Weir

Open-source (Apache-2.0) API key leak detection for AI agents: plants fake keys where real ones live, runs your agent's flows and reports whether they reached traces, logs, console output, the model or other services (leak, clean or incomplete), and in Claude Code shows which of your real keys entered or left a session, with an optional hook that redacts them. pip install weir-scan.
