What is the Claude SEO skill by Agrici Daniel?

Claude SEO is an open-source Claude Code skill for technical SEO, on-page analysis, structured data, content quality, performance-related signals, and generative-engine (GEO) style checks. It is maintained by Agrici Daniel and contributors, and published under the MIT License.

This article explains what that project is, what license terms imply, and how it differs from ClaudeSkillSEO.com—a separate web platform that uses the skill but is not created by Agrici Daniel.

For the product overview, start with What is ClaudeSkillSEO?.

What the Claude SEO skill provides

In Claude Code, the skill exposes slash commands such as:

• Full-site style audits (/seo audit)
• Single-page analysis (/seo page)
• Schema validation and generation workflows
• Sitemap analysis
• GEO / AI Overviews oriented audits (/seo geo)

The skill’s documentation and SKILL.md define how Claude should crawl, delegate parallel sub-agents, write Markdown reports, and save files under predictable folders (commonly workspace-files/).

Because it is open source, teams can:

• Inspect prompts and structure
• Fork and customize for internal standards
• Run locally on their own hardware with their own Claude access

MIT license in practice

The MIT License is permissive. You may use, copy, modify, merge, publish, distribute, sublicense, and sell copies, subject to including the copyright notice and license text in distributions.

For ClaudeSkillSEO.com:

• We attribute Agrici Daniel and contributors for the skill component
• We do not claim the MIT-licensed skill’s authorship for the web product itself
• Customer-facing reports may contain model-generated analysis; skill code and prompts remain governed by upstream license when redistributed as software

If you ship a fork of Claude SEO internally, keep license files intact and document your changes.

ClaudeSkillSEO.com should not be presented as created by Agrici Daniel. Correct wording: “uses the open-source Claude SEO skill by Agrici Daniel (MIT).”

We do not state or imply that Agrici Daniel endorses this website unless he publicly says so.

How the skill behaves in headless automation

When integrated into a host (including ClaudeSkillSEO), the skill is usually invoked with:

• A explicit run folder (workspace-files/<uid>/<run-id>/)
• Rules to avoid saving deliverables only under ~/.claude/projects/
• Instructions to finish all sub-agents before exiting

That behavior matters for reliable History and downloads in a web product. The skill was originally designed for interactive Claude Code users; hosts adapt it with extra environment rules.

FAQ

Is Claude SEO free?

The skill source is MIT licensed (free to use as software). Running it still requires Claude inference (API or subscription costs) and your own compute if self-hosted. ClaudeSkillSEO adds its own credit model for hosted runs.

Can I contribute to Claude SEO?

Contributions follow the upstream repository’s contribution guidelines on GitHub. ClaudeSkillSEO may track upstream releases separately from its own app roadmap.

Does ClaudeSkillSEO modify the skill?

Hosted environments may add deployment rules (output paths, headless constraints, symlinks for workspace-files). Functional changes should be understood as platform integration, not as replacements for the upstream project unless contributed back.

Where is the license file?

In the Claude SEO GitHub repository. This site’s third-party notices also reference MIT attribution for Claude SEO.
