+<objective>
+Restore complete project context and resume work seamlessly from previous session.
+
+Routes to the resume-project workflow which handles:
+
+- STATE.md loading (or reconstruction if missing)
+- Checkpoint detection (.continue-here files)
+- Incomplete work detection (PLAN without SUMMARY)
+- Status presentation
+- Context-aware next action routing
+  </objective>
+
+<execution_context>
+@.agent/get-shit-done/workflows/resume-project.md
+</execution_context>
+
+<process>
+**Follow the resume-project workflow** from `@.agent/get-shit-done/workflows/resume-project.md`.
+
+The workflow handles all resumption logic including:
+
+1. Project existence verification
+2. STATE.md loading or reconstruction
+3. Checkpoint and incomplete work detection
+4. Visual status presentation
+5. Context-aware option offering (checks CONTEXT.md before suggesting plan vs discuss)
+6. Routing to appropriate next command
+7. Session continuity updates
