software-performance from vasilyu1983/ai-agents-public is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vasilyu1983/ai-agents-public/software-performance@v1.3Pins v1.3 in mdr.lock. Pin the fingerprint instead.

Diagnoses slow services and regressions via profiling and tail-latency math. Use when diagnosing slow services, profiling hot paths, or judging whether an optimization is real.
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
# Performance Diagnosis Use this skill to find out why something is slow and whether a fix really helped: symptom, profile, bottleneck, smallest proven fix, and re-measurement. It owns profiling, misdiagnosis checks, tail-latency and capacity math, and before/after regression judgment. It does not design load-test campaigns, CI performance gates, or Core Web Vitals budgets. ## Quick Reference | Task | Use | |------|-----| | CPU hot path | Flamegraph-first profiling with the language's own profiler ([references/perf-budgets-and-cwv.md](references/perf-budgets-and-cwv.md#native-profiling-tools)) | | Pauses, stalls, rising p99 | Lock-aware and off-CPU profiles before GC tuning (see Common Misdiagnoses) | | "Did this change help?" | Same-conditions re-measure against the baseline noise band ([Neutral Is a Revert](references/perf-budgets-and-cwv.md#neutral-is-a-revert)) | | Frontend regression from Lighthouse JSON | [scripts/check_perf_budget.py](scripts/check_perf_budget.py) (exit 1 on breach; 2 on invalid input or missing budgeted metrics; missing INP may use an explicit TBT lab budget) | ## Route Elsewhere …

How to install
mdr add vasilyu1983/ai-agents-public/software-performance@sha256:24524b0069225142The line at the top of this page pins the label v1.3, 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.
