Terraform Testhashicorp/agent-skillsComprehensive guide for writing and running Terraform tests. Use when creating test files (.tftest.hcl), writing test scenarios with run blocks, validating infrastructure behavior with assertions, mocking providers and data sources, testing module outputs and resource configurations, or troubleshooting Terraform test syntax and execution.04Terraform Validatorakin-ozer/cc-devops-skillsValidate, lint, audit, or plan Terraform/.tf/HCL files; runs tflint, checkov, terraform validate.012Terragrunt Generatorakin-ozer/cc-devops-skillsGenerate/create/scaffold Terragrunt HCL files — root.hcl, terragrunt.hcl, child modules, stacks, multi-env layouts.09Terragrunt Validatorakin-ozer/cc-devops-skillsValidate, lint, audit, or check Terragrunt .hcl/terragrunt.hcl files, stacks, modules, compliance.031Tesla Fleet APIodrobnik/tesla-fleet-api-skillUse when integrating with Tesla's official Fleet API to read vehicle/energy device data or issue remote commands (e.g. start HVAC preconditioning, wake vehicle, charge controls). Covers onboarding (developer app registration, regions/base URLs), OAuth token flows (third-party + partner tokens, refresh rotation), required domain/public-key hosting, and using Tesla's official vehicle-command/tesla-http-proxy for signed vehicle commands.015Teslers Lawowl-listener/designer-skillsApply Tesler's Law — every process has irreducible complexity that someone must absorb. Use when deciding whether the product or the user carries it. For reducing apparent choice, use `hicks-law`.01Testjsmastery-pro/skillsRun /test to write a test suite for code you just built or changed, after implementing a feature, route, or fix. Targets uncommitted changes automatically, reads test preferences.json for your framework (asks and saves it if absent), and picks the right strategy per file: happy path, edge cases, error states, accessibility.05Testparcadei/continuous-claude-v3Comprehensive testing workflow - unit tests ∥ integration tests → E2E tests01Testreact/reactUse when you need to run tests for React core. Supports source, www, stable, and experimental channels.01Test Analysis Extensionsdotnet/skills>-012Test Anti Patternsdotnet/skills>01Test Automation Frameworkaj-geddes/useful-ai-prompts>010Test Automatorzhaono1/agent-playbookTest automation framework expert for creating and maintaining automated tests. Use when user asks to write tests, automate testing, or improve test coverage.08Test Case Managementpetrkindlmann/qa-skills>-04Test Case Writingnaodeng/awesome-qa-skillsUse this skill when you need to create high-quality test cases with normal, exception, and boundary scenarios; triggers include test case writing and test design.036Test Casesstellarlinkco/myclaudeThis skill should be used when generating comprehensive test cases from PRD documents or user requirements. Triggers when users request test case generation, QA planning, test scenario creation, or need structured test documentation. Produces detailed test cases covering functional, edge case, error handling, and state transition scenarios.02Test Coveragecognitedata/builder-skillsMUST be used whenever fixing test coverage for a Flows app to meet the 80% line coverage hard gate. This skill finds AND fixes coverage gaps — it configures tooling, writes missing tests, covers untested paths, and refactors code for testability. It does not just report. Triggers: test coverage, fix tests, write tests, add tests, coverage fix, 80% coverage, coverage gate, missing tests, testability, vitest coverage, jest coverage.01Test Coverageneolabhq/context-engineering-kitUse after writing tests to assess coverage quality across structural, mutation, requirements, and API/integration dimensions; organized knowledge for choosing and interpreting coverage analyses.01Test Data Generationaj-geddes/useful-ai-prompts>07Test Data Managementpetrkindlmann/qa-skills>-03Test Driven Developmentdavila7/claude-code-templatesUse when implementing any feature or bugfix, before writing implementation code02Test Driven Developmentjnmetacode/superpowers-zh在实现任何功能或修复 bug 时使用，在编写实现代码之前02Test Driven Developmentneolabhq/context-engineering-kitUse when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first01Test Driven Developmentsickn33/agentic-awesome-skillsUse a failing behavioral test to guide a feature or bug fix, then implement and refactor with relevant regression checks.02Test Environmentspetrkindlmann/qa-skills>-03Test Fixingmhattingpete/claude-skills-marketplaceRun tests and systematically fix all failing tests using smart error grouping. Use when user asks to fix failing tests, mentions test failures, runs test suite and failures occur, or requests to make tests pass.01Test Fixingsickn33/agentic-awesome-skillsSystematically identify and fix all failing tests using smart grouping strategies. Use when explicitly asks to fix tests (\"fix these tests\", \"make tests pass\"), reports test failures (\"tests are failing\", \"test suite is broken\"), or completes implementation and wants tests passing.01Test Gap Analysisdotnet/skills>-02Test Gapsruvnet/rufloDetect missing test coverage and generate test suggestions. Use when the user asks about coverage gaps, untested code, or what tests to write next; also after adding a feature to find what still needs tests.01Test Guardamelnagdy/guard-skillsReview generated or changed test code against universal testing rules before it ships. Best used reactively after an agent writes, edits, generates, or refactors tests, before presenting, committing, or merging them. Use for pytest (test_*.py, *_test.py), PHPUnit/Pest (*Test.php), Jest/Vitest (*.test.ts, *.spec.js), Go (*_test.go), files under tests/, __tests__/, or spec/, and review requests like 'write tests for X', 'add tests', 'test this', 'review these tests', or PR diffs containing tests. Can also guide test writing when explicitly invoked before the work. This skill is the quality gate that prevents AI-generated test bloat. DO NOT USE for production or implementation code review (use clean-code-guard), CI or test-runner configuration, running or debugging tests, or general architecture discussion.06Test Harnesszernie/vigilesInstall vigiles and test a Claude Code harness — hooks, skills, agents, settings, CLAUDE.md — by picking the right tier (unit / deterministic / eval) and writing a test that passes. Use to check that a hook fires or blocks, that a skill triggers, that injected context lands; or to observe a run — which tools it called, whether it stayed inside its declared allowed-tools, what files and side effects it produced, how to intercept a call without executing it.04Test Masterjeffallan/claude-skillsGenerates test files, creates mocking strategies, analyzes code coverage, designs test architectures, and produces test plans and defect reports across functional, performance, and security testing disciplines. Use when writing unit tests, integration tests, or E2E tests; creating test strategies or automation frameworks; analyzing coverage gaps; performance testing with k6 or Artillery; security testing with OWASP methods; debugging flaky tests; or working on QA, regression, test automation, quality gates, shift-left testing, or test maintenance.011Test Migrationpetrkindlmann/qa-skills>-03Test Modernizersuperagents-lab/xcode27-skillsModernize test suites to use modern Swift Testing features or migrate from XCTest.01Test Planningpetrkindlmann/qa-skills>-04Test Playable Web Gamesmengto/skillsTest a playable browser game end to end with deterministic fixtures and real browser evidence. Use for gameplay QA, regression testing, controls, accessibility, responsive/mobile testing, save flows, console checks, performance smoke tests, and release verification.02Test Promptneolabhq/context-engineering-kitUse when creating or editing any prompt (commands, hooks, skills, subagent instructions) to verify it produces desired behavior - applies RED-GREEN-REFACTOR cycle to prompt engineering using subagents for isolated testing01Test Quality Analysissecondsky/claude-skillsDetect test smells, overmocking, flaky tests, and coverage issues. Analyze test effectiveness, maintainability, and reliability. Use when reviewing tests or improving test quality.01Test Reliabilitypetrkindlmann/qa-skills>-02Test Scenarioowl-listener/designer-skillsWrite realistic usability task scenarios with success criteria and facilitation notes. Use when you have a study and need the tasks. For the surrounding study design, use `usability-test-plan` (design-research).01Test Scenariosphuryn/pm-skillsCreate comprehensive test scenarios from user stories with test objectives, starting conditions, user roles, step-by-step actions, and expected outcomes. Use when writing QA test cases, creating test plans, defining acceptance tests, or preparing for feature validation.01Test Skillneolabhq/context-engineering-kitUse when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes01Test Smell Detectiondotnet/skills>02Test Specialistailabs-393/ai-labs-claude-skillsThis skill should be used when writing test cases, fixing bugs, analyzing code for potential issues, or improving test coverage for JavaScript/TypeScript applications. Use this for unit tests, integration tests, end-to-end tests, debugging runtime errors, logic bugs, performance issues, security vulnerabilities, and systematic code analysis.07Test Strategypetrkindlmann/qa-skills>-03Test Suite Curationpetrkindlmann/qa-skills>-08Test Taggingdotnet/skills>01Test Tuiopenai/codexGuide for testing Codex TUI interactively01
