<objective>
Analyze a phase and present Claude's assumptions about technical approach, implementation order, scope boundaries, risk areas, and dependencies.
Purpose: Help users see what Claude thinks BEFORE planning begins - enabling course correction early when assumptions are wrong.
Output: Conversational output only (no file creation) - ends with "What do you think?" prompt

1. Validate phase number argument (error if missing or invalid)
2. Check if phase exists in roadmap
3. Follow phase-assumptions.md workflow:
- Analyze roadmap description
- Surface assumptions about: technical approach, implementation order, scope, risks, dependencies
- Present assumptions clearly
- Prompt "What do you think?"
4. Gather feedback and offer next steps
</process>
<success_criteria>
- Phase validated against roadmap
- Assumptions surfaced across five areas
- User prompted for feedback
- User knows next steps (discuss context, plan phase, or correct assumptions)
