Agent skills marketplaces compared: where to find, vet and install SKILL.md skills

An agent skills marketplace is a catalog of SKILL.md skills you can install into Claude Code, Codex, Cursor, GitHub Copilot and other agents. For most people, skills.sh is the place to start: one command installs a skill into any of 79 agents. Inside Claude Code, use Anthropic's official marketplace. When each skill must be checked first, use Tessl or Skills Directory.

None of them makes a skill safe on its own: a skill can run scripts on your machine, so read it before you install it.

Updated November 2026. Every catalog size, feature and price was read on each marketplace's own site or documentation on November 13, 2026. Sizes are each site's own count; they measure different things.

The short answer, by what you need

Install in one command, any agent

skills.sh. Vercel's open-source CLI, npx skills add owner/repo, installs into Claude Code, Codex, Cursor, Copilot and 75 other agents, and a lockfile pins what you installed.

Search the widest index

SkillsMP. About 4 million SKILL.md files from public GitHub, searchable by category and occupation. It finds; it doesn't install or check.

You work in Claude Code

Anthropic's official marketplace. It's already registered: /plugin install a name, and read the plugin's details pane first.

You work in Codex or Copilot

OpenAI's plugin directory (Plugins tab, or /plugins in Codex CLI) and awesome-copilot, which Copilot CLI and VS Code already know.

Every skill checked before you see it

Skills Directory grades each of its 767,482 skills for free. Tessl adds evals that measure whether a skill helps, plus Snyk security scores.

Paid skills from named experts

Agensi. Free and paid skills, loaded into your agent over MCP, with a money-back guarantee on paid ones.

You run OpenClaw

ClawHub, its own registry. In February 2026 researchers found 341 malicious skills among its 2,857; it now scans every version.

See which skills a team actually uses

Zest, not a marketplace. It records which skills each engineer's sessions load, free for 3 seats.

Nine sources compared, plus Zest

Read on November 13, 2026. "Size" is each source's own number: skills.sh counts skills on its install leaderboard, SkillsMP counts SKILL.md files it indexed (copies included), and the plugin marketplaces count plugins, each of which can hold several skills.

Also checked and left out of the table: agentskill.sh (276,000+ skills with per-skill quality and security scores), MCP Market (379,720 skills, mostly an MCP directory), LobeHub's skills market (a CLI that installs into OpenClaw, Claude Code, Codex and Cursor), AgenticSkills (195 hand-picked skills) and Smithery, which lists MCP servers, not skills. GitHub lists such as VoltAgent's are compared in Awesome agent skills lists.

How to choose a marketplace

  1. Start from your agent. Each agent reads skills from its own folders: Claude Code from .claude/skills, Codex, Cursor and Copilot from .agents/skills among others, OpenClaw from skills/. An installer that knows those paths (skills.sh, Tessl, the agent's own marketplace) saves you from copying folders by hand. How to install agent skills has the paths and commands for each agent.
  2. Decide how much checking you need. An index (SkillsMP) lists what exists. A directory with scanners (skills.sh, Skills Directory, ClawHub) flags known-bad patterns. A reviewed catalog (Anthropic's directory, Tessl's evals, Agensi's verified creators) adds a person or a test. Scans miss things: a skill's instructions can do harm without any code.
  3. Read the popularity signal for what it is. skills.sh ranks by installs counted by its CLI. SkillsMP sorts by the repository's stars, so every skill in a popular repo carries the same number: each OpenClaw skill showed 394,354 stars. Tessl shows measured uplift from evals, the only signal of the three that says whether a skill helps.
  4. Prefer pinned installs. A skill can change after you review it. skills.sh records each skill's commit and a hash of its files; Anthropic's community marketplace pins nearly every entry to a commit; Claude Code's auto-update can replace files you already read.
  5. Check the license and the price. SkillsMP reminds you that public on GitHub doesn't mean free to reuse. Paid skills (Agensi) and paid tiers (Skills Directory Pro, Tessl Team) buy curation, alerts or governance, not access.

What the security studies found

Two audits early in 2026 set the tone. Snyk's ToxicSkills study scanned 3,984 skills from ClawHub and skills.sh on February 5: 13.4% had at least one critical issue, 36.82% had a flaw of some kind, and people confirmed 76 malicious payloads by hand. Koi Security found 341 malicious skills among the 2,857 on ClawHub, 335 of them using fake setup steps to install Atomic Stealer, a macOS info-stealer. ClawHub, skills.sh and others have added scanners since. A scan is a filter, not a guarantee, and Anthropic's docs put it plainly: a plugin "can execute arbitrary code on your machine with your user privileges."

Before installing anything, read the SKILL.md and every file in scripts/, check who publishes it, and pin the version. The full checklist, with a worked review of a real skill, is in Are agent skills safe?

Where Zest fits, and where it doesn't

Zest is made by Winding AI, the company that publishes this site, and it isn't a skills marketplace: there's no catalog, it hosts no skills, and it doesn't vet them. Its plugins record each coding-agent session's models, tokens, skills and MCP tools, and its GitHub App links sessions to the pull requests they led to. For skills, that answers a question most marketplaces don't: of the skills a team installed, which ones do its sessions load, how often, and for whom. Tessl's Enterprise plan and Anthropic's Enterprise Analytics API (for Claude Code) report skill use too.

It fits a team on GitHub that has started installing skills and wants to see which ones stick, before standardizing on a set. Starter is free for 3 seats and includes skills, models and tokens per engineer; Pro is $49 a month for 5 seats and Max $149 for 10, with extra seats at $19.

It doesn't fit if you want to find or vet skills: use the marketplaces above. If you want a private registry, evals and install policies alongside usage, Tessl covers more of that: Team is $100 a month, and policies and analytics come with its Enterprise plan (custom price). Zest is GitHub-only, and it can't stop anyone installing a skill. Sharing skills across a team compares the options.

Questions

Is there an official agent skills marketplace?

Not one for every agent. Each agent maker runs its own: Anthropic's official plugin marketplace is built into Claude Code (530 plugins on claude.com/marketplace on November 13, 2026), OpenAI has one plugin directory for Codex and ChatGPT, and GitHub pre-registers the community awesome-copilot marketplace in Copilot. skills.sh, run by Vercel Labs, is the closest thing to a cross-agent catalog: its CLI installs into 79 agents.

Are agent skills marketplaces free?

Browsing and installing are free on all nine sources here. The costs are elsewhere: the agent itself (Claude Code needs a paid Claude plan, from Pro at $17 a month billed annually, or a Claude Console account), paid skills on Agensi, paid API allowances on SkillsMP, Skills Directory ($4 a skill or Pro at $9 a month) for ZIP downloads and change alerts, and Tessl (Team $100 a month; install policies on Enterprise) for teams.

Are agent skills safe to install?

Not by default. A skill can carry scripts that run with your user permissions, and its instructions can steer the agent. In February 2026 Snyk scanned 3,984 skills from ClawHub and skills.sh and found at least one security flaw in 36.82% of them; Koi Security found 341 malicious skills among 2,857 on ClawHub. Read the SKILL.md and every script before installing; the full checklist is in Are agent skills safe?

Do skills from one marketplace work in other agents?

Usually. A skill is a folder with a SKILL.md file in the open Agent Skills format, which Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenClaw and others read. What differs is the folder each agent reads (.claude/skills, .agents/skills, .cursor/skills, .github/skills) and any tools a skill assumes, such as an OpenClaw command or a Claude-only frontmatter field.

Can you make money selling agent skills?

Some people do. Agensi sells skills priced from $5 to $29 among those on its home page and pays creators 70% of each sale, and MCP Market has a Sell Skills program. Most skills, including Anthropic's, OpenAI's and Vercel's, are free and open source, so a paid skill has to do something a free one doesn't.

What is the difference between a skill and an MCP server?

A skill is instructions (plus optional scripts) that the agent loads when a task matches its description. An MCP server is a running service that gives the agent new tools, such as access to GitHub or a database. Use a skill to teach a procedure and an MCP server to reach a system; plugins in Claude Code, Codex and Cursor often bundle both.

Does Smithery list agent skills?

Not today. Smithery is a directory of MCP servers, now part of Arcade, and its /skills page returned a 404 on November 13, 2026. For skills, use one of the nine sources above.
