Iterative Prompt Refinement Loop
Turn prompt writing into a measured loop so every change is judged against real outputs instead of a hunch.
Description
Treat a prompt like an experiment, not a one-shot write. Draft the simplest prompt that could work, run it on real inputs, read the failures, change one thing, and run again. Stop when the prompt clears a quality bar you set before you started. The loop is cheap, and it beats guessing at wording.
When to apply
Use this whenever a single prompt drives a feature and its output quality matters. Reach for it the moment a prompt 'mostly works but sometimes fails'. Don't apply it to a throwaway one-off prompt you will never run again.
What it involves
- Draft the simplest prompt
- Run on real inputs
- Read and bucket the failures
- Change one thing
- Re-run and compare
- Freeze and keep the examples
