Description

Frozen — cross-agent persistent memory for coding assistants. Still works; the compressed-memory core now ships inside JuliusBrussee/caveman.

**Status: frozen (August 2026).** cavemem is no longer in active development. Everything below still installs and works, but expect no new features or fixes. Its compressed-memory core lives on inside [caveman](https://github.com/JuliusBrussee/caveman) — the actively developed home of the family, alongside [caveman-browse](https://github.com/JuliusBrussee/caveman-browse).

Cross-agent persistent memory for coding assistants. Hooks fire at session boundaries, compress observations with the caveman grammar (~75% fewer prose tokens, code and paths preserved byte-for-byte), and write to local SQLite. Agents query their own history through three MCP tools. No network. No cloud.

**Supports:** Claude Code · OpenCode · Codex · GitHub Copilot · Augment Code · Cursor (query-only) · Gemini CLI (query-only) · Antigravity (query-only) · IBM Bob (query-only)

Persistent memory across sessions. Hooks capture what happened; the store keeps it.
Compressed at rest. Deterministic caveman grammar, round-trip-guaranteed expansion for humans.
Progressive MCP retrieval. search, timeline, get_observations — agents filter before fetching.
Hybrid search. SQLite FTS5 keyword + local vector index, combi
