SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Codex Subagent enables hands-off execution of code-oriented tasks by delegating to the Codex CLI, allowing autonomous changes directly in a project.

Core Features & Use Cases

  • Autonomous code changes: implement, fix, or review code across a repository.
  • Investigation and debugging: root-cause analysis with access to the full codebase.
  • Session-based execution: Codex runs within a controlled session with visibility into git state and file changes.

Quick Start

Use the codex skill to start an autonomous coding task by issuing a command like: /codex fix the null pointer in utils/parser.ts

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I delegate autonomous code fixes and reviews to a CLI agent?▼

You can delegate autonomous code fixes and reviews to a CLI agent by issuing commands to Codex, which executes implementation, debugging, and investigation tasks directly within your repository's full context.

Can I run an autonomous code review using my current git state and file changes?▼

Yes, you can run an autonomous code review using your current git state. Codex operates within a session-scoped context that reflects file changes, allowing it to perform root-cause analysis and review code with full repository visibility.

How do I start an autonomous debugging task for a specific file?▼

To start an autonomous debugging task for a specific file, issue a command like /codex fix the null pointer in utils/parser.ts. Codex will autonomously investigate and apply the required code changes directly in the project.

Does the Codex CLI support sandbox mode and model selection for autonomous execution?▼

Yes, the Codex CLI supports autonomous execution with optional flags for model and sandbox configuration. This allows you to control the execution environment and underlying model when delegating code-centric tasks.

What are the limitations of using a subagent for autonomous code changes?▼

The primary limitation of using a subagent for autonomous code changes is that execution is session-scoped. While Codex has visibility into the git state and file changes, complex multi-repository tasks may exceed this isolated session context.

What is the best way to automate hands-off code implementation across a repository?▼

The best way to automate hands-off code implementation across a repository is delegating tasks to Codex. It applies autonomous changes directly to your project, handling implementation and investigation without manual intervention.
