security-app-file-upload

The skill’s stated purpose and documented behaviors are largely coherent for a file-upload security review overlay, with no clear credential theft or exfiltration pattern in the skill text. The main issue is install/execution trust: it requires an `appsec-sdk` CLI whose provenance is not verified in the provided evidence, and the upstream trust chain points to mutable personal-GitHub ZIP distribution. Verdict: SUSPICIOUS due to high supply-chain risk, not confirmed malware.
