System Documentation

What problem does it solve?

secret-warn provides real-time guardrails that detect secrets, sensitive patterns, and unsafe shell constructs the moment they appear in Claude Code tool-calls, preventing leaks before they land in drafts or CI.

Core Features & Use Cases

  • Real-time detection of API keys, private keys, and high-entropy strings in edit-time and shell commands.
  • PreToolUse and PostToolUse hooks plus a Bash guard to enforce safety across Claude Code workflows.
  • Maintains a base64-encoded registry of 11+ rules with allowlist and bypass options for controlled environments, plus an audit log for traceability.
  • Use case: during code review or drafting, it blocks or warns on secret exposures and unsafe commands, ensuring secure development sessions.
