name: gsd-list-phase-assumptions
description: Surface Claude assumptions for phase approach before planning
allowed-tools: Read, Bash
argument-hint: '[phase]'
---
<objective>
Analyze a phase and present Claude 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

Phase number: $ARGUMENTS (required)
**Load project state first:**
@.planning/STATE.md
**Load roadmap:**
@.planning/ROADMAP.md
</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>
