Credential Leak Detector

Category: Security  ·  Sub-category: security-misc  ·  Last updated:

PostToolUse hook that scans Bash tool output for leaked credentials — API keys, tokens, private keys, and secrets — before they reach the conversation. Blocks critical leaks, redacts high-severity matches, and warns on suspicious patterns. 14 detection patterns covering OpenAI, Anthropic, AWS, GitHub, Stripe, Google, Slack, SendGrid, Twilio, PEM keys, bearer tokens, and generic secrets. No external dependencies. Trigger words: security, credential leak, secret exposure, key detection, token scan, API key leaked, credential guard, secret scanner, prevent credential leak.

From the source SKILL.md

Every time your agent runs a Bash command, the output flows back into the conversation — and into your API provider's logs, any monitoring tools, and the model's context window. If that output contains an API key, a private key, or a database password, the credential is now exposed in places you never intended.

Credential Leak Detector is a community-contributed Claude Code skill in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/credential-leak-detector/ and loads when your prompt matches the skill's trigger.
