sgl-project/sglang#43273 · upstream bug reproduced by running the issue's own reproduction
✓ Badgr rejects this response
Streamed arguments came out as '{"a": 1, 2}' (and '{"b": True}'), which no JSON parser accepts.
Outcome contract verdict: tool call arguments are not complete JSON. The attempt is recorded as failed (invalid_outcome) instead of a verified success, so it is not billed as a good answer and can fall back to another route.
The output the bug produces, taken from the issue’s reproduction and fed to Badgr’s validators. Not a live provider call.
