performance-optimization
Optimizes application performance across frontend, backend, queries
by addyosmaniFree
Description
performance-optimization is an agent skill from Addy Osmani's agent-skills collection for improving application performance across the frontend, the backend, queries and databases. Its core rule is to measure before optimizing. Performance work without measurement is guessing, and guessing leads to premature optimization that adds complexity without improving what matters. The workflow is to profile first, identify the actual bottleneck, fix it, and measure again, optimizing only what the measurements prove matters. The skill applies when the spec has performance requirements such as load-time budgets or response-time SLAs, when users or monitoring report slow behavior, when Core Web Vitals scores fall below their thresholds, when a change is suspected of causing a regression, and when building features that handle large datasets or high traffic. It says not to optimize without evidence of a problem, since premature optimization costs more in complexity than it gains in speed.…

performance-optimization FAQ
What does the performance-optimization skill do?
It guides an agent to profile an application, find the real bottleneck, fix it and measure again, across the frontend, backend, queries and databases.
How do I install it?
Run: npx skills add https://github.com/addyosmani/agent-skills --skill performance-optimization
Should I optimize before a problem is measured?
No. The skill says to optimize only what measurements prove matters, because premature optimization adds complexity.
Which targets does it use?
It includes Core Web Vitals targets, and it applies to load-time budgets and response-time SLAs from a spec.
What security checks has it passed?
skills.sh lists three audits: Gen Agent Trust Hub Pass, Socket Pass and Snyk Pass.
What are the best performance-optimization alternatives?
Popular alternatives to performance-optimization include benchmark-optimization-loop, react-performance and agent-performance-optimizer. See all performance-optimization alternatives
