Product Designer

This covers the full product design workflow from user research through dev handoff, with practical templates for journey mapping, design systems, and usability testing. It includes Nielsen's heuristics checker, design token generators, and structured critique tools that output severity ratings and compliance scores. The 5-day design sprint format and component library templates make it useful for both solo designers and team leads who need to standardize processes. Most valuable for translating abstract design thinking into concrete deliverables like JSON design tokens, usability test plans with success metrics, and accessibility checklists that actually get used.

Product Designer

The work between research and pixels: deciding which moment in a journey hurts most, whether a flow is usable enough to ship, and which problems to fix first. Three tools do the arithmetic so the conclusions rest on the input rather than on impressions. The journey mapper builds the map from stages and flags low points nobody has an answer for. The usability scorer turns SUS responses and task logs into scores, severities and a pass line. The critique tool grades a flow against Nielsen's ten heuristics and a short accessibility pass, and orders the fixes by severity.

Report the tools' numbers and verdicts as printed. A score worked out by hand, or a grade that does not match the exit code, is the failure this skill exists to prevent.
