Lines 591-596 handle blank strings, but

This creates adapter contract drift and leaves an enabled Chat provider with a blank tool result.Check trimmed text before Line 599 when every content part is text. Add a regression case in

Addressed the maintainer review: ended the comment sentence in |
Blocker: the Responses emptiness check wipes real image and encrypted tool outputsThe Chat half of this PR is right, and the earlier CodeRabbit and maintainer items are genuinely closed at
return output.every(part => {
if (!isPlainObject(part)) return true;
if (typeof part.text === "string" && part.text.trim() !== "") return false;
if (part.type === "refusal" && typeof part.refusal === "string" && part.refusal.trim() !== "") return false;
return true; // <- input_image, encrypted_content, input_file all land here
});So an Your own Chat implementation gets this right and shows the intended rule: if (annotateEmpty && content.every(part => part.type === "text") && text.trim() === "") {That refuses to annotate a mixed array. Responses has no equivalent guard. This matters because the flag is on by default for DeepSeek (seeded in Why CI stayed greenThe Responses tests only cover To unblock
Two smaller notes
Leaving open rather than closing — the feature is worth having and the Chat side is already correct. |
