Codex CLI Subagent FAQs

Question 1

How can I monitor what the subagent is doing?

Accepted Answer

By default, the skill suppresses verbose output to keep your terminal clean, but it automatically logs everything to a unique temporary file. You can read or tail these log files at any time to debug or review the subagent's progress.

Question 2

Can I customize the model and reasoning levels for subagents?

Accepted Answer

Yes. The skill supports fine-grained control over model selection and reasoning effort (low, medium, or high). This allows you to use more powerful models for complex audits and faster, cost-effective models for simple refactors.

Question 3

When should I use a subagent instead of a normal command?

Accepted Answer

Use a subagent for complex, time-consuming tasks that might take minutes or hours to complete. It is ideal for automated migrations, security audits, or any operation where you want the AI to work independently without blocking your main workflow.

Question 4

How does this skill manage security and file access?

Accepted Answer

The skill includes configurable sandbox environments. You can restrict subagents to 'read-only' mode for audits, 'workspace-write' for refactoring, or 'danger-full-access' for tasks requiring network permissions, ensuring the AI only has the access it needs.

Question 5

What does the Codex CLI Subagent skill do?

Accepted Answer

This skill allows you to spawn and manage nested 'subagent' processes. It uses the `codex exec` command to run focused, long-running tasks in the background—such as deep code analysis or repo-wide refactors—while keeping your primary session clean.
