design-system-migration

design-system-migration is a skill for Claude Code from Dragoon0x/everything-design-taste. It costs 19 tokens per session (268 once invoked), scanned A, original, MIT.

A guide to replacing one design system with another over time. It covers how to map old components to new ones, migrate pages, and remove the old system safely.

In plain words
What is it for?
Use it to plan component replacements, track migration work, handle missing equivalents, and check that migrated pages still look right.
Why use it?
It helps teams manage a large visual and code change without needing to replace everything at once.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-system-migration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Design System Migration

Migration Strategy

Strangler Fig Pattern

  1. New components built in new system.
  2. Old components wrapped with new system API.
  3. Gradually replace wrappers with native new components.
  4. Old system removed when no references remain.

Page-by-Page

  1. Identify the least complex page.
  2. Migrate all components on that page to new system.
  3. Move to next page in complexity order.
  4. Each page is fully migrated before moving on.

Migration Checklist

  • Inventory all existing components and their usage count.
  • Map old components to new components.
  • Identify gaps (components in old system with no new equivalent).
  • Build missing components before starting migration.
  • Create a migration guide for each component.
  • Visual regression tests for migrated pages.
  • Deprecation warnings on old components.

Timing

  • Never migrate during a feature sprint.
  • Dedicate sprints specifically for migration.
  • Celebrate milestones (10% migrated, 50%, 90%).
  • Track migration progress publicly.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
