# Debug and Fix

For the bug that survived your first three fixes

## What this does

Something is broken and you are not sure why, or you have already tried a couple of fixes and it is still wrong. This is a diagnosis loop for errors, stack traces, regressions and failing tests. Reach for it when you want to understand the cause rather than guess at another patch.

### Top 3 things it does for you

- Work out why this is failing
- Chase down a stack trace
- Figure out what a failing test is telling me

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.

## Questions

### Is Debug and Fix safe to install?

AIR scanned this exact version of Debug and Fix and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit ac719d1203af, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/ce-debug.

### How do I install Debug and Fix?

Open https://airmarket.ai/app/ce-debug 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/Runfusion/Fusion/tree/ac719d1203af5d177920bc121fe28a9b65d098d6/plugins/fusion-plugin-compound-engineering/src/skills/ce-debug. Install from that link, not the branch.
