What Hipocampus Search does

Hipocampus Search looks up memory with qmd using BM25 and optional vector search, then follows the compaction tree when needed. Use ROOT.md first to decide whether to search memory or look externally.

Hipocampus Search is cataloged under AI Engineering on DirSkills. Hipocampus Search comes from a repository tagged agent-memory, ai-agent, ai-memory, claude-code and compaction-tree.

Excerpt

Hipocampus Search

Quick Reference

Action	Command
Hybrid search (best quality)	`qmd query "keyword1 keyword2"`
Keyword search (fast)	`qmd search "keyword1 keyword2"`
