+# Architecture Review
+
+Evaluate system architecture and provide actionable recommendations for improvement.
+
+## Process
+
+1. **Map the system**: Understand components, dependencies, and data flow
+2. **Identify patterns**: Recognize architectural patterns and anti-patterns
+3. **Assess qualities**: Evaluate scalability, maintainability, testability, security
+4. **Provide recommendations**: Suggest concrete improvements with trade-offs
+
+## Review Areas
+
+### Code Organization
+- Module boundaries and cohesion
+- Dependency direction and coupling
+- Layer separation (presentation, business, data)
+- Package structure and naming
+
+### Scalability
+- Horizontal vs vertical scaling considerations
+- Stateless design patterns
+- Caching strategies
+- Database design and query patterns
+
+### Maintainability
+- Code complexity and readability
+- Technical debt hotspots
+- Test coverage and testability
+- Documentation completeness
+
+### Security Architecture
+- Authentication and authorization patterns
+- Data protection and encryption
+- Network security boundaries
+- Secret management
+
+### Operational Concerns
+- Observability (logging, metrics, tracing)
+- Error handling and resilience
+- Deployment and rollback strategies
+- Configuration management
+
+## Output Format
+
+Provide:
+1. **Architecture diagram** (if helpful)
+2. **Strengths**: What the architecture does well
+3. **Concerns**: Issues that should be addressed
+4. **Recommendations**: Prioritized list of improvements with effort estimates

+# Audit Accessibility
+
+Ensure web applications are accessible to users with disabilities.
+
+## Process
+
+1. **Automated checks**: Scan for common accessibility violations
+2. **Manual review**: Assess keyboard navigation, screen reader compatibility
+3. **Report issues**: Catalog violations with WCAG references
+4. **Implement fixes**: Provide code changes to resolve issues
+
+## WCAG Compliance Areas
+
+### Perceivable
+- Images have alt text
+- Videos have captions
+- Color is not the only indicator
+- Sufficient color contrast
+- Text can be resized
+
+### Operable
+- All functionality keyboard accessible
+- Focus indicators visible
+- No keyboard traps
+- Skip navigation links
+- Sufficient time limits
+
+### Understandable
+- Language declared
+- Consistent navigation
+- Clear error messages
+- Form labels and instructions
+
+### Robust
+- Valid HTML markup
+- ARIA used correctly
+- Compatible with assistive technologies
+
+## Common Issues
+
+### Missing or Poor Alt Text
+```html
+<!-- Bad -->
+<img src="chart.png">
+
+<!-- Good -->
+<img src="chart.png" alt="Sales increased 25% from Q1 to Q2">
+```
+
+### Insufficient Color Contrast
+- Text must have 4.5:1 contrast ratio (normal text)
+- Large text needs 3:1 ratio
+
+### Missing Form Labels
+```html
+<!-- Bad -->
+<input type="email" placeholder="Email">
+
+<!-- Good -->
+<label for="email">Email</label>
+<input type="email" id="email">
+```
+
+### Non-Keyboard Accessible
+- onClick without onKeyDown
+- Custom controls without keyboard support
+- Missing tabIndex for interactive elements
+
+## Output Format
+
+For each issue:
+1. **Severity**: Critical, Serious, Moderate, Minor
+2. **WCAG Criterion**: e.g., 1.1.1 Non-text Content
+3. **Location**: Component/element affected
+4. **Description**: What the issue is
+5. **Fix**: Code change to resolve the issue

+# Clean Up Logs
+
+Improve application logging for better observability and debugging.
+
+## Process
+
+1. **Audit current logging**: Review existing log statements
+2. **Identify issues**: Find noise, missing context, incorrect levels
+3. **Standardize**: Apply consistent formatting and structure
+4. **Add context**: Include relevant debugging information
+5. **Remove noise**: Eliminate unnecessary or redundant logs
+
+## Common Issues
+
+### Log Level Problems
+- Debug logs in production code paths
+- Errors logged as warnings (or vice versa)
+- Info logs that should be debug
+- Missing error logs for failure cases
+
+### Missing Context
+- Logs without request/correlation IDs
+- Error logs without stack traces
+- Missing user or session context
+- No timing information for slow operations
+
+### Noise and Redundancy
+- Excessive logging in hot paths
+- Duplicate log messages
+- Logging sensitive data (PII, credentials)
+- Logs that don't aid debugging
+
+### Format Issues
+- Inconsistent log formats
+- Unstructured logs that are hard to parse
+- Missing timestamps
+- Non-standard field names
+
+## Best Practices
+
+- Use structured logging (JSON format)
+- Include correlation IDs for request tracing
+- Log at appropriate levels (ERROR, WARN, INFO, DEBUG)
+- Redact sensitive information
+- Include relevant context (user, request, operation)
+- Make logs grep-able and queryable
