auth-identity — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited auth-identity (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

This skill outlines the strict security requirements and architectural patterns for implementing Authentication and Identity (AuthN/AuthZ) in modern applications.
CRITICAL HITL GATE: You MUST stop and ask the user for explicit confirmation before modifying authentication flows, updating token expiration times, changing cookie settings (httpOnly,Secure), or adding new OAuth providers. Auth changes carry high risk of introducing vulnerabilities. Never silently commit auth logic.
