Six Open Standards Aim to End AI Agent Lock-In Across Platforms

Teams building AI agents often find their work trapped inside a single vendor's platform, with system prompts, tool configurations, and approval rules stored in proprietary formats that cannot be easily moved. This lock-in resides not in the underlying model — which can be swapped freely — but in the 'harness,' the runtime software that manages context, executes tools, and enforces permissions. A set of six emerging specifications seeks to make these harness components portable: the Model Context Protocol, Agent Skills, Agent2Agent, the Open Agent Profile, the Agentic Graph Specification, and the Agent Approval Interchange Specification. The effort draws a parallel to how Apache Iceberg resolved data storage lock-in by establishing open table formats any engine could read. The author, who works at data platform company Dremio and co-authored three of the six specs, argues that standardising the harness layer is the next necessary step for teams to truly own the AI agents they build.
