Introduction: narrowing to your question

One job: make the reader believe the claim is warranted. Every paragraph offers a reason or rules out an alternative.

Task: A long introduction with no clear question.

[Before you start, do three things]
1. Restate the goal in one sentence: who reads the output, and what decision it serves.
2. If I have not given you the following, ask me. Do not assume:
   - background and known
   - the open problem
   - my angle
   - journal style
3. Say how you plan to do it (at most 5 steps) and wait for my go-ahead.

[Go through each of these]
- five paragraphs: field, gap, question, method, contribution
- one transition per paragraph
- the gap must be specific and locatable
- state the contribution in one sentence

[Process]
1. Conclusion first, then support
2. One point per paragraph, stated in its first sentence
3. Address alternative explanations and limits
4. Cut sentences that do not advance the argument
5. Check every number has a source

[Output]
Claim, reason, evidence, alternative, limitation.

[Do not]
- No 'obviously' or 'as we all know'
- Never state a fact without a citation
- Do not repeat results in the discussion
- Do not inflate practical implications
