Cursor Update Cursor Settings

Updating Cursor Settings

Modify Cursor/VSCode user settings. Use this when you want to change editor settings, preferences, configuration, themes, keybindings, or any settings.json values.

Settings File Location

Before Modifying Settings

1. Read the existing settings file to understand current configuration
2. Preserve existing settings — only add/modify what the user requested
3. Validate JSON syntax before writing to avoid breaking the editor

Modifying Settings

Step 1: Read Current Settings

Read the settings file first to get current contents.

Step 2: Identify the Setting to Change

Common setting categories:

• Editor: editor.fontSize, editor.tabSize, editor.wordWrap, editor.formatOnSave
• Workbench: workbench.colorTheme, workbench.iconTheme, workbench.sideBar.location
• Files: files.autoSave, files.exclude, files.associations
• Terminal: terminal.integrated.fontSize, terminal.integrated.shell.*
• Cursor-specific: Settings prefixed with cursor. or aipopup.

Step 3: Update the Setting

1. Parse the existing JSON (handle comments — VSCode settings support JSON with comments)
2. Add or update the requested setting
3. Preserve all other existing settings
4. Write back with proper formatting (2-space indentation)

Important Notes

1. JSON with Comments: VSCode/Cursor settings.json supports comments (// and /* */). Preserve comments when possible.
2. Restart May Be Required: Some settings take effect immediately, others require reloading.
3. Workspace vs User Settings:
   • User settings: Apply globally to all projects
   • Workspace settings (.vscode/settings.json): Apply only to the current project
4. Commit Attribution: For CLI agent, modify ~/.cursor/cli-config.json. For IDE agent, it is controlled from Cursor Settings > Agent > Attribution.
