Use when the user writes /goal MVP, /goal mvp, Goal MVP, GoalMvp, $GoalMvp, $goal-mvp, or asks to turn a goal, idea, app concept, startup concept, game concept, automation, plugin, or Codex skill into a small buildable MVP. This skill runs a five-step workflow: clarify with mandatory questions, scope, plan, build, verify and launch.

Use when the user writes /goal MVP, /goal mvp, Goal MVP, GoalMvp, $GoalMvp, $goal-mvp, or asks to turn a goal, idea, app concept, startup concept, game concept, automation, plugin, or Codex skill into a small buildable MVP. This skill runs a five-step workflow: clarify with mandatory questions, scope, plan, build, verify and launch.

Brutally evaluate and refine startup ideas with practical early-stage startup frameworks. Use when Codex is asked to pressure-test a startup idea, validate whether the problem is real, map competitors and current customer behavior, find the first 10 customers, define an MVP, create a 2-week launch plan, assess founder-market fit, or give a direct strong/weak/pivot verdict.

Analyze a software codebase for algorithmic complexity and performance hotspots, then propose or implement safe optimizations without breaking behavior. Use when Codex is asked to scan many files, find inefficient loops, nested iteration, repeated scans, costly rendering/recomputation, N+1 queries, avoidable O(n^2) or O(n) operations, or reduce complexity such as O(n^2) to O(n log n) / O(n), while preserving tests, APIs, outputs, and maintainability.

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.

Use this skill to find and qualify local business prospects near a location, especially shops, gyms, restaurants, clinics, salons, and local services that may need a website. It uses the integrated browser for assisted research, checks whether each business has a real website or only social profiles, and returns a concise lead sheet in chat or CSV-style rows.

Build and iterate mobile apps that run on a real phone through Expo/React Native live preview. Use when Codex is asked to create a phone app, prototype an iPhone or Android app, run an app on a physical phone, show a QR code for Expo Go, set up a mobile dev workflow, or turn a prompt into a live mobile app without starting from Xcode/TestFlight/App Store distribution.

Find likely software bugs in a codebase, rank concrete bug candidates, and prove or reject them with focused regression tests before proposing a fix. Also turn bug reports, stack traces, screenshots, failing behavior, support tickets, and regressions into minimal reproducible cases with red-to-green evidence. Use when Codex needs to hunt for unknown bugs, audit code for correctness defects, test suspicious edge cases, reproduce a reported failure, isolate root cause, or verify that an approved fix works without regressions. Always require explicit approval before creating reproduction files and separate approval before changing production code.

Evaluate website, web app, landing page, or frontend implementation quality with a structured design audit and scoring grid. Use when Codex is asked to review UI design, visual hierarchy, UX, responsiveness, accessibility, performance perception, copy clarity, frontend polish, or to produce a design/frontend evaluation rubric for a URL, localhost app, screenshot, repository, or live page. Also use for re-audits that compare before vs after changes, track score deltas, and verify whether prior design/frontend issues were fixed.

Audit and refine landing pages to avoid generic AI-generated visual quality problems using Meng To's frontend design checklist. Use when Codex is asked to review, polish, improve, redesign, or prepare a landing page before launch, especially for typography, letter spacing, font choice, image authenticity, AI-generated visuals, prompt quality, micro-interactions, and final human design details.

Create short clips from local video files using ffmpeg, with optional local Whisper subtitles. Use when Codex is asked to turn a long local video into a short, trim boring pauses, remove dead air, cut silence, create a 30-60 second clip, export a vertical 9:16 MP4, generate captions/subtitles, burn subtitles into a video, or generate a simple edit report. Base editing is ffmpeg-based; subtitles use local whisper.cpp and do not require an API key.

Simulate how five plausible customer personas experience a startup, SaaS, app, or landing page, explain why each would convert, hesitate, or leave, and produce a polished standalone HTML report. Use when Codex needs to test a live URL, localhost app, screenshot, prototype, or landing-page copy for positioning, first-impression clarity, relevance, trust, objections, conversion friction, CTA effectiveness, mobile experience, prioritized improvements, or a shareable launch-readiness report.

Find wasted disk space on macOS and propose cleanup candidates. Use when the user asks Codex to scan a Mac/MacBook for useless files, wasted storage, large caches, logs, downloads, build artifacts, Xcode simulator data, Docker/container leftovers, package-manager caches, node_modules, duplicate archives, old installers, or to free disk space. Always run read-only analysis first and ask explicit permission before deleting or moving anything.
