Analyze web app codebases against a battle-tested 10-point MVP launch checklist. Based on "Realistic MVP Launch Checklist (from building 30+ apps)".
/launch-check
The 10-Point Checklist:
Philosophy: "Don't overbuild. Just make it stable, usable, and something people can trust."
See plugins/mvp-launch/README.md for full documentation.
AI-native product management for startups. Process signals, not features.
After installing, just ask Claude Code:
"Analyze my product"
"Research competitors"
"Find feature gaps we should build"
"What should we build next?"
/pm analyze # Deep product understanding
/pm landscape # Market overview + competitors
/pm gaps # Batch gap analysis with WINNING scores
/pm file # Create GitHub Issues for top priorities
/pm roadmap # Organize into Now/Next/Later
Prioritize with objective scoring: WINNING = Pain × Timing × Execution
This skill handles WHAT to build (product discovery). For HOW to build, use spec-kit:

Survey design framework grounded in proven research methods (Caroline Jarrett's Surveys That Work, Dillman's Tailored Design, Tourangeau's cognitive model). Captures user intent — what people are actually trying to do, what friction they face, what outcomes they want — without leading questions, satisficing bait, or shallow Likert noise. Includes a 4-part hybrid structure (discovery / diagnostic / intent / segmentation), a question library with behavioral anchors, and three battle-tested templates (event organizers, startup founders, gig-economy workers). Supports text, voice, and AI-interviewer modalities. Bundles the `rethink-survey` MCP server with tools for designing, critiquing, scoring, and clustering survey responses. Use when designing a new survey, critiquing an existing one, or turning survey questions into an app scaffold.
Generate native PPTX files using Anthropic Platform Skills. No ugly python-pptx - uses Anthropic's server-side rendering engine.
Web app MVP launch readiness checker. Analyzes existing codebases against a battle-tested 10-point checklist (Stripe, mobile, onboarding, AI stability, emails, logging, feedback, auth, domain, database). Identifies gaps, confirms understanding with user, and produces prioritized action items. Philosophy: Don't overbuild.
Ultra-compressed communication mode. Cuts 65% of output tokens (measured) while keeping full technical accuracy by speaking like a caveman.
Multi-model consensus engine integrating OpenAI Codex CLI, Gemini CLI, and Claude CLI for collaborative code review and problem-solving.
Comprehensive UI/UX design plugin for mobile (iOS, Android, React Native) and web applications with design systems, accessibility, and modern patterns
Unified capability management center for Skills, Agents, and Commands.
Memory compression system for Claude Code - persist context across sessions
Standalone image generation plugin using Nano Banana MCP server. Generates and edits images, icons, diagrams, patterns, and visual assets via Gemini image models. No Gemini CLI dependency required.
