Why does the Trae setup use both Visual Studio Code settings and a project rules file?

The workspace settings control formatter behavior, while `.trae/rules/project_rules.md` gives Trae repo-level guidance for how code should be written.

Can Trae share the same committed settings file as Visual Studio Code and Cursor?

Yes. Because Trae is built on VS Code, the committed workspace settings remain the most important shared editor configuration for the team.

When does the Trae project rules file matter most?

Trae teams that lean heavily on agent-generated code usually benefit the most because the project rules file reduces the amount of style cleanup needed after generation.

Ultracite for Trae

Trae works well with Ultracite when you keep the standard VS Code workspace settings in place and add a dedicated project rules file that teaches the AI how your repo expects code to look.

Why Trae teams choose Ultracite

ByteDance's AI-powered IDE built on VS Code - the real AI engineer.

Project rules keep Trae aligned with repo standards

Trae can read a project rules file, so Ultracite can influence generated code before review instead of only after save.

Simple repo setup for an AI-heavy IDE

The integration stays lightweight because Trae still relies on the same committed VS Code settings pattern as other VS Code-based editors.

Balances generation quality with reliable formatting

Ultracite helps Trae produce code that is easier to review by combining up-front guidance with save-time fixes.

Workflow tips for Trae

Keep Ultracite present in the day-to-day Trae workflow with a few editor-specific habits, not just a one-time setup.

Generate .vscode/settings.json so Trae follows the same formatter, code actions, and TypeScript defaults as the rest of the repo.

Create .trae/rules/project_rules.md to give Trae project-level instructions that reflect Ultracite's standards.

Review the rules file whenever your team's coding expectations change so Trae stays aligned before it generates code.
