UiPath automation discovery — mines Slack/email/wikis/CRM/HRIS/ERP for repetitive work, SPOFs, and replicable models; produces a 4-tier prioritized opportunity report with UiPath implementation paths, then sizes build effort (complexity band → pack-hours → contingency). Use to discover automation opportunities, find what to automate, estimate/size a delivery, or run an internal automation audit across an organization. For building a specific automation→uipath-rpa, authoring a Flow→uipath-maestro-flow, working with agents→uipath-agents.
UiPath Coded Functions — deterministic Python or TypeScript/JavaScript units built with the `uip function` CLI (`new -l py|ts|js`, `init`, `serve`, `run`, `pack`, `publish`); the `functions` map in `uipath.json` marks the project. Python: Pydantic Input/Output models, lazy `UiPath()` SDK singleton. JS/TS: `defineFunction` + `defineSchema<T>()` contracts, HTTP endpoints for Coded App backends or run-as-job, `FunctionError`. Rule-based logic, data transforms, ERP/Integration Service calls — invoked as Maestro Service Tasks, from agents, via Orchestrator `POST /Jobs/StartJobs`, or HTTP triggers; no LLM reasoning or agent loop. For LLM/agentic projects (LangGraph, LlamaIndex, OpenAI Agents, `agent.json`)→uipath-agents. For the Coded App frontend itself (React app code, PKCE setup, app deploy)→uipath-coded-apps.
UiPath Insights historical monitoring via `uip insights`: job metrics, failure analysis, and process performance; queue totals, SLA risk, timelines, and failure drill-down; machine availability, fault ranking, and runtime minutes; filter discovery of scope; alert definition, history, delivery, and entitlement reads; Insights user, role, and group reads; Maestro process dashboard reads and writes; export destination checks; Looker dashboard lists and embed URLs. For live Orchestrator records or job start/stop/logs→uipath-platform, root-cause analysis→uipath-troubleshoot, workflow authoring→uipath-rpa, org identity→uipath-admin.
Install, configure, and use the Unity Command Line Interface (CLI) for automated production workflows, project management, and cloud integration. Use when setting up CLI-based build automation, CI/CD pipelines, Editor/module management, authentication, or localhost API calls via the experimental Unity Pipeline package. Designed for verifiable, machine-readable game production workflows where the build machine must be describable and tests must return evidence. Triggers on: Unity CLI, unity command line, unity automation, unity ci/cd, unity build script, unity pipeline, unity production workflows.
Drive a live Unity Editor or Player with unity-cli. Use when a task must inspect or change Unity scenes, GameObjects, components, transforms, prefabs, materials, ScriptableObjects, project assets, play mode, screenshots, profiler recording, Unity Test Framework runs, or execute C# inside Unity; also use for Unity console maintenance and unity-cli setup, status, refresh, snippets, or custom commands. Do not use for source-only Unity coding that does not require interaction with the live Editor or Player.
Unity 6 graphics and rendering guide. Use when working with render pipelines (URP, HDRP, Built-in), shaders, Shader Graph, materials, textures, cameras, post-processing, or rendering optimization. Covers Render Graph, batching, draw call optimization, and GPU instancing. Based on Unity 6.3 LTS documentation.
Upload PDF slides to CDN and configure chapter README with slides metadata. This skill should be used when adding teaching presentation slides to a chapter. Handles: PDF upload, part/chapter resolution, README frontmatter update, Teaching Aid heading.
Design and audit user preferences, personalization controls, notification settings, privacy toggles, accessibility options, language/region settings, theme, default behavior, reset/export behavior, cross-device sync, and settings discoverability. Use when users need durable control over product behavior without confusing admin policy, billing, or security settings.
Use when a Backstage frontend plugin needs information about the currently logged-in user — their entity ref, profile info, ownership refs, or auth token. Triggers on phrases like "current user", "logged-in user", "my groups", or imports of identityApiRef.
Expert in using v0.dev for AI-powered UI generation. Covers prompting strategies, component iteration, shadcn/ui integration, export workflows, and customization. Knows how to get the best results from v0 and integrate generated components into production codebases. Use when "v0, v0.dev, generate ui, shadcn component, ai component, generate component, v0, v0-dev, ui-generation, shadcn, component-generation, ai-ui, vercel" mentioned.
This skill should be used when the user asks about overvalued, undervalued, fairly valued, P/E ratio, forward P/E, PEG ratio, EV/EBITDA, EV/EBIT, price to earnings, price to sales, price to book, P/FCF, price to free cash flow, DCF, discounted cash flow, intrinsic value, enterprise value, earnings yield, margin of safety, or valuation for a specific company.
Takes a startup product URL or description, detects the industry and funding stage, identifies 5 comparable funded companies, searches who invested in those companies (Track A), finds VCs who publish investment theses about this space (Track B), and returns a ranked sourced list of relevant investors with deep-dives and outreach hooks. Use when asked to find investors for a startup, identify which VCs fund products like mine, research who backs companies in my space, build a VC target list, or find investor-market fit.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Review applications and verify task submissions on OpenAnt. Use when the agent (as task creator) needs to review applicants, accept or reject applications, approve or reject submitted work, download submission files, or give feedback on deliverables. Covers "review applications", "approve submission", "reject work", "check applicants", "verify task", "download submission files".
Enforce Vertical Slice Architecture (VSA) when building applications in any language (Go, .NET/C#, Java, Kotlin, TypeScript, Python, etc.) and any type (web API, mobile backend, CLI, event-driven). Organize code by feature/use-case instead of technical layers. Each feature is a self-contained vertical slice with a single entry point that receives the router/framework handle and its dependencies. Use when the user says "vertical slice architecture", "VSA", "organize by feature", "feature-based architecture", "slice architecture", or when building a new app or feature and the project already follows VSA conventions. Also use when reviewing or refactoring code to align with VSA principles.
Use when the user explicitly invokes this skill to create, refresh, or localize a repository's agent instruction files — AGENTS.md, CLAUDE.md, and personal local rules in AGENTS.override.md and CLAUDE.local.md — or to check that instruction-file policy against current best practice. Do not use for ordinary documentation edits, for implicit mentions of AGENTS.md, or for any request that does not explicitly invoke it.
Edit and compose video on a timeline. Use when the user wants to add background music, a voiceover or another audio track, put text, a logo or an image overlay on a video, join several videos or images into one with fades or other transitions, add animated or word-by-word karaoke captions, change the resolution or aspect ratio of a composition, or generate music, voiceover, images or video with AI for a composition. Static subtitles with a chosen font and position belong to video-subtitles.
Use when building, polishing, or reviewing the interface of a Video.js 10 player: custom controls and overlays, control bars, menus and popovers, sliders, time displays, icons and icon states, motion, color, and control labels, in skin source or in custom components that read player state. Applies interface-craft skills such as Jakub Krehel's better-* skills, Emil Kowalski's design and animation skills, and an accessibility audit, within the constraints of UI that sits over moving video.
Helps merchants spot viral hits on social (e.g. TikTok fidget toys, visual jewelry) and gives fast selection and testing advice. Trigger when users ask "what’s trending on TikTok lately," "can this product go viral," "how to quickly follow a social trend," or mention strong visual impact, impulse buy, or social sharing—and use this skill.
Generate beautiful, self-contained HTML pages that visually explain systems, code changes, plans, and data. Use when the user asks for a diagram, architecture overview, diff review, plan review, project recap, comparison table, or any visual explanation of technical concepts. Also use proactively when you are about to render a complex ASCII table (4+ rows or 3+ columns) — present it as a styled HTML page instead.
Surgical aesthetic upgrade pipeline for existing React codebases. Takes ugly, functional code (Bootstrap defaults, generic Tailwind, amateur CSS) and transforms it to Awwwards-tier quality WITHOUT touching or breaking the underlying JavaScript logic - states, effects, API calls, event handlers, routing, and data flow are sacred and untouchable. Audits the existing code across 7 layers (tokens, typography, spacing, color, components, atmosphere, motion), classifies every element as Sacred (JS logic - do not touch) or Slop (visual cruft - upgrade), then executes precise CSS-only surgery layer by layer. The skill that turns a developer's "make this look better" into a controlled, non-destructive visual transformation.
Comprehensive visual regression testing using Playwright and jest-image-snapshot. Implements screenshot comparison, baseline management, CI/CD integration, and visual diff reporting following Ant Design best practices. Use for preventing visual bugs, ensuring UI consistency, and automating visual QA. (project)
Build, review, debug, configure, migrate, teach, or plan Vitest testing with current docs and a full usage guide. Use for vitest 5, vitest.config, defineConfig from vitest/config, describe/it/test/expect, vi mocks, vi.when, snapshots, coverage (@vitest/coverage-v8), browser mode (@vitest/browser-playwright), projects, pools/maxWorkers, reporters, UI, bench fixture, typecheck, vitest doctor, fsModuleCache, and Jest / Vitest 3→4 / 4→5 migration.
Text-to-speech voice toolkit. DEFAULT ACTION: When called with text (e.g. /voicebox hello), IMMEDIATELY run: uv run $SKILL_DIR/scripts/voicebox.py generate \"Calm Narrator\" \"<text>\" --play. Do NOT ask questions, do NOT greet the user — just generate and play the speech. Also supports: voice cloning, multi-speaker conversations, recording, and transcription.
Send WhatsApp messages to other people or search/sync WhatsApp history via the wacli CLI (not for normal user chats). Use when the user asks to send a WhatsApp message, text someone on WhatsApp, search WhatsApp chat history, sync WhatsApp conversations, backfill message history, or forward a file via WhatsApp to a third party.
Managing Walrus blob lifecycles: epochs, lifetimes, extending blobs, deleting blobs, burning blob objects, sharing blobs, setting blob attributes, and handling large uploads. Use when the user needs to extend a blob's lifetime, delete or burn blobs, create shared blobs, set/get/remove blob attributes, plan large data uploads (>1 GiB), estimate storage costs, manage concurrent upload memory, or understand epoch-based expiration. For basic store/read, see `walrus-cli`. For quilts, see `walrus-quilts`.
Common Walrus error messages, their causes, and fixes. Use when the user encounters an error while using Walrus CLI, TypeScript SDK, HTTP API, or Move integration. Covers VMVerificationOrDeserializationError, ChainNotSupportedError, tip exceeded, RetryableWalrusClientError, file.bytes is not a function, 413 Payload Too Large, BlobNotCertifiedError, spawn walrus ENOENT, Cannot find gas coin, EWrongVersion, and other errors the documentation and the SDK source describe.
Search for financial reports using Exa advanced search. Near-full filter support for finding SEC filings, earnings reports, and financial documents. Use when searching for 10-K filings, quarterly earnings, or annual reports.
This skill helps users automatically extract complete Markdown content from any website via the BrowserAct Web Search Scraper API. The Agent should proactively apply this skill when users express needs like extract complete markdown from a specific website, scrape the content of an article link, get the text from a target url, convert a webpage to markdown format, fetch the main content of a blog post, extract data from a given web page, parse the html of a website into markdown, download the readable text from a news article, obtain the content of a tutorial page, extract all the markdown text from any http or https url, scrape documentation from a web link, or grab the text of a single webpage.
