2424| `Edit` | Makes targeted edits to specific files. See [Edit tool behavior](#edit-tool-behavior) | Yes |
2525| `EndConversation` | Ends the session, in rare cases of sustained abusive input or when you ask Claude to demonstrate the tool. See [EndConversation tool behavior](#endconversation-tool-behavior) | No |
2626| `EnterPlanMode` | Switches to plan mode to design an approach before coding | No |
27| `EnterWorktree` | Creates an isolated [git worktree](https://code.claude.com/docs/en/worktrees.md) and switches into it. Pass a `path` to switch into an existing worktree instead of creating a new one. On first entry the target may be a worktree of the current repository or, in a multi-repo workspace, of a repository nested inside it. Before v2.1.203, a nested repository's worktree was rejected. A `path` outside `.claude/worktrees/` prompts for your approval before entering, since it moves the session's working directory and write access to that location. New-worktree creation and paths under `.claude/worktrees/` don't prompt. Before v2.1.206, Claude entered paths outside `.claude/worktrees/` without a prompt. From within a worktree session, or from a subagent with a pinned working directory such as [`isolation: worktree`](https://code.claude.com/docs/en/sub-agents#supported-frontmatter-fields), only the `path` form is available and the target must be under `.claude/worktrees/` of the session's repository | Yes |
27| `EnterWorktree` | Creates an isolated [git worktree](https://code.claude.com/docs/en/worktrees.md) and switches into it, or switches into an existing worktree. See [EnterWorktree tool behavior](#enterworktree-tool-behavior) | Yes |
2828| `ExitPlanMode` | Presents a plan for approval and exits plan mode | Yes |
29| `ExitWorktree` | Exits a worktree session and returns to the original directory. Not available to subagents that already run in their own working directory, such as with [`isolation: worktree`](https://code.claude.com/docs/en/sub-agents#supported-frontmatter-fields) | No |
29| `ExitWorktree` | Exits a worktree session and returns to the original directory. Not available to subagents that already run in their own working directory, such as with [`isolation: worktree`](https://code.claude.com/docs/en/sub-agents#supported-frontmatter-fields). Removed or refused once [`permissions.blockWritesOutsideWorkingDirectories`](https://code.claude.com/docs/en/settings-reference#permissions-blockwritesoutsideworkingdirectories) is on | No |
3030| `Glob` | Finds files based on pattern matching. Absent by default on macOS, Linux, and WSL. See [Glob tool behavior](#glob-tool-behavior) | No |
3131| `Grep` | Searches for patterns in file contents. Absent by default on macOS, Linux, and WSL. See [Grep tool behavior](#grep-tool-behavior) | No |
3232| `ListAgents` | Lists the agents Claude can message with `SendMessage`: subagents in the session, [agent team](https://code.claude.com/docs/en/agent-teams.md) teammates, your other local Claude Code sessions, and, while this session is connected to [Remote Control](https://code.claude.com/docs/en/remote-control.md), your [cloud sessions](https://code.claude.com/docs/en/claude-code-on-the-web.md) and your Remote Control sessions on other machines. Backs the `/list-agents` command. See [cross-session messaging](https://code.claude.com/docs/en/cross-session-messaging.md). Requires Claude Code v2.1.224 or later, and appears only in sessions where [cross-session messaging is enabled](https://code.claude.com/docs/en/cross-session-messaging.md#availability). Teammate rows and the first line showing this session's own name require v2.1.239 or later | No |

294294 * [cloud sessions](https://code.claude.com/docs/en/claude-code-on-the-web.md)
295295* **Startup mode**: not a [`--bare`](https://code.claude.com/docs/en/headless#start-faster-with-bare-mode) session. Bare mode loads only shell and file tools, so the tool is never registered there.
296296* **Provider**: not available on [Amazon Bedrock](https://code.claude.com/docs/en/amazon-bedrock.md), [Claude Platform on AWS](https://code.claude.com/docs/en/claude-platform-on-aws.md), [Google Cloud's Agent Platform](https://code.claude.com/docs/en/google-vertex-ai.md), or [Microsoft Foundry](https://code.claude.com/docs/en/microsoft-foundry.md), or on sessions signed in through a [cloud gateway](https://code.claude.com/docs/en/claude-apps-gateway).

298## EnterWorktree tool behavior
299 
300The EnterWorktree tool creates an isolated [git worktree](https://code.claude.com/docs/en/worktrees.md) and switches into it. Given a `path`, it switches into an existing worktree instead of creating a new one.
301 
302* **Which worktrees `path` can name**: on first entry the target may be a worktree of the current repository. In a repository that holds other repositories, it may also be a worktree of a repository nested inside it. Before v2.1.203, a nested repository's worktree was rejected.
303* **When you're prompted**: a `path` outside `.claude/worktrees/` prompts for your approval before entering, since it moves the session's working directory and write access to that location. New-worktree creation and paths under `.claude/worktrees/` don't prompt. Before v2.1.206, Claude entered paths outside `.claude/worktrees/` without a prompt.
304* **From inside a worktree**: from within a worktree session, only the `path` form is available and the target must be under `.claude/worktrees/` of the session's repository. The same holds for a subagent with a pinned working directory, such as [`isolation: worktree`](https://code.claude.com/docs/en/sub-agents#supported-frontmatter-fields).
305* **When the tool is missing**: once [`permissions.blockWritesOutsideWorkingDirectories`](https://code.claude.com/docs/en/settings-reference#permissions-blockwritesoutsideworkingdirectories) is on, Claude Code removes `EnterWorktree` and `ExitWorktree` or refuses calls to them. To keep working in worktrees, see [Claude has no `EnterWorktree` tool](https://code.claude.com/docs/en/worktrees#claude-has-no-enterworktree-tool).
