Optimize software performance through user-journey baselines, profiling, representative benchmarks, controlled experiments, and field verification. Use when asked to make an application, service, workflow, or hot path faster or more efficient, or to build the measurement loop first. Do not use for a reliability incident, capacity forecast, generic product A/B test, or operating a named telemetry or load-testing tool without an optimization objective.
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 optimization Improve a user-relevant outcome by repeatedly measuring, explaining, changing, and verifying one bottleneck at a time. A faster microbenchmark is a hypothesis about user benefit until the relevant end-to-end or field measure confirms it. Before the first mutation of a target system, confirm its target, scope, and rollback path from the user request or current project record. Read-only discovery needs no confirmation. For production telemetry, flags, deployment, or cleanup, follow the project's authority and review gates. ## When not to use Use [site-reliability-engineering](../site-reliability-engineering/SKILL.md) for SLO policy and incident recovery; [capacity-and-cost-engineering](../capacity-and-cost-engineering/SKILL.md) for demand and spend forecasts; [qa-methodology](../qa-methodology/SKILL.md) for general load/stress/soak test strategy; [product-experimentation](../product-experimentation/SKILL.md) for product behavior A/B tests; [systematic-debugging](../systematic-debugging/SKILL.md) for a specific functional failure. Operate a named observability stack with [telemetry](../telemetry/SKILL.md) or [grafana](../grafana/SKILL.md). ## The loop …

How to install
mdr add magnus919/agent-skills/performance-optimization@sha256:bad329c87e245021The line at the top of this page pins the label git:20260923.fc5805d, 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.
