Cover Letter
Core Rule
A cover letter is an honest, calibrated pitch to the editor, not a sales sheet. It states what the paper contributes, why that fits this venue, and why it matters — using only what the manuscript actually establishes. Never assert significance the paper does not establish. "First study of X" is allowed only if the manuscript defends it; "a major advance," "dramatically outperforms," or a invented effect size is overclaim, and overclaim in the cover letter is the editor's first signal to distrust the paper.
Every number in the letter (tool-call accuracy, task-success delta, sample size) comes from the manuscript's own reported results — never your prior, never rounded up. If the manuscript flags a quantity as [VALUE — verify], the letter does not quote it; it waits. The letter is downstream of the science, never ahead of it.
This skill drafts the letter. It does not change the thesis, the contribution, or any reported quantity — those are Protected Claims (CLAUDE.md → Protected Claims).
When to Use
Invoke with /cover-letter when:
- A manuscript is submission-ready and the venue requires a cover letter to the editor.
- Resubmitting after rejection elsewhere, or submitting a revision that needs a fresh letter.
- You want the contribution and fit argument stated tightly before the final push.
State the venue if it differs from the map: . Otherwise read it from .
