Every project benefits from consistent code reviews. A Code Review Skill automatically analyses your code for bugs, security issues, performance bottlenecks, code smells, and maintainability problems before you merge changes.
Best for: Every developer
2. Documentation Generator#
Keeping documentation updated is often overlooked. This Skill generates READMEs, API documentation, function comments, and onboarding guides directly from your codebase.
Best for: Open-source projects and SaaS teams

Generate unit tests, integration tests, mocks, and edge cases for frameworks like Jest, Vitest, Pytest, and JUnit, helping you improve test coverage with minimal effort.
Best for: Backend and full-stack developers
4. Debugging Assistant#
Instead of spending hours tracing stack traces, this Skill analyses runtime errors, logs, dependency issues, and build failures to quickly identify the root cause.
Best for: Developers working on large applications
5. API Development Skill#
Build REST and GraphQL APIs faster by generating endpoints, validation, authentication, OpenAPI documentation, and error handling following best practices.
Best for: Node.js, FastAPI, Django, and Spring Boot developers

Improve code readability and maintainability by identifying duplicate logic, simplifying complex functions, and modernising legacy code without changing behaviour.
Best for: Long-term software projects
7. Security Auditor#
Automatically scan your project for common vulnerabilities such as SQL injection, XSS, insecure authentication, exposed secrets, and dependency risks.
Best for: Production applications
8. DevOps Assistant#
Generate Dockerfiles, CI/CD pipelines, GitHub Actions workflows, Kubernetes manifests, and deployment configurations to simplify infrastructure management.
Best for: Full-stack developers and startups
9. AI Agent Builder#
If you're building AI applications, this Skill helps create MCP servers, RAG pipelines, tool-calling workflows, memory systems, and multi-agent architectures.
Best for: AI engineers
10. Git Workflow Assistant#
Automate commit messages, pull request descriptions, release notes, changelogs, and branch naming conventions for a smoother development workflow.
Best for: Collaborative engineering teams
