How does it handle session IDs?

The skill automatically captures session IDs from the filesystem or JSONL output, ensuring reliability when managing multiple parallel Codex tasks.

Can I resume a previous Codex session?

Yes, the skill supports resuming the latest session or specific sessions via session IDs, automatically maintaining the original model and sandbox settings.

How does the sandbox mode work?

You can choose between 'read-only' for analysis, 'workspace-write' for applying edits to your local files, or 'danger-full-access' for tasks requiring network or full system access.

What is the Codex skill for Claude Code?

It is a specialized skill that allows Claude to interface directly with the Codex CLI to perform advanced code analysis and automated refactoring tasks within secure sandboxes.

Does this skill support different AI models?

Yes, you can specify the model and reasoning effort (from low to xhigh) to balance speed and intelligence for your specific task requirements.

Developer Tools

Executes and manages Codex CLI sessions for advanced code analysis, refactoring, and automated editing within specialized sandboxes.

About

The Codex skill empowers Claude to leverage the Codex CLI for complex repository-level tasks, including deep code analysis and automated refactoring. It provides robust session management, allowing users to resume previous work with explicit session IDs, and offers granular control over security through multiple sandbox modes—ranging from read-only reviews to full workspace-write access. By automating the boilerplate of CLI execution and session tracking, this skill ensures a seamless and secure coding workflow for developers working on large-scale codebases.
