What are Claude Skills?

A Claude Skill is a folder containing a SKILL.md file of instructions, plus optional scripts and resources, that Claude loads automatically when a task matches it. First-party skills from Anthropic (document creation, frontend design, skill authoring) work the same across Claude.ai, Claude Code and the API. Community agent skills follow the same SKILL.md format and drop into Claude Code, Cursor, Codex and other agents.

What is the difference between a Claude Skill and an MCP server?

A Skill changes how the agent behaves: it is instructions and context the model reads before acting. An MCP (Model Context Protocol) server changes what the agent can reach: it exposes tools and live data, such as a GitHub repo, a Postgres database or a browser, over a standard protocol. You often use both together: an MCP server connects the agent to your database, and a Skill tells it how you want queries written.

What are the best Claude skills to install?

There is no single best set, because it depends on your work. This directory tracks 114 entries across four legs and flags 35 as essential: the first-party document and skill-authoring skills, a handful of coding-discipline agent skills, the core MCP servers (filesystem, GitHub, a database connector, a browser) and one strong prompt or slash-command library. Start there, then add niche skills only when a real task needs one.

How many skills should I install?

Fewer than you think. Every skill, server and command loaded into context spends tokens and attention the agent could use on your task, a real context tax. The working consensus in the ecosystem is that eight to twelve well-chosen skills cover most of a senior developers day; past that, quality often drops rather than rises. Treat the catalog as a menu, not a checklist.

Are community agent skills and MCP servers safe to install?

Treat them like any third-party dependency. A community skill is instructions the model will follow, and an MCP server is code that runs with access to your tools and data, so both can carry prompt-injection or credential-exposure risk. Prefer first-party and well-starred, actively maintained repos, read the SKILL.md or server source before installing, and scope credentials tightly. This directory links every entry to its own primary repo so you can vet it.

How current is this directory?

It is a representative snapshot verified July 25, 2026, with each entry grounded to its own GitHub repo or official docs. The skills and MCP ecosystem moves weekly: new skills ship daily, servers get deprecated, and repos are renamed. Use this as a curated map and confirm each entry at its linked source before you install.

The extension layer of the agent stack, mapped and rated. 114 skills, MCP servers and prompt libraries across four legs, each grounded to its own repo or docs and tagged with whether it is actually worth installing. Built to answer one question the endless auto-generated lists do not: of the thousands out there, which handful earns a place in your agent? For the harnesses these plug into, see AI coding agents; for a deeper cut on connectors, the MCP servers worth installing; and for the primitives themselves, the Claude Code harness guide.

Claude Skills vs agent skills vs MCP vs prompts: what is the difference?

Claude Skills, agent skills, MCP servers and prompt libraries all extend an AI coding agent, but they are different things. A Skill is a folder of instructions the agent loads on demand to follow your standards. An MCP server is a live connector that gives the agent tools and data (a repo, a database, a browser). A prompt or slash-command library is reusable text you paste in. Skills and prompts change how the agent behaves; MCP servers change what it can reach.

The four legs of the agent extension stack

Every entry sits in one of four legs, and the leg usually decides how you adopt and how much you trust it. First-party Claude Skills carry no install risk. Community agent skills and MCP servers run instructions or code you did not write. Prompt libraries are the cheapest to audit because they are just text.

Tier is this site's own read on whether an entry is worth installing today, not a vendor metric. The ecosystem moves fast: new skills ship daily and repos get renamed or archived, so each entry links to its own primary source. Community skills and MCP servers run code or instructions you did not write: read the repo before you install.

How to choose what to install

The mistake is treating skills and servers as free. Every one you load spends context the agent could use on your actual task, so the goal is the smallest set that covers your work, not the longest.

Start first-party. Anthropic's own Claude Skills carry no third-party code and load only when relevant. The document, design and skill-authoring skills cover a lot of ground before you install anything from a stranger.
Add MCP for reach, not behavior. If the agent needs to touch a repo, a database, a browser or a SaaS tool, wire up the matching MCP server. Four or five connectors (filesystem, GitHub, a database, a browser, your issue tracker) cover most real workflows.
Add community agent skills for discipline. The highest-leverage community skills encode coding standards and review habits. Vet the repo first: a skill is instructions your model will follow.
Keep prompts as text you own. Copy a slash-command or prompt library into your project rather than depending on a service, so you can read and edit every line.

To turn any of this into a budget, the cost is the agent's tokens, not the skill: see what a real task actually costs on the cost-per-task calculator, rank models by value on the value leaderboard, or check whether a subscription beats the API with thesubscription vs API calculator.

Why this is a curated snapshot, not a live index

The skills and MCP ecosystem is the most fast-moving layer of the agent stack. New skills ship daily, popular repos get renamed or archived, and auto-updating directories already index tens of thousands of entries. Competing on raw count is pointless and unhelpful. This directory is therefore a representative, opinionated map as of July 25, 2026, built to ground every entry to its own source and answer which ones are worth your context, not to mirror the whole registry. Confirm each entry at its linked source before you install.

Frequently asked questions

What are Claude Skills?: A Claude Skill is a folder containing a SKILL.md file of instructions, plus optional scripts and resources, that Claude loads automatically when a task matches it. First-party skills from Anthropic (document creation, frontend design, skill authoring) work the same across Claude.ai, Claude Code and the API. Community agent skills follow the same SKILL.md format and drop into Claude Code, Cursor, Codex and other agents.
What is the difference between a Claude Skill and an MCP server?: A Skill changes how the agent behaves: it is instructions and context the model reads before acting. An MCP (Model Context Protocol) server changes what the agent can reach: it exposes tools and live data, such as a GitHub repo, a Postgres database or a browser, over a standard protocol. You often use both together: an MCP server connects the agent to your database, and a Skill tells it how you want queries written.
What are the best Claude skills to install?: There is no single best set, because it depends on your work. This directory tracks 114 entries across four legs and flags 35 as essential: the first-party document and skill-authoring skills, a handful of coding-discipline agent skills, the core MCP servers (filesystem, GitHub, a database connector, a browser) and one strong prompt or slash-command library. Start there, then add niche skills only when a real task needs one.
How many skills should I install?: Fewer than you think. Every skill, server and command loaded into context spends tokens and attention the agent could use on your task, a real context tax. The working consensus in the ecosystem is that eight to twelve well-chosen skills cover most of a senior developers day; past that, quality often drops rather than rises. Treat the catalog as a menu, not a checklist.
Are community agent skills and MCP servers safe to install?: Treat them like any third-party dependency. A community skill is instructions the model will follow, and an MCP server is code that runs with access to your tools and data, so both can carry prompt-injection or credential-exposure risk. Prefer first-party and well-starred, actively maintained repos, read the SKILL.md or server source before installing, and scope credentials tightly. This directory links every entry to its own primary repo so you can vet it.
How current is this directory?: It is a representative snapshot verified July 25, 2026, with each entry grounded to its own GitHub repo or official docs. The skills and MCP ecosystem moves weekly: new skills ship daily, servers get deprecated, and repos are renamed. Use this as a curated map and confirm each entry at its linked source before you install.
