Skillselion

Skillselion is an independent, automatically updated directory built for developers who ship with AI coding agents. It indexes over 84,000 agent skills, 7,800+ MCP servers, and 12,100+ plugin marketplaces for Claude Code, Codex, Cursor, and other coding agents — all ranked by real install counts and GitHub stars rather than editorial opinion or vendor promotion. The site is not affiliated with Anthropic, OpenAI, or Cursor.

What It Is

Skillselion is a tool-discovery directory purpose-built for the AI-coding agent ecosystem. As the site describes it, skills, MCP servers, plugins, and marketplaces appear daily across repos, gists, and threads, and Skillselion exists to surface what is actually used without requiring developers to wade through noise. Listings are automatically updated and ranked by adoption — installs first, then GitHub stars — across Anthropic, OpenAI, and Cursor tooling. The directory self-describes as "the #1 directory of Claude Code, Codex & Cursor Skills, Marketplaces & MCP servers."

What the Directory Covers

Skillselion organizes its index into four primary content types:

• Agent Skills — reusable instructions that teach a coding agent specific tasks, installable with a single command. The site indexes 65,800+ skills as of its last update.
• Plugin Marketplaces — curated GitHub repositories containing collections of plugins and tools for AI agents (12,100+ marketplaces indexed).
• MCP Servers — tools, APIs, and integrations delivered via the Model Context Protocol (7,800+ servers indexed).
• Workflows — multi-step pipelines for Claude Code, Codex, Cursor, and other coding agents.

Content is organized by nine categories (AI & Agents, Frontend & Design, Backend & Data, Dev Tools, Automation, Testing & Review, Security, Monitoring & Cloud, Docs & Planning) and by journey phase (Idea, Validate, Build, Ship, Launch, Grow, Operate).

Editorial and Discovery Features

Beyond raw listings, Skillselion publishes several editorial layers to help developers find what is worth installing:

• Trending in search and Hot skills (24h) surfaces breakout tools with install velocity signals.
• Skill of the Day / Week / Month and MCP Server of the Week / Month are hand-picked editorial spotlights refreshed on a rolling schedule.
• Weekly Brief — a Monday newsletter covering Claude Code, Codex, and Cursor releases, model launches, and developer tactics. Recent issues have covered Claude Code CLI releases, Codex Remote reaching general availability, and Cursor's acquisition of Continue.
• Learn section — a curated feed of videos and articles on building with AI coding tools, covering topics like loop engineering, dynamic workflows, and agentic coding patterns.

Ranking and Trust Signals

The site's stated philosophy is "real adoption over hype, honesty over noise." Rankings are driven by install counts (described as 107M+ real installs tracked across the index) and GitHub stars. Some listings surface third-party security signals from public Socket, Snyk, or skills.sh scans, though the site is explicit that these are pass-through signals it does not run itself and are not safety guarantees. No account is required to browse, search, or read the weekly brief.

Current Status
