this new open-source github repo gives agents a persistent workspace beyond the conversation, built around an agent harness.

Cohub is an open-source agent OS that gives agents one shared place for files, sessions, tools, scheduled tasks, and reusable context.

I like the 2-layer memory model Cohub ended up with.

The context hub is curated organizational memory. A Space is the working state of one project.

Those need very different write policies.

If every temporary script, draft, failed attempt, and personal note enters global memory, retrieval quality eventually collapses. But deleting all of that after a task finishes is wasteful too, because the failed attempts and intermediate artifacts often explain how the result was reached.

So Cohub keeps the full work-site inside the Space and promotes only durable knowledge into the Hub.

That gives the harness two retention horizons: preserve execution state cheaply, curate shared judgment selectively.

A lot of agent memory systems seem to jump straight from conversation history to "long-term memory." This is a more useful distinction.

An organization probably does not need one giant memory. It needs somewhere agents can make a mess, and somewhere they cannot.
