Can Product Lens analyze an existing codebase?

Yes, its Founder Review mode scans your README, package files, and recent commits to score product-market fit signals and identify unnecessary features.

What is the main purpose of the Product Lens skill?

Product Lens validates the 'why' behind a feature before development starts, ensuring that engineering efforts are focused on the right problems.

What kind of output does Product Lens provide?

It generates actionable documents like PRODUCT-BRIEF.md, risk assessments, and go/no-go recommendations instead of long, theoretical essays.

Does this skill replace technical documentation?

No, it focuses on product diagnosis. Once a direction is validated, it is designed to hand off the brief to the 'product-capability' skill for implementation-ready planning.

How does Product Lens help with feature prioritization?

It uses the ICE framework—Impact, Confidence, and Effort—to rank ideas and provide a prioritized roadmap based on data rather than intuition.

Productivity & Workflow

Validates product direction and the strategic rationale behind features before development begins to ensure high-impact engineering.

Product Lens is a strategic diagnostic tool for Claude Code designed to pressure-test product ideas before they move into implementation. It shifts the focus from 'how to build' to 'why to build' by running automated diagnostics, conducting founder-level project reviews, and auditing user journeys for friction points. By utilizing data-driven frameworks like ICE scoring (Impact, Confidence, Effort), Product Lens helps teams avoid building unnecessary features and ensures that every development cycle contributes to genuine product-market fit and user value.
