Skill Sign

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local signing and verification tool for skills, with no evidence of hidden network access, exfiltration, or unsafe automatic behavior.

Install only if you want a local skill-signing workflow. Protect ~/.config/skill-sign/private.key, use --force only when intentionally replacing your signing identity, and verify other authors with a public key obtained from a trusted out-of-band source.
