What is the 'investigate' mode used for?

The investigate mode is a read-only process designed for analyzing and explaining code architecture without making any changes to the files.

Can this skill automatically change my source code?

Yes, when using the 'implement' command, the skill uses the --full-auto flag to allow Codex to create, edit, or delete files based on your instructions.

Does this skill support specific code review criteria?

Yes, you can provide custom review prompts, such as focusing on security, XSS, or performance, which Codex will use to evaluate your changes.

Why does the skill wrap commands in 'script -q /dev/null'?

This ensures a TTY (teletype) environment is available, which is a technical requirement for the Codex CLI to run correctly without 'tcgetattr' errors.

Which models does this skill use?

The skill is pre-configured to use specialized models such as gpt-5.3-codex-spark to ensure high-quality coding and review results.

Productivity & Workflow

Integrates Codex CLI capabilities into Claude Code for automated code investigation, implementation, and multi-model reviews.

This skill provides a powerful bridge between Claude Code and the Codex CLI, allowing developers to delegate complex development tasks to specialized models like GPT-5-codex-spark. It automates the execution of investigation (read-only), implementation (write-enabled), and code review workflows while handling intricate terminal requirements such as TTY wrapping and sandbox configuration. By leveraging this skill, users can perform deep codebase analysis and automated file modifications through a unified interface, ensuring consistent best practices and security guardrails are applied to every AI-driven action.
