This article explores building efficient AI agent evaluation systems. The author stresses that while models constantly improve, evaluation remains crucial. It advocates starting with end-to-end (E2E) evaluations, defining success criteria and outputting simple yes/no results to quickly identify problems, refine prompts, and compare different model performances. Next, "N-1" evaluations, simulating previous user interactions, can directly pinpoint issues, but require maintaining updated "N-1" interactions. Checkpoints within prompts are also suggested to verify LLM adherence to desired conversation patterns. Finally, the author notes that external tools simplify setup, but custom evaluations tailored to the specific use case are still necessary.

The author undertook the challenge of writing a C compiler in just 500 lines of Python, targeting WebAssembly. To achieve this, a single-pass compilation strategy was employed, foregoing an Abstract Syntax Tree (AST) and generating code directly during parsing. This resulted in a concise compiler, but at the cost of several features, including floating-point numbers and structs. The resulting compiler successfully compiles and runs simple C programs, demonstrating the feasibility of a single-pass approach.
