Zero infrastructure — just files. One command to set up. Works immediately with Claude Code, OpenCode, and OpenClaw. Benchmark Evaluated on MemAware — 900 implicit context questions across 3 months of conversation history. The agent must proactively surface relevant past context that the user never explicitly asks about. Method Easy (n=300) Medium (n=300) Hard (n=300) Overall -------- :---: :---: :---: :---: No Memory 1.0% 0.7% 0.7% 0.8% BM25 Search 4.7% 1.7% 2.0% 2.8% BM25 + Vector Search 6.0% 3.7% 0.7% 3.4% Hipocampus (tree only) 14.7% 5.7% 7.3% 9.2% Hipocampus + BM25 18.7% 10.0% 5.7% 11.4% Hipocampus + Vector 26.0% 18.0% 8.0% 17.3% Hipocampus + Vector (10K ROOT) 34.0% 21.0% 8.0% 21.0% Hipocampus + Vector is 21.6x better than no memory and 5.1x better than search alone . On hard questions (cross-domain, zero keyword overlap), Hipocampus scores 8.0% vs 0.7% for vector search — 11.4x better . Search structurally cannot find these connections; the compaction tree can. Increasing the ROOT.md budget from 3K to 10K tokens (120 topics vs 39) improves Easy from 26% to 34% and overall from 17.3% to 21.0% — more topic coverage means more connections found. Hard tier remains at 8.0%, indicating cross-domain reasoning is bottlenecked by the answer model, not the index size. Install Claude Code Plugin Then run npx hipocampus init for full setup.
