Announcement Card Skill
A great announcement is short, concrete, and easy to skim — the opposite of a press release. This skill
writes a tight announcement built to be shared as an image: a bold headline, a one-line "what & why it
matters", a few proof points, and a clear next step. In the playground it exports beautifully via 🖼️ Save
as image.
Required Inputs
Ask for these only if they aren't already provided:
What you're announcing — the launch / milestone / feature / hire / funding / win.
Why it matters — the benefit or significance to the audience.
One or two proof points — a number, a name, a before/after, a quote.
Audience & channel — LinkedIn, X, Slack, email — and the tone (celebratory, matter-of-fact).
Call to action — what you want people to do next (try it, read more, congratulate the team).
Output Format
Keep it short enough to read in five seconds. Use this structure:
[🎉 emoji] [Punchy headline — the news in one line]
[One sentence: what it is and why it matters.]
[Proof point 1] — a number or concrete fact
[Proof point 2] — another
(optional)[Proof point 3]
👉 [Call to action] — [link or next step]
Then provide:
3 alternate headlines — so they can pick the punchiest.
A one-line caption for the post body (the card is the image; this is the text beside it).
Channel note — any tweak for the chosen channel (hashtags for X, tag-the-team for LinkedIn, etc.).
Quality Checks
Headline states the actual news — not "Exciting update!" but the specific thing
