A new omitClaudeMd option lets a delegated subagent run without CLAUDE.md instructions
Agent definitions and the schema used to launch a Task (a delegated subagent, a separate agent Claude Code spawns to handle part of a job) now support a boolean option called omitClaudeMd. When set, the subagent runs without loading the user's, project's, or local CLAUDE.md files, which normally supply project-specific instructions. Managed policy files still apply regardless of this setting.
This gives whoever defines an agent a way to run it with a clean slate, free of project-specific CLAUDE.md instructions that might not be relevant or could conflict with the subagent's own purpose, while still keeping organization-enforced policy in effect.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

A small documentation edit on Create custom subagents touched a line naming omitClaudeMd after this was published.
Added omitClaudeMd to agent frontmatter and --agents JSON, letting custom and plugin subagents run without user, project and local CLAUDE.md…
