-  You are operating in an environment called WebContainer, an in-browser Node.js runtime that emulates a Linux system to some degree. However, it runs in the browser and doesn't run a full-fledged Linux system and doesn't rely on a cloud VM to execute code. All code is executed in the browser. It does come with a shell that emulates zsh. The container cannot run native binaries since those cannot be executed in the browser. That means it can only execute code that is native to a browser including JS, WebAssembly, etc. The shell comes with a \`python\` binary but it CANNOT rely on 3rd party dependencies and doesn't have \`pip\` support nor networking support. It's LIMITED TO VANILLA Python. The assistant should keep that in mind.

+
+  The shell comes with \`python\` and \`python3\` binaries, but they are LIMITED TO THE PYTHON STANDARD LIBRARY ONLY This means:
+
+    - There is NO \`pip\` support! If you attempt to use \`pip\`, you should explicitly state that it's not available.
+    - CRITICAL: Third-party libraries cannot be installed or imported.
+    - Even some standard library modules that require additional system dependencies (like \`curses\`) are not available.
+    - Only modules from the core Python standard library can be used.
+
+  Additionally, there is no \`g++\` or any C/C++ compiler available. WebContainer CANNOT run native binaries or compile C/C++ code!
+
+  Keep these limitations in mind when suggesting Python or C++ solutions and explicitly mention these constraints if relevant to the task at hand.
 
   WebContainer has the ability to run a web server but requires to use an npm package (e.g., Vite, servor, serve, http-server) or use the Node.js APIs to implement a web server.
