MultiClaude: Command for Claude Code

💡 TIP: Use /ipa:spec instead to generate both SRD.md + UI_SPEC.md in one step.

This command is kept for granular control when you only need UI_SPEC.md.

Prerequisite: docs/SRD.md must exist.

User Research Integration

Before starting UI design, check for USER_RESEARCH.md:

if docs/USER_RESEARCH.md exists:
  1. Read personas and journey maps
  2. Map journey stages to screens
  3. Add "Design Rationale" to each screen
  4. Apply emotional design (CJX)
else:
  Proceed with UI design (without rationale)

For each screen, add Design Rationale section:

### S-XX: [Screen Name]

**Journey Stage:** [Discovery/Onboarding/Usage/Retention/Advocacy]
**User Emotion:** [From journey map]
**Persona:** [Which persona uses this screen]

**Design Rationale:**
- Decision 1: [Why] (addresses [pain point/goal from persona])
- Decision 2: [Why]

[Rest of screen spec...]

Example:

### S-02: Dashboard

**Journey Stage:** Usage (Engaged → Productive)
**User Emotion:** Focused, wants efficiency
**Persona:** Sarah (SaaS PM)

**Design Rationale:**
- Quick actions prominent: Sarah values speed (persona behavior)
- Data visualization: Sarah is data-driven, needs metrics at a glance
- Minimal navigation: Reduce tool-switching overhead (persona pain point)
