AI Skill Market is the fastest way to add production-ready AI capabilities to Claude Code. Instead of spending hours writing prompts and instructions, you install pre-built skills that work instantly. Think of it as an app store for AI workflows—browse, click install, and immediately upgrade what Claude can do for you.
Proof
4,851 skills, agents, workflows and loops in the catalog. 3 verified creators.
Example
Need Claude to write tests using your team's exact standards? Install the "TDD Master" skill in 60 seconds. Claude immediately knows your testing framework, naming conventions, and coverage requirements—no explanation needed.
Installation takes 60 seconds: Browse our marketplace, find a skill you need, click "Install", and copy the command into your terminal. The skill activates immediately in Claude Code—no configuration, no setup files, no dependencies. It just works.
Proof
60 seconds average installation time. No configuration files or dependencies required.
Example
Visit aiskill.market/browse → Search "git commit" → Click "Commit Message Master" → Copy the install command → Paste in terminal → Open Claude Code → Ask "help me commit these changes" → Claude writes perfect commit messages following conventional commits standard.
No. If you can copy-paste a command into your terminal, you can install skills. Most skills work immediately after installation—just talk to Claude normally and it uses the skill automatically. Technical skills are optional but not required.
Proof
One-command installation for every skill. No configuration or coding knowledge required to use most skills.
Example
Sarah, a product manager, installed "Meeting Notes Summarizer" to help Claude digest her 1-hour meeting transcripts into action items. She copied one command, pasted it in terminal, and now Claude automatically structures her notes with owners, deadlines, and follow-ups.
AI Skill Market is 100% free. Every skill, every install, every feature—completely free. No hidden fees, no premium tiers, no credit card required. We make money when creators who get discovered here sell premium support or custom implementations.
Proof
$0 cost. 4,851 free skills. No credit card ever required.
Example
Download the "API Documentation Generator" skill (worth $500 if custom-built) for free. Install "Code Review Assistant" (saves 10 hours/week) for free. Browse our entire marketplace of production-ready skills without paying a cent.
Click "Submit Skill" in the navigation, fill out the form with your skill details (name, description, GitHub URL), and submit. Our team reviews submissions before they go live. If approved, your skill goes live and developers browsing the marketplace can discover it.
Proof
4,851 skills currently in the marketplace, contributed by 28 creators.
Example
John created a "Python Docstring Generator" skill for his team. He submitted it to our marketplace, it was approved and went live, and developers browsing the marketplace began installing it. He has since received feature requests and feedback from other users.
Skills are reusable capabilities (like "write tests" or "generate docs"). Commands are quick actions you trigger with slash commands (like /commit or /review). Agents are autonomous workflows that complete multi-step tasks (like "research competitor pricing and create comparison table"). All three install the same way and work together seamlessly.
Proof
3 distinct capability types — skills, commands, and agents — across 4,851 total listings. All install the same way.
Example
Install "TDD Master" skill → Claude automatically writes tests for your code. Install "/deploy" command → Type /deploy to trigger deployment checklist. Install "Code Auditor" agent → It autonomously reviews your entire codebase and generates security report.
Yes. Skills are plain-text instructions, not executable packages, so there is nothing to sandbox beyond what Claude Code already does. Each skill listing shows install count, quality score, and verification status so your team can assess a skill before adopting it.
Proof
Every skill page shows a live install count and quality score, so reliability can be assessed before installing.
Example
A platform engineering team is evaluating an "API Contract Validator" skill to catch breaking API changes before deployment. Before adopting it, they check its install count and quality score on the skill page, and review the underlying instructions since skills are plain text.
All skills work with all Claude models (Opus, Sonnet, Haiku) across all versions. Skills adapt automatically to the model you're using—Opus gets more detailed instructions, Haiku gets optimized prompts for speed. You never need to worry about compatibility.
Proof
Works with every current Claude model — Opus, Sonnet, and Haiku. No compatibility configuration needed.
Example
Install "Code Reviewer" skill once. Use it with Opus for deep architectural review of complex systems. Use the same skill with Haiku for fast syntax checks on pull requests. The skill automatically adjusts depth and detail based on your model choice.
You need Claude Code CLI installed (available on Mac, Windows, Linux) and a terminal. That's it. No Python environment, no Node.js, no Docker, no cloud accounts. Skills are pure instructions that Claude reads—they don't execute code on your machine.
Proof
Works on Mac, Windows, Linux. Requires only Claude Code CLI. Zero additional dependencies.
Example
Your colleague runs Windows, you run Mac, your teammate runs Linux. All three install the same "Database Schema Generator" skill with the same one-line command. It works identically on all three systems because skills are just text instructions Claude interprets.
Skills auto-update when creators publish new versions. You can also manually update by running the install command again—it overwrites the old version with the latest. Updates are designed to preserve existing functionality thanks to semantic versioning.
Proof
Automatic updates for all skills. Semantic versioning is used so updates stay backwards compatible.
Example
You installed "Git Workflow Master" v1.2 in January. The creator added GitHub Actions support in v1.5. Next time you open Claude Code, you see "Update available" notification. Click to update, and boom—Claude now helps with GitHub Actions too, without losing any v1.2 capabilities.
Absolutely. Every skill is stored as plain text in ~/.claude/skills/. Open the folder, edit the skill file with any text editor, and save. Your changes take effect immediately in Claude Code. You can customize instructions, add your team's standards, or fork skills entirely.
Proof
Skills are plain text files. Fully editable. Changes apply instantly without reinstallation.
Example
You install "API Documentation Generator" but your company uses a specific doc format. Open ~/.claude/skills/api-doc-generator/skill.md, add your company's template structure, save the file. Next time Claude generates API docs, it uses your custom format automatically.
No limits from AI Skill Market. You can install unlimited skills, use them unlimited times, and keep them forever. The only limit is Claude's standard API rate limits (which are generous and rarely hit for normal use).
Proof
Unlimited skill installs. Unlimited usage. No rate limits imposed by our marketplace.
Example
Install 50 skills today, use each one 100 times, install 50 more tomorrow. No restrictions from AI Skill Market — a developer with dozens of skills installed across several projects hits no marketplace-imposed limit.
Skills are isolated by design—one skill's instructions can't reach into another's. If a skill misbehaves, delete its folder from ~/.claude/skills/ and it's gone, with no effect on your other installed skills.
Proof
Skills are isolated by folder. Deleting one folder removes it instantly with no effect on others.
Example
You install "Experimental Testing Framework" skill and it conflicts with your existing "TDD Master" skill (both try to control test generation). You notice the overlap, delete the experimental one, and continue working—your other installed skills are unaffected.
Once installed, skills work offline. They're stored locally on your machine. However, Claude Code itself requires internet to communicate with Claude's API—so while the skill instructions are available offline, you still need connectivity for Claude to process them.
Proof
Skills are stored locally. No internet needed to read skill files. Claude API access requires an internet connection.
Example
You're on a plane with no WiFi. You can't use Claude Code (requires API connection), but your installed skills remain on your laptop in ~/.claude/skills/. When you land and reconnect, all of your skills work immediately without re-downloading.
Every skill goes through 3-step verification: (1) Automated security scan for malicious patterns, (2) Manual code review by our team, (3) Test installation in isolated environment. Verified skills get a green checkmark badge. Verified status is earned, not automatic — most creators do not have it.
Proof
3-step verification process. 3 of 28 creators are currently verified.
Example
A developer submits "Database Migration Helper" skill. Our automated scan checks for dangerous commands. Our team reviews the code line-by-line for security issues. We test it in a sandbox environment. It passes all checks and gets "Verified" badge. Users see the badge and can factor that into their trust decision.
Yes. Skills never execute code or access your files—they're pure text instructions that Claude reads. Claude Code runs in your terminal with your permissions. Skills can't steal data, modify files without your approval, or send information anywhere. You remain in complete control.
Proof
Skills are text-only (no code execution). Claude requires your approval for file changes. No skill content is transmitted to AI Skill Market servers.
Example
You install "Financial Report Analyzer" skill. It tells Claude how to analyze financial data, but the skill itself can't read your files or upload data. When Claude wants to read a spreadsheet, you see the file path and approve it. The skill never touches your data—only Claude does, with your permission.
Our verification process is designed to catch malicious skills before they reach you. Even so, Claude Code sandboxes all operations and asks your permission before making changes. Skills can't install software, open network connections, or modify files without explicit approval from you.
Proof
Multi-layer design: submission review, Claude Code sandboxing, and a user-approval prompt before any file change or command runs.
Example
A bad actor submits "Productivity Booster" skill that secretly tries to instruct Claude to upload code to external servers. Our review process is designed to flag that kind of instruction before publication. Even if one slipped through, Claude Code still prompts you before it acts on your files or runs commands.
No. Skills can't read environment variables, access credential files, or see API keys. They're isolated from your system's secrets. If a skill needs credentials (like for cloud deployment), Claude Code prompts you to input them—the skill never stores or transmits them.
Proof
Skills cannot access environment variables or credential files directly. Claude Code isolates secrets from skill instructions and prompts you before using them.
Example
You install "AWS Deployment Helper" skill. It tells Claude how to deploy to AWS, but can't read your AWS_SECRET_KEY environment variable. When deployment runs, Claude Code prompts: "This operation requires AWS credentials." You enter them interactively. The skill never sees or stores your keys.
No account is required to browse or install skills, and installing a skill does not send your project data to AI Skill Market. The install happens by copying a command or file from the marketplace to your own machine — our servers never see what you do with it afterward.
Proof
No account required to browse or install. Installing a skill copies it to your machine; it does not transmit your project data to us.
Example
You install "Healthcare Data Processor" skill for HIPAA-relevant work. Installing it does not send your healthcare data to AI Skill Market — the install is a one-way copy from the marketplace to your machine, and everything after that happens locally between you and Claude.
Email security@aiskill.market with details of the skill and the concern. We investigate reports and remove confirmed threats from the marketplace. For responsible disclosure of a genuine vulnerability, contact the same address — your report stays confidential.
Proof
Reports go to security@aiskill.market and are investigated before any skill is removed.
Example
You discover a skill that tries to instruct Claude to access files outside the scope it describes. You email security@aiskill.market with details, including the skill's URL and what you observed. Our team investigates and removes the skill if the concern is confirmed.
