dev-standards
プロジェクトの開発ルール遵守をチェックし、違反を報告・修正する。TypeScriptでのany禁止、CI品質チェック必須、ローカル動作確認、conventional commit採用、依存バージョン固定、ユニットテスト必須、コミット前lint/format/test実行のルールを適用。コード作成・編集後、コミット前、PRレビュー時に使用。`/dev-standards`で明示的にチェック、`--fix`で自動修正を実行。

Comprehensive quality validation for TypeScript/JavaScript projects - runs TypeScript checks, tests, coverage analysis, build validation, and linting with structured JSON results
TypeScript language rules with strict mode, testing, linting, and CI/CD best practices
Generate Jest unit tests, integration tests, React Testing Library component tests, mock implementations, test fixtures, and edge case coverage for TypeScript codebases
Fast unit testing framework for TypeScript/JavaScript. Use for testing tRPC procedures, Zod schemas, utility functions, and any TypeScript code. Built on Vite with native ESM, TypeScript support, and Jest-compatible API. Choose Vitest over Jest for modern TypeScript projects, especially with Vite-based setups.
Execute comprehensive test suite with validation, coverage reporting, and failure analysis. Works with any TypeScript/JavaScript testing framework (Jest, Vitest, Mocha, etc.). Returns structured output with pass/fail status, coverage metrics, and detailed error analysis.
TypeScript/JavaScript testing practices with Bun's test runner. Activate when working with bun test, .test.ts, .test.js, .spec.ts, .spec.js, testing TypeScript/JavaScript, bunfig.toml, testing configuration, or test-related tasks in Bun projects.
Jest、Vitest、Testing Libraryを使用した包括的なテスト戦略を実装し、モッキング、フィクスチャ、テスト駆動開発を用いたユニットテスト、統合テスト、エンドツーエンドテストを行います。JavaScript/TypeScriptテストの作成、テストインフラの設定、TDD/BDDワークフローの実装時に使用してください。
TypeScript/JavaScript project workflow guidelines using Bun package manager. Triggers on `.ts`, `.tsx`, `bun`, `package.json`, TypeScript. Covers bun run, bun install, bun add, tsconfig.json patterns, ESM/CommonJS modules, type safety, Biome formatting, naming conventions (PascalCase, camelCase, UPPER_SNAKE_CASE), project structure, error handling, environment variables, async patterns, and code quality tools. Activate when working with TypeScript files (.ts, .tsx), JavaScript files (.js, .jsx), Bun projects, tsconfig.json, package.json, bun.lock, or Bun-specific tooling.
JavaScript/TypeScript static analysis tool for call graphs, unused code detection (tree shaking), dependency analysis, and circular dependency detection
JavaScript coding standards and best practices for JavaScript and TypeScript. Use when writing or reviewing JavaScript code, working with promises, or discussing JavaScript patterns.
For token distribution on Solana 5000x cheaper than SPL (rewards, airdrops, depins, ...). @lightprotocol/compressed-token (TypeScript). Reference examples for custom claim support.
TypeScript SDK for MPC wallet integration across 36+ blockchains. Create wallets, import from seedphrase, sign transactions, execute swaps, scan for security threats, and more. Supports Bitcoin, Ethereum, Solana, and 33+ other chains with threshold signing security.
Audit TypeScript code for security vulnerabilities — hardcoded secrets, injection risks, missing input validation at trust boundaries, insecure defaults, auth gaps, sensitive data exposure, and unsafe patterns like eval or innerHTML. Use when: reviewing TypeScript code before deployment, auditing trust boundaries, preparing for a security review, onboarding third-party integrations, or hardening an application.
Reliability-first TypeScript skill for implementing, refactoring, or reviewing .ts code in shared libraries, services, browser code, and cross-layer contracts. Use when work needs strict tsconfig guardrails, schema-first parsing, unknown-at-boundary handling, discriminated unions, persistence/version safety, explicit async cancellation, or behavior-first testing.
Reliability-first backend TypeScript skill for APIs, workers, queues, CLIs, and long-running services. Use when writing Node, Bun, Deno, or worker code that needs request and env parsing, branded identifiers, explicit result errors, cancellation propagation, idempotent writes, persistence evolution, or contract and integration tests.
Generates production-ready BAML applications from natural language requirements. Creates complete type definitions, functions, clients, tests, and framework integrations for data extraction, classification, RAG, and agent workflows. Queries official BoundaryML repositories via MCP for real-time patterns. Supports multimodal inputs (images, audio), 6 programming languages (Python, TypeScript, Ruby, Java, Go, C#), 10+ frameworks, 50-70% token optimization, and 95%+ compilation success.
This skill should be used when developing applications with the Claude Agent SDK, answering questions about SDK features and APIs, implementing SDK patterns, or troubleshooting SDK integration. Covers Python and TypeScript APIs, core features, advanced features, and integrations.
