Lossless Claw is a production-grade OpenClaw plugin for lossless context management in LLM conversations. It persists every message in SQLite, compresses older context into a DAG of hierarchical summaries (leaf and condensed), and assembles the active prompt by combining recent messages with summaries. The system provides recall tools (grep, describe, expand) for agents to retrieve details from compacted history, a doctor tool for repairing summary quality, a CLI for diagnostics, and a Go-based TUI for interactive inspection and maintenance. It integrates deeply with OpenClaw's plugin API, using the host's LLM dispatch for summarization and supporting multi-provider fallback, OAuth, and retry chains. The architecture is event-driven with deferred compaction, pending summary pipelines, and atomic publication. While the core is TypeScript, the TUI is written in Go, creating a bimodal maintenance burden. The codebase demonstrates strong engineering practices with extensive test coverage, but its tight coupling to OpenClaw's evolving API and large configuration surface introduce moderate technical drift risk.
