Use this skill to test suspend functions and coroutine-using classes on the JVM with kotlinx-coroutines-test. Covers runTest, TestScope, StandardTestDispatcher vs UnconfinedTestDispatcher, virtual time via TestCoroutineScheduler (advanceTimeBy, advanceUntilIdle, runCurrent), the canonical MainDispatcherRule wrapper for Dispatchers.setMain/resetMain, the TestResult Promise contract on KMP, and the runBlockingTest -> runTest migration. If the user mentions runTest, runBlockingTest deprecated, advanceUntilIdle, advanceTimeBy, TestScope, StandardTestDispatcher, UnconfinedTestDispatcher, MainDispatcherRule, "Module with the Main dispatcher is missing", "test hangs forever", dispatchTimeoutMs, viewModelScope test, or a ViewModel that posts state from a coroutine, use this skill.
AI trending-topic collector. Collects AI-related trending content from Twitter/X, Product Hunt, Reddit, Hacker News, blogs and more. Triggers when the user says "开始今日选题", "采集热点", "看看今天有什么新闻", "今日AI热点". Focus areas: Vibe Coding, Claude Skill, AI knowledge management, AI model updates, new AI products, overseas trends.
Retrieve and interpret an authorised owner's PetTracer collar inventory, latest known GPS fix, or bounded location history. Use for explicit PetTracer work, not generic pet questions or tracking a person. Distinguish measurement time, contact time, missing data, and stale fixes.
Deep reference for when the Motoko migration chain misbehaves — upgrade compatibility errors you cannot explain, migration files you cannot write, a first migration whose OldActor is non-empty, a project converted from legacy persistence, or a request to delete/remove the migrations directory or revert to inline (with migration = ...). Load only when the rules in migrating-motoko-actors do not explain what you are seeing.
TSDoc (TypeScript documentation comments) guidelines. @param, @returns, @example, @remarks, @public / @beta / @alpha / @internal, @packageDocumentation, @privateRemarks, {@inheritDoc}, @override, @deprecated, @see, @throws. TypeDoc-compatible, with standard TSDoc tags and TypeDoc extensions (@category, @since, linkcode, linkplain). Automatically referenced when writing or reviewing code.
Fetch Twitter/X post content by URL using jina.ai API to bypass JavaScript restrictions. Use when Claude needs to retrieve tweet content including author, timestamp, post text, images, and thread replies. Supports individual posts or batch fetching from x.com or twitter.com URLs.
Execute and analyze Unity Test Framework tests from the command line. This skill automates test execution for Unity projects by detecting the Unity Editor, configuring test parameters (EditMode/PlayMode), running tests via CLI, parsing XML results, and generating detailed failure reports. Use this when running Unity tests, validating game logic, or debugging test failures.
Prove whether a given directory, file, exported symbol, function, component, constant, hook, type, or helper has "no real consumers", then decide whether to delete it. Use for dead code cleanup, unused code detection, unused export audits, deletion safety checks, and consumer searches; it only answers questions of consumption relationships and deletion safety, not whether something that is still used is actually necessary - for that, use necessary-code-audit.
Use when coordinating subagents for coding, research, repair, or review work where delegated workers may drift, stall, crash, duplicate, or edit a shared workspace and the coordinator must preserve scope, verification, and user-consent boundaries.
Finds the carousels that actually went viral in your niche, fetches every slide, breaks down why each one worked, and builds your own carousel on that proven structure in your words and your design. Use when the user says "find viral carousels", "what carousels are working in my niche", "make a carousel like this one", "copy the structure of this carousel", or before posting any carousel.
ALWAYS use after design/implement for screenshot QA: capture, contrast, fix, document. Mandatory after handoff. Fast widths 375/768/1440; before flagship done use --preset done (375/430/768/1024/1440/1920). Auto-fix — never report-only unless user says audit-only. Edges must read on the plane.
Audit an existing VictoriaMetrics vmanomaly configuration against runtime capabilities and real data. Use when reviewing model-data fit, scheduler cadence, persisted-state compatibility, cold start, excessive detections, missing anomalies, output cardinality, or upgrade readiness. Trigger on vmanomaly config review, false-positive investigation, detection quality, model effectiveness, compatibility, and "is my anomaly detection working?" Use vmanomaly-config instead when building a new configuration from scratch.
Helps create vvvv gamma editor extensions — .HDE.vl file naming, Command node registration with keyboard shortcuts, SkiaWindow/SkiaWindowTopMost window types, docking with WindowFactory, and API access to hovered/selected nodes via VL.Lang Session nodes. Use when building editor plugins, custom tooling windows, or automating editor workflows.
Explains vvvv gamma core concepts — data types, frame-based execution model, pins, pads, links, node browser, live compilation (source project vs binary reference workflows), .vl document structure, file types (.vl/.sdsl/.cs/.csproj), ecosystem overview, and AppHost runtime detection. Use when the user asks about vvvv basics, how vvvv works, the live reload model, when to patch vs code, or needs an overview of the visual programming environment.
Helps write code using vvvv gamma's Spread<T> immutable collection type and SpreadBuilder<T>. Use when working with Spreads, SpreadBuilder, collections, arrays, iteration, mapping, filtering, zipping, accumulating, or converting between Span and Spread. Trigger whenever the user writes collection-processing C# code in vvvv — even if they say 'list', 'array', or 'IEnumerable' instead of Spread, this skill likely applies.
Tether Wallet Development Kit (WDK) for building non-custodial multi-chain wallets. Use when working with @tetherto/wdk-core, wallet modules (wdk-wallet-btc, wdk-wallet-evm, wdk-wallet-evm-erc-4337, wdk-wallet-solana, wdk-wallet-spark, wdk-wallet-ton, wdk-wallet-tron, ton-gasless, tron-gasfree), and protocol modules including swap (wdk-protocol-swap-velora-evm, bridge (wdk-protocol-bridge-usdt0-evm), lending (wdk-protocol-lending-aave-evm), and fiat (wdk-protocol-fiat-moonpay). Covers wallet creation, transactions, token transfers, DEX swaps, cross-chain bridges, DeFi lending/borrowing, and fiat on/off ramps.
Build and deploy web apps to the cloud. Supports React, Vue, Astro, Next.js (static), vanilla HTML/CSS/JS, and serverless functions. Sites deploy to *.rebyte.pro with automatic SSL. Use when user asks to "deploy", "publish", "host", or make their app "live". Triggers include "deploy my app", "make it live", "publish site", "host my app", "deploy website", "put it online".
This skill should be used when the user asks to "create a location", "add a location", "magic system", "political system", "build the world", "add culture", "world history", "technology system", "religion", "economy", or wants to develop any aspect of a story's world and setting.
Writes product-led content pages optimized for both search engines and AI engine citations. Produces markdown files with frontmatter, following page-type frameworks (comparison, guide, use case, learn, trust) with verified sources and no fabricated data.
Make weekly startup growth decisions using growth rate, user behavior, and experiment evidence. Do not use this skill for runway, burn, or profitability trajectory analysis; use `yc-default-alive-calculator` for financial sustainability.
Generate AI images from text prompts — one API key for GPT Image, Gemini, Seedream, and 10+ models. No juggling subscriptions. Images saved to your YouMind knowledge board. Use when user wants to "generate image", "create image", "AI image", "text to image", "生成图片", "AI 生图", "画像生成", "GPT image", "Gemini image", "Seedream", "DALL-E", "Midjourney".
Extract and summarize YouTube video transcripts via YouMind API — no yt-dlp, no proxy needed. Batch extract up to 5 videos at once with parallel processing. Saves videos to your YouMind board with timestamped transcripts in markdown. Automatically summarizes video content after extraction. Works from any IP (cloud, VPS, CI/CD, corporate networks). Use when user wants to "get YouTube transcript", "extract video subtitles", "transcribe YouTube video", "batch transcribe videos", "get video captions", "summarize YouTube video", "YouTube video summary", "summarize this video", "what does this video say", "YouTube 字幕", "YouTube 总结", "视频总结", "YouTube 文字起こし", "YouTube 자막", or "download YouTube transcript".
Build, update, serve, or fork the user's personal zframes market dashboard. Use when the user says "/zframes", "build me a dashboard", "set up my terminal", "make me a market terminal", "add X to my dashboard", "start/open/serve my dashboard", "fork this dashboard <url>", "run this shared zframes link", or wants a personalized live market dashboard (crypto + stocks). If they give a zframes explorer link (a .../dashboard/<id> URL), fork it onto their machine. If a dashboard already exists and the user just wants to start it, serve it — don't rebuild from scratch. Writes a validated dashboard.json and serves it live with the CLI — the agent never writes React.
Use when the user needs a spoken script for short-form video — TikTok, Reels, or YouTube Shorts — with a 3-part hook, second-by-second beats, two A/B variants, shoot notes, and a viral score. Switches between product mode and personal brand mode from the context file. Trigger on 'video script', 'TikTok script', 'Reels script', 'Shorts script', 'what should I say in the video', 'write me a hook for a video'. Also use when the user has a video idea and knows only the topic. Not for — cut and edit instructions for an editor, see `44-video-editor-brief-global`; paid ad copy, see `05-ad-copy-global`; briefing an outside creator to film it, see `06-ugc-egc-brief-global`.
End-to-end implementation playbook for registering WordPress Abilities API capabilities in a WooCommerce extension. Builds on the portable skills in WordPress/agent-skills (`wp-abilities-api`, `wp-abilities-audit`, `wp-abilities-verify`) and adds the Woo-extension scaffolding, conventions, and PR workflow.
Use when the user wants prose rewritten, tightened, audited, simplified, polished, humanized, grammar-checked, or made plainer, clearer, shorter, easier to scan, or easier to act on without changing the intended meaning, audience, tone, or explicit constraints. Trigger on requests such as plain English, simple English, make this clearer, make this more direct, clean this up, edit this, review this writing, grammar check, too wordy, too formal, less fluffy, friendlier, shorter, audit then rewrite, keep the tone, mode=strict, STE, ASD-STE100, or ADHD-friendly. Also trigger for docs, prompts, emails, UI copy, support replies, release notes, status updates, incident notes, procedural text, and other LLM-written prose. Prefer this skill when the main job is improving English prose or preserving tone while increasing clarity, including audit-only requests and exact-text-preservation constraints, but not when the real task is fact-checking, policy setting, or substantive content design.
Curate claude_code/codex session transcripts into a corpus of RAW .jsonl trajectory material for agentic analysis. Scans candidates by workspace/topic, lets an agent screen them and a human mark keep/drop, then copies the kept sessions byte-for-byte with a sha256 manifest. Use when extracting trajectory material, building a dataset of past agent sessions, filtering sessions by workspace, project, or topic, or when the user wants to pick conversations to keep from their agent history.
