Summary

Claude Code users reported that the Cowork feature can create a roughly 10GB VM bundle under local application support storage, causing severe performance degradation. The issue shows how agent isolation features can introduce operational overhead if storage, cleanup, and resource visibility are not well managed.

What changed

A high-engagement Claude Code issue described Cowork generating a large local VM bundle that slows systems over time.

Why it matters

Isolated agent workspaces are valuable for safety, but they need predictable resource footprints. Enterprise teams evaluating agent workspaces will care about disk growth, cleanup behavior, and observability as much as the isolation model itself.

Evidence excerpt

Agents Radar’s June 6 CLI digest identified Claude Code issue #22543 as a top community item: Cowork created a 10GB VM bundle that users linked to progressive slowdown.
