Command Complexity Levels

Level 1 - Simple (Single API call, minimal parameters)

Examples:

• ec2 describe-regions
• iam list-users
• sts get-caller-identity

Time to implement: 30 minutes - 1 hour each

Level 2 - Moderate (Filtering, pagination, basic parameters)

Examples:

• ec2 describe-instances
• iam list-users --path-prefix /admin/
• s3 ls s3://bucket-name/prefix
• rds describe-db-instances

Time to implement: 1-2 hours each

Level 3 - Complex (Multiple API calls, complex logic)

Examples:

• s3 sync (requires comparison logic)
• s3 cp with multi-part upload
• ec2 run-instances (many optional parameters)
• cloudformation create-stack (template validation)

Time to implement: 4-8 hours each

Level 4 - Very Complex (State management, advanced features)

Examples:

• cloudformation update-stack (change sets)
• ecs deploy service (rolling updates)
• dynamodb query (expression parsing)
• auto-scaling group management

Time to implement: 8+ hours each

2. Using Clap for CLI argument parsing
3. Using Tokio for async operations
4. Using JSON as primary output format
5. Supporting table and text formats

Coding Standards:

1. Follow Rust naming conventions
2. Use meaningful error messages
3. Implement comprehensive logging
4. Add integration tests
5. Document all public APIs

Compatibility Goals:

1. Match Python CLI behavior for core commands
2. Support same output formats
3. Support same filtering/pagination
4. Support same configuration files
5. Support same credential chain
