Debug and emulate specific code fragments or functions using the Unicorn engine. Activate when the user wants to emulate a function with Unicorn, trace binary execution without running the full program, decrypt or decode data by emulating the algorithm, or bypass environment dependencies (JNI, syscalls, libc) during emulation.
Find or sharpen the project idea and write the scope doc. The first and most important planning conversation — a focused flipped-interaction interview that pulls the idea out of the learner's head, then cuts it down to a coherent proof of concept. Run after 1-start.
Finish the Build With AI Basics hackathon—verify the proof of concept, prepare the required short demo video and public GitHub repository, and write your own Devpost submission. Run after 5-build, its final review, and the learning wrap-up/app map are complete.
Build a sourced, corroborated profile of a named individual from public records, social platforms, professional networks, court and property filings, licensing boards, patents, papers and obituaries — anchoring the name to a second selector first so you never fuse two people into one dossier. Use when asked to find, identify, background-check or profile a person, verify someone's claimed employment or credentials, or locate a missing or hard-to-reach individual. Applies to counterparty and investor due diligence, fraud and asset investigation, journalism, skip tracing, missing persons, pre-employment integrity checks on fiduciary roles, and self-exposure audits.

Begin Build With AI: Basics, the Devpost learning hackathon. Checks you're in a fresh project folder, introduces flipped interaction, learns about your idea and background, and writes the learner profile that every later skill reads. Run this first.
Use this skill when the user requests a newsletter, email digest, weekly roundup, industry briefing, or curated content summary. Supports topic-based research, content curation from multiple sources, and professional formatting for email or web distribution. Trigger on requests like “create a newsletter about X,” “write a weekly digest,” “generate a tech roundup,” or “curate news about Y.”
Runs the payroll-confidence chain end to end—forecasts cash across the payroll window with cash-flow-snapshot, ranks and drafts overdue-invoice reminders with invoice-chase to close any gap, then assembles timesheets, flags every anomaly, and stages the run with payroll-prep. On Gusto the run is staged for the owner to submit; on QuickBooks Payroll, or with no payroll system, the last step is a validated run sheet the owner keys in. This chain never presses the payroll button. Builds on the ledger (MYOB, NetSuite, QuickBooks, Xero, or Zoho Books), with Gmail or M365, PayPal, Square, Stripe, and either Gusto or QuickBooks Payroll adding detail, and falls back to CSV and timesheet uploads. Use it whenever payroll is the worry, including “can I make payroll,” “payroll is due Friday,” “plan payroll,” “will I have enough to pay the crew,” or “I need to run payroll but money is tight.” Accepts optional horizon and payroll-date arguments.
When the user wants to design or optimize the funnel that takes web visitors into installing and onboarding the app — including smart app banners, web-to-app deep links, deferred deep links, web onboarding (Stripe-paid web flow before app install), QR codes, "open in app" CTAs, and the trade-off between paying on web vs in-app. Use when the user mentions "web to app", "smart app banner", "Stripe before app", "web paywall before install", "Branch web SDK", "web funnel for app", "AppsFlyer OneLink web", "Universal Links", "App Links", "QR code to app", "open in app", "deferred deep link from web", or "should I sell on web first then push to app". For pure in-app onboarding, see onboarding-optimization. For deep link infra, see attribution-setup.
Search and ask questions about coding agent session history across Claude Code, Codex, and Cursor. Use when asking what was worked on, what was tried before, how a problem was investigated across sessions, what happened recently, or any question about past agent sessions. Also use when the user references prior sessions, previous attempts, or past investigations — even without saying 'sessions' explicitly.
Plan, draft, audit, and publish LinkedIn posts and comments. Use when the user wants to write a viral LinkedIn post, draft a comment or reply on any LinkedIn post URL, audit a draft against 2026 algorithm heuristics, remove AI tells, extract hook formulas from viral posts, or plan a week of content. Powered by the Publora API for publishing. User provides post/comment URLs, skill drafts content, user approves, then publishes
Run a validated Admin GraphQL operation against a specific store using Shopify CLI. Use this when the user wants an executable store workflow, not just the query or mutation text. If the answer should include `shopify store auth` and `shopify store execute`, choose this API. Choose this for 'my store', 'this store', a store domain, product reads on a merchant store, low-inventory lookups, product updates, and warehouse/location inventory changes. Examples: 'Show me the first 10 products on my store', 'Find products with low inventory on my store', 'Set inventory at the Toronto warehouse so SKU ABC-123 is 12'.
Separate a person, product, or hand from the background in a video on the user's own computer with SAM 2. Scans the machine first to choose the right model size, then outputs the same video with the separated subject highlighted in green, plus frame-by-frame masks. Use when someone wants to separate, isolate, cut out, or rotoscope something in a video.
Instrument an existing codebase with LaunchDarkly config tracking. Walks the four-tier ladder (managed runner → provider package → custom extractor + trackMetricsOf → raw manual) and picks the lowest-ceremony option that still captures duration, tokens, and success/error.
Check if the compound-engineering plugin is up to date and recommend the update command if not. Use when the user says "update compound engineering", "check compound engineering version", "ce update", "is compound engineering up to date", "update ce plugin", or reports issues that might stem from a stale compound-engineering plugin version. This skill only works in Claude Code — it relies on the plugin harness cache layout.
Define what content a product needs, how it is structured, and who owns it. Use when content itself is the problem. For the words in the interface use `ux-writing` (designer-toolkit); for structural hierarchy use `information-architecture`
Discover and evaluate scientific datasets, models, methodology posts, and Spaces through the Hugging Science catalog. Use when selecting scientific ML resources in biology, chemistry, genomics, materials, climate, physics, astronomy, medicine, mathematics, protein design, single-cell analysis, or PDE modeling, and when checking their actual datasets, Transformers, native-runtime, Inference Providers, or Gradio interfaces
Background removal: transparent PNGs, cutouts, product photos, portraits, pets, group photos. Uses dedicated Bria RMBG 2.0 model — no prompt needed, fast (~3s), cheap ($0.01). Use when removing backgrounds, creating transparent PNGs, making cutouts, extracting foreground subjects, or preparing images for compositing.
Help users prioritize product roadmaps and backlogs. Use when someone is deciding what to build next, sequencing features, allocating resources across projects, handling stakeholder requests, or struggling with too many competing priorities.
Investigate a phone number — E.164 normalisation with libphonenumber, phoneinfoga scanning, carrier and line-type identification, VoIP and burner detection, messaging-app registration checks, and reverse-lookup and caller-ID sources. Use for phone OSINT and reverse phone lookup, "who owns this number", identifying a burner or VoIP number, or checking whether a number is registered on WhatsApp, Telegram or Signal. Applies to vishing and business email compromise investigation, verifying a counterparty before sending payment, recruitment and marketplace scam checks, and fraud triage.

Closes the books and turns them into a decision as a three-link chain — month-end-prep reconciles the ledger against every connected payment processor and writes the P&L narrative, cash-flow-snapshot then refreshes the 30/60/90-day forecast off the newly closed numbers rather than raw ones, and report-builder publishes and distributes the close packet. Requires a ledger (MYOB, NetSuite, QuickBooks, Xero, or Zoho Books) and uses Gusto, PayPal, Ramp, Shopify, Square, and Stripe when connected, falling back to statement or CSV uploads. Trigger on “close the month,” “month-end,” “close the books,” “reconcile,” “send the close packet to my accountant,” or when the owner asks why revenue or margin moved last month. An owner who wants only the reconciliation and its flags, with no forecast refresh and no packet distribution, routes to month-end-prep directly.
Summarize Douyin (TikTok China) videos by extracting audio, transcribing with whisper.cpp, and generating structured summaries. Use when a user shares a Douyin link and wants a text summary of the video content. Supports optional sync to Feishu (Lark) docs. Triggers on Douyin URLs (v.douyin.com, douyin.com/video/).
Documentation conventions for NeMo-RL. Covers docs/index.md updates and docstring format. Do NOT use for: bug fixes, test fixes, dependency bumps, refactoring, CI/CD changes, performance tuning, or any task that does not involve writing or updating documentation.
Check and resize images for social media platforms. Run scripts/check.js to validate any image against specs for Instagram, Facebook, X (Twitter), LinkedIn, TikTok, YouTube, Pinterest, Snapchat, and Threads — get a ranked match list with exact resize commands. Run scripts/resize.js to export a correctly-sized copy. Use when a user asks to validate image dimensions, resize an image for a platform, check if an image fits a spec, or prep assets for social media posting or ads.
Use this skill when the user asks to “make a whiteboard animation,” “draw-on explainer,” “VideoScribe style,” “hand-drawn explainer video,” “animate a sketch being drawn,” “do a doodle/scribe video,” “show a hand drawing the illustration,” or “animate handwriting appearing on a whiteboard.” Covers SVG stroke draw-on, a marker hand that follows the path tip, staggered reveal, erase/wipe transitions, and narrated export.
Packaged UI asset kit — polished, visually harmonized MSW UI from official MSWPackages assets. Use when the user wants UI that looks good / polished / pretty / consistent / game-quality, asks for a themed screen or themed part (frame, slot, gauge, arrow, icon), or needs an interaction widget native components lack. (1) 7 theme RUID palettes mined from published-world UI resource packs: parts with RUID, native size, 9-slice type and button states, usable as UIBuilder image_ruid with no install, plus entity-tree digests of 130+ sample and official package screens (inventory, shop, ranking, HUD, dialog). (2) Prebuilt widgets: checkbox, radio button, switch, toggle group, dropdown, pagination, progress bar, scroll picker, time picker, number pad, loading spinner.
Understand images and videos with Qwen vision models. Trigger when the user wants to analyze, describe, or extract information from images or videos, perform OCR text extraction, read charts or tables, do visual reasoning or multi-image comparison, understand screenshots or videos, or explicitly invokes this skill by name (e.g. use qwencloud-vision). Do not trigger when the user wants to generate or create images (use qwencloud-image-generation), generate videos (use qwencloud-video-generation), handle text-only tasks without visual input, or use non-Qwen vision tasks
Material Design 3 and Android platform guidelines. Use when building Android apps with Jetpack Compose or XML layouts, implementing Material You, navigation, or accessibility. Triggers on tasks involving Android UI, Compose components, dynamic color, or Material Design compliance
Foundation skill that captures and stores core brand context — identity, audience, positioning, values, and voice. Use when the user says "set brand context", "save my brand info", "store brand details", "brand profile", "create brand context file", "update brand context", or when starting any brand project for the first time. Every other brand skill reads this file first. Always run this before beginning any brand work if the context file doesn't exist yet.
Migrate Chakra UI projects from v2 to v3, covering package changes, codemods, provider setup, color mode, prop renaming, compound components, theming, recipes, and Next.js updates. Use this skill whenever a user is upgrading Chakra UI versions, encountering breaking changes after an upgrade, converting old v2 patterns (ColorModeScript, useColorModeValue, styleConfig, extendTheme, isDisabled, colorScheme, @chakra-ui/icons, framer-motion dependency), fixing compound component patterns, or asking about differences between Chakra UI v2 and v3 — even if they don't say “migrate” or “upgrade” explicitly.
Chinese financial data access using AkShare library. Fetch real-time and historical data for A-shares, Hong Kong stocks, US stocks, futures, funds, and macroeconomic indicators. Use when user requests Chinese market data, stock prices, market analysis, or financial information from Chinese exchanges. Supports stock quotes, historical data, futures market data, fund information, macroeconomic indicators, and real-time market updates.
Migrate an application with hardcoded LLM prompts to a full LaunchDarkly AgentControl implementation in five stages: audit the code, wrap the call, move the tools, add tracking, attach evaluators. Use when the user wants to externalize model/prompt configuration, move from direct provider calls (OpenAI, Anthropic, Bedrock, Gemini, Strands) to a managed config, or stage a full hardcoded-to-LaunchDarkly migration.
File notes into the right folder in the user's Obsidian vault and audit/reorganize its structure, via the `obsidian` CLI and the `00_Index/Folder_Map.md` map note. Use when a note needs filing, when the user asks where a note belongs, or wants to tidy, deduplicate, audit, or restructure folders. Requires the Obsidian app to be running.
