No Hardcoded Credentials.

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

rule_id: codeguard-1-hardcoded-credentials

# No Hardcoded Credentials

NEVER store secrets, passwords, API keys, tokens or any other credentials directly in source code.

Treat your codebase as public and untrusted. Any credential that appears in source code is compromised and must be handled through secure alternatives.

#### NEVER hardcode these types of values:

Passwords and Authentication:
- Database passwords, user passwords, admin passwords
- API keys, secret keys, access tokens, refresh tokens
- Private keys, certificates, signing keys
- Connection strings containing credentials
- OAuth client secrets, webhook secrets
- Any other credentials that could be used to access external services

#### Recognition Patterns - Learn to Spot These Formats

Common Secret Formats You Must NEVER Hardcode:

- AWS Keys: Start with `AKIA`, `AGPA`, `AIDA`, `AROA`, `AIPA`, `ANPA`, `ANVA`, `ASIA`
- Stripe Keys: Start with `sk_live_`, `pk_live_`, `sk_test_`, `pk_test_`
- Google API: Start with `AIza` followed by 35 characters
- GitHub Tokens: Start with `ghp_`, `gho_`, `ghu_`, `ghs_`, `ghr_`
- JWT Tokens: Three base64 sections separated by dots, starts with `eyJ`

How to install

The exact contents, by fingerprint
mdr add cisco-ai-defense/skill-scanner/.cursor/rules/codeguard-1-hardcoded-credentials.mdc@sha256:e05e14353c403280

The line at the top of this page pins the label v1.0.1, 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.
