Pull Request Overview

Adds validation for CLI commands in sync-db to prevent infinite loops by exiting when an unrecognized command is provided.

• Defines a list of supported commands and checks process.argv[2] against it.
• Prints an error message and exits with code 1 if the command is invalid.

Comments suppressed due to low confidence (3)

src/commands/index.ts:20

• There are no tests covering the invalid command handling path; consider adding a test to verify that an unrecognized command triggers the correct error message and exit code.

if (process.argv.length >= 3 && !availableCommands.includes(process.argv[2])) {

src/commands/index.ts:21

• [nitpick] The error message lists all commands in a single line, which can be hard to scan; consider formatting them as a multi-line list or table for better readability.

await printError(`Invalid command. Please use one of the following commands: ${availableCommands.join(', ')}`);

src/commands/index.ts:6

• [nitpick] The list of commands may need to be updated elsewhere in the codebase; consider extracting availableCommands into a shared constant or configuration module to avoid duplication and ease future maintenance.

const availableCommands = [

[Copilot]

[nitpick] Destructure process.argv (e.g., const [, , command] = process.argv) for improved readability when extracting the command argument.

	const [, , command] = process.argv;
