We'll show you how to write just a few lines of code to build new clawhub skills, such as fetching live USD stock prices, and how to validate their functionality seamlessly. **OpenClaw is only as powerful as the skills you give it. Without skills, it has nothing to act on. In this video, I walk you through exactly how to create custom skills from scratch — what the file structure looks like, how the instruction file connects to the actual tool, and how to validate that OpenClaw has picked it up correctly. To make it concrete, I start with a simple stock price lookup skill so you can see the full pattern clearly before applying it to something real.** **The real-world use case is invoice extraction. I've got a folder full of invoices that need to be parsed and structured, and I want OpenClaw to handle all of it autonomously. To do that properly, I bring in Upstage Studio — a document intelligence tool that parses PDFs, runs an extraction workflow, and returns structured JSON through an API. I set up the workflow in Upstage, then show you two ways to add it as a skill in OpenClaw: building it manually, and simply asking the agent to create the skill itself from the API instructions. With one prompt, OpenClaw then processes the entire invoices folder, auto-generates the script, and outputs all extracted data — no manual work required.** **By the end, you'll have a clear mental model of how OpenClaw skills work and how to apply them to any automation task you're dealing with.** **⏱ Timestamps** 0:00 – Why OpenClaw needs skills and what we're building today 1:02 – Installing and configuring OpenClaw for the first time 2:22 – Setting a custom workspace for full visibility and control 3:28 – Creating your first skill manually: stock price example 5:27 – Validating and testing the skill live in chat 6:12 – Real-world use case: batch invoice extraction with Upstage Studio 8:16 – Asking OpenClaw to create a skill automatically 9:06 – One prompt to process an entire folder of invoices *Thanks to Upstage for sponsoring this video.
