We’re in the midst of another abstraction leap. Just like compilers, cloud, and containers before it, AI-generated code started with hype, fear, and broken things, and might still end with progress, but only if we build it right.

As we all know by now, LLMs aren't particularly intelligent; they are just monkeys that sometimes output Shakespeare, but with GPUs instead of typewriters. They’ll generate code with confidence, validate it with tests they wrote themselves (if any), celebrate with a lot of emojis, and call it a job well done.

This talk introduces a working model for AI-assisted development that actually holds up under real-world use. It’s built on three ideas:

The Chasm: the dangerous gap between what we meant and what we asked for.

The Craft: the human skill to spot when AI gets it “technically right” but still wrong.

The Chain: the Intent Integrity Chain, a structured flow of prompt → spec → test → code, where each output is validated externally, by humans or deterministic systems, but never by the same model that generated it.

And what we end up with is a blueprint for building production-ready software with AI, without sacrificing trust or intent.

Trust your knowledge. Trust your tests. Never trust a monkey.

A conference talk arguing that AI-generated code cannot be trusted without a structured verification chain. The speaker introduces the 'intent integrity chain': product requirements are turned into human-readable specs by an LLM, humans review and approve the specs, deterministic algorithms (BDD tools like Cucumber) generate test assertions from those specs, and the LLM implements code until those locked assertions pass. This prevents the model from tampering with tests and closes the 'intent-to-code chasm.' The speaker also addresses the need for context management (via tools like Tesslum) for obscure or proprietary APIs, and presents a fork of SpecKit called 'Intent Integrity Kit' as a practical implementation.
