Angular 21+ testing infrastructure with fixtures, ng-mocks, component harness, AAA pattern, and Jest best practices for eliminating duplication

How tests should be structured, named, and prioritized in this codebase.

Implement fixes for specific CodeRabbit review issues. Runs in isolated subagent context with focused task. Verifies fixes with tests before returning. Use one per issue from triage task list.

Manages local web server lifecycle and enables web page development with Playwright MCP. Use when developing HTML/CSS/JS, building web pages, viewing web pages, testing UI interactions, verifying renders, debugging frontend issues, or iterating on web design. Covers build, startup, shutdown, and browser-based testing workflows.

Build production-ready Opal IGA custom connectors with proper authentication, API compliance, security, and testing. Use when generating, auditing, or refactoring Opal connectors.

This skill should be used after creating or modifying test code to deeply analyze test structure, ensure enterprise-readiness, detect fake success patterns, and verify tests provide real value - validates against integration testing best practices to prevent tests that pass when implementation is broken

Systematic refactoring workflow - use coverage/complexity tools to identify targets, plan issues, execute with tests

Guides systematic implementation of new sustainability metrics in OSS Sustain Guard using the plugin-based metric system. Use when adding metric functions to evaluate project health aspects like issue responsiveness, test coverage, or security response time.

Use 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 loopholes

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.

Execute complete build pipeline with dead code detection, formatting, linting, type checking, testing, and production build. Use when the user mentions building, running the full pipeline, checking code quality, or preparing for deployment. Auto-triggers on phrases like "build the project", "run all checks", "prepare for production", or "validate code quality".

Generates .stylelintrc configuration for linting CSS, SCSS, and Vue component styles. Auto-detects stylesheet type and fetches latest package versions for plugins.

Build execution philosophy including TDD discipline, Minimal Intervention Principle, system awareness, and verification protocols. Use when implementing code, managing build phase, enforcing test-first practices, or preventing accumulative complexity. Triggers on: build phase, TDD, test first, red green refactor, minimal code, system awareness, implementation, code quality, verification protocols, build philosophy.

Use this skill when writing Go code following the Uber Go Style Guide. Provides comprehensive guidance on idiomatic Go patterns, error handling, concurrency safety, performance optimization, and test-driven development. Covers all critical Uber Go rules including channel sizing, goroutine management, interface design, and proper error handling. Appropriate for any task involving .go files, Go code reviews, refactoring, or implementing Go best practices.

Safe code refactoring with DDD patterns and test preservation

Production-tested setup for Zustand state management in React applications with TypeScript.This skill provides comprehensive patterns for building scalable, type-safe global state.Use when: setting up global state in React, migrating from Redux or Context API, implementingstate persistence with localStorage, configuring TypeScript with Zustand, using slices patternfor modular stores, adding devtools middleware for debugging, handling Next.js SSR hydration,or encountering hydration errors, TypeScript inference issues, or persist middleware problems.Prevents 5 documented issues: Next.js hydration mismatches, TypeScript double parenthesessyntax errors, persist middleware export errors, infinite render loops, and slices patterntype inference failures.Keywords: zustand, state management, React state, TypeScript state, persist middleware,devtools, slices pattern, global state, React hooks, create store, useBoundStore,StateCreator, hydration error, text content mismatch, infinite render, localStorage,

PR 作成後に .github/workflows/ci.yml が失敗したときの対応手順。ローカルで pytest 全ケースを実行し、エラー有無で分岐。エラーがあれば修正して commit-push スキルでコミット・プッシュ、無ければ GitHub Actions のログを確認して原因を特定する。

Senior ISMS Audit Expert for internal and external information security management system auditing. Provides ISO 27001 audit expertise, security audit program management, security control assessment, and compliance verification. Use for ISMS internal auditing, external audit preparation, security control testing, and ISO 27001 certification support.
