Are Claude skills free?

The skills feature itself is part of Claude. Anthropic ships some skills, and open-source skills are free on GitHub. Professionally built skills are usually paid. HuntingHydra publishes 31 skills built for B2B SaaS growth work at $29/month for all of them, or $199 lifetime.

Where do Claude skills work?

In the Claude apps (web, desktop, mobile), in Claude Code, and via the Claude API. In Claude Code they live in a .claude/skills folder. In the Claude apps you enable them in settings under capabilities. The skill format is the same everywhere.

What is the difference between a Claude skill and a prompt?

A prompt is a one-off instruction you paste into a chat. A skill is packaged and persistent: it has metadata that tells Claude when to activate it, structured instructions, and optionally scripts and reference files. Claude loads it automatically when the task matches, so the quality is repeatable instead of depending on how well you prompted that day.

What is the difference between Claude skills and MCP?

MCP (Model Context Protocol) connects Claude to external tools and data sources, like a database or a browser. Skills teach Claude procedures: how to approach a task, in what order, with what output format. They complement each other. MCP gives Claude hands, skills give it a playbook.

Do Claude skills work with ChatGPT or Gemini?

The SKILL.md format is Claude-native, but the instructions inside a well-written skill are plain text. Every HuntingHydra skill is tested in Claude, ChatGPT, and Gemini: paste it as a custom instruction or Gem and it runs the same playbook.

How do I install a Claude skill?

In Claude Code, save the skill folder into .claude/skills in your project or home directory. In the Claude apps, enable skills in settings and upload the skill. From the HuntingHydra marketplace you copy or download any skill and paste or save it in under a minute.

Can Claude write its own skills?

Yes. Anthropic ships a skill-creator skill, and you can ask Claude to draft a SKILL.md from a description of your workflow. The catch is quality: a skill is only as good as the process it encodes. Our guide on building skills covers the format and the common mistakes.

What are the best Claude skills for business use?

For B2B SaaS growth work: ICP research, competitive positioning analysis, SEO page audits, GEO brand visibility audits, cold email sequences, and LinkedIn outreach. Those six cover the highest-leverage tasks founders repeat weekly. Our best-skills roundup compares ours and the strongest open-source options.

Who builds the HuntingHydra Claude skills?

The two founders of HuntingHydra, a founder-run growth studio. Every skill in the marketplace started as an internal tool used in paid client sprints ($5,000 each) before being packaged. Nothing is scraped from prompt lists.

How many Claude skills exist?

Thousands. GitHub hosts large community collections, Anthropic ships official ones, and directories aggregate them. The problem is not supply, it is signal: most are thin wrappers around a one-line prompt. Curated, tested collections matter more than big numbers.

Do I need to know how to code to use Claude skills?

No. Skills are written in plain language. If you can paste text into Claude, you can run a skill. Claude Code users get automatic activation, but the Claude web and desktop apps work without touching a terminal.

Claude skills: 31 you can use today, plus every guide you need

Skills are the biggest change to how Claude works since tool use. This is the hub: a directory of 31 sprint-tested skills for B2B SaaS growth work, where skills run, and the guides that cover everything else, from first install to building your own.

// Last updated July 4, 2026. Written by the founder of HuntingHydra.

What a Claude skill is, in short

A Claude skill is a folder that teaches Claude a procedure: a SKILL.md file with a description of when to fire and the playbook to follow, plus optional scripts and templates. Claude loads it automatically when your request matches, so your best instructions become something you install once instead of retype forever.

Full mechanics (SKILL.md anatomy, progressive disclosure, activation, skills vs prompts vs MCP): what are Claude skills, explained properly. This page is the map: where skills run, the directory, and the guides.

Where skills run

Claude apps (web, desktop, mobile). Enable skills in settings under capabilities. Upload a skill once and it is available in your chats.
Claude Code. Drop a skill folder into .claude/skills in your project or home directory. Claude Code activates it automatically when the task matches. Full walkthrough: Claude Code skills guide.
Claude API. Skills run in the code execution container, so agents you build inherit the same procedures your team uses interactively.
Other models. The format is Claude-native but the content is plain text. Well-written skills run as custom instructions in ChatGPT or Gemini. Every skill below is tested in all three.

Why we publish our skills

HuntingHydra is a founder-run B2B SaaS studio. Clients pay $5,000 per sprint where we fix positioning, SEO, GEO, GTM, copy, and UX. The skills in this directory are the internal tools those sprints run on.

Publishing them is not charity. Founders who run our skills and want deeper work hire the studio. Founders who never hire us still get tools that were validated on real companies instead of assembled from prompt lists. Both outcomes are fine with us.

What makes a skill worth installing

A defined input and a defined output. If the skill cannot say what you get, it is a vibe, not a tool.
A description specific enough for Claude to know when to activate it.
An opinion. Good skills encode judgment: what to look at first, what to ignore, when to stop.
Proof it ran on real work before you installed it.

Questions, answered

Claude skills are folders of instructions, scripts, and reference files that teach Claude how to do a specific task your way. Each skill has a SKILL.md file with a name and description. Claude reads the description, and when your request matches, it loads the full skill and follows it. Think of a skill as a repeatable procedure you install once instead of a prompt you rewrite every time.
