# Frequently Asked Questions

Everything you need to know about agent skills, Claude Code, OpenAI Codex, and AI coding tools in 2025

/**

* Agent Skills are modular capabilities that extend AI coding assistants. Each skill consists of a SKILL.md file with instructions, plus optional scripts and templates. In December 2025, Anthropic released the Agent Skills specification as an open standard, and OpenAI adopted the same format for Codex CLI and ChatGPT. Skills are model-invoked—the AI automatically decides when to use them based on context.

*/

/**

* For Claude Code: Add to ~/.claude/skills/ (personal) or .claude/skills/ (project). For OpenAI Codex CLI: Add to ~/.codex/skills/. Both use the same SKILL.md format. Clone the GitHub repository and copy the skill folder to your chosen directory. The AI automatically discovers and loads skills from these locations.

*/

/**

* Skills from this marketplace are sourced from public GitHub repositories. We filter out low-quality repos (minimum 2 stars) and scan for basic quality indicators, but you should always review the code before installing. Community skills should be treated like any open-source code—inspect before use.

*/

/**

* Yes! Claude Code supports multiple skills simultaneously. Skills are modular and designed to work together. For example, you can combine a 'code-reviewer' skill with a 'git-automation' skill to automatically review and commit code changes. Claude intelligently selects the appropriate skills based on your request context.

*/

/**

* Yes! You can create custom Claude skills and share them on GitHub. Check out the skill-creator skill for detailed guidance on creating your own skills. The basic structure requires a SKILL.md file with instructions. You can also add optional scripts, templates, and a marketplace.json for easier distribution.

*/

/**

* Skills are model-invoked—Claude automatically decides when to use them based on context. Slash commands are user-invoked—you explicitly type the command to trigger them. Skills enable more intelligent, context-aware automation in your workflows.

*/

/**

* Our scraper regularly syncs with GitHub to fetch the latest skills and updates. When a skill repository is updated on GitHub, the changes will appear on SkillsMP shortly after our next sync. You can see the last update timestamp on each skill card. We recommend checking back regularly for new skills and improvements to existing ones.

*/

/**

* marketplace.json is a metadata file that enables one-command installation of skills through Claude Code plugin marketplaces. When present, users can install skills with a simple command like '/plugin install skill-name' instead of manually copying files. Skills with marketplace.json are marked with a special badge on SkillsMP. This file contains information about the skill's name, description, version, and installation instructions.

*/

/**

* No, SkillsMP is an independent community project. We aggregate and showcase agent skills from GitHub to make discovery easier. For official skills and documentation, refer to Anthropic's github.com/anthropics/skills or OpenAI's Codex documentation.
