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 | $0.00080 | $0.00730 |
| Opus 5 | $0.00040 | $0.00365 |
| Sonnet 5 | $0.00016 | $0.00146 |
| Haiku 4.5 | $0.00008 | $0.00073 |
Grade A, and why
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 11d 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 — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cover letter
Draft a tailored cover letter for one role. Truthful, specific, concise — never a generic template.
Inputs
~/.dear-hiring-manager/resume.*andprofile.md— the candidate.- The job description + company. If given only a URL, open it and extract the JD first (see
apply).
Procedure
- Read the resume, profile, and JD. Find a hook: the JD's core problem, a recent company launch/news, or a concrete result you can speak to.
- Draft the letter (~300–400 words, 3–4 short paragraphs; under 250 reads thin, over 500 won't get finished):
- Open with a specific hook — NOT "I'm excited/passionate to apply." Tie the first line to company research / the JD's core problem / a concrete result. Specificity earns the second sentence read.
- Body: each paragraph maps one JD requirement to a real, resume-backed story with numbers (2–3 measurable accomplishments, not a skills list). Mirror the JD's own language — "you need X, I did Y" signals a careful read. No claim that isn't in the resume.
- Close with a direct call to action — ask for a conversation.
- Voice + tone: match the candidate's register from the resume — professional but distinct, not a corporate template. Role-fit: engineering → substance over polish; sales → lead with results/numbers; creative → a distinct perspective.
- Humanize. Run the draft through the
humanizeskill — no em/en-dashes, no parenthetical asides, no AI tells, vary sentence length, sound like the candidate. Plus: no generic skill claims without evidence, no over-explaining gaps or pivots, no ATS-breaking formatting (keep it plain text). - Flag it review-me and save to
~/.dear-hiring-manager/runs/<company-role-slug>/cover-letter.md, then deliver it to the form (see below).
Deliver it to the form
- Textarea / "enter manually" → fill the field with the letter text.
- File upload ("Attach") → write the letter to a real file first
(
~/.dear-hiring-manager/runs/<slug>/cover-letter.txt, or.pdf), stage it into.playwright-mcp/(Playwright's sandbox root), upload from there, then delete the staged copy. Accepted types are usuallypdf, doc, docx, txt, rtf.
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 is a skill published in the GitHub repository extrasmall0/dear-hiring-manager (108 stars, last pushed 1mo ago), licensed MIT. It adds 80 tokens to every session and 730 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 2026-08-30.
