Entry point for Alibaba Cloud Bailian Sandbox instance and template lifecycle management: use `bl sandbox` when the user wants to create, query, connect, pause, resume, or release a Bailian sandbox, or view built-in base images, upload template mounted files, create, update, query, delete sandbox templates, or check template build status. When the user wants to access a created instance, open WebShell, or connect browser-use browser automation or a VNC live view, first get the connection information, then connect to the data plane. Not for host-execution sandbox setup, E2B official cloud resources, or general file transfer. agents.yaml hosted Agent / Session / Environment management is handled by bailian-managed-agent. Official install: `bl skill init` (installed together with the shared protocol bailian-protocol).
Elite frontend image-direction skill for generating premium, conversion-aware website design references. CRITICAL OUTPUT RULE — generate ONE separate horizontal image FOR EVERY section. A landing page with 8 sections produces 8 images. Never compress multiple sections into one image. Enforces composition variety (not always left-text / right-image), background-image freedom, varied CTAs, varied hero scales (giant / mid / mini minimalist), narrative concept spine, second-read moments, and a single consistent palette across all images. Optimized for landing pages, marketing sites, and product comps that developers or coding models can accurately recreate.
Turn papers, technical articles, or knowledge content into highly realistic AIGC slides. First create the narrative structure and direct the visuals page by page, then call an image generation model to generate each 16:9 slide image, and finally combine them into PPTX/PDF. Suitable for paper presentations, lab meetings, public lectures, technical talks, and commercial research presentations; use when the user mentions “paper PPT”, “AI-generated PPT”, “PPT that doesn’t look AI-generated”, “high-quality slides”, or “page-by-page image generation PPT”.
Use when creating game art through Scenario MCP: sprites, sprite sheets, icons, props, loot, tilesets and autotile terrain transitions, seamless tiles, isometric buildings, top-down maps, pixel art, UI buttons and panels, parallax background layers or depth planes for side-scrollers, and character or concept art; or when assets need transparent backgrounds, background removal, style-consistent variation batches, upscaling, pixel-grid cleanup, or PNG export for Unity, Godot, or Unreal.
The idea-system craft — never run out of content ideas by running a system instead of waiting for inspiration. Use when someone is out of ideas, stares at a blank calendar, asks where good ideas come from, wants an idea bank/backlog, feels their AI-generated ideas sound like everyone else's, or thinks their niche is "boring." Uses the SPARK framework. Reads brand-profile + social-strategy + content-pillars + audience-research first. The audience is the idea engine (comments/DMs/FAQs clustered into themes); AI expands real signals, it doesn't discover them; systems beat muses; trends are a timing filter, not a source. The agent clusters/expands/scores; the HUMAN supplies proprietary signals and decides; WoopSocial publishes the content, not ideas. Never rewords competitor posts, invents audience questions, or fabricates probe results. Distinct from social-strategy/content-pillars, audience-research, cross-platform-repurposing/ content-recycling, and the format skills
Use when generating or reviewing NetSuite SDF permission configurations such as customrole XML, script deployment permissions, permkey values, permlevel choices, run-as role design, and least-privilege access. Confirms exact ADMI_ / LIST_ / REGT_ / REPO_ / TRAN_ permission IDs, distinguishes standard permissions from customrecord_* script IDs, and validates permissions against bundled NetSuite reference data.
Commit, push, branch, and manage version control with GitButler. Use for commits, selective dirty-file or hunk commits, branches, diffs, PRs, history edits, squashes, amends, undo, merge, fetching, pulling and syncing a branch with its remote, apply, unapply, and linked worktrees. For selected dirty files or hunks, inspect with `but diff`; use compact `but status` for commit order, branch/stack placement, or conflict overview; use `but status -fv` when file IDs or per-commit file details matter. Replaces git write commands, including fetch and pull. Applies in every checkout of the repository, even when a plain branch is checked out, including linked worktrees such as `.claude/worktrees/*`, and to git writes made while testing or cleaning up (stash, checkout -- <file>, restore, reset)
Use this skill when using Arcade Physics in Phaser 4. Covers enabling physics, velocity, acceleration, gravity, collisions, overlap, world bounds, physics groups, static bodies, and collision categories. Triggers on: physics, arcade, velocity, gravity, collide, overlap, bounce, physics body.
Guide for creating AI subagents with isolated context for complex multi-step workflows. Use when users want to create a subagent, specialized agent, verifier, debugger, or orchestrator that requires isolated context and deep specialization. Works with any agent that supports subagent delegation. Triggers on "create subagent", "new agent", "specialized assistant", "create verifier". Do NOT use for Cursor-specific subagents (use cursor-subagent-creator instead).
Use when video content needs to be extracted as text: pasted YouTube links or IDs, requests to transcribe, summarize, quote, translate, convert video to text, or extract information from video content. Also use when a user shares a video URL without explanation and wants to know what it says. Not for uploads or account management.
Use this skill when creating, running, reattaching to, listing, stopping, or removing Docker Sandboxes (the standalone `sbx` CLI that runs AI coding agents in isolated microVMs), even if the user just says they want to "run claude in a sandbox", "isolate an agent from my repo", "give an agent its own git clone", or "clean up old sandboxes". Covers `sbx run`/`sbx create` (including the built-in agents claude, codex, cursor, devin, docker-agent, gemini, opencode, shell), workspace bind-mount vs `--clone` isolation, additional read-only workspaces, reattaching by `--name`, `sbx ls`/`stop`/`rm`/`prune`, `sbx exec`, `sbx cp`, and `sbx ports`.
AI citability scoring and optimization. Analyzes web page content to determine how likely AI systems (ChatGPT, Claude, Perplexity, Gemini) are to cite or quote passages from the page. Provides a citability score (0-100) with specific rewrite suggestions.
Designs custom laboratory hardware as parametric build123d models and exports fabrication artifacts as STEP, STL, and DXF files - microfluidic chips and molds, optomechanical mounts and breadboard adapters, cuvette and microplate holders, tube racks, animal-behavior rigs, and 3D-printed instrument fixtures. Use when a research task needs a physical part that must mate with standardized labware, an optical table, a cage system, or a printer, CNC, or laser process.
Operate a TreeSeed control plane through its current MCP capabilities for project, knowledge, governance, and execution work. Use when a task targets TreeSeed records or governed project-agent chat; do not use it as authority to run agents or mutate repositories.
Babysits an open GitHub PR until merge-ready, first judging whether an old PR still belongs. Use when asked to watch a PR over time or update an old one — not for one-shot comment resolution or one CI failure. GitHub (incl. Enterprise) only
New Zealand business English writing style for professional communications — warm, inclusive, EN-NZ spelling (colour, organise, centre). Use whenever the user is writing for a New Zealand audience: emails, chat messages, proposals, client communications, blog posts, web copy, or any business writing. Apply to drafting, editing, and tone-checking professional text.
Download video and audio from YouTube and 1000+ sites using yt-dlp. No API keys needed. Use when: (1) Downloading a video from YouTube or other sites, (2) Extracting audio from a video URL, (3) Downloading subtitles/captions from a video, (4) Getting video metadata without downloading.
Use this skill when configuring what a Docker Sandboxes (`sbx`) sandbox can reach on the network or which credentials it authenticates with, even if the user just says they want to "let the agent call an internal API", "block all network access", "give the agent a GitHub token", or "use a private registry image for a sandbox". Covers `sbx policy init/allow/deny/ls/inspect/log/check/rm network` (global and per-sandbox egress rules, deny-over-allow precedence) and `sbx secret set/set-custom/ls/rm/import` (service secrets, dynamic secrets via --ref/--command, and registry pull credentials with their host-pulls-only-by-default injection scope).
Clone a section, widget, page or animation from any reference (a live website URL, a screen recording, an mp4/mov/webm, a gif, a Lottie file, a prototype export) frame by frame into the user's own codebase, then record the clone and verify it against the reference frame by frame, iterating until timing, easing, sequence and layout match. Use whenever the user wants to clone, copy, replicate, recreate, reverse-engineer, port or "steal" a hero, section, widget, marquee, carousel, hover effect, page transition, loader, scroll animation or interaction from a site or video, says "make it look/feel/move like this", "same animation as", "match this exactly", or hands over a gif/video and asks to build it, including when they also want to add their own content, colours or extra features on top, or only want part of the reference (one section, one widget, a few seconds). Covers canvas, WebGL, WebGPU and three.js / 3D scenes (shaders, particles, globes, glTF models) as well as CSS and JS motion. Pixel-level matching of fonts, colours and spacing is done only when they ask for it.
Expert-level implementation assistant for the Universal Commerce Protocol (UCP). Provides comprehensive tooling for adding UCP support to Next.js ecommerce codebases — from initial consultation through full implementation, testing, and validation
AE Agent platform CLI for Agent, resource package import and export, notification, approval, archived conversation, model, MCP, Skill, attachment, and user-memory work. Use when managing these resources, browsing Agent markets, handling approval requests and tasks, restoring archived conversations, persisting user memory, or answering from user preferences, background, stable workflows, or historical conventions
Comprehensive design system guidelines for building consistent, accessible, and scalable component libraries. Use when creating design tokens, building component libraries, implementing design systems, setting up theming architecture, or establishing UI governance processes.
Use for NVIDIA-related requests where an NVIDIA skill might help, even if the user did not ask for a skill. Trigger on NVIDIA products, hardware, software, SDKs, GPUs, Jetson/JetPack/L4T/BSP/SDK Manager/driver/flashing/setup, CUDA, NIM, NeMo, Omniverse/OpenUSD/SimReady, Isaac, RAPIDS/cuDF, cuPyNumeric, cuOpt, Dynamo, Holoscan, TensorRT, DeepStream, VSS, TAO, NGC/NVCF. Do not use for generic non-NVIDIA route, optimize, deploy, AI, video, data, or infrastructure tasks.
Generate storyboard image boards and matching video-generation prompt scripts for specific scenes in a short video plan. Use this skill whenever the user asks to create a storyboard, storyboard image, video prompt script, scene prompt, image-to-video prompt, shot board, or per-scene video-generation package, especially when they specify a scene number, duration, or an existing video plan. This skill saves outputs as storyboard/scene-XX.png and storyboard/scene-XX.md and enforces grid sizing, timing labels, and strict character, wardrobe, prop, and location continuity.
AE knowledge base CLI manual for creating, importing read-only compiled snapshots, querying, LLM-powered ask, listing accessible knowledge bases and their sources, deterministic index/grep/read retrieval, checking status, ZIP source upload and directory management, raw child-file reading, revision-checked child updates and deletion, compiling, schema generation, URL sources, source deletion, ordinary text source creation, full reads and revision-checked editing, file/ZIP source draft replacement and restoration, and knowledge base deletion. Use when the user asks to manage AE (Agentic Engine) knowledge bases, import a compiled Markdown ZIP snapshot, upload documents or URLs to a knowledge base, query knowledge, ask knowledge bases with an LLM, list accessible knowledge bases or source metadata, inspect knowledge base indexes, search knowledge base pages, read a specific knowledge base page, check knowledge base status, generate schemas, compile knowledge, remove sources, create or edit text sources, or delete a knowledge base. To choose which knowledge base is worth searching, use the ae-kb-discovery skill first; this skill runs the retrieval once a target is chosen. Must use ae-cli kb commands and must not guess knowledge base names, scopes, page paths, source IDs, source display names, JSON payload shapes, or URL formats.
Prepare, publish, resume, and verify private iOS release-testing installs with asc distribute. Use when distributing an IPA to registered devices outside TestFlight, reconciling ad hoc profiles, publishing through caller-owned S3-compatible storage, or diagnosing a resumable private distribution run.
Check whether newly merged CLI features in te-cli are sound. Scans six dimensions — command registration, business domain ↔ skill pairing, skill documentation coverage, internal consistency of skills, user documentation sync, and engineering robustness — to find problems such as commands failing to load, AI agents reading empty docs and guessing parameters, or outdated user documentation. Use when a new command domain/command is merged, a skill is added or modified, a pre-release self-check is needed, or CLI feature completeness must be assessed.
Find and fix application security problems: security reviews, CVE remediation, hardening, secrets and auth, SOC 2, PCI-DSS, HIPAA and GDPR checks. Use whenever the user asks if their app is secure, needs to patch a vulnerable dependency or prepares for an audit.
Build browser or server USDC bridging with Circle App Kit or standalone Bridge Kit and CCTP. Supports EVM and Solana browser wallets, private-key and Circle Wallets adapters, bridge events, custom fees, transfer speed, Forwarding Service, and recovery. Bridge operations require no kit key. Use when: bridging USDC, moving USDC across chains, building wallet-connected bridge UIs, configuring Viem/Ethers/Solana adapters, or using @circle-fin/bridge-kit, @circle-fin/app-kit, CCTP, forwarding, or bridge routes.
Documents edge cases, error states, boundary conditions, race conditions, and recovery paths for a feature - the systematic catalog of what can go wrong and the failure modes to design for. Use during specification to map the failure surface and ensure comprehensive coverage, or during QA planning to identify boundary and limit scenarios to test. Distinct from deliver-acceptance-criteria, which writes story-level Given/When/Then checks; this skill produces the whole-feature edge-case catalog.
Discovers trending and viral YouTube videos by category and country using apidojo's YouTube Trending Scraper on Apify. Triggers when the user asks to: find viral YouTube videos today, discover what's trending on YouTube in a specific country, get trending gaming or music videos on YouTube, find top YouTube videos this week by category, identify viral content on YouTube for inspiration, research what topics are dominating YouTube trending, or track trending YouTube content for content strategy. Returns video title, views, likes, channel info, duration, keywords, and thumbnail. Ideal for content strategists, YouTubers, and trend researchers.
Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. When Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks
Build React UIs with Fluid Functionalism — a shadcn/ui registry (@fluid) of animated components with a shared motion system: three spring speeds, a hover highlight that glides from item to item under the cursor, and labels that change weight without layout shift. Use whenever the user mentions Fluid Functionalism, @fluid, or fluidfunctionalism.com; asks for UI with satisfying, fluid, polished motion in a React, Next.js, shadcn, Radix, or Base UI project; builds any interface (settings dialogs, sidebars, command menus, chat UIs, forms, lists, tables) in a project with @fluid components installed; asks to review or audit existing UI motion against the system; or asks to update installed @fluid components or what changed in a release. Also use before hand-writing animation code (hover highlights, icon swaps, weight changes, enter/exit transitions, page reveals, skeleton loading) there, so custom code follows the system instead of inventing timings. Bundled scripts read the stack fresh each run and write nothing.
Query TikTok e-commerce data (products, shops, creators, videos, livestreams, categories) via the KaloPilot AI agent. Use this skill whenever the user asks about TikTok Shop data, product rankings, creator performance, shop analytics, category trends, livestream metrics, or any TikTok e-commerce insight — even if they don't say "KaloPilot" explicitly. Also trigger when the user says "ask pilot", "check kalodata", or mentions TikTok sales/revenue data.
Platform specs and publish validation — per-platform requirements and the validate-before-publish step for multi-platform fan-out. Use when fanning a post out to multiple platforms, when a post is getting rejected, when mapping per-platform postType/required fields, or to run the validate-before-publish step. Encodes the per-platform postType enums, required-field matrices, and media rules from the OpenAPI spec, and runs POST /posts/validate so a post lands correctly on every target. Uses the CHECK framework. The keystone the per-platform format skills point to. WoopSocial validates + publishes atomically and has no update endpoint; the agent maps fields and fixes spec violations, but human-judgment calls (disclosure truthfulness, privacy intent) stay with the person; metrics never fabricated. Distinct from the per-platform format skills (one platform's content) and scheduling-and-queue (timing).
Battle-tested Playwright patterns for writing and debugging reliable E2E, API, component, visual, accessibility, and security tests. Use when you need locator strategy, assertions, fixtures, network mocking, auth flows, trace debugging, or framework recipes for React, Next.js, Vue, and Angular. TypeScript and JavaScript.
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.
