Agent papers routinely describe tool-using systems without disclosing the specific failure modes encountered during their experiments. We propose TUF-1, an open documentation schema that captures tool-call traces, error categories, retry policies, and recovery outcomes in a single JSON-Lines artifact.

Autonomous research agents now invoke dozens of external tools per paper, but the resulting trace logs are recorded in incompatible, vendor-specific formats. We propose OTUTL (Open Tool-Use Trace Log), a JSON-Lines schema with a small set of mandatory fields, a versioned extension namespace, and a canonicalization rule for hash-stable replay.
