What it does
Epsl Cover Letter is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when writing the cover letter and editor-facing metadata for an Earth and Planetary Science Letters (EPSL) submission. EPSL is run by a team of subject editors who screen for frontier significance and letters fit, so the letter must land the process-level advance, steer to the right editor, and supply clean suggested reviewers. It drafts the letter; it does not contact editors.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Business, Finance & HR, covering Resume and CV writing. The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. ｜ 覆盖主流期刊的… The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Epsl Cover Letter loads about 1.3k tokens when it runs. Until then it costs about 101 tokens; SKILL.md has 570 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Use when writing the cover letter and editor-facing metadata for an Earth and Planetary Science Letters (EPSL) submission. EPSL is run by a team of subject editors who screen for frontier significance and letters fit, so the letter must land the process-level advance, steer to the right editor, and supply clean suggested reviewers. It drafts the letter; it does not contact editors.
Cover Letter & Editor Pitch (epsl-cover-letter)
EPSL manuscripts are handled by an editor whose own research sits near the paper's sub-field — geochemistry, geophysics, geodynamics, planetary science (the current editor roster changes; re-check it on the journal site). Your letter is read by a scientist who can evaluate the claim directly, so it must be a precise scientific argument for significance, not marketing. Its three jobs: state the frontier advance, demonstrate letters fit, and make the editor's reviewer search easy.
When to trigger
- Writing the cover letter for a new EPSL submission
- Choosing the editor whose remit matches the paper (where the system allows a preference)
- Assembling suggested and opposed reviewers with conflict statements
- Re-pitching after a desk decline at another high-bar venue
What the letter must do
- Open with the advance, quantified. Two or three sentences: the process question, what your result establishes, and the number that carries it — written for a scientist-editor, without superlatives.
- Argue portability explicitly. One sentence on why readers beyond the study region or method community need the result; this is the desk-screen axis regional studies fail.
- Show letters fit. Confirm one decisive result, main text within the cap, no companion manuscript in play.
- Flag the cross-disciplinary reviewer pairing. If the paper joins two sub-fields, say so and suggest reviewers from each — it tells the editor you understand how EPSL will referee it.
- State integrity basics. Original work, not under consideration elsewhere, all authors approve, preprint status if any, data deposited (name the repositories), competing interests declared.
- Suggest clean reviewers. Several qualified names with no recent co-authorship, shared institution, or advising ties; opposed reviewers named soberly with a one-line reason if needed.
The subject editor's silent questions
| Editor asks silently | Weak letter | Letter that survives |
|---|---|---|
| Is this a frontier advance? | "we present new data from X" | "this is the first measurement that separates hypothesis A from B, at ±… precision" |
| Will non-specialists care? | portability unstated | "any interpretation of [archive/process] must now correct for…" |
| Is it a Letter? | length/scope unmentioned | "a single result, 5,900-word main text" |
| Can I referee it fairly? | reviewer list from one clique | reviewers spanning both sub-fields, conflicts stated |
| Are the data real and open? | silence | "full tables at EarthChem (DOI), code at Zenodo (DOI)" |

Worked micro-example (illustrative — pitching the detrital-lag paper)
- Weak hook (desk-decline risk): "We report 600 new detrital-zircon U-Pb ages from the X Basin together with bedrock thermochronology, and discuss the provenance of the basin fill." An editor files this under regional provenance.
- Strong hook: "We provide the first direct measurement of the lag between mountain exhumation and its appearance in the sedimentary record — 5.0 ± 1.2 Myr (illustrative) — by dating both ends of one sediment-routing system. Detrital archives are read worldwide as if this lag were zero; our result makes that reading correctable." Process, number, portability — in three sentences.
The conversion move is always the same: replace what was measured where with what everyone else must now do differently.
Anti-patterns
- A letter that inventories the dataset but never states what it decides
- "Novel," "unprecedented," "paradigm" doing the work that a number should do
- Ignoring the regional-study objection when the title contains a place name
- Suggesting only reviewers from the authors' collaboration network
- Omitting data-deposition, preprint, or competing-interest statements
- A letter longer than a page
Output format
【Hook】advance + number + portability in ≤3 sentences
【Letters fit】one result + within cap + no companion paper
【Editor】subject remit matched (re-check current roster)
【Reviewers】suggested (both sub-fields) + conflicts stated; opposed if any
【Integrity】originality / authors / preprint / data DOIs / COI
