Letta releases a trajectory parser that shrinks agent logs by about 5×
_ScottCondron · x · 2026-07-25
Letta AI says it has released a library and npm package for converting harness-agnostic agent trajectories into a canonical, token-efficient format.
- The team says the format is about 5× smaller than raw JSONL for agent consumption.
- It is already used in production inside the Letta Code harness as the preprocessor for dreaming cycles.
- The goal is to make fine-tuning, memory, and judge runs on trajectories more efficient and consistent across different sources.
The post frames trajectory parsing as a missing layer in agent workflows: instead of handling many source-specific formats, the tool normalizes them into something agents can ingest directly.
