Claude Code v2.1.224

Inference geography can be pinned on a Managed Agents agent

You'll notice

Claude API Skill not in their notes

The Claude API docs describe pinning inference geography to us or global on an agent's model.

inference_geo
What

The skill docs add inference_geo, either "us" or "global", set inside an agent's model object rather than at the top level as on the Messages API. It is checked when the agent is saved, when a session is created, and on every turn, and it cannot change for the life of a session.

Details
  • Unlike effort, an inference_geo given in a per-session model override is applied.
  • Omitting it in an override clears the agent's pin.
  • Every model in a multiagent roster must use the same geography.

Pinning inference geography

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
