Trajectory SDK

Trajectory SDK converts raw agent traces from observability platforms like LangSmith into a clean, standardized Trajectory format — ready for fine-tuning, evaluation, and analysis.

Key Features

  • Provider-pluggable — LangSmith today, extensible to any trace source
  • Standardized schema — typed dataclasses for messages, tool calls, rewards, and metrics
  • Bulk import — process thousands of conversations from Parquet exports
  • PII redaction — pluggable redaction before data leaves your environment

All processing runs locally. Your API key and data never leave your environment.
