# Fact Checking

Test the claims before anyone else finds the wrong one

## What this does

Writing that sounds right can still be wrong, and the wrong part is usually found by whoever reads it next. This reviews claims by trying to argue against them, and checks references and API endpoints. Reach for it before something technical goes out the door.

### Top 3 things it does for you

- Check whether a claim actually holds up
- Verify the references in a piece of writing
- Confirm an API endpoint is what it says it is

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 Fact Checking

This reviews and validates claims using counter-hypothesis testing, meaning claims are checked by testing against them rather than looking for agreement.

It applies to verifying technical content, checking references, and validating API endpoints, as well as a general quality assurance pass over a deliverable before it is finished.

## Questions

### Is Fact Checking safe to install?

AIR scanned this exact version of Fact Checking and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 28962e2e56a4, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/fact-checking.

### How do I install Fact Checking?

Open https://airmarket.ai/app/fact-checking 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/bradygaster/squad/tree/28962e2e56a4206581645effa868ee2743ae39c7/packages/squad-cli/templates/skills/fact-checking. Install from that link, not the branch.
