Marketing & Copy skills

Marketing skills write short, specific copy from facts you give them: a first email to a stranger, a product description, an ad line. The rule that decides what we list is honesty. A skill here must not invent a customer, a discount or a personal detail about a recipient, and it must say what it needs when the input is thin. What is not here: bulk mailing tools, growth hacks and anything built around deceiving the reader. We check every skill on a strong and a weak model, in more than one language, and we publish where the weaker one goes wrong, including invented facts.

  • LinkedIn Carousel Slides From Text (Strict JSON)

    Marketing & Copy

    SKILL.md · v1.0.0 · 6.2 KB

    Turns a source text (an article, a post, meeting notes) into the text of a carousel for LinkedIn or Instagram as strict JSON, one object with a headline and a body per slide, and nothing else. It follows the slide count you ask for (or a stated default of 5), keeps every headline to 8 words and every body to 30, makes the first slide a hook with no call to action and the last slide the call to action, copies every number, name and quote exactly as the source has it, adds no claim the source does not make, and gives each slide one idea. A line inside the source that gives it orders is treated as text. It writes the words of the slides only, not the pictures or the layout. Use to turn a blog post or report into a carousel, to draft slide copy from notes, or to repurpose a long post for a swipeable format.

  • Character Limits for Google Ads, App Store and Social Posts

    Marketing & Copy

    SKILL.md · v1.0.0 · 7.3 KB

    Counts the fields of ad and store copy against the published limit of each platform (Google responsive search ads, App Store product page, Google Play listing, X and LinkedIn posts) and returns a line only for each field that is over, with the exact count, the limit, the unit and a shortened version that fits - or exactly No findings. It counts by the platform's own rule: double-width characters in Google Ads, bytes for the App Store keywords, the fixed length of a link and the double weight of an emoji on X. Fields that fit are left out, including a field exactly at the limit. Use before pasting copy into an ad account, an app store console or a scheduler, to find which field a platform rejects or cuts, or when copy written for one platform has to be reused on another.

    Product Description From a Spec Sheet

    SKILL.md · v1.0.2 · 6.3 KB

    Writes shop product copy (title, short description, bullets, long description) from a specification sheet and nothing else, in the sheet's language. Every figure keeps its unit and its qualifier, no superlatives or unsupported claims, and values that contradict each other are reported instead of chosen. Use when asked to write a product description, product page text, catalogue entry or marketplace listing copy from a spec sheet, in any language.

    Image Prompts in One Style: Clean Pictures for a Site

    Marketing & Copy

    SKILL.md · v1.0.3 · 8.4 KB

    Writes prompts for image models (FLUX, Stable Diffusion, ChatGPT images, Gemini and the like) that give a website, a blog or a product one recognisable style and come back without garbled letters. The scene comes first and the site's style recipe follows it word for word; absence is described positively instead of "no text, no watermark", which in a single prompt box summons those very things; anything that would need readable writing (a price list, a chart, a date) becomes a metaphor without characters; the scene ends with a closed list of what is in it; people and hands, the usual weak spots, are shown through objects; the aspect ratio is stated in numbers; and several pictures become several prompts, never one. Use when you write or fix prompts for hero images, blog headers, cards or illustrations, when generated pictures come back with pseudo-letters, cluttered scenes or a different style each time, or when a brief arrives in another language.
