Claude Code’s open-source plugin bazaar

What it does

Tons of Skills is an open-source marketplace and catalog for Claude Code extensions. It aggregates plugins, skills, and agents—covering everything from DevOps automation to mobile testing—into a browsable index at tonsofskills.com. The ccpi CLI handles search and installation, while the repository itself acts as a validated registry with auto-generated category listings.

The interesting bit

The project treats its README like a living dashboard: live npm download stats refresh daily via GitHub Actions, and a “Killer Skill of the Week” spotlight rotates featured integrations automatically. It is essentially a curation layer trying to impose order on an otherwise scattered ecosystem.

Key highlights

• Hundreds of curated plugins across 19 categories, from SaaS packs to AI/ML tooling
• ccpi CLI for discovery and installation alongside integration with Claude’s native marketplace
• Validated community contributions with automated README sections for stats, spotlights, and table of contents
• Packages published under the @intentsolutionsio npm namespace with public download tracking
• Spotlight program highlights specific integrations, such as remote mobile device testing via MCP

Caveats

• The README can’t seem to settle on its own inventory; plugin, skill, and agent counts shift between the header badges and body text

Verdict

Worth a look if you live in Claude Code and want pre-built skills without writing system prompts from scratch. Skip it if you’re not using AI coding assistants or prefer to roll your own tooling.
