Design vs Docs & Writing · both proven

design-system vs writing-plans

Both skills were run through Claude twice: once on a fixed brief without the skill, once with it. The briefs differ because each is written for the job the skill claims to do, so compare each skill against its own baseline, then decide which difference matters for your work. They are in different categories, so this is a choice of job, not a head-to-head on the same job.

design-system

Token architecture, component specifications, and slide generation. Three-layer tokens (primitive→semantic→component), CSS variables, spacing/typography scales, component specs, strategic slide creation. Use for design tokens, systematic design, brand-compliant presentations.

Brief: “Write the implementation plan for adding team accounts to a solo-user invoicing SaaS (Next.js, Postgres, Stripe): users must be able to create a team, invite members by email, assign owner or member roles, and share clients and invoices within the team, with billing moving from the user to the team. Present the plan as a single HTML page.”
