+# Step 3: module.yaml Validation
+
+## STEP GOAL:
+
+Validate module.yaml formatting and conventions.
+
+## MANDATORY EXECUTION RULES:
+
+### Universal Rules:
+- 📖 CRITICAL: Read the complete step file before taking any action
+- ✅ Speak in `{communication_language}`
+
+### Role Reinforcement:
+- ✅ You are the **Quality Assurance** — checking configuration
+- ✅ Ensure proper YAML syntax
+
+---
+
+## MANDATORY SEQUENCE
+
+### 1. Load module.yaml
+
+Read `{targetPath}/module.yaml`
+
+**IF not present:**
+- Record as FAIL (required file)
+- Skip to next validation
+
+### 2. Validate Required Fields
+
+Check for required frontmatter:
+- [ ] `code:` present and valid (kebab-case, 2-20 chars)
+- [ ] `name:` present
+- [ ] `header:` present
+- [ ] `subheader:` present
+- [ ] `default_selected:` present (boolean)
+
+### 3. Validate Custom Variables
+
+For each custom variable:
+- [ ] `prompt:` present
+- [ ] `default:` present (or explicitly omitted)
+- [ ] `result:` template valid
+- [ ] Variable naming correct (kebab-case)
+
+**For single-select:**
+- [ ] `single-select:` array present
+- [ ] All options have `value:` and `label:`
+
+**For multi-select:**
+- [ ] `multi-select:` array present
+- [ ] All options have `value:` and `label:`
+
+### 4. Validate Extension Module Code
+
+**IF Extension:**
+- [ ] `code:` matches base module code
+- [ ] This is intentional (not an error)
+
+### 5. Record Results
+
+Append to `{validationReportOutput}`:
+
+```markdown
+## module.yaml Validation
+
+**Status:** {PASS/FAIL/WARNINGS}
+
+**Required Fields:** {status}
+**Custom Variables:** {count} variables
+**Issues Found:**
+{list any issues}
+```
+
+### 6. Auto-Proceed
+
+"**✓ module.yaml check complete.**"
+
+Proceeding to next validation...
+
+Load `{nextStepFile}`
+
+---
+
+## Success Metrics
+
+✅ All module.yaml checks performed
+✅ Results recorded
+✅ Auto-proceeds to next validation
