Agent skills
Skills you can use with AI coding agents, indexed from public GitHub repositories.
-
testing-test-writing
Write minimal, focused tests for core user flows and critical paths during development, testing behavior rather than implementation with clear test names and mocked dependencies. Use this skill when writing unit tests, integration tests, test files, test cases for critical workflows, or mocking external dependencies. Apply when working with test files (.test.js, .spec.ts, _test.py), test frameworks (Jest, RSpec, pytest), testing user journeys, or implementing fast-executing tests that validate business-critical functionality without over-testing implementation details or edge cases during feature development.

Design and build reusable, composable UI components following single responsibility principle with clear props, proper encapsulation, and minimal state management. Use this skill when creating or modifying React, Vue, Svelte, or web components, defining component props or interfaces, managing component state, building component libraries, or refactoring UI code. Apply when working with .jsx, .tsx, .vue, .svelte files, component directories, or any code that defines reusable UI building blocks with configurable interfaces and composable architectures.

global-conventions
Follow project-wide development conventions including project structure, version control practices, environment configuration, documentation, dependency management, and code review processes. Use this skill when organizing files/directories, writing commit messages, managing branches, configuring environments, handling secrets, maintaining documentation, or establishing team workflows. Apply when working with project structure, README files, .gitignore, environment variables, dependency files (package.json, requirements.txt), feature flags, changelogs, or any aspect of project organization and team collaboration that requires consistency across the development lifecycle.

frontend-responsive
Build mobile-first responsive layouts with fluid containers, relative units, standard breakpoints, and touch-friendly design that adapts seamlessly across devices. Use this skill when creating or modifying layouts, implementing media queries, defining breakpoints, choosing sizing units, optimizing for mobile devices, or testing UI across screen sizes. Apply when working with responsive design, mobile layouts, tablet views, desktop views, viewport configuration, or any styling that needs to adapt to different screen sizes and device capabilities.

backend-models
Define database models and ORM entities with proper naming, relationships, validation, and data integrity constraints. Use this skill when creating or modifying model classes, database table definitions, model relationships (one-to-many, many-to-many), data validation rules, database constraints, or model methods. Apply when working with ORM model files, ActiveRecord, SQLAlchemy, Sequelize, Prisma schemas, or any database model definitions that map objects to database tables and enforce data structure and relationships.

global-validation
Implement comprehensive server-side validation with allowlists, type checking, input sanitization, and consistent error messages, while using client-side validation for user experience. Use this skill when validating user input, form data, API requests, implementing security checks, preventing injection attacks, checking data types/formats/ranges, or providing validation feedback. Apply when working with form validation, API endpoint validation, input sanitization, business rule enforcement, or any code that accepts and validates external data to ensure security, data integrity, and proper user feedback across all entry points.

global-commenting
Write self-documenting code with minimal, evergreen comments that explain complex logic without describing recent changes or temporary fixes. Use this skill when writing code comments, documentation strings, explaining complex algorithms, clarifying business logic, or deciding whether code needs comments. Apply when working with any source code files where comments or documentation might be added, ensuring comments remain relevant, helpful, and focused on explaining why rather than what the code does, while preferring clear code structure and naming over excessive commenting.

global-error-handling
Implement robust error handling with user-friendly messages, specific exception types, fail-fast validation, centralized error boundaries, graceful degradation, and proper resource cleanup. Use this skill when writing try-catch blocks, raising exceptions, handling API errors, validating input, implementing error boundaries, managing external service failures, or ensuring resource cleanup. Apply when working with error handling code in any language, exception classes, error middleware, API error responses, retry logic, or any code that needs to handle failures gracefully while maintaining system stability and providing clear feedback to users.
