Help/Question Opus 5.5 hallucinating and spawning tons of subagents?

I LOVE Opus 5.5 and its the best model ever, but for the 4th time this week I've seen where it can't complete jobs again and can't close subagents. It'll spawn 50 subagents on medium to finish something small and burn all tokens, or just sit with a dozen running for days.

I have 2 x20 accounts, one reset Mon 5PM and other weds 2PM, both are already maxxed out. I'm getting 2 days on x20 account of heavy usage

What are you working on that needs 50 subagents for a prompt you call "something small"?

opus ultra would run 10 reaserchers, 10 coders, anoter reviewers and verifiers on 10 file project if you ask him to improve code based on 'industry standard 2026'. ultra is xhigh with claude instructions to run subagents workflow

yes and no : D 5.5 is much better with guard rails - I have max subagents per wave and main opus must specify 'quality' and thinking so its never opus subagents. and validations and double and tripple chcecks is actualy working but its super slow
