- make-voxhassancs91/claude-faceless-shorts-creatorBuild a Vox-style LAYERED-COLLAGE vertical short end-to-end — script + scene dissection into image layers, layer production (AI images via gen_image.py + cutout.py, HTML→PNG, SVG-in-TSX), choreographed TSX assembly on the collage kit (CollageBoard camera, parallax, cutouts, chips, routes), frame QA, render, then voice/SFX via the shared machinery. Use when the user wants a "vox style", documentary, or explainer-collage short, a map-travel or archival-history sequence, or to continue the vox-N series — the paper-collage look, not plain TSX animation (that is make-short) and not video-model pixels (that is make-ai-short). Defers raw TSX crash rules to vidtsx-2d-generator and SFX taste to suggest-sfx.TestingNo warnings★ 280↓ —

- upgrade-prachtJoviDeCroock/prachtUpgrade the `@pracht/*` packages safely: inventory installed versions, read the changelogs between installed and target, map breaking changes to real usage, apply, then walk the verification ladder (doctor, typegen, verify, build, tests). Use for "upgrade pracht", "update @pracht packages", "bump the framework", "what changed in the new pracht version", "is this upgrade safe".TestingNo warnings★ 103↓ —

Outputs structured test suites ready for implementation.TestingNo warnings★ 258↓ —
- bug-localizationArabelaTso/Skills-4-SEIdentify the precise location of bugs in source code, modules, and systems. Use this skill when debugging applications, investigating test failures, analyzing error reports, tracing runtime issues, or performing root cause analysis. Analyzes stack traces, error messages, failing tests, and code patterns to pinpoint buggy functions, classes, files, or modules with confidence rankings and supporting evidence.TestingNo warnings★ 258↓ —
- coverage-enhancerArabelaTso/Skills-4-SEAnalyze existing test suites and source code to suggest additional unit tests that improve test coverage. Use this skill when working with test files and source code to identify untested code paths, missing edge cases, uncovered branches, untested error conditions, and gaps in test coverage. Supports major testing frameworks (pytest, Jest, JUnit, Go testing, etc.) and generates targeted test suggestions based on coverage analysis.TestingNo warnings★ 258↓ —
- java-test-updaterArabelaTso/Skills-4-SEUpdate Java test classes and methods to work with new code versions after refactoring or modifications. Use when code changes break existing tests due to signature changes, refactoring, or behavior modifications. Takes old and new code versions plus old tests as input, and outputs updated tests that compile and pass against the new code. Handles method signature changes, class refactoring, assertion updates, and mock modifications.TestingNo warnings★ 258↓ —
- scenario-generatorArabelaTso/Skills-4-SEGenerate comprehensive test scenarios, user stories, and acceptance criteria from requirements and specifications. Use this skill when planning testing efforts, writing user stories, creating test cases, documenting acceptance criteria, exploring edge cases, designing test coverage, or translating requirements into actionable scenarios. Supports BDD (Given-When-Then), Gherkin syntax, user story format, and test case documentation.TestingNo warnings★ 258↓ —
- edge-case-generatorArabelaTso/Skills-4-SEAutomatically identify potential boundary and exception cases from requirements, specifications, or existing code, and generate comprehensive test cases targeting boundary conditions, edge cases, and uncommon scenarios. Use this skill when analyzing programs, code repositories, functions, or APIs to discover and test corner cases, null handling, overflow conditions, empty inputs, concurrent access patterns, and other exceptional scenarios that are often missed in standard testing.TestingNo warnings★ 258↓ —
- unit-test-generatorArabelaTso/Skills-4-SEAutomatically generates comprehensive unit tests for functions, classes, and modules. Use when you need to create tests for Python (pytest, unittest) or Java (JUnit, TestNG) code. Generates tests with comprehensive coverage including happy paths, edge cases, and error conditions. Analyzes existing test patterns in the codebase to match style and conventions. Supports mocking, parameterized tests, fixtures, and follows best practices for each framework.TestingNo warnings★ 258↓ —
- assertion-synthesizerArabelaTso/Skills-4-SEGenerate test assertions from existing code implementation. Use when the user has implementation code without tests or incomplete test coverage, and needs assertions synthesized by analyzing the code's behavior, inputs, outputs, and state changes.

- playwright-automationArabelaTso/Skills-4-SEBrowser automation via Playwright for web testing, screenshots, form filling, scraping, and verification. Use when tasks require navigating websites, interacting with web pages, or testing web applications.TestingNo warnings★ 258↓ —
- test-oracle-generatorArabelaTso/Skills-4-SEGenerates automated test oracles to verify correct software behavior. Creates assertion-based oracles (expected values), property-based oracles (invariants), differential oracles (comparing implementations), and metamorphic oracles (input transformations). Use when you need to generate assertions for test cases, identify invariants that should always hold, compare new vs legacy implementations, create metamorphic test relationships, validate function correctness, or improve test coverage with better verification strategies. Supports Python (pytest, unittest, hypothesis) and Java (JUnit, property testing).TestingNo warnings★ 258↓ —

Automatically identifies dependencies to mock and creates executable, maintainable test code.TestingNo warnings★ 258↓ —
- test-driven-generationArabelaTso/Skills-4-SEGenerate implementation code that passes existing unit tests.
