Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi! I looked up your request ID - the Multitask parent and the implement subagent both ran Composer 2.5 as selected. The Composer 2.5 Fast runs were auto-spawned Explore helpers, which use the faster Composer variant by default for parallel codebase search (docs).

If you want those Explore helpers on non-Fast Composer 2.5 as well, set Settings → Agents → Subagents → Explore to Inherit from parent so they follow the parent agent’s model.

If you’ve already set Explore to Composer 2.5 (non-Fast) and Fast still shows up, that’s a known Settings-picker bug our team is tracking - no ETA yet. Same pattern here: Sub-Agent going to fast composer model in Plan Mode.
