OpenAI Skills API — Hands-On Demo
— OpenAI's Skills API enables models to execute reusable, self-contained scripts and tools by packaging instructions and code (plus optional assets) with a `SKILL.md` manifest. This project demonstrates crafting a custom skill (“csv-insights”), uploading it via the `/v1/skills` endpoint, and invoking it in natural language through the Responses API’s hosted shell environment, where the model installs dependencies, executes scripts, and returns outputs such as markdown reports and plots.
