The lesson
Open a launch post with the buyer's four requirements, then show your product meeting each, before announcing the new feature.
After a short intro, a bold list of customer-sourced qualities: "Made for the whole team", "Agent-neutral", "Collaborative", "Observable and governable". Then a product screenshot and a large quote from Nima Gardideh, CEO. Only after that does it introduce "the Notion Skills API", with sections on syncing to GitHub and installing through the Vercel CLI.
Don't copy the Skills API or the four qualities. Keep the sequence: the buyer's criteria first, product against criteria second, then an action a technical reader can take today.
