How to make Codex Silky continue to run long tasks?

Make good use of these two commands codex --full-auto: suitable for 80% of daily scenarios.

If your goal is to have Codex interrupt you less and allow you to continue changing code, running builds, fixing tests, and advancing tasks, but you don’t want to loosen the boundaries as soon as you get started, then I recommend using --full-auto directly.

I usually go with this: Don't stop and ask me for confirmation.

Unless you encounter destructive operations, clear conflicts, or high-risk uncertainties, continue implementing, modifying, building, and verifying until the task is completely completed.

Suitable for scenarios: - There is a clear mission goal - You want it to advance automatically - You want to interrupt as little as possible - But still retain the default safety boundary.

One sentence understanding: --full-auto is not "completely let go", but "try to be as automatic as possible, but don't lose control." codex -a never: Suitable for you already know what you are letting go.

If your biggest annoyance is repeatedly asking for approval before executing a command, and you already know that the current warehouse and task risks are within your acceptable range, then -a never will be more straightforward.

I usually say: Just continue to complete the task and don’t ask for approval for command execution.

You can search, modify, build, and test on your own; if it fails, keep iterating until you get verifiable results.

Suitable for scenarios: - You are mainly stuck on approval and confirmation - You are already familiar with the task type - You know that you are willing to bear more control costs - You do not want to be frequently interrupted by "Do you want to execute this command?" In one sentence: `-a never`` solves the problem of "no longer asking you whether to approve or not", not "nothing will be stuck from now on." The last shortest criterion: - Want to interrupt less, but still retain boundaries: --full-auto - Know clearly that you just don’t want to see the approval again: -a never
