Agent Skills & Slash Commands

Reusable Expertise for Your Agent

Agent Skills package domain knowledge into folders the agent can discover and use. Cursor implements the open Agent Skills standard (agentskills.io) — the same format used by other AI coding tools, so skills are portable across ecosystems.

# Deploy Checklist
1. Run the full test suite
2. Verify env config against .env.example
3. Build locally before pushing to the platform

The frontmatter also supports paths globs (auto-activate the skill for matching files) and disable-model-invocation (make it slash-command-only). Skills live at project level (.cursor/skills/, .agents/skills/) or user level (~/.cursor/skills/), with nested directories for monorepo scoping — and Cursor even reads skills from compatible tools' directories.

Built-In Slash Commands

Type / in the agent input to invoke built-in skills:

CommandWhat It Does
/create-skill, /create-rule, /create-hookScaffold a new skill, rule, or hook
/review, /review-security, /review-bugbotIn-editor code review before you push
/loopRepeat a prompt on a schedule until a condition is met
/split-to-prsBreak a big diff into reviewable stacked PRs
/automateCreate an always-on Automation (see Cloud Agents)
/migrate-to-skillsConvert legacy rules/commands into the skills format

The Customize Page

Since Cursor 3.8, the Customize page is one place to manage plugins, skills, MCP servers, subagents, rules, commands, and hooks — at user, team, or workspace scope — plus a marketplace with a leaderboard of popular extensions.

Pro Tip: Rules vs Skills — rules are always-available context; skills are on-demand capabilities with scripts and reference material. If your instructions include "how to do X step-by-step", it probably wants to be a skill.
