Script and automate repetitive tasks and workflows.
Generates unit tests for changed files and identifies coverage gaps. Use when the user asks to write tests, generate test suites, check coverage, or mentions Jest, Vitest, Playwright, or Mocha.
Generate comprehensive unit tests for iOS RxSwift project files (ViewModels, UseCases, Services). Creates complete test files with nested mocks, RxTest patterns, session error handling, and memory leak tests. Use when "generate unit tests", "write tests for", "create unit tests", "add tests for", or analyzing Swift files in PayooMerchant project.
Run tests with Jest, Vitest, or Playwright, fix failing tests, and generate missing test coverage. Use when user says "run tests", "test this", "fix failing tests", "write tests", or when tests need to be executed or created.
Automatically generates a Vitest unit test template for any new feature or component to protect existing code from being broken.
Use this skill when implementing any feature, bug fix, or plan task. Triggers on "write tests", "add a test", "do TDD", "test-driven", "implement with tests", "implement task", or when dispatched as a subagent for plan execution. Write test first, watch it fail, write minimal code to pass.
Guide for refactoring and improving existing test code, step definitions, and page objects. Use this when asked to improve code quality, maintainability, or performance.
Generate test files for new code including unit, integration, and e2e tests. Triggers: test, 產生測試, generate test, 測試, 寫測試.
Development hot reload behavior. Auto-triggered when discussing file watching, rebuilds, or dev server.
Writes Roc code with strong static types, helpful compiler errors, and functional programming. Use when the user wants Roc code, mentions Roc, functional programming with types, or needs .roc files. Covers both full applications and one-off Roc scripts with shebangs.
Validates Single Source of Truth (SSOT) documentation files for parity with code. Use when user asks about SSOT validation, architecture docs, or project truth sources.
Claude Codeのイベント駆動型自動化とバリデーション用のhooksを作成します。tool呼び出し、ユーザーメッセージ、コミット前チェックなどのイベントに反応するhooksを実装します。自動化ワークフロー、バリデーション、イベント駆動処理が必要な場合に使用してください。
Update Nix flake inputs in persops. Use when asked to update flake.lock/inputs, update AI inputs (codex-cli-nix, claude-code-nix, llm-agents), or run full `nix flake update`, then verify with `nix flake check` and commit the update-only changes.
Extract classes, functions, or code blocks from large modules into separate files. This skill should be used during refactoring to break up monolithic files while maintaining import compatibility and test coverage.
Reference for the @pierre/diffs code/file diff rendering library (React, vanilla JS, SSR, worker pool, caching). Use when you need API usage, setup, or configuration details for parsing diffs, rendering files, or tuning options.
Create or update a Makefile with dev and build targets that run the repo's actual development and build commands. Use when asked to standardize run/build commands or add Makefile targets.
Iterate on specs for better code generation. Use when Claude output needs refinement.
Find and delete unused files, disabled code blocks, Enhanced variants, deprecated features, test files in production for Leavn app
Update pkgsrc ChangeLog entries under config/pkgsrc/files/*/*/ChangeLog and keep Makefile version metadata in sync. Use when updating qrpc-devel or qrpc-prod ChangeLogs, updating their versions, or recording dependency changes.
Guide for using direnv - a shell extension for loading directory-specific environment variables. Use when setting up project environments, creating .envrc files, configuring per-project environment variables, integrating with Python/Node/Ruby/Go layouts, working with Nix flakes, or troubleshooting environment loading issues on macOS and Linux.
