Individual skill
secure-code-guardian
Use when implementing authentication/authorization, securing user input, or preventing OWASP Top 10 vulnerabilities — including custom security implementations such as hashing passwords with bcrypt/argon2, sanitizing SQL queries with parameterized statements, configuring CORS/CSP headers, validating input with Zod, and setting up JWT tokens. Invoke for authentication, authorization, input validation, encryption, OWASP Top 10 prevention, secure session management, and security hardening. For pre-built OAuth/SSO integrations or standalone security audits, consider a more specialized skill.

# Secure Code Guardian
## Core Workflow
1. **Threat model** — Identify attack surface and threats
2. **Design** — Plan security controls
3. **Implement** — Write secure code with defense in depth; see code examples below
4. **Validate** — Test security controls with explicit checkpoints (see below)
5. **Document** — Record security decisions
### Validation Checkpoints
After each implementation step, verify:
