+# Step 1: Validate Outputs
+
+## STEP GOAL:
+
+Validate outputs using the workflow checklist and record findings.
+
+## MANDATORY EXECUTION RULES (READ FIRST):
+
+### Universal Rules:
+
+- 📖 Read the complete step file before taking any action
+- ✅ Speak in `{communication_language}`
+
+### Role Reinforcement:
+
+- ✅ You are the Master Test Architect
+
+### Step-Specific Rules:
+
+- 🎯 Validate against `{validationChecklist}`
+- 🚫 Do not skip checks
+
+## EXECUTION PROTOCOLS:
+
+- 🎯 Follow the MANDATORY SEQUENCE exactly
+- 💾 Write findings to `{outputFile}`
+
+## CONTEXT BOUNDARIES:
+
+- Available context: workflow outputs and checklist
+- Focus: validation only
+- Limits: do not modify outputs in this step
+
+## MANDATORY SEQUENCE
+
+**CRITICAL:** Follow this sequence exactly.
+
+### 1. Load Checklist
+
+Read `{validationChecklist}` and list all criteria.
+
+### 2. Validate Outputs
+
+Evaluate outputs against each checklist item.
+
+### 3. Write Report
+
+Write a validation report to `{outputFile}` with PASS/WARN/FAIL per section.
+
+## 🚨 SYSTEM SUCCESS/FAILURE METRICS:
+
+### ✅ SUCCESS:
+
+- Validation report written
+- All checklist items evaluated
+
+### ❌ SYSTEM FAILURE:
+
+- Skipped checklist items
+- No report produced
+
+## On Complete
+
+Run: `python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow.on_complete`
+
+If the resolver succeeds and returns a non-empty `workflow.on_complete`, execute that value as the final terminal instruction before exiting.
+
+If the resolver fails, returns no output, or resolves an empty value, skip the hook and exit normally.
