Review a file upload handler against the team checklist

About this exercise

Review this upload handler against the team's upload checklist and write one numbered line per checklist item, in checklist order, each starting 'Pass' or 'Fail' and naming the code line that shows it. Judge only what the code shows. Plain text, under 110 words.

Common mistakes when you ask AI for this

• A general security review. The AI lists every upload risk it knows instead of checking your 5 items. Try: Say: "One line per checklist item, in order."
• Fail-by-default. The AI marks items as risky even where the code clearly handles them. Try: Add: "Judge only what the code shows; Pass when it's handled."
• Trusting the PR description. The AI accepts 'I followed the checklist' and passes everything. Try: Ask: "Name the code line that proves each result."
• Trusting the AI to count words. AI is bad at counting. Ask for "under 110 words" and it often lands well over. Try: Ask for less than the limit and cap each line: "each line under 15 words, under 80 words total."
• Letting markdown in. AI adds bold and headings by default, and in the PR review they show up as stray symbols. Try: Add: "Plain text only, no bold, no headings."
