Paid against free › AI & Automation › AI Assistants & Agents › Agent Skills & Plugins · Coding agents and dev tools on Repo Radar

Reusable skills and plugins add task-specific methods to an agent you already use. Compare catalog discovery, local installation, authoring and version control, then check the chosen runtime and the exact package license. Paid marketplaces add access or commerce; libraries and CLI managers can cover parts of the same job with more responsibility for setup, review and updates.

Lifecycle

Also considered

Looked at, and left out of the comparison, with the reason.

Paid apps

  • Skills.shProvides an open skill directory and installation route. This report includes its CLI repository rather than treating the directory as a separate paid application.Source
  • Agent Skills MarketplaceIndexes public agent skills and points users to their sources. Its directory role overlaps the selected discovery tools, without a paid buyer offer established in this review.Source
  • Cursor DirectoryFocuses on discovering community plugins for Cursor. It is useful within that ecosystem, while the selected paid tools cover broader skill discovery or managed publishing.Source
  • Agent Skills (agentskills.me)Downloads open-source skills for local use. Its advertised $0.1-per-task paid service is a cloud-agent waitlist, so it is not selected as a currently established paid skill-delivery offer.Source
  • SmitheryCenters on MCP service discovery, authentication and sessions. That is adjacent infrastructure rather than the skill-package authoring and distribution workflow compared here.Source
  • LobeHubBuilds and operates agent teammates with memory and multi-agent workflows. Replacing the agent workspace is broader than adding reusable skill packages to an existing agent.Source
  • Salesforce AgentforceSupplies enterprise agents and CRM-oriented actions, including reusable capabilities. Its core purchase is an agent operating environment, rather than a portable skill catalog for existing coding agents.Source

Repositories

  • ComposioHQ/awesome-claude-skillsPrimarily curates links to skills and third-party workflows. The selected libraries and installers offer more direct package delivery, while linked skills retain their own setup and licensing.Source
  • composio-community/awesome-claude-pluginsCurates links to Claude plugins and installation pointers. It helps discovery, but the selected repositories contain directly installable libraries or package-management tooling.Source
  • sno-ai/sno-station-skillsProvides agent coordination, peer review and handoffs as a packaged workflow. Its primary job is running an agent team rather than discovering and managing a general skill collection.Source
  • agentskills/agentskillsDefines the Agent Skills specification and reference material. It is foundational interoperability documentation, rather than a ready skill marketplace, manager or substantive workflow library.Source

Gaps

What the research could not settle from the vendors' own pages.

What vendors don't publish

  • BuySkills does not publish a minimum buyer price or a standard subscription tariff on the inspected page. Creator fees do not establish what a buyer must spend.BuySkills · checked 2026-10-27 · source 1
  • A single whole-repository permissive license cannot describe Anthropic’s collection: sampled general skills use Apache terms, while document skills prohibit several forms of copying and redistribution. Review the exact chosen skill before adopting it.anthropics/skills · checked 2026-10-27 · source 1 · source 2 · source 3
  • SkillKit’s current default branch includes the scanner fix after its latest tagged release. Inclusion in a subsequently distributed npm package was not established in this research.rohitg00/skillkit · checked 2026-10-27 · source 1 · source 2

Where vendor pages disagree

  • Tessl’s FAQ mentions a Business tier while its visible cards list Free, Team and Enterprise. No separate Business price was shown, so it is not treated as a purchasable priced plan.Tessl · checked 2026-10-27 · source 1
