Constraining AI Creativity: How Executable Oracles Ensure Reliable Code Generation

Large language models like Claude and Codex can generate impressive code at superhuman speeds, but they're equally prone to mysterious failures and poor-quality output. The solution lies in executable oracles—tools that constrain an LLM's freedom to make bad choices, such as test suites, compiler testing frameworks, and code quality metrics. This approach is essential for making AI coding agents reliable and trustworthy enough for production environments.
