+description: Validate built features through conversational UAT
+---
+
+<objective>
+Validate built features through conversational testing with persistent state.
+
+Purpose: Confirm what the agent built actually works from user's perspective. One test at a time, plain text responses, no interrogation. When issues are found, automatically diagnose, plan fixes, and prepare for execution.
+
+Output: {phase_num}-UAT.md tracking all test results. If issues found: diagnosed gaps, verified fix plans ready for /gsd-execute-phase
+</objective>
+
+<execution_context>
+@.agent/get-shit-done/workflows/verify-work.md
+@.agent/get-shit-done/templates/UAT.md
+</execution_context>
+
+<context>
+Phase: $ARGUMENTS (optional)
+- If provided: Test specific phase (e.g., "4")
+- If not provided: Check for active sessions or prompt for phase
+
+Context files are resolved inside the workflow (`init verify-work`) and delegated via `<files_to_read>` blocks.
+</context>
+
+<process>
+Execute the verify-work workflow from @.agent/get-shit-done/workflows/verify-work.md end-to-end.
+Preserve all workflow gates (session management, test presentation, diagnosis, fix planning, routing).
