Your AI workflow produces results—but how do you know each revision is actually better? Explore Taeho Lee’s approach to building, evaluating, and improving a workflow through repeated checks. Work through what to test, which failures matter, and where a person still needs to inspect the result.

  • How do I set up a useful first evaluation loop?
  • How should I decide which framework is worth studying?
  • My automated checks pass, but the result is still wrong. What am I missing?

Describe the workflow you are building, how you currently check its output, and one failure you want to catch. Use that context to discuss a clearer check or the next revision.

The guidance draws on Taeho’s recorded work with framework selection, evaluation loops, and human inspection of failures that automation can miss.
