参数错误：generatedFiles 不能为空

Error message

参数错误：generatedFiles 不能为空

What it means

After successfully unmarshalling 'generatedFiles' into a []string, Handle rejects an empty array with this error. The reviewer needs at least one file path to build the adjustment prompt; an empty list would produce a meaningless review, so it is treated as invalid input.

Solutions

1. Populate the array with at least one valid file path before calling the tool.
2. Fix the upstream file-collection logic so it actually gathers generated files (log the list before sending).
3. If nothing was generated, skip the review call instead of invoking it with an empty list.
4. Validate on the client: marshal the list, check len > 0, then call.

Example fix

// before
if err := json.Unmarshal(b, &files); err != nil { return err }
callReview(req, files) // files may be empty
// after
if err := json.Unmarshal(b, &files); err != nil { return err }
if len(files) == 0 { return errors.New("no generated files to review") }
callReview(req, files)

var files []string
_ = json.Unmarshal([]byte(generatedFilesStr), &files)
if len(files) == 0 {
    return errors.New("refusing to call gva_review with an empty generatedFiles list")
}

When it happens

Trigger: Calling gva_review with 'generatedFiles' set to "[]" or a JSON string that unmarshals to a zero-length slice.

Common situations: File-collection step upstream produced no results (glob matched nothing, all files filtered out); caller passes a placeholder empty array to satisfy the presence check from error 32; logic bug where files were added to the wrong variable.
