In the context of Linear, a platform facilitating agent interaction, Leela Senthil Nathan outlines the development of the Agent Interaction SDK, emphasizing the shift from traditional coding to managing context and reviewing outputs as agents become integral to product workflows. Linear's existing infrastructure, including OAuth apps and a robust API, provided a foundation for integrating agents as first-class users with distinct identities and permissions within workspaces. This integration allows agents to be assigned tasks and mentioned in threads, fostering seamless human-agent collaboration while maintaining clear distinctions between them. The introduction of agent sessions streamlines interaction by offering structured responses and tracking states like waiting or working, enhancing transparency and user visibility. The concept of "delegation" was introduced to manage the human-agent responsibility loop, ensuring human accountability while agents perform delegated tasks. Future developments aim to enhance agent capabilities by allowing them to provide more detailed explanations of their actions, supported by structured activity types, all while maintaining flexibility to accommodate evolving agent roles within the platform.
