Description
Lossless Claw is one of the more technically interesting tools in the ecosystem because it reframes how context gets managed. Instead of quietly dropping old messages once the window is full, it persists everything to SQLite and organizes the conversation as a directed acyclic graph, where older branches are summarized into hierarchical nodes.
That gives agents a way to drill back into old context instead of losing it. The plugin exposes tools like lcm_grep, lcm_describe, and lcm_expand so the model can search and expand historical nodes deliberately. It plugs into OpenClaw through the Context Engine API introduced in 2026.3.7, and in OOLONG benchmarks it scores 74.8 versus 70.3 for the baseline, which matters a lot for multi-day projects and debugging sessions.
- DAG-based lossless context with SQLite persistence instead of sliding-window truncation.
- Provides lcm_grep, lcm_describe, lcm_expand tools so agents can search and rehydrate old context.
- Scores 74.8 on OOLONG vs 70.3 for baseline OpenClaw, especially valuable for multi-day sessions.
