AgentTrace: black-box model attribution from tool-call repair trajectories
Claim-level citations (2)
- supportsAgentTrace fingerprints model identity from malformed tool-call repair paths: AgentTrace uses the time-ordered sequence of failed tool calls and repair attempts, modeled with lightweight Markov chains, to distinguish evaluated models that share a tokenizer, including Llama-3 8B and 70B variants.
Abstract, repair sequences and intra-family variants
- supportsAgentTrace fingerprints model identity from malformed tool-call repair paths: The paper studies black-box attribution using deliberately malformed tool schemas and the sequence of model attempts to repair them, reporting 96 percent attribution in a selected identity-spoofing test configuration.
Abstract; malformed schema challenge and Markov repair trajectory evaluation
