Software Engineer Claude Skills
Software engineers are among the highest adopters of AI tools in 2026. These 8 Claude Agent Skills turn Claude into a specialised development partner for your daily workflow — from writing production-ready code and debugging complex errors to designing system architecture and setting up CI/CD pipelines. Each skill is a downloadable SKILL.md file you can install directly in Claude Code, claude.ai, or the Claude API.
Writing Code with AI
IntermediateGenerates production-ready code in any language or framework, explains architectural decisions, suggests design patterns, and follows project conventions. Use when asked to write, create, implement, scaffold, or build any code, function, class, component, or module.
$When you need to implement a new feature, function, or component from scratch.
Reviewing Code
IntermediatePerforms multi-pass code review covering correctness, security vulnerabilities, performance bottlenecks, readability, and adherence to best practices. Use when asked to review, check, audit, critique, or give feedback on any code.
$When you want a thorough review before merging a pull request or submitting code.
Debugging Errors
BeginnerAnalyses error messages, stack traces, and runtime logs to identify root causes and provide targeted fixes with explanations. Use when the user shares an error message, exception, stack trace, failing test output, or describes unexpected behaviour.
$When your code throws an error or behaves unexpectedly and you need to find and fix the cause.
Writing Tests
IntermediateCreates comprehensive test suites including unit tests, integration tests, and edge cases for any function, class, API endpoint, or component. Use when asked to write tests, add test coverage, create test cases, or test a specific piece of code.
$When you need tests written for new or existing code to ensure correctness.
Architecting Systems
AdvancedDesigns scalable system architecture, data models, API contracts, microservice boundaries, and infrastructure diagrams. Use when asked to design a system, architect a solution, plan a database schema, or decide on technical approach for a new feature or product.
$When starting a new system, service, or major feature and needing an architectural plan.
Generating Technical Docs
BeginnerAuto-generates README files, API documentation, inline code comments, JSDoc/TSDoc, and technical specifications from source code or descriptions. Use when asked to document, write a README, create API docs, or add comments to code.
$When you need documentation written for a codebase, function, or API.
Optimising Performance
AdvancedIdentifies performance bottlenecks in code, databases, and front-end rendering, then provides targeted optimisations with before/after comparisons. Use when code is slow, pages load slowly, queries are taking too long, or the user mentions performance, latency, or optimisation.
$When you need to make code, queries, or pages significantly faster.
Planning DevOps Setup
AdvancedDesigns CI/CD pipelines, Docker/Kubernetes configurations, GitHub Actions workflows, and infrastructure-as-code templates. Use when asked about deployment, pipelines, containers, CI/CD, infrastructure, or DevOps setup.
$When setting up deployment infrastructure, CI/CD, or containerisation for a project.
