About
hipocampus is a plugin bundle for AI coding tools published by kevin-hs-sohn. Marketplaces we read that list it: 1 (Claude Code: claude-plugins-community). We first saw it on 2026-10-11 and have recorded no change since. As of our marketplace pass on 2026-10-12.
Persistent memory that survives across sessions. Hipocampus gives your agent a 3-tier memory system (hot/warm/cold) with a self-compressing 5-level compaction tree. Every session, the agent auto-loads a ~3K token topic index (ROOT.md) so it knows what it knows — then retrieves specific details on demand via tree traversal or hybrid search (BM25 + vector via qmd). All memory writes happen through subagents to keep your main session clean. Zero dependencies, zero infrastructure — just markdown files.

Is this your plugin?
Prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and can put its remote endpoint on monitoring as a web service.
Data comes from the public marketplace file https://github.com/anthropics/claude-plugins-community/blob/HEAD/.claude-plugin/marketplace.json. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
