Benjamin Taylor b8c0ce99ed fix(deps): bump @ag-ui/core family 0.0.57 -> 0.0.58 (OSS-924)
Our packages pinned @ag-ui/{core,client,encoder,proto} exactly at 0.0.57.
@ag-ui/mastra@1.1.2 imports `tokenUsageFromAiSdkUsage`, which only exists
from @ag-ui/core@0.0.58, while declaring a loose `>=0.0.44` peer. Any app
that pins core to whatever our runtime pins therefore installs cleanly and
then fails at bundle time on a missing export.

0.0.58 is additive over 0.0.57 (TokenUsage schema + helpers, optional
`usage` field) plus one input-widening: TOOL_CALL_START.parentMessageId now
accepts null and coerces it to undefined instead of rejecting it.

That widening makes two channels-core negative-control tests stale. They
asserted that a null parentMessageId aborts a run when sanitizeAgentEventStream
is not applied -- the upstream bug the sanitizer works around. Core 0.0.58
fixes it upstream, so those runs now succeed; the tests are updated to assert
the new behavior. The sanitizer is kept: it normalizes null to "" whereas core
coerces to undefined, and it is public API.

Scope note: showcase/integrations and the examples that pin published
@copilotkit versions are deliberately NOT bumped. They have no @ag-ui
override, so raising only their direct pin would hoist 0.0.58 at the root
while @copilotkit/* keep nested 0.0.57 copies -- turning one coherent copy
into a split. They pick up 0.0.58 when they bump their @copilotkit pins.

Trusted Inspector metadata

An Intelligence-backed v2 runtime can proxy trusted project and license context to the Inspector. The runtime advertises this support with inspectorMetadata: true in its runtime-info response.

Runtime mode Request
Multi-route GET {basePath}/inspector-metadata
Single-route POST {basePath} with { "method": "inspector/metadata" }

A valid response is a sanitized InspectorMetadataV1 JSON object with Cache-Control: no-store, private. Missing data, an unsupported schema, a non-Intelligence runtime, or a provider failure returns 204 with the same cache policy. This optional request never changes the main runtime connection state. The upstream Intelligence request has a five-second deadline; a timeout uses the same private 204 path.

Runtime keeps schemaVersion: 1 and returns the object normalized by Shared. Older producers may omit usage.expiringSoonCount, and 0 stays a known zero. If this optional leaf is malformed, Shared removes only the leaf and keeps valid base usage and sibling modules. Runtime does not calculate or cache expiry, and older consumers ignore the additive leaf.

The Intelligence request uses the API key configured on the server-side CopilotKitIntelligence client. The proxy does not forward browser headers or cookies to Intelligence, and it does not expose provider error bodies to the browser. Browser headers and configured fetch credentials still apply between @copilotkit/core and your Copilot Runtime, so you can protect the runtime route with your normal app auth.

Deploy the Intelligence producer before releasing a runtime that advertises the capability. New runtimes treat a 404 from an older Intelligence App API as compatible absence and return 204 to the client.

Intelligence identity and Memory

An Intelligence Runtime supports web only, Channels only, or both. Web routes need identifyUser(request). Each Channel has its own identifyUser policy in createChannel. A Channels-only Runtime omits the web callback and exposes no functional web routes.

const runtime = new CopilotRuntime({
  agents,
  intelligence,
  identifyUser: authenticateApplicationUser,
  channels: [supportChannel],
  memory: {
    access: async ({ request, user, consumer }) => {
      const role = await roleFor(request, user);
      if (role === "blocked") return null;
      return consumer === "client"
        ? { user: "read", project: "none" }
        : { user: "read-write", project: "read" };
    },
  },
});

The callback runs once per web request. Its user owns ordinary web Threads and is reused for agent and browser Memory policy. Adding memory exposes the browser Memory routes and agent tools under the same policy. A denial returns 403; a policy error fails the request. Omitting memory hides the browser routes and does not attach Memory tools.

exposeMemoryRoutes and CopilotKitIntelligence({ enableEnterpriseLearning: true }) remain for one compatibility window. New code should use memory.access.

Analytics & Privacy

CopilotKit uses Scarf for anonymous usage analytics to help improve the product. Scarf handles all privacy compliance and does not store raw IP addresses. This helps us understand how CopilotKit is being used and prioritize improvements.

Opting Out

To disable analytics, set the environment variable:

export COPILOTKIT_TELEMETRY_DISABLED=true

Or use the DO_NOT_TRACK standard:

export DO_NOT_TRACK=1
