dsh-session-archive-plugin

DSH ships with compaction-basic, which auto-compresses context once usage hits 80%, but the compressed logs remain as multi-frame zstd binaries—hard to read and impossible to search. When a key conclusion scrolls out of view, users are stuck flipping through raw binary logs. This plugin fills exactly that gap.

It exposes two model-callable tools: archive_session decodes the current session log into plain-text JSONL plus a Markdown summary saved under session_archives, with an idempotent guard that skips re-archiving when less than the configured threshold of new data has accumulated. search_archive first scans Markdown summaries across workspaces; if nothing matches it transparently decodes the most recent raw logs for a direct scan, supporting multi-word AND, limit, and deep parameters so history is always reachable. A bundled skill also nudges the model to proactively search archives after compression, closing the read-write loop.

Best for DSH users who run long, multi-turn reasoning sessions and need to retrieve specific inferences or decisions after compaction. If your workflow involves accumulating dense context and then hunting for a single detail, this plugin keeps every fact one search away, before or after compression.
