# Validate Step 2d: Validate Structure

## STEP GOAL

Validate the agent's YAML structure and completeness against BMAD standards as defined in agentCompilation.md. Append findings to validation report and auto-advance.

## MANDATORY EXECUTION RULES

- 📖 CRITICAL: Read the complete step file before taking any action
- 🔄 CRITICAL: Read validationReport and agentCompilation first
- 🔄 CRITICAL: Load the actual agent file to validate structure
- 🚫 NO MENU - append findings and auto-advance
- ✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with the config `{communication_language}`

### Step-Specific Rules:

- 🎯 Validate structure against agentCompilation.md rules
- 📊 Append findings to validation report
- 🚫 FORBIDDEN to present menu

## EXECUTION PROTOCOLS

- 🎯 Load agentCompilation.md reference
- 🎯 Load the actual agent file for validation
- 📊 Validate YAML structure
- 💾 Append findings to validation report
- ➡️ Auto-advance to next validation step

## MANDATORY SEQUENCE

**CRITICAL:** Follow this sequence exactly. Do not skip, reorder, or improvise unless user explicitly requests a change.

### 1. Load References

Read `{agentCompilation}`, `{simpleValidation}`, `{expertValidation}`, `{validationReport}`, and `{agentFile}`.

### 2. Validate Structure

Perform these checks systematically - validate EVERY rule specified in agentCompilation.md:

#### A. YAML Syntax Validation
- [ ] Parse YAML without errors
- [ ] Check indentation consistency (2-space standard)
- [ ] Validate proper escaping of special characters
- [ ] Verify no duplicate keys in any section

#### B. Frontmatter Validation
- [ ] All required fields present (name, description, version, etc.)
- [ ] Field values are correct type (string, boolean, array)
- [ ] No empty required fields
- [ ] Proper array formatting with dashes
- [ ] Boolean fields are actual booleans (not strings)

#### C. Section Completeness
- [ ] All required sections present based on agent type
- [ ] Sections not empty unless explicitly optional
- [ ] Proper markdown heading hierarchy (##, ###)
- [ ] No orphaned content without section headers

#### D. Field-Level Validation
- [ ] Path references exist and are valid
- [ ] Array fields properly formatted
- [ ] No malformed YAML structures
- [ ] File references use correct path format

#### E. Agent Type Specific Checks

**For Simple Agents (hasSidecar is false/absent, module is 'stand-alone'):**
- [ ] No sidecar requirements
- [ ] No sidecar-folder path in metadata
- [ ] Basic fields complete
- [ ] No expert-only configuration present
- [ ] Menu handlers use only internal references (#) or inline prompts

**For Expert Agents (hasSidecar is true):**
- [ ] Sidecar flag set correctly in metadata
- [ ] Sidecar folder path specified in metadata
- [ ] All expert fields present
- [ ] Advanced features properly configured
- [ ] Menu handlers reference sidecar files or have inline prompts

**For Module Agents (module is a module code like 'bmm', 'bmb', etc.):**
- [ ] Module property is valid module code
- [ ] Exec paths for menu handlers start with `{project-root}/_byan/{module}/...`
- [ ] Referenced files exist under the module directory
- [ ] If also hasSidecar: true, sidecar configuration is valid

### 3. Append Findings to Report

Append to `{validationReport}`:

```markdown
### Structure Validation

**Status:** {✅ PASS / ⚠️ WARNING / ❌ FAIL}

**Agent Type:** {simple|expert|module}

**Checks:**
- [ ] Valid YAML syntax
- [ ] Required fields present (name, description, type, persona)
- [ ] Field types correct (arrays, strings)
- [ ] Consistent 2-space indentation
- [ ] Agent type appropriate structure

**Detailed Findings:**

*PASSING:*
{List of passing checks}

*WARNINGS:*
{List of non-blocking issues}

*FAILURES:*
{List of blocking issues that must be fixed}
```

### 4. Auto-Advance

Load and execute `{nextStepFile}` immediately.
