+description: Create phases to close all gaps identified by milestone audit
+---
+
+<objective>
+Create all phases necessary to close gaps identified by `/gsd-audit-milestone`.
+
+Reads MILESTONE-AUDIT.md, groups gaps into logical phases, creates phase entries in ROADMAP.md, and offers to plan each phase.
+
+One command creates all fix phases — no manual `/gsd-add-phase` per gap.
+</objective>
+
+<execution_context>
+@.agent/get-shit-done/workflows/plan-milestone-gaps.md
+</execution_context>
+
+<context>
+**Audit results:**
+Glob: .planning/v*-MILESTONE-AUDIT.md (use most recent)
+
+Original intent and current planning state are loaded on demand inside the workflow.
+</context>
+
+<process>
+Execute the plan-milestone-gaps workflow from @.agent/get-shit-done/workflows/plan-milestone-gaps.md end-to-end.
+Preserve all workflow gates (audit loading, prioritization, phase grouping, user confirmation, roadmap updates).
