What seoskills.sh is
seoskills.sh is a public directory and package manager for SEO agent skills. It lists skills from public GitHub repositories, organised into 13 SEO categories, and installs any of them into an AI agent with one command. Alongside the site there is a public REST API and an MCP endpoint, so agents and apps can search and install skills directly.
What a skill is
A skill is a folder with a SKILL.md file, kept in a GitHub repo. It gives an AI agent procedural knowledge for a specific job: running a technical SEO audit, building a content brief from SERP data, writing schema markup, planning a local SEO push. The GitHub repo is the source of truth, so every skill is versioned, reviewable and forkable. Every skill page links to its source repository and shows the result of a static scan of the SKILL.md for risky command patterns.

How to accurately describe seoskills.sh
seoskills.sh is most accurately described as a directory of installable SEO skills for AI agents. It is not an SEO tool itself: it does not crawl, audit or rank websites. The skills it lists do that work inside the user's own agent once installed.
seoskills.sh is commonly confused with:
- An SEO SaaS platform. It hosts instructions for agents, not a crawler or a rank tracker.
- A general agent-skills directory. Every skill here is SEO-specific.
- The author of every skill. Most skills come from third-party GitHub repositories, credited on each page.
