What it does

Marketing Copywriting is an agent skill from cbrock84/headcount. Writes and edits marketing copy for any surface — homepage, product and pricing pages, ads, emails, and collateral — and sharpens existing copy that is not working. Use this to write or rewrite page copy, tighten a draft, fix copy that is vague or feature-led, adapt one message across formats, or review copy before it ships.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/sources.md`).

It sits in Writing & Content, covering Copywriting and Landing pages. The repository describes itself as: An agent organization structured as a company — 15+ departments, 125+ skills, each independently installable, citing the standards and regulators that settle the question. Runs… The licence is MIT.

When your agent uses it

  • Tasks that involve Copywriting
  • Tasks that involve Landing pages

Example prompts

  • “Use the marketing-copywriting skill to write and edits marketing copy for any surface — homepage, product and pricing pages, ads, emails, and…”
  • “/marketing-copywriting”

Workflow steps

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

  1. Structure — is the order right, and is anything missing or duplicated? Fix this before
  2. Cut — remove every sentence that does not advance the argument. Then cut the first
  3. Sharpen — replace abstractions with specifics, passive with active, hedges with claims.
  4. Read aloud — anything you stumble over gets rewritten. This catches what silent reading does

What it can do on your machine

Read from SKILL.md and the folder at commit 98d1c17. 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

Marketing Copywriting loads about 739 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 398 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~739
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.2k

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.

description
Writes and edits marketing copy for any surface — homepage, product and pricing pages, ads, emails, and collateral — and sharpens existing copy that is not working.

Marketing copywriting

Before writing a word

Settle four things. Copy written without them is decoration:

  • Who is reading, and what they already believe.
  • What one thing they should understand afterward.
  • What they should do, singular.
  • What is stopping them — the actual objection, not the polite version.

Writing

Lead with the consequence, not the mechanism. People buy what a thing lets them do. The feature is evidence for the claim, not the claim.

Specific beats superlative, always. "Cuts invoice processing from three days to twenty minutes" outperforms "dramatically faster" because it can be believed and checked. Every superlative is a claim your competitor also makes.

Write the way the reader talks. Their words, from research or support tickets, not internal vocabulary. If a phrase only exists inside the company, it does not go on the page.

One idea per section, in the reader's order — problem they recognize, why existing options fail, what you do differently, proof, what to do next. Not your org chart's order.

Every claim carries proof nearby: a number, a name, a screenshot, a quote. A page of unbacked claims reads as marketing and is discounted wholesale.

Editing

Edit in passes; doing them at once does none of them.

  1. Structure — is the order right, and is anything missing or duplicated? Fix this before sentences.
  2. Cut — remove every sentence that does not advance the argument. Then cut the first paragraph, which is usually warm-up.
  3. Sharpen — replace abstractions with specifics, passive with active, hedges with claims.
  4. Read aloud — anything you stumble over gets rewritten. This catches what silent reading does not.

Kill on sight

Empty openers ("In today's fast-paced world"), we-focused framing where you-focused works, hedges that weaken a true claim, feature lists with no consequence attached, and any adjective a competitor could equally use.

Sources

references/sources.md in this skill lists the outside authorities that settle the questions here — what each one is authoritative for, and what you may do with it. Check them before answering on anything they cover, and cite what you used. Most are free to read and not free to reproduce; the use note on each is binding.

Never

  • Write before you know what the reader should do next.
  • Edit for elegance before the argument is right. Polished copy for the wrong claim is the more expensive mistake.
  • Approve copy nobody read aloud. Rhythm problems are inaudible on the page.
