# Structured Debugging

For the bug that survived your first three fixes

## What this does

Some bugs do not give way to a quick look, and the first fix makes them stranger. This gives you a way to work: form a guess about what is happening, then test it, instead of poking around. Reach for it when behaviour seems impossible, when a test fails on and off, or when you are about to blame someone else's code.

### Top 3 things it does for you

- Work through a bug that makes no sense
- Track down a test that fails at random
- Follow a problem across systems that touch each other

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 Structured Debugging

A way of working through bugs that do not yield to a quick glance. Instead of trying fixes until one sticks, you form a hypothesis about what is happening and then investigate against it.

It is meant for the harder cases: unexpected behaviour, tests that fail intermittently, and problems that have to be traced through systems with many moving parts. It is especially for the moment after the first attempted fix did not work, or when what you are seeing seems impossible.

It also covers the temptation to blame something outside your control - a model, an API, a library - before you have evidence that the fault is there.

## Questions

### Is Structured Debugging safe to install?

AIR scanned this exact version of Structured Debugging and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 15342b89326d, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/structured-debugging.

### How do I install Structured Debugging?

Open https://airmarket.ai/app/structured-debugging 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/QwenLM/qwen-code/tree/15342b89326d293028a323f36a36ecc696a9d17b/.qwen/skills/structured-debugging. Install from that link, not the branch.
