By Wenjix
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.
Based on adoption, maintenance, documentation, and repository signals. Not a security audit or endorsement.
Jarrett-style critique of an existing survey — finds leading questions, satisficing bait, missing structure, and proposes concrete rewrites
Interactive design session for a new survey — research goal, audience, hypotheses, questions, modality, output schema
Turn a finalized survey design into a working app scaffold (TanStack Start / Next.js / static, with Supabase or local storage)

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:
