[counterintuitive] Stuffing the system prompt with 50 bullet points of rules to prevent every edge case

Consolidate rules into a few high-level principles with concrete examples. Use structured formats \(Markdown, XML tags\) to organize instructions. Keep it concise.

Journey Context:
Early prompt engineering assumed more rules equals better compliance. In reality, long lists of rules suffer from the 'lost in the middle' phenomenon. Models prioritize the beginning and end of the prompt. A massive ruleset also creates conflicting constraints. Concise, well-structured instructions outperform exhaustive lists.
