 ## What are agent skills?
 
 Skills are portable instruction sets that teach AI coding assistants how to use Trigger.dev effectively. Unlike vendor-specific config files (`.cursor/rules`, `CLAUDE.md`), skills use an open standard that works across all major AI assistants. For example, Cursor users and Claude Code users can get the same knowledge from a single install.
 
 <Note>
-  Skills are one of three AI tools we provide. You can also install [Agent Rules](/mcp-agent-rules) for client-specific rule sets or the [MCP Server](/mcp-introduction) for live project interaction. See the [comparison table](/building-with-ai#skills-vs-agent-rules-vs-mcp) for details.

 Skills are installed as directories containing a `SKILL.md` file. Each `SKILL.md` includes YAML frontmatter (name, description) and markdown instructions with patterns, examples, and best practices that AI assistants automatically discover and follow.
