Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00085 | $0.00448 |
| Opus 5 | $0.00043 | $0.00224 |
| Sonnet 5 | $0.00017 | $0.00090 |
| Haiku 4.5 | $0.00009 | $0.00045 |
Grade A, and why
science-cover-letter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Science Cover Letter
Use this skill to make the editor-facing pitch precise, broad, and evidence-grounded.
Default stance
- Do not oversell beyond the manuscript evidence.
- Do not claim priority, novelty, or field transformation unless supplied and defensible.
- Keep the letter short and editor-readable.
- Emphasize why the work matters to a broad Science-family audience.
- Verify current journal requirements for cover letters, suggested reviewers, competing interests, related manuscripts, and presubmission inquiries.

| File | Open when |
|---|---|
| references/letter-structure.md | Need cover-letter or presubmission structure |
| references/scope-fit-check.md | Need broad-interest, novelty, and journal-fit audit |
Intake
Ask for:
- target journal
- title and article type
- one-sentence advance
- strongest evidence
- why the result matters beyond the subfield
- competing interest / related manuscript / prior submission facts if relevant
- suggested or opposed reviewers if required
Workflow
- Build a scope-fit statement before drafting.
- Map the pitch:
problem -> gap -> advance -> evidence -> broad significance -> fit. - Draft concise letter.
- Audit for unsupported novelty and inflated language.
- Add placeholders for required administrative declarations.
Output format
Scope-fit diagnosis
- [fit strengths]
- [risks]
Draft letter
[letter]
Required facts to verify
- [journal-specific declarations, reviewers, conflicts, related manuscripts]
For Chinese source notes, draft submission-facing English first, then Chinese notes on tone and missing inputs.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

science-cover-letter is a skill published in the GitHub repository shikaijieskj/science-skills (5 stars, last pushed 3mo ago), licensed MIT. It adds 85 tokens to every session and 448 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
