    Best for Data Scientists

How it works

Users interact with the marketplace via a command-line interface simulation. They can browse skills organized into 12 categories (e.g., Development, Data & AI), use the AI search function (`search --ai`) to find specific skills, or use filters to narrow results (e.g., sort by `stars` or filter for skills with `marketplace.json`). Once a skill is found, the user installs it by cloning the GitHub repository and copying the skill folder to the appropriate directory (e.g., `~/.claude/skills/` for Claude Code).

How to use Agent Skills Marketplace (SkillsMP)?
Users interact with the marketplace via a command-line interface simulation. They can browse skills organized into 12 categories (e.g., Development, Data & AI), use the AI search function (`search --ai`) to find specific skills, or use filters to narrow results (e.g., sort by `stars` or filter for skills with `marketplace.json`). Once a skill is found, the user installs it by cloning the GitHub repository and copying the skill folder to the appropriate directory (e.g., `~/.claude/skills/` for Claude Code).
What are Agent Skills?
Agent Skills are modular capabilities that extend AI coding assistants. Each skill includes a SKILL.md file with instructions, plus optional scripts and templates. They are model-invoked, meaning the AI automatically decides when to use them based on context.
How do I install an agent skill?
For Claude Code, add the skill folder to ~/.claude/skills/ or .claude/skills/. For OpenAI Codex CLI, add it to ~/.codex/skills/. The AI automatically discovers and loads skills from these locations.
Are skills from this marketplace safe to use?
Skills are sourced from public GitHub repositories, filtered for basic quality (minimum 2 stars). However, users should always treat them like open-source code and inspect the content before installation.
How do skills differ from slash commands?
Skills are model-invoked, meaning the AI intelligently decides when to use them based on context. Slash commands are user-invoked, requiring the user to explicitly type the command to trigger them.
