Memoose

A dual-path memory system for proactive agents. Pick up where you left off, in whichever agent you open tomorrow.

pip install memoose
memoose install claude             # or: codex | opencode | cursor

You explained the architecture, the conventions, and the reason behind last week's decision. Memoose is how your agent still knows them today. It is a harness: a deterministic store reached through MCP tools or the command line, plus skills that teach the model you are already running how to use it.

What a memory harness is

Memoose splits memory in two, and the split is the whole design.

Everything deterministic lives in the library: a typed graph store, an ontology, chunking, ranking, supersession, a provenance ledger. It is a plain MCP server over one SQLite file, and it has no opinions. It validates, stores, ranks and refuses bad input.

Everything that needs judgment is written down as a skill: what counts as an entity, which facts conflict, what is worth remembering, what a session taught. That thinking is done by the host's model, the one you are already running, while it calls the tools. So Memoose ships no model of its own and needs no API key.

Your memory is a typed knowledge graph that stays on your machine. Recalled facts become context for your host's model, the same as anything else it reads.

SurfaceWhat it doesNeeds
MCP toolsThe deterministic store: typed graph, ontology, ranking, supersession, provenanceAny MCP host
SkillsTeach the host model to extract, judge, and route memory work to a small-model subagentAny host with skills
HooksCapture and recall without being asked: hints before each prompt, standing context at session start, capture when a turn ends and before compactionHosts that run plugin hooks

The core is portable: skills plus an MCP server, on any host that speaks MCP. The capture and recall that happen without you asking sit on top of that core and depend on what your host supports. They add no capability the tools do not already have, so where they are unavailable you keep everything through the tools, the skills and the delegated subagent.

What it is built for

Long-lived project work: the decisions, conventions and ownership facts that have to stay true for months. That makes the interesting questions less about finding a fact once and more about whether the body of facts is still trustworthy:

Evidence & history shows how each one is answered, and the model-free suite of 18 cases that asserts it on what the tools return.
