- **`coreTools`** (array of strings):
- **Description:** Allows you to specify a list of core tool names that should be made available to the model. This can be used to restrict the set of built-in tools. See [Built-in Tools](../core/tools-api.md#built-in-tools) for a list of core tools.
- **Description:** Allows you to specify a list of core tool names that should be made available to the model. This can be used to restrict the set of built-in tools. See [Built-in Tools](../core/tools-api.md#built-in-tools) for a list of core tools. You can also specify command-specific restrictions for tools that support it, like the `ShellTool`. For example, `"coreTools": ["ShellTool(ls -l)"]` will only allow the `ls -l` command to be executed.
- **Default:** All tools available for use by the Gemini model.
- **Example:** `"coreTools": ["ReadFileTool", "GlobTool", "SearchText"]`.
- **Example:** `"coreTools": ["ReadFileTool", "GlobTool", "ShellTool(ls)"]`.
- **`excludeTools`** (array of strings):
- **Description:** Allows you to specify a list of core tool names that should be excluded from the model. A tool listed in both `excludeTools` and `coreTools` is excluded.
- **Description:** Allows you to specify a list of core tool names that should be excluded from the model. A tool listed in both `excludeTools` and `coreTools` is excluded. You can also specify command-specific restrictions for tools that support it, like the `ShellTool`. For example, `"excludeTools": ["ShellTool(rm -rf)"]` will block the `rm -rf` command.
- **Default**: No tools excluded.
- **Example:** `"excludeTools": ["run_shell_command", "findFiles"]`.
- **Security Note:** Command-specific restrictions in
`excludeTools` for `run_shell_command` are based on simple string matching and can be easily bypassed. This feature is **not a security mechanism** and should not be relied upon to safely execute untrusted code. It is recommended to use `coreTools` to explicitly select commands
that can be executed.
- **`autoAccept`** (boolean):
- **Description:** Controls whether the CLI automatically accepts and executes tool calls that are considered safe (e.g., read-only operations) without explicit user confirmation. If set to `true`, the CLI will bypass the confirmation prompt for tools deemed safe.
