When an agent session is detected, the Local Explorer API is surfaced automatically — agents can query structured traces, inspect binding state (D1, KV, R2, Durable Objects, Queues), and verify fixes in a single local loop. The runtime-level instrumentation in workerd captures fetch calls, binding interactions, and handler lifecycles with no SDK or code changes required. Traces are stored in a SQLite-backed Durable Object and exposed via a REST API with an OpenAPI schema for agent discovery. Human developers can visualize the same data in the browser-based Local Explorer interface. ## Full article daily.dev links to this article rather than hosting it.
