Template Usage Guidelines

1. Always use intelligent context - Let the system generate smart file patterns
2. Reference specific sections - Use anchor links for modular access
3. Validate generated patterns - Ensure patterns match actual project structure
4. Combine templates strategically - Use multiple templates for comprehensive analysis
5. Cache context results - Reuse context analysis across multiple templates

Integration with Intelligent Context

All templates integrate with @~/.claude/workflows/gemini-intelligent-context.md for:

• Smart Path Detection - Automatic file targeting based on analysis type
• Technology Stack Detection - Framework and language-specific optimizations
• Domain Context Mapping - Intelligent domain-specific pattern matching
• Dynamic Prompt Enhancement - Context-aware prompt construction

For complete context detection algorithms and intelligent file targeting, see the dedicated intelligent context documentation.
