Creating Cursor Slash Commands

You are an expert at creating effective Cursor slash commands (.cursor/commands/*.md) that provide clear, actionable instructions for AI assistants.

When to Use This Skill

Use when:

User wants to create a new Cursor slash command
User asks to improve existing slash commands
User needs help understanding Cursor command format
User wants to convert prompts to slash commands
User asks about Cursor command validation

Don't use for:

Cursor rules (.cursor/rules/) - use creating-cursor-rules-skill instead
Claude Code slash commands - those use different format with frontmatter
Complex multi-step workflows - those should be Cursor rules

Quick Reference

Aspect	Requirement
File Location	`.cursor/commands/*.md`
Format	Plain Markdown (NO frontmatter)
Filename	Descriptive kebab-case (e.g., `review-code.md`, `generate-tests.md`)
Invocation	`/command-name` in chat
Content	Clear, actionable instructions with examples

Format Requirements

Critical Rules

NO frontmatter allowed - Cursor commands are plain Markdown only
Descriptive filenames - The filename becomes the command name
Clear instructions - Tell AI exactly what to do
Include examples - Show desired output format

File Naming

Good filenames:

review-code.md → /review-code
generate-tests.md → /generate-tests
explain-code.md → /explain-code
optimize-performance.md → /optimize-performance

Bad filenames:

rc.md - Too cryptic
review_code.md - Use hyphens, not underscores
ReviewCode.md - Use lowercase
review-code-thoroughly-with-security-checks.md - Too verbose

Schema Validation

Schema Location

https://github.com/pr-pm/prpm/blob/main/packages/converters/schemas/cursor-command.schema.json

Schema Structure

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "$id": "https://prpm.dev/schemas/cursor-command.schema.json",
  "title": "Cursor Command Format",
  "description": "JSON Schema for Cursor commands (slash commands) - plain Markdown files in .cursor/commands/",
  "type": "object",
  "required": ["content"],
  "properties": {
    "content": {
      "type": "string",
      "description": "Plain Markdown content describing what the command should do. No frontmatter supported."
    }
  },
  "additionalProperties": false
}

Key Validations

Must be plain Markdown - No YAML frontmatter
Content-only structure - Single content field
No metadata - Unlike Cursor rules, commands have no configuration

Common Mistakes

Mistake	Why It's Wrong	How to Fix
Adding frontmatter	Cursor commands don't support frontmatter	Remove `---` blocks entirely
Using default exports syntax	Commands are not code files	Write plain Markdown instructions
Vague instructions	AI needs specific guidance	Add concrete examples and steps
Too many tasks	Commands should be focused	Create separate commands or use rules
Missing context	AI needs to know what to do	Include expected output format

Best Practices

1. Be Specific and Actionable

❌ Bad - Vague:

# Review Code

Review the code for issues.

✅ Good - Specific:

# Review Code

Review the selected code for:
- Code quality and best practices
- Potential bugs or edge cases
- Performance improvements
- Security vulnerabilities

Provide specific, actionable feedback with code examples where appropriate.

2. Include Expected Output Format

❌ Bad - No guidance:

# Generate Tests

Generate tests for this code.

✅ Good - Clear format:

# Generate Tests

Generate comprehensive unit tests for the selected code.

Include:
- Happy path test cases
- Edge cases and error handling
- Mock external dependencies
- Follow existing test patterns in the project

Use the testing framework already configured in the project.

3. Provide Step-by-Step Instructions

✅ Good - Structured approach:

# Explain Code

Provide a clear explanation of what the selected code does.

Include:
- High-level purpose and goals
- Step-by-step breakdown of logic
- Any non-obvious behavior or edge cases
- Dependencies and side effects
- How it fits into the larger codebase

4. Reference Project Context

✅ Good - Context-aware:

# Add Component

Create a new React component following our project conventions.

Structure:
- Functional component with TypeScript
- Props interface defined separately
- Export as named export (not default)
- Co-locate styles if needed
- Follow existing component patterns in components/ directory

Use the same testing approach as existing components.

5. Focus on One Task

Each command should do ONE thing well.

❌ Bad - Too broad:

# Full Stack Feature

Create a full-stack feature with:
- Database migration
- API endpoint
- Frontend component
- Tests for everything
- Documentation

✅ Good - Focused:

# Create API Endpoint

Create a new API endpoint following our conventions.

Include:
- Input validation with Zod
- Error handling with try/catch
- TypeScript types for request/response
- Follow patterns in existing endpoints

Examples

1. **Code Quality**
   - Clean, readable code
   - Proper naming conventions
   - DRY principle adherence

2. **Security**
   - Input validation
   - SQL injection risks
   - XSS vulnerabilities
   - Authentication/authorization checks

3. **Performance**
   - Inefficient algorithms
   - Unnecessary computations
   - Memory leaks
   - Database query optimization

4. **Best Practices**
   - Error handling

Apply these principles:

**Extract Functions:**
- Break down large functions (> 50 lines)
- Create single-responsibility functions
- Use descriptive names

**Simplify Logic:**
- Reduce nesting (early returns)
- Eliminate duplication
- Clarify complex conditionals

**Improve Names:**
- Use meaningful variable names
- Follow project naming conventions
- Avoid abbreviations

**Type Safety:**
- Add proper TypeScript types
- Eliminate 'any' types
- Use interfaces/types

Preserve all existing functionality and tests.

Bug Fix Command

.cursor/commands/fix-bug.md:

# Fix Bug

Analyze and fix the bug in the selected code.

Investigation steps:
1. Identify the root cause
2. Explain why the bug occurs
3. Propose a fix
4. Consider edge cases
5. Suggest tests to prevent regression

Fix requirements:
- Minimal changes to fix the issue
- Don't break existing functionality
- Add/update tests
- Add comments explaining the fix if non-obvious

Explain the fix clearly with before/after code examples.

Storage Locations

Commands can be stored in multiple locations (in order of precedence):

Project commands: .cursor/commands/ directory in your project (shared with team)
Global commands: ~/.cursor/commands/ directory (personal, all projects)
Team commands: Created via Cursor Dashboard (enterprise teams)

Best practice: Store team-wide commands in .cursor/commands/ and commit to version control.

Testing Your Commands

After creating a command:

Save to .cursor/commands/command-name.md
Invoke with /command-name in Cursor chat
Verify AI follows instructions correctly
Test edge cases:
- No code selected
- Empty files
- Complex code
- Different languages
Iterate based on results

Commands vs. Cursor Rules

Use Commands When:

✅ Simple, focused task
✅ Explicit user invocation desired
✅ Personal productivity shortcuts
✅ One-time operations

Use Cursor Rules When:

✅ Context-aware automatic activation
✅ File-type specific guidance
✅ Team standardization
✅ Always-on conventions

Example:

Command: /generate-tests - Explicitly generate tests when asked
Rule: Auto-attach testing conventions to *.test.ts files

Validation Checklist

Before finalizing a command:

Converting from Other Formats

From Claude Code Slash Commands

Claude Code commands use frontmatter - remove it for Cursor:

Claude Code:

---
description: Review code
allowed-tools: Read, Grep
---

Review the code...

Cursor:

# Review Code

Review the code...

From Cursor Rules

Rules use frontmatter and are context-aware - simplify to plain Markdown:

Cursor Rule:

---
description: Testing conventions
globs: ["**/*.test.ts"]
---

# Testing Standards

Always write tests...

Cursor Command:

# Generate Tests

Generate comprehensive tests...
