Cover Letter & Editor Pitch (sci-cover-letter)

When to trigger

• Ready to submit and need the editor-facing letter.
• The current letter is a formality ("please find enclosed…") with no argument.
• You need to argue broad significance explicitly to survive triage.

What the cover letter is for

Science editors triage fast. The letter must let an editor decide, in under two minutes, that the paper is plausibly broad enough to review. It is a significance argument, not a summary.

Structure (≈ 250–400 words, one page)

1. Opening claim (2–3 sentences). The one-sentence advance (sci-framing) plus why it matters to a broad audience. Lead with the result, not the background.
2. Why Science specifically (2–3 sentences). Why this is general-interest, not specialist — what communities beyond your own will care and why now (sci-framing why-now trigger).
3. What's new vs. prior work (2–3 sentences). The decisive distinction from the closest prior papers, including any concurrent work. Pre-empt "isn't this known?".
4. Format & logistics (short). "We submit this as a Report/Research Article. The work has not been published and is not under consideration elsewhere."
5. Optional: suggested/excluded reviewers, competing interests, related submissions, and any embargo/press considerations.

The significance paragraph test

The editor should be able to copy your second paragraph into a referee-invitation email. If it reads as specialist or hedged, rewrite it.

Logistics to include

• Statement of originality and exclusivity (not published / not under review elsewhere).
• Manuscript type (Report vs Research Article) and rough length.
• Competing interests declaration (or "none").
• Related manuscripts (yours) in press/under review, if any.
• Suggested reviewers (a few) and opposed reviewers with brief reason, if applicable.
• Any prior submission/transfer history if relevant.

Tone

• Confident, specific, quantified — but not grandiose. Editors discount "groundbreaking/unprecedented".
• No jargon walls; a chemistry editor should grasp a biology letter and vice versa.
• Short paragraphs; the whole letter fits on one page.

Cover-letter pass for Science

Use this as a second-pass capability check. First lock the broad discovery claim, decisive evidence, uncertainty/limitations, and why the result belongs in a general-science weekly; then test whether the manuscript addresses general-science reviewers and editors who ask whether the result changes a broad field, is technically decisive, and can be understood outside the subdiscipline.

• Primary move: Make the letter a routing document: discovery, breadth, decisive evidence, policy/field implication, and compliance in one editor-facing argument.
• Decision ledger: return claim / evidence / blocker / next edit rows so the next pass can patch the manuscript directly.
• Neighbor test: compare against Nature for similar broad-scope novelty, PNAS for academy-wide breadth, specialist journals when the claim is field-internal; if the neighboring outlet has the stronger audience claim, recommend re-routing before polishing.
• Verification floor: before submission-ready advice, re-open resources/official-source-map.md for volatile rules and name the one unresolved fact that could change the recommendation.

Output format

【One-line advance restated】 "..."
【Broad-significance paragraph】 reviewer-invitation-ready? yes/no
【Novelty vs closest prior/concurrent work】 stated? yes/no
【Manuscript type + length】 ...
【Logistics checklist】 originality / COI / suggested-opposed reviewers / related subs
【Next】 sci-submission

Anti-patterns

• Do not summarize the abstract; argue significance instead.
• Do not use unsupported superlatives — quantify the advance.
• Do not omit the originality/exclusivity statement.
• Do not bury the hook below logistics; the first sentence carries the advance.
