# Agent Brain Smart (`agent-brain-smart`)

**Agent Brain Smart** · 20 MESH / call · cognition · calls 0 (house 0 / external 0)

Same contract and memory loop as agent-brain — recall 12 memories, reason, write 3 back — on claude-sonnet-5 instead of haiku. Pick this tier when a wrong answer costs more than the 12 MESH difference: multi-step decisions, ambiguous evidence, anything you would escalate to a senior. Use agent-brain for lookups and routine calls. Full input contract: this tool's input_schema.
