name: codex-exec description: Execute codex CLI as sub-agent for thorough code reviews (codex's specialty), alternative approaches when stuck, or complex problems requiring extended investigation. Note that inference takes significant time.

Codex Execution Skill

Command Structure

Execute codex using the following command pattern:

Copycodex exec --full-auto --sandbox read-only --cd <project_directory> "<request>"

Parameters

• --full-auto: Enables autonomous operation without manual intervention
• --sandbox read-only: Runs in safe read-only mode (no file modifications)
• --cd <directory>: Specifies the project directory to analyze
• <request>: The natural language request describing what to analyze

Execution Guidelines

1. Determine the Request

Formulate a clear, specific request. Examples:

• "Review the authentication module for security vulnerabilities"
• "Analyze the database query patterns for performance issues"
• "Explain how the user registration flow works"

2. Set Working Directory

• Default: $PWD
• Custom: User-provided path

3. Execute & Monitor

Copycodex exec --full-auto --sandbox read-only --cd /path/to/project "Your request"

Display output, progress, errors, and final results to user.

Example Usage Patterns

Code Review

Copycodex exec --full-auto --sandbox read-only --cd . "Review the recent changes for code quality and potential bugs"

Architecture Analysis

Copycodex exec --full-auto --sandbox read-only --cd . "Analyze the overall architecture and identify design patterns used"

Bug Investigation

Copycodex exec --full-auto --sandbox read-only --cd . "Investigate why the user authentication is failing intermittently"

Refactoring Suggestions

Copycodex exec --full-auto --sandbox read-only --cd . "Suggest refactoring opportunities to improve code maintainability"

Prerequisites

Ensure the codex CLI tool is installed and available in PATH:

Copywhich codex
