Who it is for
Teams running long-lived OpenClaw conversations that need to recover details from earlier work.
The problem
Model context windows are finite. Truncating old messages can remove facts that an agent needs later in the same project.
How it works
Lossless Claw stores raw messages in SQLite, summarizes older chunks into a hierarchy, and assembles recent messages with relevant summaries. Recall tools let an agent search and expand the original detail.
Martian Engineering's role
Martian Engineering builds and publishes Lossless Claw as an OpenClaw plugin.
Public evidence
The public repository had more than 4,800 GitHub stars when checked on September 20, 2026. Its README documents persistence, summarization, and recall behavior.
