Claude and Codex Skills: The AI Visibility Wedge I Would Rank First
By Agrici Daniel | May 28, 2026
Claude Code skills, plugins, hooks, agents, AGENTS.md, CLAUDE.md, and Codex skills are now a real search cluster. Here is the source-backed map I would rank for before extracting a new AI visibility skill.
The fastest ranking wedge right now is not a generic AI visibility article. It is the education gap around Claude Code skills, Claude Code plugins, hooks, agents, AGENTS.md, CLAUDE.md, and OpenAI Codex skills. The same-day DataForSEO pack showed strong demand: claude code skills at 9,900 monthly US searches, claude code plugins at 4,400, codex skills at 2,400, and best claude code skills at 320 with KD 1.
What is the difference between skills, plugins, hooks, and agents?
Skills are reusable workflows. OpenAI describes Codex skills as folders with a required SKILL.md plus optional scripts, references, and assets; Codex uses progressive disclosure, so it starts with metadata and loads the full skill only when chosen. Anthropic's Claude Code docs use the same basic idea: a skill teaches Claude how to handle a task and can be invoked directly or when relevant.
| Layer | What it does | Ranking angle |
|---|---|---|
| Skill | Reusable task workflow with instructions and optional scripts/resources. | People search for examples, best skills, install paths, and when to create one. |
| Plugin | Installable distribution package. OpenAI says plugins are the distribution unit for reusable Codex skills and apps. | Users need to know when a skill should stay local and when it should be packaged. |
| Hook | Lifecycle automation around tool use, permissions, or workflow guardrails. | Great for governance, but not the first artifact for a content workflow. |
| Agent | Specialized worker role with focused instructions and tool permissions. | Useful for parallel execution, research, verification, and bounded implementation slices. |
| Memory file | Project or user context such as AGENTS.md for Codex or CLAUDE.md for Claude Code. | Users search for where instructions live and why not everything should become a skill. |
Why not create the AI visibility skill first?
Because a skill is best after the workflow stabilizes. OpenAI's skill guidance says each skill should stay focused on one job and use scripts only when deterministic behavior or external tooling is needed. Right now, the AI visibility loop still has three moving parts: DataForSEO evidence, answer-first content production, and cross-site publishing. If we package too early, the skill will either be vague or overloaded.
The better move is to rank the public method first. Publish the AI visibility tool page, publish the public questions/PAA article, and use this article as the education bridge. After three to five real runs, extract the stable pieces into a dedicated skill.
Where Claude Code and Codex differ
Do not blur the two ecosystems. Codex uses AGENTS.md and Codex skills. Claude Code uses CLAUDE.md for memory and Claude skills/plugins for reusable workflows. If you want to reuse an AGENTS.md idea inside Claude Code, treat it as content to import or translate into CLAUDE.md; do not claim Claude Code reads it directly unless your project wiring explicitly does that.
For Codex, the official docs say skills can live in user, repo, admin, and system locations, and that plugins can bundle skills, apps, MCP server configuration, and presentation assets. That distinction matters for the ranking page: a local workflow belongs in a skill; a shared installation experience belongs in a plugin.
The ranking cluster I would build
- Hub: Claude Code skills vs plugins vs hooks vs agents. This article can serve that intent on agricidaniel.com.
- Commercial spoke: AI visibility tool on claude-seo.md, because tool intent has demand and low-to-moderate KD.
- Method spoke: Public questions and PAA SEO on claude-blog.md, because it explains how content becomes answer surfaces.
- Proof spoke: GitHub READMEs and release notes for claude-seo, claude-blog, and codex-seo.
Official-source checklist
Use these rules when writing or updating the cluster:
- Use OpenAI docs for Codex skills, AGENTS.md, and plugins.
- Use Anthropic docs for Claude Code skills, plugins, commands, and memory.
- Use Google Search Central for AI features, snippets, robots controls, and structured data policy.
- Use DataForSEO docs and same-day API output for SERP, keyword, PAA, and AI visibility measurement.
- Use first-hand repo and vault evidence for your own tool claims.
What this means for the new skill
The future skill should not be named too broadly. I would split it into two focused candidates after repeated runs:
- ai-visibility-loop: accepts brand, competitors, prompts, and URLs; outputs measured gaps, sources, and priority fixes.
- public-questions: accepts a seed keyword; outputs PAA clusters, answer-first blocks, page outline, visible FAQ section, source checklist, and internal-link plan.
Until then, use the existing stack. Claude SEO can research and audit the visibility gap. Claude Blog can turn that gap into source-backed content. agricidaniel.com can publish the ecosystem explanation and point people to the tools. That is enough to rank before turning the SOP into a reusable skill.
