SkillsMP: The Open Marketplace That Gives Your AI Coding Assistant Superpowers

Agent skills are the missing piece that transforms your AI coding assistant from a generalist tool into a domain-specific expert perfectly aligned with your exact needs.

Your AI coding assistant is smart — it can write functions, debug errors, and refactor code. But what if it could also generate Terraform configurations following your company’s exact standards, run security audits using industry-specific checklists, or automate your entire git workflow with a single command? That is what SkillsMP enables — a marketplace where domain-specific capabilities transform your AI from a generalist into an expert aligned with your exact needs.

That is what SkillsMP enables. It is an open marketplace with over 200,000 agent skills that plug directly into Claude Code, OpenAI Codex CLI, and ChatGPT — turning your AI assistant from a general-purpose coder into a domain-specific expert.

What Is SkillsMP?

SkillsMP (Skills Marketplace) is a community-driven platform that aggregates agent skills conforming to the open SKILL.md standard. Think of it as an app store, but instead of installing apps on your phone, you install specialized knowledge and capabilities into your AI coding assistant.

Every skill is a simple folder containing a SKILL.md file — a structured markdown document with metadata, instructions, and optional scripts. Once installed, your AI automatically detects and activates the right skill based on what you are asking it to do. No slash commands needed. No manual selection. The AI just knows when a skill applies.

SkillsMP is an independent community project — it is not affiliated with Anthropic or OpenAI, even though it works with their tools. The SKILL.md format itself was released as an open standard by Anthropic in late 2025, and OpenAI adopted the same format for Codex CLI shortly after.

Why Skills Matter More Than You Think

Without skills, your AI assistant works from its general training data. It knows about React, but it does not know your React project conventions. It understands SQL, but not your company’s specific database schema patterns. Skills bridge this gap.

Consider the difference:

Without Skills	With Skills
Generic code generation	Code following your team’s exact style guide
Basic git commands	Automated branching, PR creation, and commit message formatting per your workflow
Generic test writing	Tests using your specific testing framework patterns and coverage requirements
Standard documentation	Docs matching your company’s template and tone

Skills are model-invoked, meaning the AI decides when to use them. This is fundamentally different from traditional plugins or extensions — you do not trigger skills manually. The AI reads the skill metadata, understands the context of your request, and automatically applies the relevant skill. For developers interested in workflow optimization, understanding how automating Git workflows from commit to deploy in minutes can complement your SkillsMP implementation.

The 13 Skill Categories

SkillsMP organizes its massive library into 13 categories, covering virtually every aspect of software development and beyond:

How to Install Skills: A Step-by-Step Guide

Getting started with SkillsMP is straightforward. Here is how to find and install your first skill:

Step 1: Browse or Search

Visit skillsmp.com and use the search bar or category filters. The platform supports semantic search — meaning you can describe what you want in plain language rather than guessing exact keywords.

Step 2: Evaluate Quality

SkillsMP filters out low-quality repositories (minimum 2-star threshold on GitHub) and displays quality indicators. However, since skills can contain executable scripts, always review the code before installing. Check the SKILL.md content, look at the repository, and verify the author.

Step 3: Install

Skills install to different locations depending on scope:

Scope	Claude Code Path	Codex CLI Path
Personal (all projects)	~/.claude/skills/	~/.codex/skills/
Project (this repo only)	.claude/skills/	.codex/skills/

Simply clone the skill repository or download and extract the ZIP into the appropriate directory. The AI automatically discovers and loads skills from these locations — no configuration needed.

Step 4: Use It

There is no step 4. Seriously. Once the skill folder is in place, your AI assistant automatically detects it and applies it when relevant. Ask it to do a code review, and if you have a code-review skill installed, it will follow that skill’s specific instructions.

The SKILL.md Standard Explained

Every skill is built on the SKILL.md format — an open standard that ensures compatibility across AI coding assistants. Here is what a minimal skill looks like:

---
name: code-reviewer
description: Reviews code for bugs, security issues, and style violations
---

# Code Review Skill

When asked to review code, follow these steps:

1. Check for security vulnerabilities (SQL injection, XSS, etc.)
2. Verify error handling is comprehensive
3. Ensure naming conventions match the project style
4. Flag any performance concerns
5. Suggest specific improvements with code examples

Skills follow a design principle called Progressive Disclosure:

1. Frontmatter — The AI reads the name and description to decide if the skill is relevant
2. SKILL.md body — Full instructions loaded only when the skill is selected
3. Helper assets — Scripts, references, and templates loaded only during execution

This keeps things efficient — the AI does not load 200,000 skill instructions into memory. It reads minimal metadata, picks the right skill, then loads details on demand. For enterprises managing complex cloud environments, SkillsMP skills can also encode best practices around EU cloud compliance and hidden features to ensure regulatory adherence.

5 Real-World Use Cases

1. Automated Code Review Pipeline

Install a code-reviewer skill alongside a git-automation skill. When you push code, your AI assistant automatically reviews the changes against your team’s standards, creates detailed review comments, and even suggests fixes — all without manually triggering anything.

2. Infrastructure as Code

DevOps skills for Terraform, Kubernetes, and GitHub Actions let your AI generate infrastructure configurations that follow your organization’s specific patterns. Instead of generic Terraform, you get modules structured exactly how your team expects them.

3. Security Auditing

Testing & Security skills can scan your codebase for OWASP Top 10 vulnerabilities, check dependency versions against known CVE databases, and generate compliance reports. These skills encode security best practices that go far beyond what a general AI would catch.

4. Documentation Generation

Documentation skills produce API docs, README files, and technical specifications that match your company’s exact template and tone. They understand your documentation standards and apply them consistently across every file.

5. Full-Stack Prototyping

Combine multiple skills — a frontend framework skill, a backend API skill, and a database schema skill — to rapidly prototype full-stack applications. Each skill ensures its layer follows established patterns, and they compose together naturally because the AI understands context across all of them. Teams leveraging AI for advanced data work can also explore LLM embedding model migration and production tricks to enhance model performance within their SkillsMP workflows.

The MCP Server: Skills for AI Agents

SkillsMP also provides an MCP (Model Context Protocol) server that enables AI agents to programmatically search, discover, and install skills from the marketplace. This is particularly powerful for autonomous agents that need to acquire new capabilities on the fly.

For example, an AI agent tasked with setting up a new project could:

1. Search SkillsMP for skills matching the project’s tech stack
2. Install relevant skills automatically
3. Use those skills to scaffold the project following best practices

This turns SkillsMP from a static marketplace into a dynamic capability layer that agents can tap into as needed.

Creating and Publishing Your Own Skills

Contributing to SkillsMP is straightforward:

1. Create a GitHub repository with your skill folder containing a SKILL.md file
2. Add a marketplace.json file for marketplace indexing metadata
3. Submit to SkillsMP — the platform will index your skill and make it discoverable

Your skill becomes available to the entire community, and because it follows the open SKILL.md standard, it works across Claude Code, Codex CLI, and ChatGPT automatically.

SkillsMP vs. MCP Servers: What Is the Difference?

This is a common source of confusion. Skills and MCP servers are complementary, not competing:

Aspect	Skills (SKILL.md)	MCP Servers
Purpose	Share knowledge and instructions	Extend functionality with tools
Format	Markdown files with optional scripts	Running server processes
Activation	Automatic (model-invoked)	Tool calls from the AI
Use case	“How to do X following our standards”	“Connect to external service Y”
Infrastructure	No server needed — just files	Requires a running process

Think of skills as knowledge and MCP servers as tools. A skill tells the AI how to write Terraform code for your organization. An MCP server gives the AI the ability to actually run terraform apply. You often want both.
