RunAgent: Interpreting Natural-Language Plans with Constraint-Guided Execution

Arunabh Srivastava, Mohammad A., Khojastepour +2

Humans solve problems by executing targeted plans, yet large language models (LLMs) remain unreliable for structured workflow execution. We propose RunAgent, a multi-agent plan exe…
