THL Open: 17 Claude Code Skills for AI GEO Auditing

Tech Horizon Labs’ THL Open is the open layer of how we run GEO and AI-visibility audits: a Claude Code skill suite, two original tools built by THL, and the method document that keeps every audit reproducible and evidence-backed. Everything here is MIT-licensed and designed to slot into Claude Code, Codex, Cursor, Gemini CLI, or any agent that reads SKILL.md. One command installs all 17 skills, including the independent agent-readiness benchmark. The audit-report-kit report generator lives alongside them in tools/.

Only the readiness method and the audit suite are open source. The measurement engine behind Are you found by AI?, including its sampling and regression evaluation set, is not in the repo. The found-by-ai skill calls the hosted free scan; it does not contain it.

Installation

Choose the method that fits your workflow:

npx (Recommended)
Claude Code Plugin
Manual Copy

The fastest path. GitHub is the registry; this repo is the package:

# Install the whole suite
npx skills add techhorizonlabs/thl-open

# Install only the live-measurement skill
npx skills add techhorizonlabs/thl-open --skill found-by-ai

# Preview what's included before installing
npx skills add techhorizonlabs/thl-open --list

Install via the Claude Code marketplace. Run these as two separate commands: paste the first, press Enter, then paste the second:

/plugin marketplace add https://github.com/techhorizonlabs/thl-open

/plugin install thl-open@thl-open

Use the full https:// URL. The short owner/repo form causes some setups to clone via SSH and fail without an SSH key configured.

Clone the repo and copy any individual SKILL.md into your Claude Code project:

# Copy a single skill
cp -R skills/agent-readiness-scan ~/.claude/skills/

# Or copy several at once
cp -R skills/geo-audit skills/geo-crawlers skills/geo-schema ~/.claude/skills/

Then invoke the skills naturally in Claude Code:

run an agent-readiness scan on example.com
do a GEO audit of example.com

What’s Included

The suite is organised into three groups:

THL-Original Tools

These tools are built end-to-end by Tech Horizon Labs:

Skill / Tool	What it does
`found-by-ai`	Connects your agent to the free live scan at areyoufoundbyai.com: whether AI engines name a business when buyers ask, and who they name instead
`agent-readiness-scan`	Turns the Cloudflare `isitagentready.com` check into audit-grade CSV artefacts with a tracked 0 to 100 score
`audit-report-kit`	TypeScript/Node tool (in `tools/`, not a skill) that generates a branded client PDF and compile-checked JSON-LD from any GEO audit’s data

GEO Audit Skills (15 skills)

An attributed fork of geo-seo-claude by Zubair Trabzada (MIT), improved and wired into the THL method:

Skill	What it does
`geo`	Umbrella dispatcher: routes `/geo audit`, `/geo citability`, `/geo schema`, and all other `/geo` commands
`geo-audit`	Orchestrates 5 parallel subagents across 6 GEO dimensions and produces thl-open’s own composite GEO Score (not the Are you found by AI? Readiness score)
`geo-citability`	Passage-level AI citation readiness scoring
`geo-crawlers`	AI crawler access and `robots.txt` analysis
`geo-llmstxt`	Analyses or generates an `llms.txt` file
`geo-brand-mentions`	Scans brand presence across AI-cited platforms (Reddit, YouTube, Wikipedia, LinkedIn)
`geo-platform-optimizer`	Platform-specific readiness for Google AI Overviews, ChatGPT, Perplexity, Gemini, Bing Copilot
`geo-schema`	Structured-data detection, validation, and generation
`geo-technical`	Technical SEO foundations: SSR, Core Web Vitals, crawlability, mobile, security
`geo-content`	Content quality and E-E-A-T assessment
`geo-report`	Client-ready markdown deliverable generation
`geo-report-pdf`	Professional PDF report with charts and scores
`geo-compare`	Monthly delta tracking: show score improvements over time
`geo-prospect`	CRM-lite prospect and client pipeline management
`geo-proposal`	Auto-generate client proposals from audit data

Report Toolkit

Tool	What it does
`audit-report-kit`	TypeScript/Node: generates a branded PDF (`@react-pdf/renderer`) and compile-checked JSON-LD (`schema-dts`) from audit data

The geo-* skills are an attributed fork of geo-seo-claude by Zubair Trabzada (MIT). Tech Horizon Labs de-rotted them, fixed portability, and wired them into the THL method, but the foundation is his open-source work, and we credit it fully.

There is no telemetry. Nothing in this repo phones home. Read SECURITY.md in the repo for details.
