Agent skills are reusable capability packs — folders of structured instructions, and sometimes scripts and reference files, that teach an AI coding agent how to do a specific job the same way every time. Install one once and the agent loads it on demand instead of you re-explaining context every session, which keeps its working memory lean. This is the curated, community-ranked index of the best skills for Claude Code, the Claude apps, Cursor, and other agent runtimes.

Best for Auditar una base de código desconocida o legacyThe Agent Skills format was popularized by Anthropic's Claude: a skill is a directory with a SKILL.md file — a name, a short description, and Markdown instructions — optionally bundled with helper scripts and resources. The agent reads only the one-line description until a task matches, then pulls in the full skill. This “progressive disclosure” is what makes skills scale: you can install dozens without bloating the context window, because the model only loads the body of the ones it actually needs.
Skills are portable, composable, and inspectable. The same skill can run across projects and, increasingly, across tools that adopt the format, and several can stack on a single task. Because most are open source and version-controlled, you can read exactly what the agent will be told before you install it. Browse the ranked list below, open any skill for its source and setup steps, and upvote the ones that earn a permanent place in your setup.
An agent skill is a packaged set of instructions — and sometimes scripts and reference files — that teaches an AI coding agent how to perform a specific task reliably. Instead of re-explaining context each session, you install the skill once and the agent carries that knowledge forward whenever a matching task comes up.
A skill is a folder containing a SKILL.md file with a name, a description, and Markdown instructions. The agent keeps only the short description in context and loads the full skill on demand when a task matches — a pattern called progressive disclosure that lets you keep many skills installed without using up the model's context window.
Most skills install by placing the skill folder in your agent's skills directory, adding it through the tool's plugin or extension system, or pointing the agent at the skill's repository. Open any skill below and follow its link for the exact, source-specific steps.
A skill is knowledge: instructions that shape how the agent behaves. An MCP server is a live connection: it gives the agent new tools and data (a database, an API, a filesystem). They're complementary — a skill can tell the agent how and when to use the tools an MCP server exposes.
Claude Code and the Claude apps support the Agent Skills format natively, and because skills are plain Markdown folders, other agent runtimes are adopting the pattern. Each entry notes the tools it's built for.
The majority of skills listed here are open source and free to use. Open an entry and follow its link to confirm the license and any requirements before depending on it.
Yes. Create a folder with a SKILL.md file, write a clear name and description so the agent knows when to use it, then add your instructions and any helper scripts. Many of the skills below are good templates to start from.
