What changed: Plan mode now adjusts parallel agent count based on subscription tier instead of using a fixed default
Previous behavior: All users got 4 parallel agents in plan mode (unless overridden by environment variable)
New behavior:
- Free tier: 1 parallel agent (75% reduction)
- Team/Enterprise tier: 3 parallel agents (25% reduction)
- Max subscription with 20x model: 3 parallel agents
- Environment variable override: Still available via
CLAUDE_CODE_PLAN_V2_AGENT_COUNT(1-10)
Impact:
- Free tier users will experience slower plan mode execution
- Premium users retain better parallelism
- Change encourages upgrade to paid tiers for better performance
