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 Calendar: editorial planning that keeps content fresh

Generates editorial calendars with topic clusters, publishing cadence, content decay detection, and freshness update schedules. Optimized for building topical authority on Google and maintaining the 30-day citation freshness that AI platforms favor.

>/blog

VIEW ON GITHUB HOW IT WORKS

What the Blog Calendar skill actually is?

An editorial planner that schedules new content, refreshes, and distribution together

The Blog Calendar skill turns a strategy into a dated publishing plan. It scans your existing posts, designs 3 to 5 topic clusters, applies a content mix formula, and outputs a week-by-week monthly calendar or a month-by-month quarterly plan with templates, target keywords, and clusters assigned to every entry.

It enforces a 60% new, 30% freshness updates, 10% repurposed content mix, scaled to your cadence. At 2 posts per week that means 8 monthly posts: 5 new, 2 refreshes, and 1 repurposed. Within new posts it targets content-type diversity across guides, comparisons, listicles, case studies, and thought leadership.

Freshness is central because 76% of top AI citations come from content updated within the last 30 days. The calendar includes a content decay report, a freshness update queue, topic cluster progress tracking, and distribution timing per channel, so the plan covers production and promotion in one artifact.

When it Triggers?

The skill activates on phrases like "editorial calendar", "content calendar", "blog calendar", "publishing schedule", "blog plan", "content plan", or "what should I write". The niche argument is optional, since the skill can scan an existing project for context.

It operates at the FLOW Find stage, so it recommends running /blog flow find first for keyword discovery, content prioritization, and audience avatar prompts that inform cluster selection and topic sequencing before the calendar is built.

What the calendar plans

From decay detection to channel-by-channel distribution timing

Content decay detection

Scans lastUpdated and date frontmatter and classifies posts by staleness using traffic-tiered thresholds. High-traffic posts stale beyond 30 days are flagged Critical for immediate refresh, with a decay report ranking everything by priority.

Content mix formula

Applies the 60/30/10 new-refresh-repurpose ratio scaled to your cadence, then balances new posts across content types: 30 to 40% guides, 15 to 20% comparisons, 15 to 20% listicles, and 10 to 15% each for data research and thought leadership.

Cluster progress tracking

Tracks the build-out state of every cluster and prioritizes finishing partially-built ones. Clusters at 50%+ coverage rank highest, new clusters only start once existing ones hit 75%, and never more than 3 clusters build out at once.

Distribution and freshness scheduling

Plans per-post distribution timing (LinkedIn same day, Reddit at 2 to 3 days, weekly email batches, YouTube for pillars only) and a rolling 30-day freshness schedule that lists posts by next refresh date and suggests /blog rewrite for each cycle.

Frequently Asked Questions

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

Yes. The monthly format breaks down week by week with day, type, title, template, cluster, target keyword, and status columns, plus a content mix summary, freshness queue, and seasonal hooks. The quarterly format plans three months with a focus theme each and quarterly goals for new posts, refreshes, and cluster completion.

It uses a 60% new, 30% freshness updates, 10% repurposed ratio scaled to your publishing cadence. At 2 posts per week you get 8 monthly posts (5 new, 2 refreshes, 1 repurposed). New posts are then spread across guides, comparisons, listicles, case studies, and thought leadership for diversity.

The skill scans frontmatter dates and classifies each post by staleness against traffic-tiered thresholds: high-traffic posts go stale after 30 days, medium after 90, low after 180. It outputs a decay report with priority levels from Critical down to Low, so you always know what to refresh first.

Because 76% of top AI citations come from content updated within the last 30 days. The calendar schedules update cycles by priority and tracks each post's next refresh date, so freshness maintenance becomes a routine rather than a scramble.

Yes. For each new post it schedules channel timing: LinkedIn the same day, Reddit 2 to 3 days later as a genuine insight rather than a link drop, email newsletters batched weekly, and YouTube companion videos for pillar posts only.

It designs 3 to 5 clusters of a pillar page plus supporting posts, then tracks each cluster's coverage percentage. It prioritizes completing clusters already at 50%+ over starting new ones, never starts a new cluster until existing ones reach 75% coverage, and keeps at most 3 clusters in active build-out.
