V3 CLI Modernization

Use a modular command registry pattern where each command is a class with decorators for name, category, and subcommands. Register commands in a central registry that supports aliases, fuzzy matching, and middleware execution, keeping each module under 500 lines.

Use inquirer for select, multiselect, input, and confirm prompts, dynamically imported for tree-shaking. Combine with cli-progress for progress bars during long-running tasks like workflow execution.

CLI hooks fire on command lifecycle events like start, end, and error, recording execution trajectories and rewards to a learning service. This enables intelligent suggestions and pattern storage based on past command success and performance.

Yes, a workflow orchestrator executes steps with dependency ordering, conditional evaluation, and retry policies. Workflows can be generated from user intent by matching stored patterns, with progress displayed via interactive prompts.

Monolithic files and lack of caching cause slow responses. Use a performance monitor to track execution time and memory per command, targeting under 200ms average, and decompose large files into focused modules.
