7When you omit `settingSources`, `query()` reads the same filesystem settings as the Claude Code CLI: user, project, and local settings, CLAUDE.md files, and `.claude/` skills, agents, and commands. To run without these, pass `settingSources: []`, which limits the agent to what you configure programmatically. Managed policy settings and the global `~/.claude.json` config are read regardless of this option. See [What settingSources does not control](#what-settingsources-does-not-control).
