GenCoord: Executable Commitments for Embodied LLM Agents under Private Information

GenCoord is a decentralized protocol for embodied language‑model agents that turns the division of work into the communication message itself. By pairing a sender’s skill path with a partner’s continuation in a short domain‑specific language, agents create commitments that link delivery to subsequent work, allowing fulfillment to be verified separately from task success. Experiments in Minecraft show that GenCoord matches free‑form communication performance while cutting median commitment time by 68.2 % and reducing output tokens, demonstrating that structured, work‑based messages can improve efficiency in embodied cooperation.

Who Holds the Pen? Let Specifications, Not Agents, Sign Off

The paper argues that large language model agents should not be the sole authority on whether they have satisfied a task. It identifies two gaps—understanding–execution and state–authority—where agents may claim completion without actually meeting the specification. The authors propose SpecHarness, a framework that separates agent proposals from authoritative state by requiring evidence from qualified providers to confirm compliance, and demonstrate its effectiveness on guideline‑following and artifact‑generation tasks.
