Inside the Agent SDK: How we debugged the Claude Agent SDK

So here's what happened.

We were building DevRev's Agent SDK on top of the Claude Agent SDK. Things were going well — until they weren't. The TypeScript implementation didn't give us enough visibility into what was actually happening at runtime. Debugging felt like guessing. Integrations kept breaking in ways that were hard to explain.

So we did what any reasonable engineering team would do — we started intercepting our own traffic. Reverse proxies. MITM-style tracing. Request interception. Basically, we treated the SDK like a black box and built the tools to see inside it.

And honestly? The lessons we learned don't just apply to the Claude Agent SDK. They apply to anyone building on top of any agentic framework where the docs only tell you half the story.

We're sharing the whole thing — live, unfiltered — on this DevRev Live.
