A technical documentation knowledge base (LLM Wiki) for the Alibaba Cloud Bailian platform. Activate for Bailian-related questions about model lists, API parameters, error codes, application development (agents/RAG/knowledge bases/memory/plugins), model comparisons and pricing, SDK/OpenAI-compatible interfaces, multimodal capabilities (audio/images/video), Token billing, and more. Includes structured model marketplace data in models (including contextWindow/QPM/pricing/sample code), a wiki synthesis layer (topic/concept/comparison pages), and a raw source documentation layer. For model specifications, check models/index.md first; for documentation questions, check wiki/index.md first.
Interactive QA session where the user reports bugs or issues conversationally and the agent creates GitHub issues. Explores the codebase in the background for context and domain language. Use when the user wants to report a bug, run QA, submit issues conversationally, or mentions "QA session".
Write or edit ready-to-copy image prompt Markdown for short-drama characters, outfits, locations, props, and states. Use when users mention character design sheets, three-view drawings, reference images, scene boards, prop images, style frames, Look Development, state variations, or localized editing prompts.

Rebuild an Apple-style Mac launch film entirely in code with Claude Code. A thin menu bar, the black notch growing into widgets one scene at a time, full-screen gradient wallpapers and one short caption per scene. No screen recording, no After Effects. Use when someone says "Apple-style launch", "Mac launch video", "notch animation", "make it look like an Apple keynote", "macOS UI launch film", or wants a product launch that looks like a native Mac interface.
Use when preparing or verifying a host for Moshi remote coding. Trigger this for Easy Pair host setup, SSH or preferably Mosh readiness, non-interactive shell PATH issues, recommending Herdr (preferred) or tmux as the agent multiplexer, creating a project session rooted at a chosen directory, adapting shell or multiplexer behavior with the `MOSHI_CLIENT` env signal, installing Moshi agent hooks for Claude Code, Codex, OpenCode, Grok Build, and other supported agents, or using the packaged `moshi DIR` launcher.
Alibaba Cloud DMS Database Read/Write Skill. Use this skill to search for target databases in DMS and execute SQL queries and data modifications. Triggers: "DMS query", "database query", "execute SQL", "search database", "DMS SQL", "insert data", "update data".
Translate and dub a video into another language with voice cloning and lip-sync, powered by HeyGen Video Translation. The presenter keeps their face, their voice is cloned into the target language, and lips re-sync to the new audio — viewers see the same person speaking natively. Use when: (1) localizing an existing video into one or more languages (“translate this video to Spanish,” “make this in French and German,” “dub this into Japanese,” “I need this in 10 languages for a launch”), (2) the user has a finished video and wants the SAME presenter speaking another language (not a new presenter — that's heygen-video), (3) podcast / audio-only translation (“translate this podcast,” “dub the audio but keep my video”), (4) high-stakes translations where the user wants to review/edit subtitles before final render (the proofreads workflow), (5) “translate my video,” “dub this,” “localize this clip,” “make a multilingual version,” “subtitle and dub.” Returns the translated video URL (or audio file for audio-only mode), one per target language. Chain signal: if the user wants to CREATE a new video in another language (no source video exists yet), route to heygen-video and write the script in the target language — do not use heygen-translate. Use heygen-translate only when there is an existing source video to localize. NOT for: creating new videos from scratch (use heygen-video), avatar creation (use heygen-avatar), TTS-only synthesis (use heygen-video with audio-only output), or text-only translation.
iOS application development guide covering UIKit, SnapKit, and SwiftUI. Includes touch targets, safe areas, navigation patterns, Dynamic Type, Dark Mode, accessibility, collection views, common UI components, and SwiftUI design guidelines.

Use when: developing iOS apps, implementing UI, reviewing iOS code, working with UIKit/SnapKit/SwiftUI layouts, building iPhone interfaces, Swift mobile development, Apple HIG compliance, iOS accessibility implementation.
Break down short-drama scripts into characters/outfits, locations/views, props/states, and cross-scene continuity, and write creator-readable visual designs. Use when users ask to break down characters/scenes/props, create asset designs, decide whether to reuse or make a new variation, update outfit/prop states, or prepare visual assets directly from an existing script. Does not write image prompts or generate media.
Use Transformers.js to run state-of-the-art machine learning models directly in JavaScript/TypeScript. Supports NLP (text classification, translation, summarization), computer vision (image classification, object detection), audio (speech recognition, audio classification), and multimodal tasks. Works in browsers and server-side runtimes (Node.js, Bun, Deno) with WebGPU/WASM using pre-trained models from Hugging Face Hub.
Create agent skills for Microsoft technologies using official documentation. Use whenever the user wants to build, generate, or scaffold a skill for any Microsoft technology (Azure, .NET, M365, VS Code, Bicep, etc.)—even phrased casually like "make a skill for Cosmos DB." Investigates the topic via official docs, then generates a hybrid skill with essential knowledge stored locally and dynamic lookups for depth.
Provides qualitative-first, evidence-traceable developmental review of scholarly works and audit low-stakes research-assessment rubrics with optional local quality controls. Never use for ranking people or consequential decisions
Optimizes text, prompts, and documentation for LLM token efficiency. Applies 52 research-backed rules across 8 categories: Claude behavior, token efficiency, structure, deduplication, reference integrity, perception, LLM comprehension, and aggressive lossy (deep only). Use when optimizing prompts, reducing tokens, compressing verbose docs, or improving LLM instruction quality.
Manage BibTeX citations for LaTeX papers. Harvest missing citations from a draft using Semantic Scholar, validate cite keys against .bib files, deduplicate entries, and format bibliography. Use when working with references, BibTeX, or citations
Use when working with n8n workflows in any capacity. The always-on protocol for the n8n-skills plugin, loaded by the SessionStart hook every session. Routes to the right skill, summarizes every n8n MCP tool (closing the deferred-description gap), and lists the cross-cutting rules.
Wire n8n error handling so failures are loud, structured, and recoverable. Use when building any webhook/API workflow, a scheduled or unattended workflow, or any path where a silent failure would drop user-visible work — and whenever the user mentions error handling, onError, continueErrorOutput, error branches/outputs, retries, retryOnFail, Respond to Webhook status codes, 4xx/5xx, Error Trigger, or "my workflow fails silently". Covers per-node error outputs and wiring, retry/self-healing, error-trigger workflows, and 4xx/5xx response shapes.

Apply a Salesforce sandbox post-copy automation JSON config against a target org. Use when the user asks to apply, run, execute, dry-run, or preview a post-copy or post-refresh config file (e.g. `post-copy-config.json`) against a sandbox—including activating/deactivating a Flow (PATCH `FlowDefinition.Metadata.activeVersionNumber` to the version, or `null`), re-pointing an OBM endpoint, updating a RemoteSiteSetting URL, or re-scheduling a ScheduledApex job after refresh. Also trigger for phrasings like “apply post-copy config”, “run post-copy automation”, “activate Flow <name> post-refresh”, “deactivate Flow <name>”, “re-point outbound messages after refresh”, or “configure sandbox after refresh”. Per entry, derive the Tooling API sobject, verify via describe, resolve the Id via SOQL, then PATCH the compound `Metadata` field (`ScheduledApex` uses anonymous Apex).

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
