Perf Measurement includes explicit scope boundaries (an explicit 'when not to use' or 'out of scope' section); pricing or quota commentary. At roughly 1,790 words the SKILL.md is on the longer end of the catalog distribution.
Perf Measurement sits in the Dev Tools category under the package-mgmt sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.
These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.
Use this skill to make server/hot-path performance work empirical instead of speculative: pick a metric that survives noise, isolate the cost with controls and profiling, attribute it to the right layer, change one thing, and re-measure. The recurring failure mode this skill prevents is plausible-but-wrong optimization — a change that "should" help (smaller capture, faster allocator, fewer copies) but moves nothing, or a change credited by a contaminated benchmark.
Perf Measurement is a community-contributed Claude Code skill in the package-mgmt sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/perf-measurement/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when: optimizing or investigating the throughput, latency, or per-request cost of a C++ network server (or similar hot-path service); deciding whether a change actually helped; choosing a metric that resists noise; isolating where time/allocations go with profiling and controls; or avoiding common measurement mistakes (noisy benchmarks, contaminated runs, blaming the wrong layer, custom-allocator cargo-culting).
The Perf Measurement Claude Code skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
