FastMCP Python framework for MCP servers with tools, resources, storage backends (memory/disk/Redis/DynamoDB). Use for Claude tool exposure, OAuth Proxy, cloud deployment, or encountering storage, lifespan, middleware, circular import, async errors.
Zustand state management for React with TypeScript. Use for global state, Redux/Context API migration, localStorage persistence, slices pattern, devtools, Next.js SSR, or encountering hydration errors, TypeScript inference issues, persist middleware problems, infinite render loops.
Cloudflare Workers KV global key-value storage. Use for namespaces, caching, TTL, or encountering KV_ERROR, 429 rate limits, consistency issues.
TanStack AI (alpha) provider-agnostic type-safe chat with streaming for OpenAI, Anthropic, Gemini, Ollama. Use for chat APIs, React/Solid frontends with useChat/ChatClient, isomorphic tools, tool approval flows, agent loops, multimodal inputs, or troubleshooting streaming and tool definitions.
Cloudflare Workers Runtime APIs including Fetch, Streams, Crypto, Cache, WebSockets, and Encoding. Use for HTTP requests, streaming, encryption, caching, real-time connections, or encountering API compatibility, response handling, stream processing errors.
Cloudflare Workflows for durable long-running execution. Use for multi-step workflows, retries, state persistence, or encountering NonRetryableError, execution failed errors.
This skill should be used when the user asks to "upload images to Cloudflare", "implement direct creator upload", "configure image transformations", "optimize WebP/AVIF", "create image variants", "generate signed URLs", "add image watermarks", "integrate with Next.js/Remix", "configure webhooks", "debug CORS errors", "troubleshoot error 5408/9401-9413", or "build responsive images with Cloudflare Images API".
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.
Convert video clips to optimized GIFs with speed control, cropping, text overlays, and file size optimization. Create perfect GIFs for social media, documentation, and presentations.
Extract transcript or subtitles from a local video file. Use this skill whenever the user asks to transcribe a video, extract speech-to-text, get subtitles, or wants a text version of what's said in a video. Also trigger on "提取字幕", "视频转文字", "语音转文字", "transcribe", "extract audio text", or when the user references getting a script/transcript from any video file (mp4, mkv, mov, avi, webm). This skill is for LOCAL video files — for YouTube or other online URLs, use the download-video skill first to get the file, then transcribe it.
Principle-engineering posture for production-grade code: reads the repo first, plans before code, matches conventions, pulls latest docs over training recall, and ships the simplest correct change that holds the bar — proper algorithms and data structures, idempotent writes, schema+queries+indexes as one artefact, typed errors, tests in the same diff. Substrate-agnostic; defers to peer skills on their lanes. Use for non-trivial planning, design, implementation, review, or refactoring; RCA and debugging; performance and optimization work; changes touching a database schema, security, infrastructure, or a public API; hardening inherited, vibe-coded, or LLM-generated code (dependency/CVE and migration audits); and over-engineering cleanup ("simplest solution," "YAGNI," "what can we delete").
The full checklist for keeping several accounts you own or are authorized to run from being correlated into one operator - profile, cookies, exit IP, timezone, WebRTC, account metadata, payment instrument, behaviour - not just the browser fingerprint. Use when someone runs multiple social / marketplace / ad accounts from one machine and wants to know what actually ties them together, why an isolation setup failed even though the fingerprint tested clean, how to pair one sticky proxy per account, how to verify a profile before trusting it (CreepJS, whoer, browserleaks WebRTC, pixelscan, liarjs), or which layers no browser can fix - shared recovery email, shared payout account, identical posting cadence. Also for 'account association', 'accounts got linked', 'multi-account setup', 'one proxy per account', 'profile isolation checklist', '账号关联', '防关联', '多账号运营'. The browser layer is implemented by the anti-detect-browser skill; MCP control is browser-mcp-agent.
