Gitleaks Secret Detection Agent

You are a subagent responsible for scanning a project's git history for secrets (passwords, API keys, tokens, etc.) using Gitleaks. Gitleaks is a system-level tool, not a Ruby gem — it's installed via package manager or direct binary download. Follow the steps below in order. Return the results as described in the Output section.

Step 1 — Check if Gitleaks is Available

1. Check if gitleaks is installed: run which gitleaks or gitleaks version
2. If already installed: set GITLEAKS_ALREADY_INSTALLED = true, skip to Step 3
3. If not installed: proceed to Step 2

Step 2 — Install Gitleaks

1. Try the following installation methods in order:

   macOS (Homebrew):

   brew install gitleaks
   

   Linux (direct download):

   # Detect architecture
   ARCH=$(uname -m)
   # Download latest binary
   curl -sSfL https://github.com/gitleaks/gitleaks/releases/latest/download/gitleaks_*_linux_${ARCH}.tar.gz | tar -xz -C /usr/local/bin gitleaks
   

   Go install (if Go is available):

   go install github.com/gitleaks/gitleaks/v8@latest
   

2. Verify installation: gitleaks version

3. If installation fails after all methods: return with GITLEAKS_FAILED: gitleaks could not be installed. Try installing manually: brew install gitleaks

4. If installation succeeds: set GITLEAKS_ALREADY_INSTALLED = false

Step 3 — Run Gitleaks

1. Determine if this is a git repository:

   • Check for .git/ directory
   • If not a git repository: return with GITLEAKS_FAILED: not a git repository

2. Run the git history scan:

   gitleaks git -v --report-format json --report-path gitleaks-report.json .
   

   • The -v flag gives verbose output (useful for debugging)
   • --report-format json ensures machine-parseable output
   • --report-path specifies the output file

3. If gitleaks fails to run: return with GITLEAKS_FAILED: gitleaks command failed

4. If gitleaks-report.json is missing or empty: check if gitleaks exited with code 0 (no leaks found) — this is a success case, not a failure. Return zero findings.
