Write flux comments only where they clear the threshold

About this exercise

You're writing October flux comments for five expense lines. Write a prompt for five plain-text lines, one per account, in the format "Account: comment". Only comment when the change from September is both more than 10% and more than $1,000. Otherwise write exactly "No comment". A commented line states the dollar and percent change and the cause from the notes, under 30 words.

Common mistakes when you ask AI for this

• Only checking percent. The AI comments on Professional fees (+18%) though it's under $1,000. Try: Say: "Both tests: more than 10% AND more than $1,000."
• Commenting on everything. The AI writes a comment for every line, including Rent. Try: Add: 'Otherwise write exactly: No comment'.
• Cause with no amounts. The AI writes causes but skips the dollar and percent change. Try: Say: "Give the dollar change, percent change and cause."
• Markdown extras. The AI adds bold labels, headings and a closing note. Try: Say: "Plain text, no bold. Output only the lines asked for."
• Trusting the AI to count words. AI is bad at counting and runs past word limits. Try: Ask for fewer words than the real cap and keep each line short.

What a strong prompt includes

• States both tests
• Says what to write otherwise
• Asks for numbers and cause
• Limits to the notes
• Sets format
