Product Design Knowledge Base

451 expert practices across 25 categories, grounded in established research and proven patterns. Each practice includes tags, priority (core/situational/niche), and applies_when frontmatter for precise retrieval. Match the user's situation to the router below, read the starter files, then explore the full category directory for deeper guidance.

How to Use This Skill

1. Match the user's design situation to the router table below
2. Read the 3-4 starter files listed for that situation
3. Use Glob to explore the full category directory when deeper guidance is needed (e.g., practices/forms-and-input/*.md)
4. Use priority metadata to pick files when many match: core (read first) > situational > niche
5. When a situation spans multiple categories, use Grep across practices/ to find cross-cutting practices by searching applies_when or tags in frontmatter

Every practice file includes tags, priority, and applies_when in its YAML frontmatter for targeted retrieval.
