Three.js lighting - light types, shadows, environment lighting. Use when adding lights, configuring shadows, setting up IBL, or optimizing lighting performance.

Three.js animation - keyframe animation, skeletal animation, morph targets, animation mixing. Use when animating objects, playing GLTF animations, creating procedural motion, or blending animations.

Optimize Apache Spark jobs with partitioning, caching, shuffle optimization, and memory tuning. Use when improving Spark performance, debugging slow jobs, or scaling data processing pipelines.

Use when implementing or debugging ANY network request, API call, or data fetching. Covers fetch API, React Query, SWR, error handling, caching, offline support, and Expo Router data loaders (useLoaderData).

Practical patterns for using fp-ts with React - hooks, state, forms, data fetching. Use when building React apps with functional programming patterns. Works with React 18/19, Next.js 14/15.

Quick reference for Option type. Use when user needs to handle nullable values, optional data, or wants to avoid null checks.

Quick reference for Either type. Use when user needs error handling, validation, or operations that can fail with typed errors.

Build apps with the Claude API or Anthropic SDK. TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`/`claude_agent_sdk`, or user asks to use Claude API, Anthropic SDKs, or Agent SDK. DO NOT TRIGGER when: code imports `openai`/other AI SDK, general programming, or ML/data-science tasks.

Azure Identity SDK for .NET. Authentication library for Azure SDK clients using Microsoft Entra ID. Use for DefaultAzureCredential, managed identity, service principals, and developer credentials.

Azure Cosmos DB SDK for Python (NoSQL API). Use for document CRUD, queries, containers, and globally distributed data.

Transform generated wiki Markdown files into a polished VitePress static site with dark theme and interactive Mermaid diagrams. Use when user asks to "build a site" or "package as VitePress", user runs the /deep-wiki, or user wants a browsable HTML output from generated wiki pages.

Publish and read business processes in UiPath Automation Hub via the Open API, using the user's cloud login — no admin OpenAPI token needed. PUBLISH an approved process and its PDD/SDD documents (schema-driven payload, base64 file upload or link) to AH as the system of record — e.g. a process captured/approved by Process Scribe. GET a process back by id or search, list its attached documents, and DOWNLOAD their file bytes (e.g. for dedup / related-idea lookups or retrieving a published PDD). Authenticates with the user's cloud bearer token and NEVER sends the admin `x-ah-openapi-auth` header. CLI-first: when the installed `uip` has the `ah` commands, flows run through them (`references/*-cli-guide.md`); otherwise the raw Open API flows apply. Routes by intent to publish (create/upload) or get (read/fetch/download) references over the shared catalogs. Structured to extend to more Automation Hub operations.
