**Theater CLI Modernization - Change Request**
The primary change request documenting the complete modernization of the Theater CLI from a hacky implementation to a professional, extensible tool. Includes:
- **Problem Statement**: Current architectural issues
- **Solution Overview**: Modern CLI patterns and architecture
- **Implementation Plan**: 3-phase rollout strategy
- **Completed Changes**: Configuration, error handling, client layer, output system
- **Remaining Work**: Command modernization, advanced features
- **Testing Strategy**: Unit, integration, and compatibility testing
- **Success Metrics**: Developer experience, user experience, maintainability
**Status**: Phase 1 Foundation Complete, Phase 2 In Progress
## Quick Reference
### Phase 1: Foundation ✅
- [x] Configuration management system (`src/config.rs`)
- [x] Modern error handling (`src/error.rs`)
- [x] Robust client layer (`src/client/`)
- [x] Rich output system (`src/output/`)
- [x] Async-first architecture (`src/lib.rs`, `src/main.rs`)
### Phase 2: Command Modernization 🚧
- [ ] Convert all commands to async pattern
- [ ] Add progress indicators
- [ ] Enhanced input validation
- [ ] Interactive prompts
### Phase 3: Advanced Features 📋
- [ ] Configuration management commands
- [ ] Shell completion support
- [ ] Plugin system architecture
- [ ] Interactive TUI mode
## Contributing
When making changes to the CLI:
1. **Update the relevant change request** with progress
2. **Document new patterns** in implementation notes
3. **Add test cases** following the established patterns
4. **Maintain backward compatibility** unless explicitly breaking
