Your agent starts a session. SkillGild checks your access and allowance, counts one run, and sends the skill's instructions for this task.
Your agent does the work with its own model and tools, in your project. SkillGild makes no AI model call.

Questions
How do I install Claude SEO in Claude Code?
Run skillgild install claude-seo --agent claude-code and connect the SkillGild MCP server (skillgild mcp). When a task matches, your agent starts a session, which uses one of your 25 free runs this month, and follows the skill's instructions. Use --agent codex, cursor or gemini-cli for other clients.
Is Claude SEO free?
Yes. It includes 25 free runs every month on SkillGild. Claude SEO is open source (MIT) by Agrici Daniel; SkillGild packages it from https://github.com/AgriciDaniel/claude-seo at a pinned commit and credits the author.
Does Claude SEO run on SkillGild?
It runs in your coding agent with your own model. SkillGild checks your monthly allowance and delivers the skill's instructions for each session; it makes no model call and never sees your project unless your agent sends it.
Which agents does Claude SEO work with?
The project lists Claude Code. It is a plain Agent Skills folder (SKILL.md plus supporting files), so any client that reads that format can load it.
