<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

<context>
Phase number: $ARGUMENTS (required)

Project state and roadmap are loaded in-workflow using targeted reads.
</context>

<process>
1. Validate phase number argument (error if missing or invalid)
2. Check if phase exists in roadmap
3. Follow list-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)
  </success_criteria>
