This tutorial demonstrates how to create a custom Claude Code skill to automate the drafting of overdue invoice reminders. The skill reads invoice data from a markdown file, calculates the days overdue, and generates increasingly firm reminder drafts based on a predefined escalation ladder. To ensure safety, the skill is configured to only draft messages and never send them, with an additional hook to block any attempt to send emails or use other communication methods. AI
