What it does

Cover Letter is an agent skill from extrasmall0/dear-hiring-manager. Generate a tailored, truthful cover letter from the user's resume, profile, and a specific job description. Draft it in the user's voice, ground every claim in the resume (no fabrication), map it to the role, flag it for review, and save a copy. Used by the apply skill when a portal has a cover-letter field, or standalone via /cover-letter <job-url.

Its SKILL.md is about 750 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: A Claude Code plugin that fills your job applications from your profile, drafts the cover letter, and leaves Submit to you. Locally. The licence is MIT.

When your agent uses it

  • Tasks that involve Resume and CV writing

Example prompts

  • “/cover-letter”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Read the resume, profile, and JD. Find a hook: the JD's core problem, a recent company launch/news, or
  2. Draft the letter (~300–400 words, 3–4 short paragraphs; under 250 reads thin, over 500 won't get finished)
  3. Voice + tone: match the candidate's register from the resume — professional but distinct, not a
  4. Humanize. Run the draft through the humanize skill — no em/en-dashes, no parenthetical
  5. Flag it review-me and save to ~/.dear-hiring-manager/runs//cover-letter.md,

What it can do on your machine

Read from SKILL.md and the folder at commit ff6c26b. 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

Cover Letter loads about 749 tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 363 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~749

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.

Generate a tailored, truthful cover letter from the user's resume, profile, and a specific job description. Draft it in the user's voice, ground every claim in the resume (no fabrication), map it to the role, flag it for review, and save a copy. Used by the apply skill when a portal has a cover-letter field, or standalone via /cover-letter <job-url>.

Cover letter

Draft a tailored cover letter for one role. Truthful, specific, concise — never a generic template.

Inputs

  • ~/.dear-hiring-manager/resume.* and profile.md — the candidate.
  • The job description + company. If given only a URL, open it and extract the JD first (see apply).

Procedure

  1. 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.
  2. 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.
  3. 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.
  4. Humanize. Run the draft through the humanize skill — 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).
  5. 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).
Show full SKILL.md (104 more words)Show less

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 usually pdf, doc, docx, txt, rtf.

Rules

  • Truthful: every claim traces to the resume/profile — no invented employers, titles, dates, or numbers.
  • Tailored to THIS JD/company — if it could be pasted into another application unchanged, it's too generic.
  • The human always reviews before Submit; the draft is a flagged starting point.
  • Flat-file: the saved copy is human-readable Markdown.
