+# Frontmatter Schema Migration Plan
+
+This document outlines the complete migration plan for moving `schemas/frontmatter.schema.json` to `schemas/frontmatter/frontmatter.schema.json`.
+
+## Overview
+
+**Old Location**: `/schemas/frontmatter.schema.json`
+**New Location**: `/schemas/frontmatter/frontmatter.schema.json`
+
+**Why?**
+- Better organization for related files (docs, examples, tests)
+- More scalable structure for future schema versions
+- Dedicated space for validation tools and utilities
+- Aligns with best practices for schema management
+
+## Impact Analysis
+
+### Files Affected: 45+
+
+#### Critical (Code Files) - Must Update First
+- `metrics/frontmatter-metrics.js` (line 63)
+- `scripts/validation/validate-frontmatter.js` (line 24)
+- `scripts/validation/__tests__/validate-frontmatter.test.js` (lines 311, 358)
+
+#### High Priority ($schema References in Frontmatter)
+- `.github/agents/wp-security-review.agent.md`
+- `.github/agents/wp-performance-audit.agent.md`
+- `.github/agents/wp-accessibility-review.agent.md`
+- `schemas/frontmatter/frontmatter.schema.json` (self-references)
+
+#### Medium Priority (Documentation Links)
+- All test README files (5 files)
+- `schemas/README.md`
+- `scripts/README.md` and `scripts/validation/README.md`
+- Instruction files in `.github/instructions/` (7 files)
+- Chatmode files (2 files)
+- Documentation files in `docs/` (multiple)
+
+#### Broken Links to Fix
+- `.github/instructions/issue-creation.instructions.md`
+- `.github/instructions/issues.instructions.md`
+- `.github/instructions/pr-creation.instructions.md`
+- `docs/README_DOCS_ARCHITECTURE.md`
+
+These use incorrect path `schema/` instead of `schemas/` - must be fixed!
+
+## Migration Steps
+
+### Phase 1: Preparation ✅ COMPLETE
+
+- [x] Audit all references to frontmatter.schema.json
+- [x] Create new folder structure
+- [x] Create validation script
+- [x] Create tests
+- [x] Create documentation
+- [x] Create examples
+- [x] Create GitHub Actions workflow
+
+### Phase 2: Schema Setup (Current)
+
+1. **Move the schema file**
+   ```bash
+   # Create backup
+   cp schemas/frontmatter.schema.json schemas/frontmatter.schema.json.backup
+
+   # Move to new location
+   mv schemas/frontmatter.schema.json schemas/frontmatter/frontmatter.schema.json
+   ```
+
+2. **Install validation dependencies**
+   ```bash
+   cd schemas/frontmatter
+   npm install
+   ```
+
+3. **Test the validation**
+   ```bash
+   # Validate schema itself
+   npm run validate:schema
+
+   # Run tests
+   npm test
+   ```
+
+### Phase 3: Update Code Files (Critical)
+
+**These MUST be updated before deployment to avoid runtime errors.**
+
+1. **Update `metrics/frontmatter-metrics.js`**
+   ```diff
+   - const schemaPath = path.join(process.cwd(), "schemas/frontmatter.schema.json");
+   + const schemaPath = path.join(process.cwd(), "schemas/frontmatter/frontmatter.schema.json");
+   ```
+
+2. **Update `scripts/validation/validate-frontmatter.js`**
+   ```diff
+   - schemaPath: path.join(__dirname, '../../schemas/frontmatter.schema.json')
+   + schemaPath: path.join(__dirname, '../../schemas/frontmatter/frontmatter.schema.json')
+   ```
+
+3. **Update `scripts/validation/__tests__/validate-frontmatter.test.js`**
+   ```diff
+   - const schemaPath = path.resolve(__dirname, '../../../schemas/frontmatter.schema.json');
+   + const schemaPath = path.resolve(__dirname, '../../../schemas/frontmatter/frontmatter.schema.json');
+   ```
+
+### Phase 4: Update Frontmatter $schema References
+
+Update all files that reference the schema in their frontmatter:
+
+**Pattern to find:**
+```bash
+grep -r '$schema.*frontmatter.schema.json' .github/
+```
+
+**Agent files:**
+```diff
+- $schema: "../frontmatter.schema.json"
++ $schema: "../schemas/frontmatter/frontmatter.schema.json"
+```
+
+**Schema self-references:**
+```diff
+- "path": "schemas/frontmatter.schema.json"
++ "path": "schemas/frontmatter/frontmatter.schema.json"
+```
+
+### Phase 5: Update Documentation Links
+
+Update all markdown links:
+
+**Pattern to find:**
+```bash
+grep -r 'frontmatter\.schema\.json' --include="*.md"
+```
+
+**Replace pattern:**
+```diff
+- [schema](../../schemas/frontmatter.schema.json)
++ [schema](../../schemas/frontmatter/frontmatter.schema.json)
+```
+
+**Files to update:**
+- `schemas/README.md`
+- `scripts/README.md`
+- `scripts/validation/README.md`
+- All test README files
+- `docs/CHATMODE-FRONTMATTER.md`
+- `.github/instructions/*.instructions.md`
+
+### Phase 6: Fix Broken Links
+
+These files incorrectly use `schema/` instead of `schemas/`:
+
+1. `.github/instructions/issue-creation.instructions.md`
+2. `.github/instructions/issues.instructions.md`
+3. `.github/instructions/pr-creation.instructions.md`
+4. `docs/README_DOCS_ARCHITECTURE.md`
+
+**Fix:**
+```diff
+- [frontmatter schema](../../schema/frontmatter.schema.json)
++ [frontmatter schema](../../schemas/frontmatter/frontmatter.schema.json)
+```
+
+### Phase 7: Update Workflow Files
+
+Update `.github/workflows/frontmatter-metrics.yml` and any other workflows that reference the schema:
+
+```diff
+- schemas/frontmatter.schema.json
++ schemas/frontmatter/frontmatter.schema.json
+```
+
+### Phase 8: Testing & Validation
+
+1. **Run validation script**
+   ```bash
+   cd schemas/frontmatter
+   npm run validate
+   ```
+
+2. **Check for broken references**
+   ```bash
+   # Search for old references
+   grep -r "schemas/frontmatter\.schema\.json" . --exclude-dir=node_modules
+
+   # Should only find in this migration doc and backup file
+   ```
+
+3. **Test code functionality**
+   ```bash
+   # Run any dependent scripts
+   node scripts/validation/validate-frontmatter.js
+   node metrics/frontmatter-metrics.js
+   ```
+
+4. **Test GitHub Actions**
+   - Create a test PR with a markdown file
+   - Verify the frontmatter-validation workflow runs
+   - Ensure it uses the new path
+
+### Phase 9: Cleanup & Documentation
+
+1. **Remove backup**
+   ```bash
+   rm schemas/frontmatter.schema.json.backup
+   ```
+
+2. **Update VSCode settings**
+
+   In `.vscode/settings.json`:
+   ```diff
+   {
+     "yaml.schemas": {
+   -    "./schemas/frontmatter.schema.json": [
+   +    "./schemas/frontmatter/frontmatter.schema.json": [
+         ".github/agents/*.md",
+         ".github/instructions/*.md",
+         ".github/prompts/*.md",
+         ".github/chatmodes/*.md",
+         "docs/*.md"
+       ]
+     }
+   }
+   ```
+
+3. **Update CHANGELOG**
+   ```markdown
+   ## [Unreleased]
+
+   ### Changed
+   - Moved frontmatter schema to dedicated subfolder for better organization
+   - Schema now at `schemas/frontmatter/frontmatter.schema.json`
+   - Added validation tools, tests, and examples in schema folder
+
+   ### Added
+   - Frontmatter validation script with CLI tool
+   - Automated schema validation via GitHub Actions
+   - Example frontmatter files for each file type
+   - Comprehensive schema documentation
+   ```
+
+4. **Announce the change**
+   - Update relevant documentation index files
+   - Post in GitHub Discussions if necessary
+   - Note in next team meeting
+
+## Automated Migration Script
+
+For bulk updates, you can use this script:
+
+```bash
+#!/bin/bash
+# migrate-schema-references.sh
+
+OLD_PATH="schemas/frontmatter.schema.json"
+NEW_PATH="schemas/frontmatter/frontmatter.schema.json"
+
+# Update code files (JavaScript)
+find . -name "*.js" -type f -not -path "*/node_modules/*" -exec sed -i "s|$OLD_PATH|$NEW_PATH|g" {} +
+
+# Update markdown files
+find . -name "*.md" -type f -not -path "*/node_modules/*" -exec sed -i "s|$OLD_PATH|$NEW_PATH|g" {} +
+
+# Update YAML files
+find . -name "*.yml" -type f -not -path "*/node_modules/*" -exec sed -i "s|$OLD_PATH|$NEW_PATH|g" {} +
+find . -name "*.yaml" -type f -not -path "*/node_modules/*" -exec sed -i "s|$OLD_PATH|$NEW_PATH|g" {} +
+
+# Fix broken links (schema/ -> schemas/frontmatter/)
+find . -name "*.md" -type f -not -path "*/node_modules/*" -exec sed -i "s|schema/frontmatter\.schema\.json|schemas/frontmatter/frontmatter.schema.json|g" {} +
+
+echo "Migration complete! Review changes with: git diff"
+```
+
+**Usage:**
+```bash
+chmod +x migrate-schema-references.sh
+./migrate-schema-references.sh
+git diff  # Review changes
+```
+
+## Rollback Plan
+
+If issues arise:
+
+1. **Quick rollback**
+   ```bash
+   # Restore from backup
+   cp schemas/frontmatter.schema.json.backup schemas/frontmatter.schema.json
+
+   # Revert git changes
+   git checkout HEAD -- .
+   ```
+
+2. **Partial rollback**
+   - Keep the new structure
+   - Create symlink for backward compatibility:
+   ```bash
+   ln -s frontmatter/frontmatter.schema.json schemas/frontmatter.schema.json
+   ```
+
+## Verification Checklist

+# Frontmatter Schema
+
+This folder contains the unified frontmatter schema used across all LightSpeed `.github` configuration files, along with validation tools, examples, and documentation.
+
+## Overview
+
+The `frontmatter.schema.json` file is a JSON Schema (Draft 07) that validates YAML frontmatter in:
+
+- Agent specifications (`.github/agents/*.agent.md`)
+- Instructions (`.github/instructions/*.instructions.md`)
+- Prompts (`.github/prompts/*.prompt.md`)
+- Chatmodes (`.github/chatmodes/*.chatmode.md`)
+- Documentation (`docs/*.md`)
+- GitHub templates (issue, PR, discussion templates)
+- Root configuration files (`CLAUDE.md`, `GEMINI.md`, `AGENTS.md`)
+
+## Files
+
+```

+│   └── prompt.example.md
+└── tests/                     # Validation tests
+    └── schema.test.js
+```
+
+## Quick Start
+
+### Installation
+
+```bash
+cd schemas/frontmatter
+npm install
+```
+
+### Validate All Files
+
+```bash
+npm run validate
+```
+
+### Validate Specific File
+
+```bash
+node validate.js path/to/file.md
+```
+
+### Validate Schema Only
+
+```bash
+npm run validate:schema
+```
+
+## Schema Structure
+
+The schema uses JSON Schema's `oneOf` discriminator pattern with `file_type` as the discriminator property. Each file type has specific requirements:
+
+### Common Fields
+
+Available across all file types (via `$ref: "#/definitions/commonFields"`):
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `title` | string | Human-readable title |
+| `description` | string | Brief description of purpose (required for most types) |
+| `version` | string | Version string (e.g., v1.1) |
+| `created_date` | date | ISO date when file was created |
+| `last_updated` | date | ISO date of last update |
+| `author` | string | Main author or responsible party |
+| `maintainer` | string | Current maintainer or team |
+| `owners` | array | List of owners/maintainers |
+| `tags` | array | Keywords for discovery (max 8) |
+| `status` | enum | `active`, `deprecated`, `draft`, `experimental` |
+| `stability` | enum | `stable`, `experimental`, `incubating` |
+| `deprecated` | boolean | Whether this file is deprecated |
+| `replacement` | string | Path to replacement file if deprecated |
+| `domain` | enum | Primary classification domain |
+| `references` | array | AI-focused references to related files |
+
+### File Types
+
+Each `file_type` has specific required and optional fields:
+
+- **`agent`**: Agent specifications (`.github/agents/*.agent.md`)
+- **`instructions`**: Instructions files (`.github/instructions/*.instructions.md`)
+- **`prompt`**: Prompt specifications (`.github/prompts/*.prompt.md`)
+- **`chatmode`**: Chatmode configurations (`.github/chatmodes/*.chatmode.md`)
+- **`documentation`**: General docs (`docs/*.md`)
+- **`issue-template`**: GitHub issue templates
+- **`pr-template`**: GitHub PR templates
+- And more...
+
+See the schema file for complete definitions.
+
+## Usage in Files
+
+### Reference the Schema
+
+Add a `$schema` property in your YAML frontmatter:
+
+```yaml
+---
+$schema: "schemas/frontmatter/frontmatter.schema.json"
+file_type: "agent"
+name: "example-agent"
+description: "An example agent specification"
+---
+```
+
+### VSCode Integration
+
+VSCode will automatically validate YAML frontmatter if you have the YAML extension installed and the schema properly referenced.
+
+Add to `.vscode/settings.json`:
+
+```json
+{
+  "yaml.schemas": {
+    "./schemas/frontmatter/frontmatter.schema.json": [
+      ".github/agents/*.md",
+      ".github/instructions/*.md",
+      ".github/prompts/*.md",
+      ".github/chatmodes/*.md",
+      "docs/*.md"
+    ]
+  }
+}
+```
+
+## Validation
+
+### Manual Validation
+
+```bash
+# Validate all files
+npm run validate
+
+# Validate specific file
+node validate.js .github/agents/example.agent.md
+
+# Only check if schema is valid
+npm run validate:schema
+```
+
+### CI/CD Validation
+
+The validation script is integrated into GitHub Actions. See `.github/workflows/frontmatter-validation.yml`.
+
+### Pre-commit Hook
+
+To validate frontmatter before committing:
+
+```bash
+# .git/hooks/pre-commit
+#!/bin/bash
+cd schemas/frontmatter
+npm run validate
+```
+
+## Examples
+
+See the `examples/` directory for complete examples of each file type:
+
+- `agent.example.md` - Agent specification
+- `instruction.example.md` - Instructions file
+- `prompt.example.md` - Prompt specification
+
+## Testing
+
+Run the test suite:
+
+```bash
+npm test
+```
+
+## Updating the Schema
+
+When updating `frontmatter.schema.json`:
+
+1. **Edit the schema** - Make your changes following JSON Schema Draft 07 spec
+2. **Validate the schema** - Run `npm run validate:schema`
+3. **Update examples** - Ensure examples in `examples/` reflect changes
+4. **Update documentation** - Update this README and related docs
+5. **Run full validation** - Run `npm run validate` to check all files
+6. **Update version** - Increment version in schema's `title` or add a `version` field
+7. **Commit changes** - Include rationale in commit message
+8. **Update references** - If path changed, update all referencing files
+
+## Migration
+

+# WordPress REST API Security Instructions
+
+This is an example instructions file showing proper frontmatter structure for applying security guidelines to specific file patterns.
+
+## Purpose
+
+Ensure all WordPress REST API endpoints follow security best practices.
+
+## Required Security Measures
+
+### 1. Authentication
+
+All custom REST API endpoints MUST implement proper authentication:
+
+```php
+register_rest_route('myplugin/v1', '/secure-endpoint', [
+    'methods' => 'POST',
+    'callback' => 'my_secure_callback',
+    'permission_callback' => 'my_permission_check', // Required!
+]);
+```
+
+### 2. Authorization
+
+Check user capabilities before processing:
+
+```php
+function my_permission_check() {
+    return current_user_can('edit_posts');
+}
+```
+
+### 3. Input Validation
+
+Validate all input parameters:
+
+```php
+'args' => [
+    'id' => [
+        'required' => true,
+        'validate_callback' => function($param) {
+            return is_numeric($param);
+        },
+        'sanitize_callback' => 'absint',
+    ],
+],
+```
+
+### 4. Nonce Verification
+
+For sensitive operations, verify nonces:
+
+```php
+if (!wp_verify_nonce($_REQUEST['_wpnonce'], 'my_action')) {
+    return new WP_Error('invalid_nonce', 'Security check failed', ['status' => 403]);
+}
+```
+
+## Checklist
+
+- [ ] Permission callback defined (not `__return_true`)
+- [ ] User capabilities checked
+- [ ] Input validated and sanitized
+- [ ] Output escaped if returning HTML
+- [ ] Nonces verified for state-changing operations
+- [ ] Rate limiting considered for public endpoints
+- [ ] Error messages don't leak sensitive information

+
+# Generate WordPress Block Pattern
+
+This is an example prompt specification showing proper frontmatter structure.
+
+## Prompt
+
+You are a WordPress block pattern generator. Given a design specification or description, create a WordPress block pattern following WordPress coding standards and best practices.
+
+## Requirements
+
+1. **Pattern Structure**: Follow WordPress block pattern registration format
+2. **Accessibility**: Include proper ARIA labels and semantic HTML
+3. **Responsiveness**: Use WordPress responsive utilities
+4. **Internationalization**: Wrap user-facing strings in `__()` or `_e()`
+5. **Naming**: Use kebab-case for pattern slugs
+6. **Categories**: Assign to appropriate pattern categories
+
+## Expected Input
+
+User provides one of:
+
+- Design mockup or screenshot
+- Text description of desired layout
+- Example website or pattern to recreate
+- Specific blocks and arrangement
+
+## Expected Output
+
+Generate:
+
+1. Pattern registration code (PHP)
+2. Pattern metadata (title, description, categories, keywords)
+3. Block markup with proper structure
+4. Inline documentation
+
+## Example
+
+**User Input:**
+> Create a hero section with a heading, paragraph, and button in two columns
+
+**Assistant Output:**
+
+```php
+<?php
+/**
+ * Title: Hero Section Two Column
+ * Slug: mytheme/hero-two-column
+ * Categories: featured, call-to-action
+ * Description: A hero section with heading, text, and button in a two-column layout
+ * Keywords: hero, cta, columns
+ */
+?>
+<!-- wp:group {"align":"full","style":{"spacing":{"padding":{"top":"4rem","bottom":"4rem"}}},"layout":{"type":"constrained"}} -->
+<div class="wp-block-group alignfull" style="padding-top:4rem;padding-bottom:4rem">
+    <!-- wp:columns {"verticalAlignment":"center"} -->
+    <div class="wp-block-columns are-vertically-aligned-center">
+        <!-- wp:column {"verticalAlignment":"center"} -->
+        <div class="wp-block-column is-vertically-aligned-center">
+            <!-- wp:heading {"level":1} -->
+            <h1><?php esc_html_e('Welcome to Our Site', 'mytheme'); ?></h1>
+            <!-- /wp:heading -->
+
+            <!-- wp:paragraph -->
+            <p><?php esc_html_e('Discover amazing content and features.', 'mytheme'); ?></p>
+            <!-- /wp:paragraph -->
+
+            <!-- wp:buttons -->
+            <div class="wp-block-buttons">
+                <!-- wp:button -->
+                <div class="wp-block-button">
+                    <a class="wp-block-button__link">
+                        <?php esc_html_e('Get Started', 'mytheme'); ?>
+                    </a>
+                </div>
+                <!-- /wp:button -->
+            </div>
+            <!-- /wp:buttons -->
+        </div>
+        <!-- /wp:column -->
+
+        <!-- wp:column {"verticalAlignment":"center"} -->
+        <div class="wp-block-column is-vertically-aligned-center">
+            <!-- wp:image {"sizeSlug":"large"} -->
+            <figure class="wp-block-image size-large">
+                <img src="" alt="<?php esc_attr_e('Hero image', 'mytheme'); ?>"/>
+            </figure>
+            <!-- /wp:image -->
+        </div>
+        <!-- /wp:column -->
+    </div>
+    <!-- /wp:columns -->
+</div>
+<!-- /wp:group -->
+```
+
+## Validation
+
+After generation, verify:
+
+- [ ] Valid WordPress block markup
+- [ ] Proper escaping and internationalization
+- [ ] Accessibility attributes present
+- [ ] Pattern metadata complete
+- [ ] Responsive design considerations
+
+## Usage
+
+```bash
+# Via GitHub Copilot
