Marketing Copy Agent Skill

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.
