+description: Surface the agent's assumptions about a phase approach before planning
+---
+
+
+<objective>
+Analyze a phase and present the agent's assumptions about technical approach, implementation order, scope boundaries, risk areas, and dependencies.
+
+Purpose: Help users see what the agent 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
+</objective>

+Phase number: $ARGUMENTS (required)

+Project state and roadmap are loaded in-workflow using targeted reads.

+<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>
