Investigate performance regressions and find opportunities for optimization
Install
With your agent
Install OMGSkills skill "sveltejs/svelte:performance-investigation" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/sveltejs/svelte /tmp/svelte && ln -s /tmp/svelte/.agents/skills/performance-investigation ~/.claude/skills/performance-investigationFrom README
Start from a branch you want to measure (for example foo). Run: If you pass one branch, bench:compare automatically compares it to main. Where outputs go Summary report: benchmarking/compare/.results/report.txt Raw benchmark numbers: benchmarking/compare/.results/main.json benchmarking/compare/.results/ .json CPU profiles (per benchmark, per branch): benchmarking/compare/.profiles/main/.cpuprofile benchmarking/compare/.profiles/main/.md benchmarking/compare/.profiles/ /.cpuprofile benchmarking/compare/.profiles/ /.md The .md files are generated summaries of the CPU profile and are usually the fastest way to inspect hotspots. Suggested investigation flow Open benchmarking/compare/.results/report.txt and identify largest regressions first.
