Description

All copilot models do not have websearch and codesearch tools available. No matter the model I use, they all report those tools dont exist, only webfetch does. Howver using any of the same models from different providers show those tools existing. Issue with how tools are being sent to Copilot models?

Plugins

No response

OpenCode version

1.1.8

Steps to reproduce

  1. Activate copilot sub in opencode
  2. Ask what tools are available or just try and have any model execute websearch or codesearch. It cant.
