# Analyze Performance Profiles

See where the time goes when your code runs slow

## What this does

A function is taking longer than it should, or a page stutters, and all you have is a profiler file nobody wants to read by hand. Hand that file over: it reads V8 and Chrome CPU profiles and DevTools traces. It points you at the slow functions and the bottlenecks, so you know what to fix.

### Top 3 things it does for you

- Work out why a function is slow
- Compare code paths
- Track down the real bottleneck

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Analyze Performance Profiles

Performance problems leave evidence behind: a V8 or Chrome CPU profile saved as .cpuprofile, or a DevTools trace saved as Trace-*.json. This skill works through those files with you, digging out the slow functions and the bottlenecks recorded inside them.

It covers the questions that come up mid-investigation: why a particular function drags, whether one code path beats another, what a call tree from a sampling profiler is really saying, and how much time layout, paint and rendering take. User timing marks such as timeToRequest are part of the picture too.

## Questions

### Is Analyze Performance Profiles safe to install?

AIR scanned this exact version of Analyze Performance Profiles and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 530cb5de713a, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/cpu-profile-analysis.

### How do I install Analyze Performance Profiles?

Open https://airmarket.ai/app/cpu-profile-analysis on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/microsoft/vscode/tree/530cb5de713aec2e96059e2f6cf41a95403cdb3d/.github/skills/cpu-profile-analysis. Install from that link, not the branch.
