Best Practices for Project Development
1. Start with Architecture
Before coding, ask OpenCode to analyze and plan:
"Analyze the requirements and propose an architecture for [project]"
2. Iterative Development
Build features incrementally:
1. Start with core functionality
2. Add error handling
3. Write tests
4. Optimize performance
5. Add documentation
3. Regular Refactoring
Keep code clean:
"Review the current implementation and suggest refactoring
opportunities for better maintainability"
4. Documentation First
Generate docs alongside code:
"As you implement each feature, also create:
- API documentation
- Code comments
- Usage examples
- Architecture decision records"
