DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

vault_ids documented as create-only, and deployments can be updated

You'll notice
Useful2 Signal3
Agent SDK Docs

Docs say vault_ids cannot change mid-session, and deployments now have an update endpoint.

What

Session update docs now state that vault_ids is rejected on update even though the SDK exposes it as a parameter, so only agent.tools, agent.mcp_servers, title, metadata and budget can change mid-session. Deployments gain an UpdateDeployment endpoint and deployments.update SDK method.

Details
  • A deployment can carry a budget that is copied onto every session it fires; it can be cleared and added back at the deployment level.
Evidence

` vault_ids is create-only (rejected on update) `

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