 ### Security and Code Execution
 
-- When using `allow_code_execution`, be cautious with user input and always validate it
-- Use `code_execution_mode: "safe"` (Docker) in production environments
-- Consider setting appropriate `max_execution_time` limits to prevent infinite loops

 # `CodeInterpreterTool`
 
+<Warning>
+  **Deprecated:** `CodeInterpreterTool` has been removed from `crewai-tools`. The `allow_code_execution` and `code_execution_mode` parameters on `Agent` are also deprecated. Use a dedicated sandbox service — [E2B](https://e2b.dev) or [Modal](https://modal.com) — for secure, isolated code execution.

 ## Description
 
 The `CodeInterpreterTool` enables CrewAI agents to execute Python 3 code that they generate autonomously. This functionality is particularly valuable as it allows agents to create code, execute it, obtain the results, and utilize that information to inform subsequent decisions and actions.

+### Path Validation
+
+File paths provided to this tool are validated against the current working directory. Paths that resolve outside the working directory are rejected with a `ValueError`.
+
+To allow paths outside the working directory (for example, in tests or trusted pipelines), set the environment variable:
+
+```shell
+CREWAI_TOOLS_ALLOW_UNSAFE_PATHS=true
+```
+
+### URL Validation
+
+URL inputs are validated: `file://` URIs and requests targeting private or reserved IP ranges are blocked to prevent server-side request forgery (SSRF) attacks.
