Short description

error: could not determine executable to run for package @cortexkit/aft-opencode

What happened?

Expected:

Successfully edit text using AFT's edit tool.

Observed issues:

grok 4.5 is unable to successfully edit files using AFT's edit.
It seems impossible to pass both the oldString and newString parameters at the same time.
Tried various methods.
Had the model first outline the call parameters, reflect on them, and then make the call. -> Failed
Had GLM successfully make the call once within the context, then switched to grok 4.5 and had grok make the call. -> Failed

After uninstalling the AFT plugin, grok successfully calls edit to modify the text without errors.

Reproduction

After installing the AFT plugin in opencode, use Build mode to have grok 4.5 modify a line in the md file to new content.
