AI Agent Skills provide specialized behavioral instructions, domain knowledge, workflows, and guardrails to autonomous AI coding agents like Cursor, Claude Code, Windsurf, Google Antigravity, and Andromity.
While MCP (Model Context Protocol) Servers provide external APIs and tools (like databases, GitHub, or terminal execution), an Agent Skill (SKILL.md) teaches the agent how to reason, make architectural decisions, follow project conventions, and execute complex multi-step workflows.

Every skill on AgenticMarket includes an interactive Copy Prompt button.
The prompt instructs the agent to create the appropriate SKILL.md or rule file in your project:
markdownYou are an expert pair programmer. I want you to install the "mcp-builder" skill. Create the directory .agent/skills/mcp-builder/ and write the SKILL.md specification...
You can also download and install raw SKILL.md files directly using terminal commands:
bashmkdir -p .agent/skills/mcp-builder && curl -fsSL https://agenticmarket.dev/api/skills/mcp-builder/raw -o .agent/skills/mcp-builder/SKILL.md
powershellNew-Item -ItemType Directory -Force -Path ".agent\skills\mcp-builder"; irm https://agenticmarket.dev/api/skills/mcp-builder/raw | Out-File -FilePath ".agent\skills\mcp-builder\SKILL.md" -Encoding utf8
