  * It is recommended to allowlist only the APIs you use for optimal bundle size and security.
+ * 
+ * ## Security
+ * 
+ * This API has a scope configuration that forces you to restrict the programs and arguments that can be used.
+ * 
+ * ### Restricting access to the [[`open`]] API
+ * 
+ * On the allowlist, `open: true` means that the [[open]] API can be used with any URL,
+ * as the argument is validated with the `^https?://` regex.
+ * You can change that regex by changing the boolean value to a string, e.g. `open: ^https://github.com/`.
+ * 
+ * ### Restricting access to the [[`Command`]] APIs
+ * 
+ * The `shell` allowlist object has a `scope` field that defines an array of CLIs that can be used.
+ * Each CLI is a configuration object `{ name: string, command: string, sidecar?: bool, args?: boolean | Arg[] }`.
+ * 
+ * - `name`: the unique identifier of the command, passed to the [[Command.constructor | Command constructor]].
+ * If it's a sidecar, this must be the value defined on `tauri.conf.json > tauri > bundle > externalBin`.
+ * - `command`: the program that is executed on this configuration. If it's a sidecar, it must be the same as `name`.
+ * - `sidecar`: whether the object configures a sidecar or a system program.
+ * - `args`: the arguments that can be passed to the program. By default no arguments are allowed.
+ *   - `true` means that any argument list is allowed.
+ *   - `false` means that no arguments are allowed.
+ *   - otherwise an array can be configured. Each item is either a string representing the fixed argument value
+ *     or a `{ validator: string }` that defines a regex validating the argument value.
+ * 
+ * #### Example scope configuration
+ * 
+ * CLI: `git commit -m "the commit message"`
+ * 
+ * Configuration:
+ * ```json
+ * {
+ *   "scope": {
+ *     "name": "run-git-commit",
+ *     "command": "git",
+ *     "args": ["commit", "-m", { "validator": "\\S+" }]
+ *   }
+ * }
+ * ```
+ * Usage:
+ * ```typescript
+ * import { Command } from '@tauri-apps/api/shell'
+ * new Command('run-git-commit', ['commit', '-m', 'the commit message'])
+ * ```
+ * 
  * @module
