What is Agent Skills?

Agent Skills is a curated collection of skills for AI coding agents, created by Tech Leads Club. It extends Cursor, Claude Code, GitHub Copilot, Windsurf, Cline, Antigravity, and many other AI assistants with reusable, packaged instructions that teach agents new workflows, patterns, and specialized knowledge. Think of skills as plugins for your AI assistant—they provide battle-tested playbooks for shipping, security, architecture, accessibility, cloud deployment, and more.

The platform offers 56 skills across 14 categories including Quality, Cloud & Infrastructure, Development, Architecture, Performance, Tooling, Design, and Automation. Each skill is security-scanned with Snyk Agent Scan before publishing, human-curated, and validated for quality. Skills are installed directly from the command line using npx @tech-leads-club/agent-skills install --skill [skill-name] and go into your agent's skills directory (e.g., .cursor/skills/, .claude/skills/).

Key features include a secure, validated skill registry where 100% of the code is open source with no binaries, static analysis in CI/CD, immutable integrity via lockfiles and content hashing, and defense-in-depth installation with sanitization and path isolation. The CLI supports interactive mode, batch installation, global or local scope, symlink or copy installation, caching for offline use, and an MCP server for AI agents to browse and fetch skills via progressive disclosure.

Agent Skills is designed for professional developers, engineering teams, and organizations using AI coding agents who need trustworthy, vetted capabilities instead of random internet advice. It's particularly valuable for enterprises concerned about AI supply chain security, as over 13% of open marketplace skills contain critical vulnerabilities while Agent Skills provides a hardened library with human review.

Frequently asked questions about Agent Skills

What are Agent Skills?

Skills are packaged instructions and resources that extend AI agent capabilities. Think of them as plugins for your AI assistant—they teach your agent new workflows, patterns, and specialized knowledge. Each skill contains a SKILL.md file with main instructions, templates for file generation, and references for on-demand documentation.

Which AI agents support Agent Skills?

Agent Skills supports 19+ AI coding agents across three tiers. Tier 1 (Popular): Claude Code, Cline, Cursor, GitHub Copilot, Windsurf. Tier 2 (Rising): Aider, Antigravity, Gemini CLI, Kilo Code, Kiro, OpenAI Codex, Roo Code, TRAE. Tier 3 (Enterprise): Amazon Q, Augment, Droid (Factory.ai), OpenCode, Sourcegraph Cody, Tabnine.

How do I install a skill?

Install skills using the CLI: npx @tech-leads-club/agent-skills install --skill [skill-name]. This launches an interactive wizard where you can browse skills by category, select target agents, choose installation method (copy or symlink), and pick global or local scope. Skills install to your agent's skills directory like .cursor/skills/ or .claude/skills/.

Is Agent Skills secure?

Yes. Unlike open marketplaces where 13.4% of skills contain critical vulnerabilities, Agent Skills is a managed, hardened library. Every skill is scanned with Snyk Agent Scan before publishing, 100% open source with no binaries, includes static analysis in CI/CD, uses immutable integrity via lockfiles and content hashing, and has human-curated prompts with defense-in-depth installation.

Can I create my own skills?

Yes, contributions are welcome. The repository is open source and follows CONTRIBUTING.md guidelines for setting up local environment, creating new skills, and contributing to the marketplace. Skills follow a structure with SKILL.md for instructions, templates/ for file templates, and references/ for documentation.

What licensing applies to Agent Skills?

The CLI software engine is MIT Licensed. Tech Leads Club-authored skills (SKILL.md files) use Creative Commons Attribution 4.0 International License (CC-BY-4.0). Third-party community skills retain their original licenses. Attribution to Tech Leads Club is required when using the skills catalog regardless of how it's used.

How does caching work?

Downloaded skills are cached in ~/.cache/agent-skills/ for offline use. You can clear the cache with agent-skills cache --clear or clear only the registry with agent-skills cache --clear-registry. The CLI fetches the skills catalog (~45KB) on-demand from their CDN.

What is the MCP Server?

@tech-leads-club/agent-skills-mcp is an MCP server exposing the skills catalog directly to AI agents via progressive disclosure. It provides tools: list_skills (browse by category), search_skills (fuzzy search by intent), read_skill (load main instructions), and fetch_skill_files (fetch specific references). Install via NPM in your MCP configuration.

Can I update or remove skills?

Yes. Update a specific skill with agent-skills update -s [skill-name] or all skills with agent-skills update. Remove a skill with agent-skills remove -s [skill-name] or multiple skills at once. You can also remove from specific agents using -a flag and force removal with --force to bypass lockfile checks.

What categories of skills are available?

The collection includes 14 categories: Quality (best-practices, accessibility), Cloud & Infrastructure (aws-advisor, cloudflare-deploy), Development (coding-guidelines, confluence-assistant), Architecture (component-common-domain-detection, coupling-analysis), Performance (core-web-vitals), Tooling (chrome-devtools), Design (figma), Automation (playwright-skill), Security (security-best-practices), and more for SEO, documentation, and web audits.
