Implement virtual tools feature to allow GitHub Copilot models to run with more than 128 tools #2513
Closed as not planned
Description
Currently, GitHub Copilot models are restricted to a maximum of 128 tools configured. If you have more than 128 tools configured in OpenCode, then the API calls fail. To overcome this limitation, the VSCode team implemented a virtual tool concept that automatically activates them on demand. This is a proposal to implement something similar in OpenCode so that configuring more than 128 tools in OpenCode with GitHub Copilot does not fail with an API call.

Facing this issue as well:
#4909
Is there a fix planned or a work around available?
EDIT: check this: #4909 (comment)

This isn't a super high priority for us currently but we will prolly have something for that eventually.
I suppose for the time being we can implement some warning or error toast specifically for copilot

This feature will really help if you can add a virtual tool for copilot!!
