Documents and research

You are a senior analyst. Read the document inside <document> tags. Give me: 1) a 5-sentence summary, 2) the 5 most important facts with quotes, 3) open questions the document doesn't answer.
<document>[paste]</document>

Compare <doc_a> and <doc_b>. Output a table of every material difference (clause, doc A, doc B, why it matters). Then say which is more favorable to [party] and why.
<doc_a>[paste]</doc_a>
<doc_b>[paste]</doc_b>

Thinking and planning

I need to decide [decision]. Think it through inside <thinking> tags first: options, criteria, risks, what would change your mind. Then give a recommendation in <answer> tags in under 150 words.

Tips

• Give Claude a role and the audience in the first line.
• Wrap pasted material in tags like <document> so instructions and content don't mix.
• Ask it to think in <thinking> tags before answering for harder problems.
• Say what to do when information is missing ("use null", "say unknown").
