One-UI Migration Skill
Core Principle: MIGRATE, DON'T INNOVATE — 100% behavior parity with Legacy

Quick Reference
Essential Transforms
| Angular 16 | Angular 20 |
|---|---|
*ngIf="x" |
@if (x) { } |
*ngFor="let i of items" |
@for (i of items; track i.id) { } |
constructor(private x) |
inject() |
@Input() |
input() / input.required() |
@Output() |
output() |
BehaviorSubject |
signal() |
get x() |
computed() |
Validators |
OneValidators |
DDD 4-Layer Quick Decision
HTTP/Business logic? → domain/
Injects Store? → features/
Pure I/O? → ui/
Route definitions? → shell/
Forbidden Patterns
❌ Add features not in Legacy
❌ "Improve" Legacy behavior
❌ Create new API endpoints
❌ Use `any` type
❌ Use BehaviorSubject
❌ Use constructor injection
❌ Use mat-raised-button (use mat-flat-button)
❌ Use text icons (use svgIcon="icon:xxx")
❌ Add padding to page components
❌ Create new translation keys
Activation Triggers
- "migrate this component"
- "convert to standalone"
- "how should I structure this"
- "where should this go"
- "what's the pattern for"
- "check migration rules"

Migration Planning
For complex migrations, use migration-planning skill:
/one-ui-migration:plan {feature-name}
This integrates superpowers:brainstorming and superpowers:writing-plans with tool reference checklists.
See: skills/migration-planning/SKILL.md
Post-Migration Validation
Use one-ui-migration-checker agent:
"check migration for libs/mxsecurity/{feature}"

majiayu000/claude-skill-registry
agent-ops-state
Maintain .agent state files. Use at session start, after meaningful steps, and before concluding: read/update constitution/memory/focus/issues/baseline consistently.
