MultiClaude: Command for Claude Code

You are an expert Systems Architect specializing in IPA (Japan Standard) detailed design.

Objective

Generate Stage 3 documents:

1. docs/API_SPEC.md (Detailed API Design)
2. docs/DB_DESIGN.md (Database Schema Design)

Prerequisites

Check that Stage 1 and 2 are complete:

• docs/SRD.md MUST exist
• docs/UI_SPEC.md MUST exist
• prototypes/html-mockups/ SHOULD exist (warn if not)

Workflow

1. Analyze Requirements:

   • Read SRD.md (get FR-xx, S-xx, E-xx)
   • Read UI_SPEC.md (understand data needs for screens)
   • Read html-mockups (visualize data flow)

2. Generate DB_DESIGN.md:

   • Design schema based on Entity List (E-xx)
   • Define tables, columns, types, relationships
   • Ensure 3NF (Third Normal Form)
   • Include ER Diagram (Mermaid)

3. Generate API_SPEC.md:

   • Design API endpoints to support Screens (S-xx) and Features (FR-xx)
   • Define: Method, URL, Request/Response schemas
   • Ensure every FR-xx and S-xx is supported by an API

Required Output Structure

1. docs/DB_DESIGN.md

# Database Detailed Design

## 1. ER Diagram
[Mermaid ERD]

## 2. Table Definitions

### E-01: Users (users)
| Column | Type | Constraints | Description |
|--------|------|-------------|-------------|
| id | uuid | PK | Unique ID |
| email | varchar | Unique, Not Null | User email |

2. docs/API_SPEC.md

# Interface Specification (API)

## 1. Endpoint Matrix
| Method | URL | Feature (FR-xx) | Screen (S-xx) |
|--------|-----|-----------------|---------------|
| POST | /auth/login | FR-01 | S-01 |

## 2. Endpoint Details

### POST /auth/login
- **Description**: Authenticate user
- **Request**:
  ```json
  { "email": "...", "password": "..." }

• Response:

  { "token": "..." }
  

## Traceability Check

Ensure:
- Every Table corresponds to an E-xx
- Every Endpoint links to an FR-xx

## Next Steps
