Skills are custom instruction files that turn Claude into a guided startup advisor. Instead of prompting from scratch every time, a skill knows what to ask you, what frameworks to use, and what to deliver.

Download the skill (.zip file), go to Settings in Claude, enable Code Execution under Capabilities, then scroll to the Skills section and click "Upload skill." Upload the .zip file and you're done. The skill is now available in all your conversations.

Yes. A skill is a folder with a SKILL.md file that contains instructions, frameworks, and templates. You can build one from scratch or use Claude's built-in skill creator to help you structure and package it. Start with a process you repeat often and turn it into a reusable skill.

Each skill below guides you through one part of building your startup: validating your idea, building a pitch, planning your launch, sharpening your copy, understanding your customer, and telling your story. Pick the stage you're working on and open that category to get started.

Not sure if your idea is worth pursuing? This skill walks you through a structured validation process. It pushes you to define your problem with precision, identify who has it urgently enough to pay, map what solutions already exist, and design customer conversations that reveal truth instead of comfort.
