Phase 1: DESIGN

Translate vague requests into concrete specs. If intent is ambiguous, ask ONE question.

Architecture decision tree:

Periodic alerts/reports?  → Scheduled Task
Live visual interface?    → Preview Server (dashboard)
One-time analysis?        → Inline (no build needed)
Reusable tool?            → Script in workspace

For medium+ projects, present to user BEFORE writing code:

1. Data flow — sources → processing → output
2. Architecture choice and why
3. Cost estimate — (cost/run) × frequency × 30 = monthly
4. Known limitations

Design Gate (required, blocking): After Phase 1, STOP and present a short phase plan (milestones for DESIGN/BUILD/DEBUG). Ask explicitly: "是否按这个方案进入 Phase 2 BUILD？"
