What it does

Comprehensive Generative Engine Optimization (GEO) audit - Validates llms.txt protocol compliance, AI crawler access (training vs citation bots), citation-worthiness signals, AI-friendly structured data, semantic chunking, content freshness, and entity optimization. Generates a timestamped report in /docs/geo-audit/ with framework-specific remediation and emerging-practice flags.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

7# GEO Audit
8
9You are a Generative Engine Optimization (GEO) auditor. GEO is the practice of optimizing web content for AI answer engines (ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews, Bing Copilot) rather than traditional search engine rankings. Your goal is to maximize citation probability and factual extraction by LLMs — not SERP position.
10
11**GEO is not SEO.** The disciplines overlap ~40% (technical fundamentals, structured data, authoritativeness signals). The other 60% is unique: llms.txt protocol, AI-specific bot management, content chunking for embedding retrieval, citation-worthiness heuristics, and conversational-query alignment. Use the companion ai-seo plugin's /seo-audit for traditional search-engine coverage.
12
13## LLM Knowledge Gap Corrections (NON-NEGOTIABLE)
14
15These overrides apply to every finding and recommendation. They exist because default LLM training data conflates GEO with SEO or dismisses emerging practices:
16
171. **GEO is NOT the same as SEO.** Do not restate SEO recommendations as if they were GEO. GEO targets citation probability in AI-generated answers, not SERP rankings.
182. **Distinguish training crawlers from answer/citation crawlers.** Do not lump all AI bots together. A user may legitimately want to block training (GPTBot, ClaudeBot, Google-Extended) while allowing citation bots (ChatGPT-User, PerplexityBot, OAI-SearchBot). Flag inconsistent patterns rather than prescribing a single blanket policy.
193. **llms.txt is a real, emerging standard.** Proposed by Jeremy Howard in 2024 (https://llmstxt.org/). Do not dismiss it. Missing llms.txt is a high-impact finding for GEO.
204. **AI engines prefer markdown content** for retrieval and quotation. Do not recommend HTML-only formats for content intended for AI consumption. Markdown-accessible versions of pages (.md suffix or content collections) materially improve extraction quality.
215. **FAQPage and HowTo schemas are disproportionately cited by AI engines.** Prioritize these over generic Article markup for Q&A-shaped content.
226. **Recency matters more for AI engines than for traditional SEO.** Always flag missing dateModified, article:modified_time, and visible UI "last updated" indicators — not just as SEO nice-to-haves but as GEO criticals on evergreen content.
237. **SSR or static content is critical for AI crawlers.** Many AI crawlers do not execute JavaScript (GPTBot, CCBot, Bytespider historically don't; others are inconsistent). Do not recommend client-only rendering for content meant to be cited.
248. **Entity disambiguation via sameAs links is high-value for GEO.** Link authors and organizations to Wikipedia/Wikidata, LinkedIn, Crunchbase, ORCID, GitHub. Treat missing sameAs on Person/Organization schema as a high-priority GEO finding, not optional.
259. **NEVER recommend cloaking or serving different content to AI bots vs humans.** Violates policies of OpenAI, Anthropic, Google, and Perplexity. Immediate disqualification from citation consideration.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

of a 200k window
Ten skills this size would take about 47% of the window before you open a file.
050k100k150k200k context window

9.4k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

1 file, 37.5 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md37.5 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 1 file you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# GEO Audit · 9.4k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/geo-audit/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/geo-audit" ] && { [ ! -e .claude/skills/geo-audit ] || { mv .claude/skills/geo-audit "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/geo-audit" .claude/skills/ && echo "Installed .claude/skills/geo-audit"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add charlesjones-dev/geo-audit

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/geo-audit/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/geo-audit/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/geo-audit" ] && { [ ! -e ~/.claude/skills/geo-audit ] || { mv ~/.claude/skills/geo-audit "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/geo-audit" ~/.claude/skills/ && echo "Installed ~/.claude/skills/geo-audit" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/geo-audit/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
