secret-detection SKILL.md skillF

secret-detection from hermeticormus/libresecops-claude-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add hermeticormus/libresecops-claude-code/secret-detection@git:20260930.71a2663

Pins git:20260930.71a2663 in mdr.lock. Pin the fingerprint instead.

Secret detection reference: pattern, entropy, and verification approaches, formats of common credentials, gitleaks and trufflehog configuration, and false positive management. Use when setting up secret scanning or tuning its rules.

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

# Secret Detection

> Detection patterns, tool configuration, regex patterns for common secret types, and false positive management for secret scanning.

## Knowledge Base

### Detection Approaches

**Pattern-based detection** matches known credential formats using regular expressions. This is the most reliable approach with the lowest false positive rate, but it only catches secrets with known formats.

**Entropy-based detection** identifies strings with unusually high Shannon entropy (randomness). Catches secrets without known formats but produces more false positives on minified code, UUIDs, and encoded data.

**Verification-based detection** takes a detected pattern and attempts to validate it against the issuing service's API. This eliminates false positives completely but requires network access and may trigger rate limits or security alerts.

**Contextual detection** examines variable names, configuration keys, and surrounding code to identify secrets. A random-looking string assigned to `AWS_SECRET_ACCESS_KEY` is more likely a secret than the same string in a UUID field.

How to install

The exact contents, by fingerprint
mdr add hermeticormus/libresecops-claude-code/secret-detection@sha256:d274d7d0f4f2f9f6

The line at the top of this page pins the label git:20260930.71a2663, 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.

Starting a new one? Use a template for SKILL.md on mdpantry, which passes every one of these checks and says what to change in it.
