Regardless of the prompt, I was getting these errors constantly, with opencode asking for a required "description" parameter.

{"message":"tool call validation failed: parameters for tool bash did
not match schema: errors: [missing properties: 'description',
additionalProperties 'description=' not
allowed]","type":"invalid_request_error"}

Making the parameter optional and completely fixed the issue
here is the PR: https://github.com/sst/opencode/pull/1333
