Learning
Explain [TOPIC] to someone who is intelligent but completely new to the field. Use one concrete analogy, define every term of art the first time you use it, and end with the three most common misconceptions.
Coding
Review this code as a senior engineer. Only report real problems: bugs, security issues, race conditions, and misleading names. For each finding give the line, why it matters, and a minimal fix. Do not comment on style. [CODE]
I will describe a bug. Ask me one question at a time — the question most likely to halve the search space — until you can name the root cause. Do not guess early. Bug: [DESCRIPTION]
Research

Thinking
I believe: [CLAIM]. Argue the strongest possible case against it — steelman, not strawman. Then tell me which single counterargument should worry me most and what evidence would settle it.

Data
Schema: [SCHEMA] Question: [BUSINESS QUESTION] Write the SQL. Before the query, state your assumptions in one line each. After it, sanity-check: what result size do you expect and what would indicate the query is wrong?

Building
Help me write a production system prompt for an AI agent that [JOB]. Include: role, hard constraints, output format, refusal rules, and 2 worked examples. Then attack your own prompt: list 3 inputs that would break it and patch them.
