Your AI assistant’s new middle-management layer, in stdlib Python

What it does Claude-Skills is a sprawling library of prompts, expert personas, and Python utilities designed to turn generalist AI assistants into specialists across 20 business domains. It ships 368 skills—from startup-cto to cs-fintech-advisor—plus 859 standard-library Python scripts you can pipe into CI or MCP servers. A bundled installer drops the assets into the correct directories for Claude Code, Cursor, Copilot, and eight other assistants.

The interesting bit Most prompt libraries are toy templates; this one treats AI assistants like a workforce you can staff. You call /persona startup-cto and get a stack of cross-domain skills behind it, or invoke slash commands like /tdd and /rice to run deterministic workflows. The project-management domain alone has 68 skills with anti-pattern libraries and scoring rubrics—an unusual level of structure for what is essentially a very large prompt-and-script repo.

Key highlights

• 18 compliance frameworks (SOC 2, GDPR, EU AI Act, HIPAA) with checklists and gap analyses, which the authors claim is the only open-source skills library covering regulated industries.
• 76 pre-built expert identities, from growth-marketer to cs-scrum-master, that combine domain-specific skills into callable personas.
• Standard-library-only Python tools—no pip dependencies—meant to be piped into CI or wired up as MCP tools.
• Tiered product-management skills with strategy frameworks (BMC, Lean Canvas, Porter’s), anti-pattern libraries, and integrations with Jira, Linear, Notion, Productboard, and Confluence.
• MIT license with a Commons Clause add-on: free for internal use, but cannot be repackaged and sold as a paid product.

Caveats

• The README includes a frank disclaimer that all content is AI-generated and may contain errors; the authors explicitly warn against using compliance, legal, or financial skills in production without independent verification.
• The repository is overwhelmingly broad—368 skills across 20 domains means depth varies, and the README notes that project management is the deepest domain.
• Detailed setup for the MCP server and per-platform installation lives in external docs rather than the README.

Verdict Grab this if you want your AI assistant to stop acting like an intern and start acting like a specialized consultant—provided you verify its homework before filing with the FDA or presenting to the board. Skip it if you are looking for a runtime or framework; this is a content library with an installer, not an engine.
