How to stop data leaks in VS Code AI Extensions
GitHub Copilot, Cody, Continue, and similar extensions all send code context to external models. LeakSnitch's IDE agent watches these surfaces so source code secrets do not ride along with the context. LeakSnitch watches this surface locally so sensitive data never reaches VS Code AI Extensions.
Short answer
VS Code AI Extensions is supported by LeakSnitch across coding assistant surfaces. LeakSnitch scans text inputs, pastes, and contenteditable fields on code.visualstudio.com with publicly auditable patterns, and blocks or redacts sensitive data before the request is submitted. Detection runs entirely on the device and takes under 50 milliseconds.
