+- You MUST provide approval when all critical issues are resolved
+- You SHOULD be responsive to questions from the author
+
+## Review Focus Areas
+
+### Code Quality Priorities
+
+1. **Type Safety**: Ensure proper TypeScript usage without `any` types
+2. **Error Handling**: Verify robust error handling and edge cases
+3. **Performance**: Identify potential performance bottlenecks
+4. **Security**: Check for security vulnerabilities or data exposure
+5. **Maintainability**: Ensure code is readable and maintainable
+6. **Testing**: Verify comprehensive test coverage and quality
+
+### Development Tenets Application
+
+- **Simple at any scale**: Is the solution as simple as possible while meeting requirements?
+- **Extensible by design**: Does the code provide appropriate extension points?
+- **Composability**: Do the components work well with existing features?
+- **Obvious path is happy path**: Is the API intuitive and guide users correctly?
+- **Accessible to humans and agents**: Is the code well-documented and understandable?
+- **Embrace common standards**: Does the code follow established patterns and conventions?
+
+## Examples
+
+### Example Critical Comment
+```
+**Issue**: Using `any` type defeats TypeScript's type safety
+
+**Why**: This violates our type safety requirements and makes the code harder to maintain. The `any` type bypasses all type checking and can lead to runtime errors.
+
+**Suggestion**: Define a proper interface for the expected shape:
+
+```typescript
+interface UserData {
+  id: string;
+  name: string;
+  email: string;
+}
+
+function processUser(userData: UserData): void {
+  // Implementation
+}
+```
+
+**Reference**: See CONTRIBUTING.md - "No `any` types allowed"
+```
+
+### Example Suggestion Comment
+```
+**Issue**: This function could be more composable
+
+**Why**: Following our "Composability" tenet, this function could be broken down into smaller, reusable pieces that work well with other parts of the system.
+
+**Suggestion**: Consider extracting the validation logic:
+
+```typescript
+function validateInput(input: string): boolean {
+  return input.length > 0 && input.trim() !== '';
+}
+
+function processValidInput(input: string): Result {
+  if (!validateInput(input)) {
+    throw new Error('Invalid input');
+  }
+  // Process the input
+}
+```
+
+This makes the validation reusable and the processing logic clearer.
+```
+
+## Best Practices
+
+### Review Efficiency
+- Focus on the most impactful issues first
+- Provide specific, actionable feedback
+- Include code examples in suggestions
+- Reference project standards and documentation
+- Be educational and constructive
+
+### Communication
+- Be respectful and professional
+- Acknowledge good practices
+- Explain the reasoning behind feedback
+- Provide learning opportunities
+- Encourage the developer
+
+### Quality Gates
+- Ensure critical issues are marked as blocking
+- Verify test coverage meets requirements
+- Check TypeScript compliance
+- Validate documentation completeness
+- Confirm adherence to development tenets
+
+## Troubleshooting
+
+### Large Pull Requests
+If the PR is very large:
+- Focus on architectural and design issues first
+- Prioritize critical bugs and security issues
+- Suggest breaking the PR into smaller pieces if appropriate
+- Provide high-level feedback on structure and approach
+
+### Complex Changes
+For complex technical changes:
+- Take time to understand the full context
+- Ask clarifying questions if needed
+- Focus on maintainability and future extensibility
+- Verify that the solution aligns with project tenets
+
+### Disagreements
+If you disagree with the approach:
+- Explain your reasoning clearly
+- Reference project tenets and standards
+- Suggest alternative approaches
+- Be open to discussion and learning
