What are Infrasity Claude Skills?

Infrasity Claude Skills are open-source slash commands for Claude Code that automate developer GTM workflows, including documentation audits, SEO analysis, AI discoverability checks, and content briefs, directly from your terminal with no dashboards or API keys required.

What is Claude Code and do I need it to use these skills?

Claude Code is Anthropic's CLI tool that lets you run AI-powered commands in your terminal. You need Claude Code installed to use Infrasity's skills. Most skills require no additional setup beyond that.

What developer GTM tasks can Claude Skills automate?

Current skills cover developer documentation auditing (33 checks), API docs quality scoring, SDK docs review, SEO growth reports, orphan and no-outlinks page audits, LLMS.txt AI readiness checks, blog post counting, and SEO content brief generation.

What is an LLMS.txt file and why does it matter for AI discoverability?

An llms.txt file tells AI systems like ChatGPT, Claude, and Perplexity how to read and cite your documentation. The LLMS.txt Checker skill audits whether your domain has one, whether it's structured correctly, and gives you prioritized fixes if it's missing or incomplete.

How do I check if my documentation is optimized for AI search engines?

Run /dev-gtm docs-audit inside Claude Code. The Docs Auditor checks 33 signals including AI/LLM discoverability, content structure, internal linking, and technical SEO, scoring your docs from 0 to 100.

What is GEO and how do these skills help?

GEO (Generative Engine Optimization) is the practice of optimizing content so it gets cited and recommended by AI systems like ChatGPT, Perplexity, and Claude. These skills audit the exact signals, including structured content, llms.txt, internal linking, and documentation completeness, that AI crawlers use when deciding what to surface.

Do I need an Ahrefs account to use these skills?

Most skills work with no external API keys. The No Outlinks Audit and Orphan Pages Audit skills require an Ahrefs API key to enrich results with traffic data and ranking signals.

How is this different from a standard SEO audit?

Traditional SEO tools optimize for Google crawlers. These skills are built specifically for developer documentation and AI discoverability, checking whether your docs can be parsed, cited, and recommended by LLMs, not just indexed by search engines.

Are the Claude Skills free and open-source?

Yes. All skills are fully open-source and available on GitHub at github.com/Infrasity-Labs/dev-gtm-claude-skills. No license fees, no paywalls.

How often does Infrasity release new Claude Skills?

New skills ship every week. You can watch or star the GitHub repo to get notified of new releases.

Can I request or contribute a skill?

Yes. The repo is open for contributions and issues. If you have a developer GTM workflow you want automated, open an issue on GitHub or reach out to the Infrasity team directly.

What companies are these skills built for?

They are built for DevTool startups, AI agent platforms, observability companies, and any B2B SaaS product with a technical audience, especially teams that want their documentation to be found and cited by AI systems.

What are Claude Skills for writing?

Claude Skills for writing are open-source slash commands for Claude Code that turn blog and content workflows into one-command tasks. The pack covers writing, rewriting, outlines, briefs, SEO and AI-citation optimization, schema, charts, images, translation, and repurposing, all run inside Claude Code with no dashboards.

What is Claude Code and do I need it to use these writing skills?

Claude Code is Anthropic's CLI tool for running AI-powered commands in your terminal. You need Claude Code installed to use these writing skills. Once the repo is cloned into your project, you run any skill through the blog engine, like /blog write or /blog rewrite.

Are these writing Claude skills free and open source?

Yes. Every writing skill is open source and free to use, hosted on GitHub and updated weekly. You can read each skill's prompt, fork it, and adapt it to your own brand voice, audience, and content workflow.

What writing tasks can Claude skills automate?

The full content lifecycle: writing new blog articles, rewriting and optimizing old ones, outlines and content briefs, editorial calendars and topic clusters, on-page SEO and AI-citation (GEO) audits, schema markup, fact-checking, charts and images, audio narration, translation and localization, and repurposing to social, email, and video.

What is AI SEO and GEO, and how do these writing skills help?

AI SEO, also called GEO (generative engine optimization), is getting your content cited in AI answers from ChatGPT, Perplexity, Google AI Overviews, Claude, and Gemini. Skills like blog-geo, blog-schema, and blog-rewrite audit and optimize structure, citation capsules, and answer-first formatting so AI systems can extract and cite your posts.

How do I install and run a writing skill?

Clone the repo, open Claude Code, and run a skill by name, for example /blog write to draft an article, /blog rewrite to optimize an existing post, or /blog repurpose to turn one post into social content. Most skills need no setup beyond Claude Code.

Do these skills make AI writing sound human?

Yes. The stop-slop skill and the AI-content detection in blog-analyze and blog-rewrite catch predictable AI tells like filler phrases, em dashes, and formulaic structure, then rewrite for varied rhythm and a natural voice, with persona controls that keep your brand tone consistent across posts.

Do Claude writing skills replace writers or a content agency?

No. They handle the repeatable, research-heavy parts of content, outlines, sourcing, SEO checks, schema, and formatting, so writers can focus on ideas, voice, and judgment. The skills work best as an extension of your team, not a replacement for it.

Do I need API keys or paid tools to use the writing skills?

Most writing skills run on Claude Code alone. A few that pull live data, like blog-google for Search Console and Core Web Vitals or blog-cannibalization for SERP data, can connect to free or paid APIs when you want richer signals, and each skill notes exactly what it needs.

How are these different from using ChatGPT to write blog posts?

Each skill is a focused expert workflow, not a blank prompt. Instead of re-describing how to write, optimize, translate, or repurpose a post every time, you run one command and the skill follows a proven, repeatable process built for that task, dual-optimized for Google rankings and AI citations.

Blog Cannibalization: find posts quietly competing for the same search intent

Detects keyword cannibalization across your blog by extracting primary keywords, clustering semantically similar targets, and flagging posts competing for the same search intent with a severity-scored report.

>/blog

VIEW ON GITHUB HOW IT WORKS

What the Blog Cannibalization skill actually is?

Find competing pages before they split your rankings

The Blog Cannibalization skill detects when multiple posts on your site compete for the same search keywords, splitting authority that should sit on one page. It extracts primary keywords from titles and headings, clusters semantically similar targets, and flags the pages that overlap.

It runs in two modes. Local mode is the default, free, and needs no API keys: it analyzes file content with Glob, Grep, and Read. API mode, enabled with the --api flag, uses DataForSEO's Page Intersection and Ranked Keywords endpoints at roughly one cent per call to layer in real SERP positions, search volume, and CPC.

Every flagged cluster gets a severity level, Critical, High, Medium, or Low, and one of four recommendations: MERGE, DIFFERENTIATE, CANONICAL, or NO ACTION. The output is a summary table plus per-cluster detail explaining which post is stronger and exactly what to do about the overlap.

When it Triggers?

Invoke it with phrases like "cannibalization", "keyword overlap", "competing pages", "duplicate keywords", or "cannibalize". It accepts an optional target directory and an optional --api flag, defaulting to local analysis of Markdown, MDX, and HTML files while skipping node_modules, .git, and drafts.

Use it when several posts seem to target the same topic, when rankings for a keyword keep flip-flopping between two URLs, or as a periodic audit before publishing more content in a crowded pillar. If you pass --api without DataForSEO credentials configured, it falls back to local mode automatically and tells you.

What it delivers

From keyword extraction to a fix for every cluster

Keyword extraction and clustering

Tokenizes titles and H1s into 1, 2, and 3-gram phrases, scores them across headings and the first paragraph, and groups posts by exact match, stem match, semantic overlap, or subset match into intent clusters.

Two analysis modes

Runs free local analysis via file content by default, or layers DataForSEO Page Intersection and Ranked Keywords data, real positions, volume, and CPC, at about one cent per call when you add the --api flag.

Severity scoring

Assigns Critical, High, Medium, or Low to each cluster. API mode uses an overlap-count, search-volume, and position-gap formula, while local mode uses a heuristic keyed to exact, stem, semantic, and subset matches.

Four recommended actions

Returns MERGE for thin duplicate intents with a 301 redirect, DIFFERENTIATE to retarget the weaker post, CANONICAL to point a duplicate at the authority page, or NO ACTION with documented reasoning when intents genuinely differ.

Up and Running in 3 Steps

No dashboard, no config files, no API keys. Clone the repo, open Claude Code, and the skill is live.

Frequently Asked Questions

Everything you need to know about installing and running these Claude Skills.

It is when two or more of your own posts target the same keyword or search intent, so they compete against each other in search results. That splits authority, link equity, and click-through between pages instead of concentrating it on one, often pushing both down the rankings.

Local mode is the default, free, and needs no keys: it extracts and clusters keywords from your file content with Glob, Grep, and Read. API mode, enabled with --api, calls DataForSEO Page Intersection and Ranked Keywords at about one cent per call to add real SERP positions, search volume, and CPC.

It extracts a primary keyword from each post by scoring 1 to 3-gram phrases across the title, H1, H2s, and first paragraph, then clusters posts using four rules in priority order: exact match, stem match, semantic overlap, and subset match.

Critical means the same exact keyword with both pages in the top 20, High means the same cluster where one page outranks the other, Medium means related keywords with partial SERP overlap, and Low means surface-level similarity but genuinely different intents that you only need to monitor.

Four. MERGE combines thin duplicate posts and 301-redirects the weaker URL, DIFFERENTIATE retargets the weaker post to a long-tail and updates its title and meta, CANONICAL points the duplicate at the authority page, and NO ACTION documents why two similar-looking posts actually serve different intents.

It falls back to local mode automatically and notifies you, so the audit still runs. It also handles other edge cases gracefully: it retries once on a rate limit, skips unreachable URLs, and reports clearly if a directory has no blog files or only a single post.
