Claude Code Settings Helper

VS Code extension providing IntelliSense, JSON schema validation, and settings override visualization for Claude Code configuration files.

Features

IntelliSense & Autocomplete

Get intelligent suggestions for all Claude Code settings as you type, including:

• Model configuration
• Permission rules (allow, deny, ask)
• Sandbox settings
• Hooks configuration
• MCP server settings
• Environment variables
• And more

JSON Schema Validation

Instant validation against the Claude Code settings schema with helpful error messages for:

• Invalid property names
• Incorrect value types
• Missing required fields
• Deprecated settings

Override Visualization

Claude Code settings follow a precedence hierarchy. This extension shows you:

• Which settings are being overridden by higher-precedence files
• Which settings are overriding lower-precedence files
• The effective value that Claude Code will actually use

CodeLens Indicators

Inline indicators appear above settings to show:

• Overrides: User - This setting overrides a value from your user settings
• Overridden by: Local - This setting is overridden by a local settings file

Quick Navigation

Jump between settings files at different levels:

• Open user settings (~/.claude/settings.json)
• Open project settings (.claude/settings.json)
• Open local settings (.claude/settings.local.json)
• Navigate directly to where a setting is defined at another level

Hover Information

Hover over any setting to see:

• Current value and level
• Effective value (what Claude Code will use)
• All levels where this setting is defined
• Override chain visualization

Settings Hierarchy

Claude Code settings are loaded from multiple locations with the following precedence (highest to lowest):

Higher-precedence settings override lower-precedence ones. For example, a setting in settings.local.json will override the same setting in settings.json.
