What it is

Lets you build coding agents using AI from OpenAI.

Real use case example

"A solo developer wants to automate a task: whenever a new customer signs up on Stripe, they want to add the customer to their Notion database and send a welcome email through Resend. They can create a coding agent using this skill that connects Stripe to Notion and Resend, saving time and making their workflow more efficient."
