Quality-Max Secret Scan
Catch a leaked credential before it lands in git history. No signup required.
Prerequisites
- None. Pure Claude Code — works in any repo, no MCP required.
Trigger
- "Scan for hardcoded secrets"
- "Any leaked keys in my changes?"
- "Secret scan before I commit"
Workflow
- Choose scope:
- Pre-commit (default):
git diff+git diff --staged— only what's about to land. - Full tree: scan tracked files (skip
.git,node_modules, lockfiles,dist/, binaries).
- Pre-commit (default):
- Grep for these patterns (use
Grep/ripgrep). Report matches withfile:lineand the value masked (show first 4 chars only) — never echo a full live secret.
Patterns
| Provider / type | Signature |
|---|---|
| AWS access key | AKIA[0-9A-Z]{16} |
| AWS secret key | 40-char base64 near aws_secret |
| Google API key | AIza[0-9A-Za-z\-_]{35} |
| GitHub token | ghp_, gho_, ghs_, github_pat_ |
| Slack token | xox[baprs]- |
| Stripe | sk_live_, rk_live_ |
| OpenAI / Anthropic | sk-, sk-ant- |
| Private key block | `-----BEGIN (RSA |
| JWT | eyJ[A-Za-z0-9_-]+\.eyJ[A-Za-z0-9_-]+\. |
| Connection string | `(postgres |
| Generic assignment | `(password |
Triage each hit:
- Real secret → BLOCKER. Recommend: remove, rotate the credential, move to env/secret store.
- Placeholder / example (
your-key-here,xxxxx,${...}, obvious test fixture) → note as ignored. - In a committed file already in history → flag that rotation is needed regardless of removal.
Output:
## Secret Scan — git diff (staged + unstaged)
**2 real secrets, 1 placeholder ignored**
### BLOCKER
- `backend/config.py:14` — Stripe live key `sk_l…` hardcoded.
Rotate it now (it's compromised once committed) and load from env.
- `.env.example:9` — AWS key `AKIA…` looks real, not a sample.
Move to a non-tracked `.env` and rotate.
### Ignored (placeholders)
- `README.md:42` — `api_key = "your-key-here"` — example text.
