Update session - Automate.ax

anthropic.updateSession updates mutable session configuration for subsequent turns.

Example

automations/anthropic-update-session.automation.ts

import { automation, onInvocation, withPrerequisites } from "automate.ax"
import { anthropic } from "automate.ax/anthropic"

export default automation("Update session", () => {
  withPrerequisites(onInvocation(), () => {
    anthropic.updateSession({
      sessionId: "session-id",
      title: "Repository review",
    })
  })
})

Inputs

Requires sessionId. You can patch title and metadata, replace tools or MCP servers, and update or remove an existing budget. A budget cannot be added if the session started without one. Inputs use public camelCase names and accept signals.

Output and behavior

Returns the updated session. Anthropic requests time out before the action lease and provider mutations are not retried after an uncertain response unless stated otherwise.
