+# CodeRabbit Configuration Specification
+
+## Overview
+
+This document specifies the CodeRabbit v2 schema configuration for the `lightspeedwp/.github` repository. CodeRabbit provides automated code review capabilities tailored to the governance and automation nature of this repository.
+
+## Configuration Location
+
+**File**: `/.coderabbit.yml`
+
+**Schema**: [CodeRabbit v2](https://coderabbit.ai/integrations/schema.v2.json)
+
+## Validation Status
+
+✅ **Validated**: 2026-06-03 against CodeRabbit v2 schema
+
+### Previously Reported Issues (FIXED)
+
+The following unrecognized properties were reported and have been **identified and fixed**:
+
+- ~~`auto_labels`~~ (removed from schema overrides)
+- ~~`auto_assign`~~ (removed from schema overrides)
+- ~~`auto_review`~~ (removed from schema overrides)
+
+**Root Cause**: These properties were defined in:
+
+1. `/.schemas/coderabbit-overrides.v2.json` - invalid schema override requiring non-existent property
+2. `/scripts/validation/__fixtures__/valid-coderabbit.yml` - test fixture using invalid property
+
+**Resolution Applied**:
+
+1. ✅ Removed `auto_review` from schema override required fields
+2. ✅ Updated test fixture to use valid CodeRabbit v2 properties
+3. ✅ Kept `path_filters` as only required override property
+4. ✅ Validated fixture against corrected schema
+
+## Core Configuration
+
+### Internationalization
+
+```yaml
+language: "en-GB"
+inheritance: true
+```
+
+- **Language**: UK English (consistent with organisation standard)
+- **Inheritance**: Enabled for reuse across repositories
+
+### Chat Configuration
+
+```yaml
+chat:
+  auto_reply: true
+```
+
+- **Auto-reply**: Enabled for faster feedback on pull requests
+
+### Review Configuration
+
+```yaml
+reviews:
+  profile: "chill"
+  request_changes_workflow: true
+  high_level_summary: true
+  review_status: true
+  review_details: true
+  collapse_walkthrough: true
+  poem: false
+```
+
+**Review Behavior**:
+
+- **Profile**: `chill` — Reduce noise; prefer high-signal comments only
+- **Workflow Integration**: Request changes when appropriate
+- **Summary**: Generate high-level summaries of changes
+- **Status**: Display review status and details
+- **Walkthrough**: Collapse detailed walkthrough for brevity
+- **Tone**: No poems (keep professional tone)
+
+### Path Filters (Exclusions)
+
+The following paths are excluded from CodeRabbit review:
+
+```yaml
+path_filters:
+  - "!build/**"           # Compiled artifacts
+  - "!node_modules/**"    # Dependencies
+  - "!assets/css/*.map"   # Source maps
+  - "!logs/**"            # Runtime logs
+  - "!docs/drafts/**"     # Draft documentation
+  - "!.schemas/**"        # Schema definitions
+  - "!coverage/**"        # Test coverage reports
+  - "!.jest-skip/**"      # Skipped test artifacts
+```
+
+**Rationale**: Exclude generated, compiled, and non-source files to focus reviews on actual code and documentation.
+
+## Path-Specific Review Instructions
+
+The configuration includes 10 specialized review rules optimized for different file types in this governance repository:
+
+### 1. AI Assets (General) - `.github/prompts/**`
+
+**Focus**: Concise, actionable reviews respecting documented style.
+
+**Key Points**:
+
+- Prefer clear, modular prompt design
+- Link suggested fixes
+- Maintain consistency with prompt conventions
+
+### 2. Agent Specifications - `.github/agents/**`
+
+**Focus**: Correctness, completeness, and implementation status.
+
+**Validation Checklist**:
+
+- ✅ YAML frontmatter complete (version, last_updated, owners, tags, file_type, status, domain, stability, permissions)
+- ✅ Spec includes: Purpose, Operating Modes/Workflow, Dependencies, Implementation Status, Changelog
+- ✅ No `references:` frontmatter field (prohibited by CLAUDE.md)
+- ✅ Implementation files have shebang, header, and test coverage
+
+### 3. Copilot & Custom Instructions - `.github/custom-instructions.md`
+
+**Focus**: Navigability, accuracy, and cross-referencing.
+
+**Validation Checklist**:
+
+- ✅ Easy navigation and currency with org standards
+- ✅ Complete, accurate YAML frontmatter
+- ✅ Cross-references to prompts.md, agent.md, AGENTS.md, instruction files
+- ✅ Up-to-date Copilot usage documentation
+
+### 4. Prompt Library - `.github/prompts/prompts.md`
+
+**Focus**: Discoverability and dynamic indexing.
+
+**Validation Checklist**:
+
+- ✅ Documents prompt conventions and usage patterns
+- ✅ Dynamic index reference to all *.prompt.md files
+- ✅ Valid YAML frontmatter with updated date/version
+- ✅ All prompts are discoverable from index
+
+### 5. Individual Prompts - `.github/prompts/*.md`
+
+**Focus**: Clarity, structure, and completeness.
+
+**Validation Checklist**:
+
+- ✅ Clear instructions, examples, and checklist sections
+- ✅ Correct YAML frontmatter
+- ✅ Referenced in prompts index
+- ✅ Valid structure and naming conventions
+
+### 6. Portable Instructions - `instructions/**`
+
+**Focus**: Standards compliance and portability.
+
+**Validation Checklist**:
+
+- ✅ Frontmatter follows canonical pattern
+- ✅ No `references:` field (prohibited)
+- ✅ Includes: Overview, General Rules, Detailed Guidance, Examples, Validation, Cross-References
+- ✅ UK English throughout
+
+### 7. Package Configuration - `**/package.json`, `**/composer.json`
+
+**Focus**: Security, dependency management, and standards.
+
+**Package.json Checks**:
+
+- ✅ Security vulnerabilities identified
+- ✅ Scripts documented with clear names
+- ✅ Semantic versioning validation
+- ✅ DevDependencies vs dependencies separation
+
+**Composer.json Checks**:
+
+- ✅ WordPress compatibility
+- ✅ Security best practices
+- ✅ PSR-4 autoloading compliance
+- ✅ PHPCS/PHPStan compatibility
+
+### 8. Source Code - `**/*.{js,ts}`, `**/scripts/**/*.sh`
+
+**JavaScript/TypeScript**:
+
+- ✅ Linting compliance
+- ✅ Dead code and unused variables
+- ✅ Accessibility and performance
+- ✅ Test isolation and naming clarity
+
+**Shell Scripts**:
+
+- ✅ POSIX compliance
+- ✅ Error handling and exit codes
+- ✅ `set -euo pipefail` and shebang present
+- ✅ Shellcheck compliance and security
+
+### 9. GitHub Actions Workflows - `**/.github/workflows/*.yml`
+
+**Focus**: Security, best practices, and maintainability.
+
+**Security Checks**:
+
+- ✅ Least-privilege permissions at job level
+- ✅ Secrets passed via env vars, not interpolated
+- ✅ Action pinning (SHA preferred over tags)
+- ✅ No unsafe `pull_request_target` patterns
+- ✅ No unmasked sensitive outputs
+
+**Quality Checks**:
+
+- ✅ Reusable workflow patterns
+- ✅ Branch/path filters on triggers
+- ✅ DRY code with matrix strategies
+- ✅ Agent-triggered workflows use `workflow_dispatch`
+
+### 10. Templates & Documentation - Various Paths
+
+**Issue Templates** (`.github/ISSUE_TEMPLATE/*.md`):
+
+- ✅ Valid markdown syntax and clear instructions
+- ✅ YAML frontmatter with required fields
+- ✅ Accessibility considerations
+- ✅ References to related documentation
+
+**PR Templates** (`.github/PULL_REQUEST_TEMPLATE/*.md`):
+
+- ✅ Clear contributor instructions
+- ✅ Valid YAML frontmatter
+- ✅ Current with latest process
+
+**Saved Replies** (`.github/SAVED_REPLIES/**/*.md`):
+
+- ✅ Valid, actionable markdown
+- ✅ YAML frontmatter with dates
+- ✅ Referenced from index
+
+**Documentation** (`**/docs/**/*.md`):
+
+- ✅ Markdown linting compliance
