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 | $0.00000 | $0.02311 |
| Opus 5.5 | $0.00000 | $0.00924 |
| Sonnet 5.5 | $0.00000 | $0.00462 |
| Haiku 4.5 | $0.00000 | $0.00231 |
Grade A, and why
cover-letter-writer 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 271 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cover Letter Writer
The cover letter is your manuscript's first impression on the editor. It is a persuasive document that must convince the editor to send your paper for peer review — not a restatement of your abstract.
What Editors Look For
Editors read cover letters to answer three questions:
- Is this paper in scope? — Does it fit the journal's mission and readership?
- Is it novel and significant? — Does it advance the field meaningfully?
- Is it ethically sound? — Are there conflicts of interest, prior presentations, or related submissions?
A good cover letter addresses all three in under one page.
The Universal 5-Paragraph Model
Paragraph 1: Hook + Identification
Purpose: Capture attention and identify the manuscript.
Elements:
- Journal name (proves you've targeted the submission)
- Manuscript type (research article, review, case report)
- Title
- Why this topic matters now (the hook)
Example:
Dear Dr. Smith,
We are pleased to submit our manuscript, "Gut Microbiome Alterations in Early-Stage Alzheimer's Disease: A Prospective Cohort Study," for consideration as a Research Article in Nature Medicine. With 50 million people affected by dementia worldwide and no disease-modifying treatments available, understanding modifiable risk factors has never been more urgent.
Paragraph 2: Novelty and Significance
Purpose: Demonstrate why your paper deserves peer review.
Elements:
- What gap does it fill?
- What is new compared to existing literature?
- What are the key findings?
- Why do they matter?
Do NOT repeat the abstract. Instead, narrate the significance.
Example:
Our study addresses a critical gap: while late-stage Alzheimer's pathology is well-characterised, the gut-brain axis in the preclinical phase remains poorly understood. In a cohort of 200 cognitively normal adults followed for 5 years, we identified specific microbial signatures that predicted conversion to mild cognitive impairment with 78% accuracy. These findings suggest that microbiome modulation could be a viable early intervention strategy — a hypothesis testable in clinical trials.
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.

cover-letter-writer is a skill published in the GitHub repository muhammad1438/academic-writer-skills (7 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,311 tokens. 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.
