# Test Confidence

Let the model choose which tests your change actually needs

## What this does

You have made a change and you are not sure which tests are worth running for it. This looks at your diff, decides what to run, and says how much confidence the result deserves. You do not pick the test selection yourself.

### Top 3 things it does for you

- Run the tests that match what you changed
- Get a read on how much the result should be trusted

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 Test Confidence safe to install?

AIR scanned this exact version of Test Confidence and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 2a46b7980d9c, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/test-confidence.

### How do I install Test Confidence?

Open https://airmarket.ai/app/test-confidence 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/antiwork/gumroad/tree/2a46b7980d9c3c20b0b015ff216014c0b6e83ac7/.agents/skills/test-confidence. Install from that link, not the branch.
