Use Cline

Above the input box, you can use Auto-approve to configure Cline’s read/write permissions and command execution permissions. Enabling these permissions can enhance automation capabilities, but may also increase token usage, so it’s recommended to enable them only after fully understanding Cline’s behavior.Cline provides two working modes, which can be switched at the bottom of the dialog:
  • Plan mode: Focuses on information gathering, problem breakdown, and task planning without directly modifying files.
  • Act mode: Executes changes, runs commands, and completes tasks based on the plan.
