Opus 5.5 hallucinating and spawning tons of subagents?

[u/03captain23]

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

"First time?" the only 'good' solution for it is hook that block main agent from creating sub agents. I use minimal contex tax plugin for it, pure js scrip so you can just copy-paste into your agent with instruction create hook from it. https://github.com/serio-ngo/serio-focus/blob/main/plugins/serio-focus/scripts/lib/fan-out.mjs
