Evaluation criteria: - Market: Is this crowded? Who else is doing this? What's different? - Demand: Do people actually want this or just say they do? - Feasibility: Can a solo builder ship this in 2-4 weeks? - Monetization: How would this make money? Are people paying for similar things? - Interest factor: Is this boring or actually compelling? Be brutally honest. I'd rather hear "this has been done 100 times" now than after building for a month. Output format: - Quick verdict: Build it, Maybe, or Skip it - Why (2-3 sentences) - Similar existing products - What would make this idea stronger Use this skill before starting any project to save me from building stuff nobody wants. **2. Launch Planner** ``` Create a skill called "Launch Planner" that helps me take app ideas and turn them into shippable MVPs. Include: - My product philosophy: ship fast, validate with real users, no feature creep - My preferred tech stack: Next.js, Supabase, Vercel deployment - MVP scoping rules: only features that serve the core user loop, nothing that takes more than 1 week to build - Questions to ask before building anything: Who is this for? What's the one problem it solves? How will I know if it works? - Common mistakes to avoid: building features nobody asked for, over-engineering, adding auth before validating the idea Use this skill to: - Generate PRDs from ideas - Create starter prompts for Claude Code - Advise me on product decisions throughout the build - Keep me focused on shipping ``` ## Claude Code Skills **3. Design Guide** ``` Create a skill called "Design Guide" that ensures every UI I build looks modern and professional. Design principles: - Clean and minimal - lots of white space, not cluttered - Neutral color palette - use grays and off-whites as base, ONE accent color used sparingly - NO generic purple/blue gradients - Consistent spacing using 8px grid system (8, 16, 24, 32, 48, 64px) - Typography: clear hierarchy, readable sizes (16px minimum for body text), max 2 fonts - Subtle shadows, not heavy or overdone - Rounded corners but not everything needs to be rounded - Clear interactive states (hover, active, disabled) - Mobile-first thinking Good examples: - Buttons: subtle shadow, proper padding, clear hover state, no gradients - Cards: clean borders or subtle shadows, not both - Forms: proper labels, clear error states, good spacing between fields Bad examples: - Rainbow gradients everywhere - Tiny unreadable text - Inconsistent spacing - Every element is a different color Reference this skill whenever building any UI component. ``` **4. Marketing Writer** ``` Create a skill called "Marketing Writer" that writes marketing content for my product and features. Read the codebase to understand what the app does, what features exist, and the core value proposition. My brand voice: - Casual and direct, like talking to a friend - No corporate buzzwords or cringe marketing speak - Focus on real benefits, not hype - Use simple language, avoid jargon Include templates for: - Landing page feature sections (problem → solution → benefit format) - Tweet threads (hook, build credibility, show value, CTA) - Launch emails (personal, specific value prop, easy CTA) Use this skill whenever I ship a feature or need to write marketing content. Automatically understand the context from the codebase so I don't have to explain what my app does. ``` **5. Roadmap Builder** ``` Create a skill called "Roadmap Builder" that helps me decide what to build next for my product. My prioritization framework: - Impact vs Effort matrix - prioritize high impact, low effort first - Categories in order of importance: Retention - Core features - Monetization - Growth - Stage-based rules: * Pre-launch: ONLY core loop features, nothing else * Post-launch: ONLY features users explicitly request * Growth phase: Features that reduce churn or increase sharing Questions to ask about every feature: - Does this serve the core use case? - Will users actually use this or just say they want it? - Can we fake it first to validate demand? Red flags: - Feature creep - adding things because they're "cool" - Premature optimization - Building for imaginary users, not real ones Use this skill to: - Advise what to build next - Challenge feature ideas - Keep roadmap focused on what matters Timestamps: 0:00 Intro 0:33 What are Claude Skills 3:19 Idea Validator Skill 8:30 Launch Planner skill 12:11 Designer Skill 15:59 Marketing Skill 21:14 Product Manager Skill
