Product-thinking toolkit for builders. Audits your project through Kotler's marketing lenses — challenging you to think beyond features and see your product from the customer's perspective.
Full product audit through 4 marketing lenses — challenges you to think beyond features. Use when asked to audit, review, or analyze a product from a marketing perspective.
Provides marketing-aware nudges when the user is writing customer-facing content like READMEs, landing pages, pricing pages, or onboarding flows. Detects feature-centric language and suggests customer-centric alternatives.
Quick myopia check — are you building the drill or solving the hole? Fast 3-minute gut-check on your product positioning.
A Claude Code plugin that audits your product through Kotler's marketing lenses. Stop building features nobody asked for — start solving problems people will pay for.
Market Lens challenges you to think about your product from the customer's perspective. It scans your codebase, asks pointed questions, and runs you through 4 marketing lenses — acting as a provocative sparring partner, not a polite reviewer.
| Lens | Question | What It Catches |
|---|---|---|
| Myopia Check | Are you selling the drill or the hole? | Feature-obsession, technical jargon in customer-facing copy |
| Value Perception | What does the customer get vs give? | Onboarding friction, hidden costs, unclear value props |
| Satisfaction Risk | Where will expectations break? | Over-promises, poor error states, promise-delivery gaps |
| Retention Signal | Why would they come back tomorrow? | Missing engagement hooks, one-time-use patterns |

Myopia check only — fast gut-check on whether you're building the right thing.
The product-thinking skill activates automatically when you're editing customer-facing content (README, landing pages, pricing). It provides brief marketing-aware nudges without interrupting your flow.
After running /market-lens:audit, you get a PRODUCT-AUDIT.md like:
## Lens 1: Myopia Check 🔴
Finding: Your README opens with "A Next.js application with real-time
WebSocket support and PostgreSQL backend." Your customer doesn't care
about your stack. They care about what problem you solve.
Recommendation: Rewrite your README opening to: "For [target user]
who [has this problem], [Product Name] [solves it by]..."
Frameworks derived from Philip Kotler's Principles of Marketing — adapted for builders who work in code, not boardrooms.
