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: use the OMGSkills MCP get_skill tool, install only the pinned_install commit and path, verify SKILL.md against pinned_install.skill_md_sha, 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.
