Your AI Coding Assistant Is Hallucinating Your Internal SDKs (Here's How to Fix It)

See how Helix Code Intelligence stops AI coding assistants from hallucinating when working with internal SDKs by indexing your real libraries and making them available to agents.

If you've ever asked an AI coding assistant for help with an internal SDK and gotten back perfectly formatted code that's completely made up, you're not alone. Every enterprise developer has been there.

In this video, Phil Winder walks through a real example of what happens when your coding assistant has zero knowledge of your internal libraries.

The problem

Using a fictional internal payment platform called Helix Pay, Phil shows how an AI agent plans and generates code without access to the actual SDK. The agent invents its own types, its own patterns, and none of it is real. The entire implementation is hallucinated because the SDK doesn't exist on the internet. There are no Stack Overflow answers, no blog posts, no training data. The LLM is flying completely blind.

The fix

Phil then connects Helix Code Intelligence, which indexes the real SDK and makes it available to the AI agent. Same prompt, same task, completely different result. The second attempt actually imports and uses the official Helix Pay SDK correctly.

What the video covers

• Why AI coding assistants hallucinate when working with internal SDKs
• A side-by-side comparison of generated code with and without codebase indexing
• How Helix Code Intelligence indexes and exposes internal libraries to AI agents
• What the resulting pull requests actually look like

If you're building with internal platforms and want your AI tools to actually be useful, this one's for you.
