feat(agents): stubs carry caller context across Agent, Lifecycle Object, and facet RPC; add getStubByName

[mattzcarey]

Summary

Stubs handed out by the SDK now tell the callee who is calling. Every method call on a stub from getAgentByName(), dynamicAgents.get(), subAgent(), parentAgent(), or getSubAgentByName() carries the caller's identity plus optional context hints, readable on the callee as getCurrentAgent().caller.

const worker = await getAgentByName(env.WorkerAgent, id, {
  context: { requestId }
});
await worker.run();

// inside WorkerAgent.run()
const { caller } = getCurrentAgent();
// { kind: "agent", className, sessionId, sessionName, context: { requestId } }
// or { kind: "external", context } from a Worker handler

New getStubByName() returns the raw Durable Object stub with the same startup guarantee and no caller context, for the cases where the stub must stay a runtime Fetcher (see trade-offs).

Why the runtime can't do this yet

Verified against workerd source (src/workerd/api/worker-rpc.c++, actor-state.c++):

• Trace linking across DO and facet RPC is already native (callerSpanContext on every call, facet subrequests carry the user span parent). Nothing to do there.
• There is no per-call metadata channel to JS, no span-context accessor, and AsyncLocalStorage is lost on every RPC hop. So the SDK's own caller identity has to ride in the call.
• JS RPC dispatches only prototype members of a class instance and refuses own properties (tryGetProperty). That is why the callee entry points are defined on the host class prototype at Lifecycle.install time rather than installed per instance like fetch/alarm.
• Facet stubs are ordinary Fetchers on the same RPC path (DurableObjectFacets::get → FacetOutgoingFactory), so they get the same treatment.

How it works

• agent-stub.ts: wrapAgentStub proxies a stub. Method calls go to _cf_invoke(method, args, caller) on the callee and open an agents.rpc.call span. id, name, fetch, connect, disposal, JS-internal probes, and _cf_/__unsafe_ members pass straight through.
• lifecycle/rpc-entry.ts: Lifecycle.install defines _cf_invoke, _cf_rpcIdentity, and __unsafe_ensureInitialized on the host class prototype once, leaving any the class already declares untouched (Agent keeps its facet-aware identity). _cf_invoke re-enters the invocation context with caller attached and uses the same member rule as a native stub. It does not force lifecycle startup, so a re-created instance keeps native startup timing.
• getAgentByName() accepts any Lifecycle Object, not only Agents.
• The facet-parent and getSubAgentByName bridge proxies are wrapped the same way. _cf_invoke travels through them as an ordinary method name, so no per-hop plumbing was needed: the final object sees the original caller.
• The workflow-origin invoke path shares resolveRpcMethod.
• getCurrentAgent() gains caller: AgentCaller | undefined.

Trade-offs

• The stub is a Proxy, not a runtime Fetcher. It cannot be passed to a runtime API that takes a stub (evictDurableObject, ctx.facets.*) or sent as an RPC argument or return value. Both fail loudly. Use getStubByName() for those cases. Documented in get-current-agent.md, lifecycle.md, callable-methods.md, and the changeset. In-repo, the 13 test files that evict stubs now resolve them with getStubByName().
• Untrusted. Caller context is correlation metadata only, never identity or authorization. Documented at every surface.
• Plain Lifecycle Objects identify themselves on outbound calls only while inside a Lifecycle invocation (handler, hook, or a call received through a wrapped stub). Agent wraps its RPC methods in that context; a plain object's method reached over a raw stub reports external. Pinned by a test and documented.
• Caller identity is resolved when the stub is created, not per call. A stub cached across invocations keeps the identity of the invocation that created it.
• Dynamic-agent helpers have no raw-stub variant yet. Facet stubs rarely need to cross RPC, but dynamicAgents.getStub() would be the symmetric addition if that comes up.

Tests

packages/agents/src/tests/rpc-context.test.ts (18 tests): Worker → Agent, Agent → Agent, plain Lifecycle Object in both directions, cross-kind hops, getStubByName as a real Fetcher (and the wrapped stub rejected by evictDurableObject), error surfacing, member guard parity with native stubs, and the full facet tree (root ↔ child ↔ grandchild via subAgent, dynamicAgents.get, both parentAgent branches, and getSubAgentByName).

Full --project workers run green.

Prompted by @durability/transforms (caller/callee transforms over DO RPC). This takes the caller-context idea without the prototype-mutation-by-config or Vite plugin, and keeps a seam that can be replaced if workerd grows a native per-call context channel.
