Enforce universal security protocols for safe, resilient software. Use when implementing authentication, encryption, authorization, input validation, secret management, or any security-sensitive feature across any language or framework.
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 Standards
## **Priority: P0 (CRITICAL)**
## Always-Apply Rules
Apply these on **every code write**, regardless of context:
- **No hardcoded secrets**: Use environment variables or secret managers. Never commit keys, passwords, or tokens to source control.
- **No raw SQL strings**: Use parameterized queries or ORMs — `WHERE id = ${userId}` always wrong.
- **No stacktraces in prod**: Return generic error codes; log full detail server-side only.
## Workflow
Activate when: implementing auth, encryption, authorization, input handling, or any security-sensitive feature.
1. **Identify trust boundaries** — map every data entry point (API, UI, CSV, webhook).
2. **Validate and sanitize** all external input at each boundary.
3. **Apply least privilege** to users, services, and containers.
4. **Verify** with SAST/DAST scanners in CI before merge.
## Context-Specific Rules
### Data Safeguarding
- **Zero Trust**: Never trust external input. Sanitize and validate every data boundary.
- **Least Privilege**: Grant minimum necessary permissions to users, services, and containers.
- **Encryption**: AES-256 for data-at-rest; TLS 1.3 for data-in-transit.

How to install
mdr add hoangnguyen0403/agent-skills-standard/common-security-standards@sha256:26ac1d160a2b2ffeThe line at the top of this page pins the label git:20261030.a5465a6, 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.
