The Problem: AI Agent Skills Are a Security Minefield
AI coding agents like Claude Code, Cursor, and Cline have become essential tools for professional developers. They write code, refactor projects, debug issues, and automate workflowsβbut they're only as capable as the skills (plugins/extensions) you give them.

How It Works: Architecture & CDN
Agent Skills uses on-demand fetching from a CDN for fast, offline-capable installs:
@tech-leads-club/agent-skills-mcp is an MCP server that exposes the skills catalog directly to AI agents via progressive disclosureβsearch first, then fetch only what's needed.
MCP Tools
list_skills β Browse all skills by category (only call when user explicitly requests browsing).
search_skills β Find skills by intent (fuzzy search across names, descriptions, categories).
read_skill β Load a skill's main instructions (SKILL.md content).
fetch_skill_files β Fetch specific reference files (templates, docs).
π€ AI skill generator β Generate skills from natural language descriptions
π Telemetry β Opt-in anonymous usage data for skill authors
π Multi-language β Skills in non-English languages
