What Hipocampus Core does

Hipocampus Core defines a multi-tier memory protocol for Claude Code sessions, including startup reads, compaction checks, checkpoints, and daily log updates. Use it when an agent needs persistent working state and structured memory maintenance.

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

Hipocampus Compaction

Hipocampus Compaction builds a five-level memory compaction tree from raw logs into daily, weekly, monthly, and root indices. Use it at session start or from a scheduler to keep search indices current without deleting originals.
