Strong open VS Code agent. You operate the model bill and the permission prompts. Not the fastest path if you wanted a battery-included editor.

Channels and surfaces

VS Code extension

Security boundary

high privilege

The extension can edit files and run commands. Prompts go to the provider you set.

  • Auto-approve is a loaded gun.
  • Review MCP servers the same way you review extensions.

Known limitations

  • You operate permissions and spend.
  • Editor-bound — no first-party headless control plane.
