What it does

Marketing Copy is an agent skill from scarletkc/agents. Write outbound promotional copy for a product or project: launch and update posts for community platforms and social media, store page descriptions and short blurbs, landing page headlines and calls to action, press-style announcements, and the naming of a product for another language or market.

Its SKILL.md is about 1.3k 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 Frontend & Design, covering Copywriting and Landing pages. The repository describes itself as: Shared standards and reusable skills for Claude Code, Codex CLI, and other AI coding agents. The licence is Apache-2.0.

When your agent uses it

  • Revising anything aimed at people who do not use the product yet
  • When deciding whether a link
  • Unreleased detail can appear in public copy

Example prompts

  • “/marketing-copy”

What it can do on your machine

Read from SKILL.md and the folder at commit eb55005. 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 Copy loads about 1.3k tokens when it runs. Until then it costs about 160 tokens; SKILL.md has 651 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~160
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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.

Write outbound promo copy that stays truthful, discloses only what may be public, and earns attention without hype.

Marketing Copy

Outbound copy reaches people who have no product context and no reason to finish reading. It is also the surface where a disclosure mistake is permanent: a post can be deleted, a screenshot of it cannot. Both facts push the same way, toward concrete claims a reader can check.

This covers copy aimed outward. Product-internal strings and documentation follow ux-writing; matching the author's personal voice is talk-like-scarletkc.

Disclosure comes first

Decide what may be public before writing, because the draft is where a leak gets normalized.

  • Keys, invite codes, and credentials are not copy. Anything that grants access belongs in the channel that distributes it under its own terms, never inline in a public post, and never pasted into a draft "to be removed later".
  • An unreleased or unlisted URL stays unlisted. A link that has not been announced is not published just because it resolves. The same applies to endpoints, staging hosts, and pages reachable only by those already told.
  • Platform rules bind the copy, not just the account. Each destination has its own limits on what may be promoted, linked, priced, or given away, and they differ between platforms carrying the same post. When a rule makes a detail unpostable, drop the detail; hinting at it obliquely to stay within the letter of the rule is the same violation with worse writing.
  • Unshipped work is not a feature. Roadmap items, planned platforms, and anything gated behind review get described as what they are, or left out. Announcing a date creates an obligation the copy cannot see.

When a constraint blocks a detail the requester wanted to include, say which detail and why, and let them decide, rather than quietly dropping it or quietly keeping it.

Claims stay traceable

Take substance from what actually shipped: the changelog, the commit range, the release notes. Every concrete claim traces to one of those, and an adjective that carries a claim owes what "adjectives need evidence" in ux-writing asks of it. What outbound adds is the exchange rate: specifics beat adjectives at the same length, because a number, a mechanism, or a before-and-after carries conviction that "greatly improved" cannot, and it survives a reader who checks.

Never invent a metric, a benchmark, a user count, a review quote, or a comparison against a named competitor. When the honest version is thin, that is information about the release, not a prompt to inflate it.

Writing for someone who has never seen it

Say what the thing is before saying why it got better. A reader who cannot tell what the product does has no way to care that it improved, and an update post aimed at existing users reads as noise to everyone else. When a post has to serve both audiences, the identifying sentence costs one line and buys the rest.

Revolutionary, seamless, game-changing, and unleash have stopped carrying meaning in this genre: they appear in every launch post regardless of what shipped, so a reader skips them to look for the specifics underneath. Write the specifics instead. Manufactured urgency and invented scarcity fail the same way, and cost more when the deadline turns out to be arbitrary.

A post may legitimately carry several asks, since a launch often wants the wishlist, the community, and the download at once. Order them by what this particular reader can act on now, and let each one be findable rather than competing for the same sentence.

Naming across languages

A product name rendered for another market is a naming decision, not a translation. Check that the candidate is pronounceable and memorable for that audience, carries no unintended meaning, and does not collide with an existing product in the same category. Prefer a name the audience can search, and once a rendering has shipped anywhere public, keep it stable. A second name for the same product splits every search result and every conversation about it.
