Scan a source-code tree for hardcoded credentials embedded in source files: AWS access keys, GitHub tokens, Stripe keys, Slack tokens, Anthropic API keys, OpenAI keys, JWT signing secrets, generic base64-encoded passwords, RSA / SSH private keys, and high-entropy string literals that pattern-match common credential shapes. Use when: pre-commit gate before pushing a feature branch, audit before SOC2, post-incident scan after a leak, or inheriting a codebase you didn't write. Threshold: any source file contains a string that matches a canonical credential regex (AWS AKIA prefix, GitHub ghp_ prefix, etc.) OR a string with Shannon entropy above 4.5 in a field context (key=, token:, secret=). Trigger with: "scan secrets", "credential scan", "find hardcoded keys", "leak check".
