You can have the right idea and the wrong format and waste the whole output.

7.1 Format Anchoring

Do not say "use bullet points." Define the exact structure:

Instead of: "Give me a summary"

"Structure your response as: [3-word headline] → [2-sentence explanation] → [1 concrete example] → [1 failure case or caveat].

Repeat this pattern for each point. Maximum 5 points. No introductory paragraph."

7.2 Fixing Bad Outputs

Problem Fix Prompt
Too long / padded "Remove every sentence that could have been in any answer about this topic. Only keep what is specific to my situation and question."
Too surface-level "This is too high-level. Go one layer deeper on point 3. Give me the mechanism behind it, not the summary."
Too generic "Rewrite this with a specific real-world example at the centre of each point. No abstract claims without an anchor."
Wrong tone "Rewrite this as natural spoken language I could say in a conversation. First person. No bullet points. Under 150 words."
Missed the point "You answered a slightly different question. My actual question was [restate]. Answer only that, in 3 focused bullet points."
