Report #97507

[counterintuitive] Adding words like 'best', 'perfect', or 'comprehensive' improves output quality

Replace vague superlatives with explicit rubrics and acceptance criteria. Define 'good' in the prompt: required sections, max length, test cases that must pass, forbidden patterns, and how to handle edge cases.

Journey Context:
Anthropic and OpenAI docs both warn that adjectives are not instructions. 'Create the best code' gives the model no concrete signal; it has to guess at your norms. Empirical prompt evaluations show that specifying format, constraints, and evaluation criteria outperforms motivational language. The test is simple: show the prompt to a colleague with no context. If they cannot produce what you want, the model cannot either.
