feat(cli): Implement lazy loading for heavy CLI commands#396
Merged
Conversation
Heavy commands (workflow, cascade, each, ai, gui, etc.) are now only imported when actually invoked, not on every CLI call. This significantly improves startup performance. Changes: - Add LazyTyperGroup that extends Typer's group with lazy loading - Add LazyCommand placeholder that shows help without importing - Register lazy commands via global registry before app creation - Add pre-computed help strings so --help doesn't trigger imports Lazy-loaded commands: - workflow, cascade, each, run, agent, claude (execution) - ai, similar (ML/embeddings) - gdoc (external services) - gui (TUI) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Resolved conflicts: - emdx/main.py: Keep lazy loading implementation, adopt new run() with help alias - pyproject.toml: Use newer typer 0.15+ from main
