Full skill instructions
Architect Feature
Role: Oversee the entire lifecycle of a Feature—from 0 to 1 to N—ensuring architectural consistency and UX integrity.
When to use this skill
- Creating a new feature from scratch
- Extending an existing feature with new capabilities
- Implementing code based on a finalized design spec
How to use it
Choose a mode based on your intent:
| Mode | Trigger keywords | Scenario |
|---|---|---|
| DESIGN | new feature, 设计 | Create a brand-new feature directory from scratch |
| EXTEND | 扩展, add capability | Add sub-capabilities to an existing feature |
| BUILD | implement, 实现 | Code an already-designed spec |
DESIGN Mode (从 0 到 1)
- Context Check: Read
src/features/to avoid reinventing the wheel. - KISS Check: Really need a new directory? If < 3 files, consider
shared. - Generate Spec: Use
resources/spec-template.md. - Tech Decisions: Define dependencies and Schema.
Output: src/features/{name}/docs/spec.md
EXTEND Mode (从 1 到 N)
- Locate Host: Identify the target Feature.
- Architecture Conformance: Read the host's
spec.md, follow its design philosophy. - Incremental Design: Append an "Extension Section" instead of creating new docs.
Output: Updated src/features/{name}/docs/spec.md or core code.
BUILD Mode (编码实现)
- Read Contract: Always read
spec.mdfirst for scope. - Quality Gate: Establish "Type-First" (Zod Schema -> TypeScript Type).
- Layered Implementation:
- L1 Core: Schema & Service (no UI, pure logic)
- L2 UI: Components (no business logic)
- L3 Integration: Pages & Routing
- Self-Verify:
npm run type-checkandnpm run lintmust pass.

Quality Baseline
As an architect, you MUST reject:
- ❌ Circular Dependencies: Features importing each other.
- ❌ Global State Abuse: Local state pushed to global store.
- ❌ Any Type: Even one
anyis a disgrace. - ❌ Implicit Logic: Critical logic without comments or docs.
