/shipstar:add-announcement-banner has your coding agent put a one-line announcement bar at the top of your site: the most impactful change of the period as a headline, one sentence, and a call-to-action, generated from your commits. Exactly one banner is live per project — every publish replaces it under the same embed key, so the site is set up once and stays current.

​
Install

Via the official Claude Code plugin (bundles the MCP connection):
Or install the skills standalone from your dashboard’s Agents page (curl -fsSL <APP_URL>/agent-skills/install.sh | sh -s -- <APP_URL>).

​
When to use it

Say “add a what’s-new bar to our homepage”, “highlight the new feature at the top of the site this week”, or “put an announcement banner on our site that updates itself”.

​
What the agent does

  1. Checks the starting point — get_project_context for a connected GitHub source, get_banner for what is live now, and asks where the banner should click through to and whether it should come down on its own.
  2. Generates and reviews — generate_banner (25 credits), then shows you the exact headline, body, and button label before anything goes live; edits go through update_content.
  3. Publishes on your say-so — publish_content makes it the live banner and reports the embed key.
  4. Puts it on the site — the one-tag embed (data-type="banner", sticks to the top, dismissable) or a server-rendered bar from GET /api/v1/banner, where a 404 means “no banner, render nothing”.
  5. Keeps it fresh — points you at the dashboard’s weekly or monthly banner schedule, whose “Link to” and “Take down after” choices apply to every run.

Guardrails

  • Never publishes without you seeing the exact text first.
  • Never invents a link: with no URL from you, Shipstar resolves one at publish (your Changelog page, else the period’s changelog) or shows no button.
