What Ansible commands or operations can lead to unwanted repeated executions without changes in the system?

In Ansible, undesirable repeated executions without changes in the system can be caused by the following commands or operations:

• Commands that cause changes outside of Ansible control — for example, using the command or shell module without checking the state, which leads to the command being executed every time.
• Lack of idempotency checks — if the module does not support idempotency or is not configured correctly, it will perform actions on each run.
• Using command or shell for operations that can be performed with idempotent modules.

To avoid repeated changes, it is recommended to use specialized Ansible modules that support idempotency and to add state checks (creates, removes, when) to ensure that the command is executed only when necessary.
