What a skill is
A skill is a folder with a SKILL.md file, kept in a GitHub repository. It gives an AI agent step-by-step knowledge for a specific SEO job, such as running a technical audit, writing a content brief from SERP data, or producing schema markup. Every skill in the directory is backed by a real, public repository, so you can read exactly what it does before you install it.
How it works
Find a skill, then install it into your agent with a single command using the open-source skills CLI, no account and no configuration. You can also open a skill straight into ChatGPT, Claude or Sydekick from its page, or copy its SKILL.md and paste it into any agent. Skills are free to install, and each one keeps the licence of its own repository.
Who runs it
seoskills.sh is a Synup project. Synup is a local marketing software company, and its AI agent, Sydekick, can open skills from the directory directly.
Read it by machine
The whole catalog is available to programs as well as people: a REST API, an MCP endpoint, and an Agent Skills discovery index. See the docs for the endpoints, and /ai-info for a structured overview written for AI assistants.
