TAM/SAM/SOM calculator with deep market research. Produces comprehensive market-sizing.md with top-down and bottom-up estimates, methodology, data sources, assumptions, sensitivity ranges, growth projections, competitive landscape, and Mermaid visualizations. Use when user needs market size estimates, addressable market analysis, go-to-market sizing, investor-ready market analysis, or business plan market validation.
Pixel-faithful clone of any web UI into the user's existing stack, using whatever sources are available — a screenshot alone, a live URL, raw HTML/CSS, or any combination. Use this skill whenever the user wants to recreate, match, replicate, or "clone" a design from a screenshot, image, URL, Figma export, or HTML dump. Trigger on phrases like "clone this", "match this design", "build this from screenshot", "recreate this page", "make it look like this", "rebuild this UI", "copy this layout", or any time the user provides a visual reference and asks for a faithful implementation. Do not undertrigger — even if the user just drops a screenshot without explicit phrasing, this skill applies.
Context-aware translation that preserves tone, style, and natural word order. Use when translating UI strings, documentation, marketing copy, or any multilingual content. Infers register, domain, and style from the source text and surrounding codebase context.
Build a compilable type-level skeleton from a high-level architecture spec before writing any implementation logic. Use when you have an architectural assessment, design doc, or restructuring plan and need to prove the new architecture is sound before migrating code. Also use when asked to "scaffold the new architecture", "create type stubs", "build the shell", "flesh out this spec", "skeleton the modules", or any request to turn architectural intent into verified structure. This skill follows the "Human Builds the Shell" paradigm: types are hard constraints that the compiler enforces, so if the skeleton compiles, the architecture is structurally sound. Especially valuable for large refactors where you don't trust agents to maintain coherence.
[Hyper] Create or update a ManyFast-style AI planning package from a rough product idea: PRD, visual planning diagram, feature spec, user flow, low-fidelity wireframe, HTML preview viewer, source log, and optional flow tracking under `.hypercore/prd/[slug]/`. Use when the user wants product planning output before implementation, especially PRD plus diagram/specs/flows/wireframes.
[Hyper] Use when working on Next.js projects or introducing App Router into a codebase. Enforces official Next.js architecture rules for app structure, Server and Client Component boundaries, server-first data fetching, and a default decision order of Server Components for reads, Server Actions for internal writes, Route Handlers for HTTP-native endpoints, and Proxy only as a last resort.
[Hyper] Create new Codex skills or refactor existing skill folders when the user asks for a reusable skill, better trigger wording, cleaner resource placement, or stronger validation across `SKILL.md`, `rules/`, `references/`, `scripts/`, and `assets/`.
Draft social media posts to share valuable readings, articles, or resources. Use when user wants to share a link, article, or reading on social media (X/Twitter, Substack, 知识星球), or mentions "分享这篇文章", "share this article", "write a post about this", "推荐一下这个", or provides a URL and asks to write sharing content.
Generate comprehensive email marketing strategy with 90-day implementation roadmap. Analyzes business type (local-business, saas, ecommerce, creator, agency) to deliver industry-specific segmentation plans, automation sequences, content calendars, KPI targets, platform recommendations, and week-by-week rollout schedule. Use when building email program from scratch or restructuring existing strategy.
OpenLess open-source voice input for macOS & Windows — press a hotkey, speak, get AI-polished text inserted at your cursor in any app.
Add security protection to a server-side route or endpoint — rate limiting, bot detection, email validation, and abuse prevention. Works across frameworks including Next.js, Express, Fastify, SvelteKit, Remix, Bun, Deno, NestJS, and Python (Django/Flask). Use this skill when the user wants to protect an API route, form handler, auth endpoint, or webhook from abuse, even if they describe it as "add rate limiting," "block bots," "prevent brute force," or "secure my endpoint" without mentioning Arcjet specifically. Uses the Arcjet CLI (`npx @arcjet/cli` or `brew install arcjet`) for authentication, site/key setup, remote rule management, and traffic verification.
