Secret Detection

What This Does

This skill provides a git pre‑commit hook that scans staged files for common secret patterns (API keys, passwords, tokens) and blocks the commit if any are found. It helps prevent accidental leakage of secrets to public repositories.

Inputs: Git staged files (automatically scanned by the hook) or manual file paths.
Outputs: Detection report with line numbers; non‑zero exit code if secrets found.

When To Use

Use this skill when:

• - You work with repositories that may contain sensitive credentials
• You want to prevent accidental commits of secrets
• You need a lightweight, local secret scanner for git workflows
• You want to enforce security checks before pushing to remote

Usage

Installation

Manual Scan

Hook Behavior

• - The hook runs automatically on INLINECODE0
• If secrets are detected, the commit is blocked
• The script prints the detected secrets with file names and line numbers
• Exit code 0 = no secrets found; exit code 1 = secrets found

Examples

Example 1: Installing the Hook

Example 2: Secret Detection Blocking a Commit

Example 3: Manual Scan

Requirements

• - Git (for hook installation)
• Python 3.6+ (for the scanner)
• No external API keys or services needed

Limitations

• - Only detects common secret patterns (AWS keys, GitHub tokens, passwords, etc.)
• May produce false positives (e.g., long random strings that aren't actually secrets)
• Does not scan binary files
• Requires manual installation per repository
• Does not replace comprehensive secret‑management solutions
• Prints first 20 characters of detected secrets to console for identification purposes
