Security hardening and vulnerability defense skill. Enforces OWASP Top 10 mitigations, zero hardcoded secrets, input sanitization, and SQL parameterization.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Security Hardening & Vulnerability Defense (`/security`)
> **Philosophy**: *Assume breach. Defense in depth. Never trust client input. Never interpolate variables into queries or shell commands. Never commit credentials. Hash passwords with Argon2id.*
This skill establishes defensive security standards across web applications, APIs, databases, container environments, and secret management lifecycles.

## 2. OWASP Top 10 Hardening Standards
### 2.1 Injection Prevention (SQL, Command, LDAP)
- **Zero SQL String Interpolation**:
```typescript
// ❌ VULNERABLE: Direct SQL injection risk
const user = await db.query(`SELECT * FROM users WHERE email = '${email}'`);
// ✅ DEFENSIVE: Parameterized prepared statement

How to install
mdr add darknecrocities/skillbuilder/security@sha256:2e87ca2e47bd1c36The line at the top of this page pins the label git:20261025.ada6d1d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
