dsh-plugin-om

Long-running DSH sessions fill the context window quickly, and naive truncation throws away information you still need. dsh-plugin-om adopts an Observational Memory strategy: before each agent step it automatically compresses earlier messages into summary blocks, and once those blocks exceed a second threshold they are merged into a single tighter digest, reducing token pressure while preserving semantic content.

Beyond auto-compression, the plugin ships two recall tools: recall retrieves original messages by index range including image attachments, and recall-semantic runs a local embedding model to perform semantic search across all full messages so content buried inside summaries can still be surfaced. Abstract parsing uses a tag-anchored extraction pipeline with a fuzzy-rebuild fallback, and when core services misbehave the compressor degrades gracefully, reporting a single warning event rendered as an expandable row in the browser client without blocking the session.

If you rely on DSH for multi-turn agent workflows or long-chain reasoning and want tighter context management than the built-in compaction-basic while keeping the ability to trace back to original messages at any time, this plugin is a strong fit. Even with auto-compression disabled, the recall and recall-semantic tools remain fully functional, making it suitable for everything from solo long sessions to multi-agent coordination pipelines.
