Claude Code lowers the medium dynamic-workflow guideline from 15 agents to 10, and defaults Pro plans to small
Claude Code Changelog·medium signal
2.1.271 changes the default dynamic workflow size to small on Pro plans and drops the medium size guideline from 15 agents to 10. The same release improves dynamic workflows to pause when you hit your usage limit and continue automatically when it resets, instead of dropping the affected agents. Read together, these are Anthropic tuning fan-out width down while making the fan-out survivable, which matters for anyone running scheduled multi-agent jobs against a subscription quota.
