Best Claude Code Plugins & Skills (2026)
Looking for the best Claude Code plugins to supercharge your workflow? This guide covers 20 production-ready plugins and agent skills — from engineering and DevOps to marketing, product management, and C-level advisory.
All plugins listed here are open-source (MIT), tested in production, and installable in one command.
What's the Difference Between Plugins and Skills?
Claude Code plugins use the .claude-plugin/plugin.json format and install via /plugin install. Agent skills use SKILL.md files and work across Claude Code, Codex, Gemini CLI, Cursor, and 8 other coding agents.
This repo provides both formats — every skill includes a .claude-plugin directory for native Claude Code plugin support, plus a SKILL.md for cross-platform compatibility.
