9-command agent skill suite for Tongji Look (look.tongji.edu.cn): setup, list, transcribe, take notes, manage materials, build course wiki, create cheat sheets, batch-process entire courses, and deploy course wiki to GitHub Pages.
Deploy the built course wiki site/ to GitHub Pages via gh CLI. Pre-checks gh auth status and site/ existence.
为非多模态模型（如 deepseek-v4-pro、GLM-5.1、mimo-v2.5-pro 等纯文本模型）提供图片识别能力。当主模型无法识别图片、用户发送了截图/设计稿/UI 截图需要分析、或者用户说'看看这张图'、'分析这个截图'、'这张图片有什么问题'时，自动触发此技能。也适用于用户粘贴了图片但当前模型不支持图片输入的任何场景。支持同时识别多张图片，通过配置多个识图模型实现主备回退。使用指令 /skill:vision-support 或 /vision 也可手动触发。铁律：本技能配置的模型仅用于图片内容识别，绝不参与主逻辑推理。注意：如果当前模型本身是多模态模型（如 Claude Sonnet 4、GPT-4o、Gemini 等可以直接识图的模型），不要使用此技能，直接让主模型识别即可。
Transcribe a single Tongji Look lecture video to SRT + TXT, optionally download slide snapshots in parallel.

Expert sales council with 6 advisors (Cialdini, Hormozi, Rackham, Voss, Klaff, Schwartz) for pricing, persuasion, negotiation, copywriting, and pitch strategies.
Operate Milvus vector database with pymilvus Python SDK. Use when the user wants to connect to Milvus, create collections, insert vectors, perform similarity search, hybrid search, full-text search, manage indexes, partitions, databases, or RBAC via Python code.
>- Audit and safely clean Xcode-related developer storage on macOS. Use whenever a developer mentions low disk space, Xcode storage, DerivedData, simulator devices or runtimes, stale beta platforms in Xcode Settings, DeviceSupport, archives, dSYMs, CocoaPods caches, simulator dyld caches, project .build folders, downloaded Xcode DMGs/XIPs, duplicate Xcode installers, or old Xcode applications. Also use this skill proactively when you hit low storage during other work, such as a build, download, or install failing with an out-of-disk-space error. Always measure first, report recoverable GiB with evidence, and obtain explicit itemized approval before any mutation.
Analyze web traffic, SEO performance, and search engine trends using Google Search Console, Google Analytics 4, and Bing Webmaster Tools. Use when the user asks to analyze traffic, check SEO, or find keyword opportunities.
Visualize business domains as standalone HTML + inline-SVG artifacts using an opinionated editorial design system. Ships six domain-modelling types — Aggregate, Context Map, Event Storm, Context Canvas, Ubiquitous Language glossary, and Domain Model — for exploring DDD designs with stakeholders, capturing decisions from event-storming sessions, or documenting a bounded context in a repo. Use this skill whenever the user wants to sketch, explore, or document a business domain — triggered by mentions of DDD, domain-driven design, bounded contexts, aggregates, event storming, ubiquitous language, context mapping, or any request to "visualize the domain", "draw the model", "map the contexts", "show the aggregate", or "help me think through the business". Shares a skinnable style guide with diagram-design so technical and domain diagrams produced for the same project look like siblings.
