## Questions

### Is Face Swap (HeyGen API) safe to install?

AIR scanned this exact version of Face Swap (HeyGen API) and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit fdd6457fed4d, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/faceswap.

### How do I install Face Swap (HeyGen API)?

Open https://airmarket.ai/app/faceswap 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/calesthio/OpenMontage/tree/fdd6457fed4d00aef47e40cc0a7635e6d37d5729/.agents/skills/faceswap. Install from that link, not the branch. It needs \[object Object\] to be reachable before it can do anything.
