🧪 Testing

Autonomous quality engineering swarm that forges production-ready code through continuous behavioral verification, exhaustive E2E testing, and self-healing fix loops. Combines DDD+ADR+TDD methodology with BDD/Gherkin specifications, 7 quality gates, defect prediction, chaos testing, and cross-context dependency awareness. Architecture-agnostic - works with monoliths, microservices, modular monoliths, and any bounded-context topology.

Read code to identify edge cases, write tests that cover those edge cases, and fix the implementation if tests expose failures. Use when a user asks to add edge-case tests, harden behavior, or validate that existing code handles unusual inputs or error paths (e.g., empty data, nulls, boundaries, invalid formats, timeouts, retries).

系統化除錯流程：根據使用者描述推定最可能的錯誤原因，對相關程式碼加入額外日誌，提供使用者重現步驟並請其回報日誌，依日誌修復並反覆確認直到問題解決，最後移除所有額外日誌。用於需要迭代式除錯與使用者回報日誌的情境。

Modular security expert workflow for evidence-first red-team audits with two execution modes: default interaction mode and user-requested auto mode. Use when users ask to find exploitable vulnerabilities, prove exploitability with reproducible evidence, implement minimal safe fixes, and add failing-then-passing security regression tests. Includes modules for agent systems and financial programs.

Clerk authentication integration for Astro/Next.js. Use when implementing authentication, handling Clerk middleware, testing with Playwright, or debugging auth issues. Trigger phrases include "Clerk auth", "sign in", "authentication", "middleware", "E2E testing with Clerk".

Build production-ready MCP servers using FastMCP framework with proven patterns for tools, resources, prompts, OAuth authentication, and comprehensive testing. Use this when creating FastMCP-based MCP servers with features like Google OAuth, multiple resource types, testing with FastMCP Client, or complex tool implementations.

Test and evaluate skill projects during development. Use when the user wants to test, evaluate, or assess a skill that is currently being developed in the workspace — i.e., the skill project in the current directory or a specified skill folder. This skill generates test cases, executes them against the target skill, and produces an evaluation report with strengths, weaknesses, and optimization suggestions. Triggers on requests like "test this skill", "evaluate my skill", "run skill tests", "assess skill quality", or "check if my skill works".
