Code as Agent Harness: Survey Positions Code as the Substrate for Executable Agent Systems (159 HF upvotes)
Multi-institution (42 authors)
A comprehensive survey positioning code not merely as agent output but as the operational substrate for agent reasoning, action, environment modeling, and execution-based verification. Organized around three layers — harness interface, harness mechanisms (planning, memory, tool use), and multi-agent scaling — covering coding assistants, GUI automation, embodied agents, scientific discovery, and enterprise workflows.
