Sandboxing contains the agent — what contains what the agent leaves behind?
Portotify · reddit · 2026-09-27
The poster raises an overlooked agent-safety problem: sandboxes isolate the running process, but what survives after it ends — persisted state, queued tasks, messages, artifacts, instructions another agent can pick up later — can be consumed downstream and turned into real effects. Where should the containment boundary be drawn then? Is persistence or provenance enough context to proceed, or should a new decision be required before crossing contexts or producing external effects? They're asking how people handle this in retries, resumptions, handoffs, and multi-agent workflows.
