Claude Code Plugins Plus

claude-code-plugins-plus-skills by Jeremy Longshore is a massive plugin marketplace for Claude Code: 270+ plugins bundling 739 agent skills across productivity, devops, AI/ML, and community categories. What distinguishes it from loose skill collections is the engineering rigor — every plugin is published as a versioned npm package under the @intentsolutionsio scope, with CI validation of SKILL.md files, a schema-gated agent authoring pipeline, nightly roster checks, and a 'Killer Skill of the Week' curation program. Install via the Claude Code plugin marketplace or pnpm.

Scale is both the strength and the risk: 739 skills means real discovery and overlap problems, and quality varies across community-contributed plugins. The npm-per-plugin model is unusual for skills and adds dependency-management surface. Still, for teams that want a governed, versioned skill supply chain rather than copy-pasted markdown, it is the most infrastructure-serious option in the ecosystem.

Add the marketplace in Claude Code: /plugin marketplace add jeremylongshore/claude-code-plugins-plus-skills, then /plugin install <plugin-name>@marketplace. Individual plugins also installable via pnpm as @intentsolutionsio packages.
