Notes

Fetch any URL and convert to markdown using baoyu-fetch CLI (Chrome CDP with site-specific adapters). Built-in adapters for X/Twitter, YouTube transcripts, Hacker News threads, and generic pages via Defuddle. Handles login/CAPTCHA via interaction wait modes. Use when user wants to save a webpage as markdown.

E2E testing for local web applications — constraint-first, execution-driven structure: iron rules, 5-stage execution flow with inline principles, artifact specification. Use this skill whenever the user wants to test a local web app, validate UI behavior, walk through multi-step user flows, mock API responses for testing, debug E2E test failures, capture screenshots, or understand E2E testing best practices. Triggers on: "test this web app", "E2E test", "UI test", "browser test", "验证 UI", "测试页面", "写个测试", "mock API", "端到端测试", "自动化测试", "帮我测一下", "test the login", "checkout flow", "registration flow", "dashboard test", or any mention of localhost testing, form validation, flow verification, or E2E debugging.

Generate and maintain business knowledge documents from codebase. Supports ingest (create/update docs) and lint (detect inconsistency and fix) operations. Triggers: 业务知识地图、生成业务文档、ingest domain knowledge、lint 业务知识、docify.

从原始需求素材（PRD、会议纪要、设计文档等）提炼结构化开发需求文档。通过三层模板（意图层/边界层/关联层）和五条逻辑校验规则，生成逻辑自洽的需求文档，暴露缺失和矛盾。触发词："提炼需求"、"结构化需求"、"需求文档"、"需求整理"、"refine requirement"。适用于 AI Coding Agent 开发前的需求整理，也适用于人类开发者审查和完善需求。

E2E testing methodology for local web applications — 21 principles across 5 domains (testing philosophy, data & mock, UI interaction, diagnosis & debugging, reporting). Pure methodology: no tool commands, no project conventions — teaches the agent how to think, not what to do. Use this skill whenever the user wants to test a local web app, validate UI behavior, walk through multi-step user flows, mock API responses for testing, debug E2E test failures, capture screenshots, or understand E2E testing best practices. Triggers on: "test this web app", "E2E test", "UI test", "browser test", "验证 UI", "测试页面", "写个测试", "mock API", "端到端测试", "自动化测试", "帮我测一下", "test the login", "checkout flow", "registration flow", "dashboard test", or any mention of localhost testing, form validation, flow verification, or E2E debugging.

高质量知识写作技能，创作精炼优雅，图文并茂的 Markdown 学习文章。 **当用户想要学习、研究或理解任何主题时，始终使用此技能。** 作为经验丰富的知识写作者—— 深度研究材料，识别核心概念与关系，撰写简洁、精准、有洞见的文章。 触发语（中文）："帮我学习 X"、"我想了解 X"、"研究 X"、"学习这个"、"总结"、"解释 X"、"消化这个"、"帮我深入理解" 触发语（英文）："help me learn"、"I want to understand"、"study this"、"summarize"、"teach me about" 特点：Markdown 输出配优雅图表（Mermaid/SVG/ASCII），自适应主题结构，高层写作原则， 视觉风格预览选择，内置去 AI 味处理，支持中英文输出。

为任何项目（前端或后端）生成专业测试策略和高质量测试代码。当用户描述功能、UI、验收标准，或要求编写测试、创建测试用例、添加测试覆盖、验证功能时，使用此技能。当用户分享需求并希望通过测试验证，或粘贴代码问'该如何测试'时，也触发此技能。即使用户未明确说'测试'，只要意图明显是验证行为或质量保障，就应使用此技能。

Comprehensive E2E testing for local web applications. Supports both agent-browser CLI (simple linear flows) and Playwright Python scripts (complex multi-step flows with API mocking, HTML interception, and programmatic control). Use this skill whenever you need to test flows on localhost, validate UI behavior, walk through multi-step scenarios, capture screenshots, or verify end-to-end functionality. Triggers on: test this web app, E2E test, UI test, browser test, 验证 UI, 测试页面, walk through, check that, verify the, test the login/checkout/registration/dashboard, or any request involving localhost testing, form submission, flow validation, or screenshot capture.
