You are writing authentication code. Default agent-written auth uses MD5 on passwords, stores JWTs in localStorage, generates session tokens with Math.random(), and lets reset links live for a week. Each of those is a documented breach pattern. This skill exists to fix them.
Forge Auth is a community-contributed Claude Code skill in the identity-access sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/forge-auth/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when designing or auditing auth - the highest-leverage place for security bugs to ship.
