Courier Skills: teach your AI agent to build with Courier

Courier Skills is an agent skill designed to streamline the integration of the Courier notification platform with AI coding assistants like Claude Code, Cursor, and Codex, among others. It provides verified knowledge to help AI agents efficiently handle notification tasks by outlining the correct primitives for various use cases, exact payload shapes, and common mistakes that lead to errors. This tool enables agents to significantly reduce the time spent on integration by providing clear guidance on error resolution, thereby enhancing speed and accuracy. The rebuilt Courier Skills includes 35 reference files covering key areas such as channels, journeys, templates, preferences, and delivery debugging, with a focus on indexing errors and common mistakes to facilitate quick problem-solving. Additionally, the skill can be installed without requiring an API key, and it operates alongside the Courier MCP server, which provides operational capabilities but lacks the detailed payload guidance offered by Courier Skills. The skill is open-source, free, and supports multiple coding environments, ensuring seamless integration across different platforms and enabling teams to install it globally or per project.
