Gsd:list Phase Assumptions

<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>

<process>

• Validate phase number argument (error if missing or invalid)
• Check if phase exists in roadmap
• 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?"
• 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)
