Annotrace: A tool for step-level annotation of AI agent traces
In brief
- Annotrace structures AI agent traces into nested, ordered steps for detailed analysis.
- The tool combines human annotation with frontier model suggestions to speed up the process.
- It measures agreement between annotators, human or AI, with a kappa score of 0.82.
Annotrace is an open-source tool designed to annotate AI agent execution traces at the granularity of individual steps. It enables human-AI collaboration to build structured datasets and assess annotation consistency between humans and models.
