Lean Canvas

A lean canvas is a one-page business thesis that makes your assumptions about problem, customer, solution, and viability explicit and testable. Developed by Ash Maurya from Alex Osterwalder's Business Model Canvas, it is specifically adapted for startups and product teams operating under uncertainty. Nine interlocking blocks force you to articulate the whole picture at once so that changing one block's assumptions surfaces the ripple effect on the others.

This skill is a strategic hub, not a specialist tool. It produces the integrated one-page artifact and cross-links to deeper PM skills (define-problem-statement, foundation-persona, define-jtbd-canvas, develop-solution-brief, discover-competitive-analysis, measure-experiment-design) for single-block depth when needed.

Supported Modes

• content (default) produces the nine-block canvas as structured markdown.
• visual produces the markdown canvas AND writes a self-contained, attractive .html file to disk using references/html-template.html as the layout scaffold. The HTML renders the canonical Maurya nine-block layout with polished typography, subtle per-column color accents, confidence badges per block, and print-ready A3 landscape styling. No external assets or CDN dependencies: the file opens correctly in a browser with no network access.

If mode is omitted, default to content and state that fallback explicitly.
