8dThe line at the top of this page pins the label git:20261030.aa1b6af, 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.
