Real-World Scenarios: When to Choose Which
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Cascade AI agent identifies all touch points, applies changes in dependency order, and Terminal integration runs tests between edits. Review cycles drop from 2 weeks to 3 days.
One orchestrated sequence generates API endpoints, database migrations, integration tests, and API docs. Naming conventions and architecture patterns stay consistent across all.
Multi-file editing applies version and API compatibility changes across repositories in one operation. Codebase awareness prevents orphaned imports that cause post-deploy.
Supercomplete with deep context generates boilerplate following project standards. New engineers submit pull requests that pass senior review on first attempt.
