Added an explicit declaration of the Rpc.__DURABLE_OBJECT_BRAND property

[whoiskatrin]

This is really just a band-aid. The brand should flow through the inheritance chain automatically. I think there is something in how partyserver emits its types or how our bundler generates declarations. We should really investigate in partyserver, but this is it unblock the user

Claude Code Review

Status: Approved with notes

This PR adds an explicit __DURABLE_OBJECT_BRAND property declaration to the Agent class as a workaround for TypeScript type inheritance issues with partyserver.

Assessment: The change is sound. The implementation correctly:

• Uses declare readonly to avoid runtime overhead
• Marks it as @internal
• Documents the purpose clearly
• Uses bracket notation for the brand property name

Notes:

• As the PR author acknowledges, this is a band-aid fix. The root cause should be investigated in partyserver's type emission or the bundler's declaration generation.
• No tests needed - this is purely a type-level fix
• The changeset is properly included

No substantive issues found.

Claude Code Review

Critical Issue:

The code references Rpc.__DURABLE_OBJECT_BRAND without importing Rpc (packages/agents/src/index.ts:306).

Rpc is a global type from @cloudflare/workers-types, but TypeScript requires explicit imports when using namespaced types in computed property names. Add this import:

import { Rpc } from "cloudflare:workers";

Or use a type-only import:

import type { Rpc } from "cloudflare:workers";

Additional Notes:

The PR description acknowledges this is a band-aid and the root cause should be investigated in partyserver. That's fine for unblocking users, but ensure a follow-up issue is created to track the proper fix.
