Buildfastwithai@Gen AI Experiments

Build or transform lightweight realtime voice-chat apps with a talking character avatar from either a user-supplied photograph or a text description. Use when Codex is asked to create a talking avatar, photo avatar, character chatbot, roleplaying voice companion, mouth-sprite animation, or reusable OpenAI Realtime avatar app in Vite/Next.js, including BYOK API-key intake, identity-consistent image generation, audio-driven lip sync, testing, and deployment.

Audit and revamp existing web interfaces into polished, professional, product-specific experiences while preserving behavior and working within the current frontend stack. Use for requests to improve a vibe-coded, generic, template-like, inconsistent, dated, amateur, or visibly AI-generated UI; redesign an existing page, app, dashboard, landing page, or component; establish stronger art direction, hierarchy, typography, spacing, color, responsiveness, accessibility, interaction states, or visual coherence; or perform a premium UI polish pass on HTML, CSS, JavaScript, React, Vue, Svelte, Next.js, and similar frontend codebases.

Build a complete, polished, production-quality browser game inside a single self-contained HTML file using only vanilla HTML, CSS and JavaScript — no frameworks, no libraries, no external assets. Use this skill whenever the user asks for a game, a playable demo, a prototype, an interactive toy, or anything "inspired by" an existing title — platformers, tower defense, RTS, racing, RPGs, physics games, city builders, simulations, card games, survival, idle/incremental, puzzle and arcade games all qualify. Trigger it even when the user never says "HTML" or "single file", and even for requests that sound small ("make me a snake game", "something to kill five minutes"), because the default deliverable is always one finished .html file with menus, art, sound, particles and save support built in. Also use it when the user wants an existing single-file game extended, rebalanced, or polished.

Build or transform ecommerce websites from loose company, product, or brand briefs into unconventional, brand-specific shopping experiences with original ImageGen product imagery. Use when a user asks for a crazy, wild, experimental, unconventional, anti-template, art-directed, or highly memorable online store; wants Codex to invent an ecommerce visual direction from business details; or wants a working storefront that combines creative concepting, generated product photography, responsive implementation, cart interactions, validation, and optional publishing.

Audit a startup, SaaS, app, developer tool, landing page, or product before launch from a live URL, localhost page, repository, screenshots, or supplied copy. Use when Codex needs to determine what a startup appears to do, test whether its public experience is launch-ready, inspect positioning, calls to action, product proof, trust, UX, accessibility, responsive behavior, broken paths, technical surface, or launch operations, produce a Ready to launch / Launch after critical fixes / Not ready yet verdict, prioritize exact improvements, or create a polished standalone HTML launch-readiness report.

Recreate a UI screenshot, mockup, or design image as production-quality React + TypeScript + Tailwind code with near-pixel-perfect visual fidelity. Use this skill whenever the user shares an image of an interface and wants it built, cloned, converted, or "made real" — including phrasings like "build this", "recreate this design", "code this Figma export", "clone this landing page", "turn this mockup into React", "make a component that looks like this", or when they paste a screenshot of a website/dashboard/card/pricing table/navbar with little explanation. Also use it when the user asks for HTML/CSS from an image, or wants an existing component restyled to match a reference image. Trigger even if they never say the words "React" or "Tailwind" — this is the default path for image-to-UI work.

Measure whether Python tests detect behavior changes through diff-scoped mutation testing. Use when Codex needs to audit the strength of a pytest suite, evaluate whether tests cover changed code, investigate surviving mutants, or propose and verify targeted tests for missed behavior.

Find and qualify evidence-backed potential first customers, early adopters, design partners, or beta users for a startup using recent public pain and buying signals. Use when Codex needs to analyze a product URL or idea, define an ideal customer profile, research public discussions and business pages, identify first-user prospects, rank lead fit and timing, prepare source-based outreach drafts, or create a shareable early-customer prospecting report without sending messages automatically.

Turn a startup, SaaS, app, developer tool, website, repository, or product idea into an evidence-backed business plan, monetization strategy, pricing architecture, editable 12-month financial model, and 90-day execution roadmap. Use when Codex needs to analyze how a startup can become a sustainable business; decide free versus paid, monthly, annual, usage-based, one-time, or lifetime pricing; design tiers and upgrade triggers; estimate unit economics and break-even under explicit assumptions; compare scenarios; or produce a native Markdown business plan, formula-driven Excel workbook, and CSV roadmap from a URL or description.
