+# LangGraph and LangChain Tool Security Scan
+
+Use this workflow for LangGraph or LangChain projects that expose tools to an
+agent loop.
+
+```bash
+agentshield scan . --ignore-tests --fail-on high --explain
+```
+
+AgentShield scans Python and TypeScript/JavaScript source, dependency metadata,
+tool schemas, file operations, network operations, and command execution
+surfaces that can affect a LangGraph or LangChain agent.
+
+For OpenAI and agent-tool guidance, see
+[OpenAI Agents security](../../docs/openai-agents-security.md).
