61 focused skills.
Two complete kits.

How should you choose a skill?
Start with $seo audit for a full-site analysis across technical SEO, content, schema, performance, and AI readiness. Returns a prioritized action plan.
Pick a focused skill when the problem is already identified — canonical errors, weak E-E-A-T, missing schema, backlink review, or Search Console reporting.
Use $seo drift for regression checks and $seo google for first-party Google metrics. Works on any schedule.
