This page collects every skill in the directory that covers startups: 17 from 5 publishers, including official skills from Expo. Each one links back to its original GitHub repository, so you always get the author's latest version. They span Mobile, Coding Workflow, Marketing & SEO and Finance & Trading.
Our top pick is Market Sizing Analysis by Seth Hobson, from a repository with 42k GitHub stars. Startup Financial Modeling and Startup Metrics Framework round out the top three. Skills are ranked by the popularity of their source repository, with hand-picked favorites first, and official skills from Expo carry a badge.
Open a skill's page and run its install command in your project folder, for example npx skills add wshobson/agents --skill market-sizing-analysis. You can also download any skill as a ZIP and add it to Claude Code or upload it to the Claude app.
Skills from claude-mem rely on shared scripts and agents, so install them as a Claude Code plugin. Their pages show the two commands.
The install guide walks through every method.
Yes. All 17 skills on this page are open source and free to use, and most are MIT licensed. You need a Claude plan that supports skills, or a coding agent that reads SKILL.md files.
Yes. A skill is a folder with a SKILL.md file, and the same folder works in Claude Code, the Claude desktop and web apps (on paid plans with code execution turned on) and the Claude API. Many also work in other agents that support the Agent Skills format, such as Cursor and OpenAI Codex. Skills that ship scripts need somewhere Claude can run code.
