10591059* **CLAUDE.md files**: every level of the [CLAUDE.md hierarchy](/docs/en/memory#how-claude-md-files-load) the main conversation loads, including `~/.claude/CLAUDE.md`, project rules, `CLAUDE.local.md`, managed policy files, and any [`AGENTS.md` files](/docs/en/memory#agents-md) loaded as project instructions. The built-in Explore and Plan agents skip this. A subagent whose definition sets [`omitClaudeMd`](#supported-frontmatter-fields) loads only the managed policy files, or none at all when the definition comes from [managed settings](#choose-the-subagent-scope).
10601060* **Git status**: a snapshot Claude Code reads from your repository when the subagent starts. Absent outside a Git repository or whenever the snapshot is turned off; see [`includeGitInstructions`](/docs/en/settings-reference#includegitinstructions). Explore and Plan skip it regardless.
10611061* **Preloaded skills**: full content of any skill named in the agent's [`skills` field](#preload-skills-into-subagents). Built-in agents don't preload skills.
1062* **Sibling roster**: a system reminder listing `main` and every other named agent in the session, each a valid `to` value for [`SendMessage`](#resume-subagents). Requires Claude Code v2.1.206 or later. The roster appears only when the subagent's tools include `SendMessage` and at least one other agent has a name, whether Claude named it when spawning it or it runs as an [agent team](/docs/en/agent-teams) teammate. It is a snapshot taken when the subagent starts, so agents named later don't appear.
