Skill Sign
Security checks across malware telemetry and agentic risk
Overview
This is a local skill-signing utility that stores its own keypair and writes signature metadata, with no evidence of hidden network, exfiltration, or destructive behavior.
Install only if you want a local Ed25519 signing workflow for skills. Protect ~/.config/skill-sign/private.key, understand that --force replaces your signing identity, and use --trust-key or --trust-key-string from a trusted out-of-band source when verifying someone else’s skill.
