How Harnesses Implement Skills and MCPs (blog.lawrencejones.dev)

Incident.io has launched a new project called "Extensions," which allows customers to integrate Model Context Protocols (MCPs) into their platform and equip them with skills that dictate how to use these tools effectively. This significant development empowers users to leverage functionalities similar to those offered by advanced AI models like Claude and Codex, facilitating a seamless exchange between users and various APIs. The Extensions project addresses previous challenges of passive technology consumption by embedding skill support into their agent harnesses and actively seeking user feedback to ensure better performance and understanding of integrated skills. Key technical aspects include the use of skills, which are structured instructions that aid agents in utilizing MCPs effectively. By standardizing access to essential tools and providing instructional resources, Incident.io aims to enhance user capabilities while minimizing errors when interfacing with APIs. Moreover, the project underscores the importance of careful prompt engineering, highlighting potential pitfalls in naive prompt design. This innovative approach not only streamlines integration processes but also fosters a more knowledgeable and capable AI ecosystem, promoting best practices within the rapidly evolving field of AI/ML.
