IDE (Integrated Development Environment)
An IDE is a workspace that combines code editing, file navigation, terminal, debugging, and often AI chat in one application—VS Code, Cursor, Xcode, and JetBrains are examples.
AI-native IDEs add agents, diffs, and tool timelines so designers and engineers prototype real UI states instead of only static mocks.
What it means
The IDE is the primary surface where files, git, terminal, and AI harness meet; agent edits appear as diffs against real project structure, not isolated snippets.
Why designers should care
Prototyping in an IDE exposes streaming, errors, and tool logs early. Designers pairing with agents need basic IDE literacy: files, branches, accept/reject diffs, and run preview.
Example
A designer opens Cursor, describes a settings page in chat, reviews agent diffs in the editor, and runs the dev server to test loading and error states before Figma polish.
Common mistakes
- • Expecting designers to live in Figma while agents edit code they never see.
- • No preview or run command after agent generates UI.
- • IDE agent UX that hides file tree and diff review from non-engineers.
