Produce internal Slack announcements for a feature release — tailored messages for CS (activation/retention), Sales (pitching/positioning), Marketing (ads/campaigns), plus a combined update. Use this skill whenever the user says 'internal marketing', 'internal launch', 'write a battlecard', 'CS enablement', 'sales enablement', 'feature announcement for the team', 'prep CS and sales', 'how do we tell the team about this feature', 'write release comms', 'internal marketing for this feature', or when a feature ships and internal teams need to know about it. Also trigger on '/internal-marketing'.
