• Generating API documentation automatically
• Creating code docstrings
• Writing README files with examples
• Building usage guides
• Documenting configuration options

How to set up:

Example output:

json

{

"email": "user@example.com",

"username": "johndoe",

"password": "secure_password",

"full_name": "John Doe"

}

json

{

"id": "user_123",

"email": "user@example.com",

"username": "johndoe",

"created_at": "2024-02-20T10:30:00Z"

}

Pro tips:

• Run after major features complete
• Supports multiple documentation formats
• Can target different audience levels
• Includes code examples and error scenarios

5. Pull Request Review Skill

What it does: Comprehensive review of pull requests including code quality, tests, documentation, and impact assessment.

Use cases:

• Automated PR quality checks
• Identifying missing tests or documentation
• Assessing breaking changes
• Checking for security issues
• Evaluating architectural decisions

How to set up:

Example output:

Pro tips:

• Use before assigning human reviewers
• Focuses on objective criteria, not subjective style
• Identifies gaps in testing and documentation
• Provides specific, actionable recommendations

6. Security Audit Skill

What it does: Scans code for security vulnerabilities, misconfigurations, and compliance issues.

Use cases:

• Finding OWASP Top 10 vulnerabilities
• Identifying authentication/authorization issues
• Detecting secret leakage risks
• Checking dependency vulnerabilities
• Assessing compliance with security standards

How to set up:

Example output:

python

query = f"SELECT * FROM users WHERE id = {user_id}"

python

query = "SELECT * FROM users WHERE id = ?"

cursor.execute(query, (user_id,))

python

DB_PASSWORD = os.getenv("DB_PASSWORD")

Pro tips:

• Run before every production deployment
• Prioritize critical issues immediately
• Use multiple standards (OWASP, PCI-DSS, SOC2)
• Integrate into CI/CD pipeline for continuous checking

7. Performance Optimization Skill

What it does: Identifies performance bottlenecks and recommends optimizations with expected impact.

Use cases:

• Finding slow queries and database issues
• Identifying inefficient algorithms
• Memory leak detection
• Cache optimization opportunities
• API response time improvement

How to set up:

Example output:

python

for user in users:

posts = db.query(Post).filter(Post.user_id == user.id).all()

python

users_with_posts = db.query(User).options(

joinedload(User.posts)

).all()

Pro tips:

• Run on production-like datasets
• Profile before and after optimizations
• Focus on biggest impact items first
• Don't optimize prematurely; measure first

8. Refactoring Assistant Skill

What it does: Identifies opportunities for code simplification, consolidation, and maintainability improvements.

Use cases:

• Reducing code duplication
• Simplifying complex functions
• Improving naming clarity
• Extracting reusable components
• Improving code organization

How to set up:

Example output:

python

# shared/validators.py

def validate_email(email: str) -> bool:

"""Validate email format with proper error messages"""

# implementation

python

if user:

if user.is_active:

if user.has_payment_method:

if payment_amount > 0:

# process...

python

if not is_valid_payment(user, amount):

return error()

process_payment(user, amount)

Pro tips:

• Refactor in small, testable increments
• Use before major version releases
• Prioritize duplication and complexity
• Keep tests green throughout refactoring

9. API Design Skill

What it does: Reviews API design for consistency, usability, and adherence to REST principles.
