Skillsets.cc

It's hard to trust Claude Code extentions. Skillsets.cc is raising that bar with a high-signal reputation foundry for power-users who ship more than they talk, and low-noise discovery engine for those who want to learn from the best.

This addresses the fundamental weakness with the extension ecosystem, which is growing at an exponential rate with no quality infrastructure. No verification, no integrity checks, little dependency transparency, and no real way to pinpoint the proven production stacks in a jungle of slop. See PROBLEM_SPACE.md for the full landscape analysis.

What is a Skillset?

A skillset is an integrated Claude Code workflow that met the bar and actually shipped software. Expertly forged combinations of primitives, and sometimes custom support-stacks, in unholy union and at your service. It's the core operating environment, not an add-on.

We only accept complete workflows that have shipped real software, with clear documentation and evidence of production use.

The Bar

Contributions are limited to bi-monthly cohorts of 10. Every submission passes through three verification tiers before it reaches the registry.

Structural audit validates manifest schema, required files, content structure, file sizes, binary detection, secrets scanning, and README formatting. If the structure isn't clean, the process stops here.

Qualitative review. Our review agent evaluates every primitive — skills, agents, hooks, MCP servers, CLAUDE.md — against published criteria. Third-party MCP servers and runtime dependencies are researched for provenance and reputation. A safety scan checks all primitives for prompt injection and exfiltration. The reviewer then searches the contributor's reference repo for collaboration artifacts — design docs, execution docs, analysis reports — as evidence the skillset actually shipped software. Findings are appended to the audit report with a verdict.

Human approval. A maintainer reviews the production proof, the documentation, and both audit tiers, then signs off. CI re-runs structural validation on the final PR state.

The result is a small, high-trust catalog where everything listed has been structurally validated, qualitatively reviewed, and human-approved.

Browse & Install

Visit skillsets.cc to browse the registry, or search from within Claude Code:

# Add the curated marketplace (once)
claude plugin marketplace add skillsets-cc/main

# Browse and search the registry
/browse

# Install a skillset
/install <name>

/install is an onboarding agent, not a file extractor. Claude installs the skillset, then walks you through customizing it for your project — so you land in a working environment, not a pile of extracted files.

Skillsets come with all the guarantees of probabilistic space — as with any OSS, verify before you trust.

We All Want To Learn From You

You built a high-dimensional skillset, not a toy. Give it a dedicated repo, spin up Claude Code, install the marketplace and contribute plugin, and run the following command:

/contribute

This is our submission agent. It scaffolds your structure, helps you prepare content and production proof, runs structural validation and the qualitative audit, then submits the PR. The full process and requirements are documented in CONTRIBUTING.md.

What We Solve For

The technical structure solves for four interconnected pain points:

For end users, you're assembling individual primitives yourself and hoping they work together. You can't tell what's compatible and what's been vetted. You don't know what dependencies come along for the ride. And installation dumps files with no guidance on how to configure them for your project. Skillsets.cc inverts all of that: verified complete workflows, dependency transparency at install time, and an onboarding agent that sets it up with you.

For contributors, if you built an integrated Claude Code workflow there's no distribution channel for it. Your production stack sits next to a weekend experiment of dubious provenance and there's no way to tell them apart. Publishing through skillsets.cc gives your work structural validation, a qualitative review, dependency attestation, and a verified listing with built-in promotion. The submission agent runs the full process without ever leaving Claude Code, and the onboarding agent on the install side means your skillset actually gets adopted.

For maintainers, it's a programmatically constrained workload. Bi-monthly cohorts capped at 10, that only increase when the team grows. Two automated audit tiers gate submissions before human review. The site, auth, and API run as a single Cloudflare Worker. There is no traditional backend to maintain — just a mono-repo, an astro site, a schema, a three-skill plugin, a micro-CLI, and a Worker.
