Questions, answered from the data.
What is the best security skill?
Security And Hardening from penpot/penpot ranks first of the 3,019 security skills listed here, with the highest score: its repository has 61k GitHub stars, 6 other GitHub owners carry a copy, its SKILL.md loads about 4.7k tokens and it has informational notes only in the automated safety check. Next come Security Auditor and Skill Inspector.
Which security skills are official?
168 of the 3,019 security skills are official, published by the vendor's own GitHub organization: Skill Inspector, ONNX Runtime Shape Inference Safety Audit, Deepsec Vulnerability Scanner, CodeQL Security Scan, Deepsec Documentation Guide and 163 more.
How are these skills ranked?
By Skill Navigator score, which combines the GitHub stars of the skill's repository (shared across that repo's skills and discounted for large collections), how many other GitHub owners carry a copy of the skill, and automated SKILL.md quality checks, minus penalties for safety-check warnings and for each further skill from the same repository. Skills that fail the safety check are not listed.
