Which models does the Codex CLI support?

It primarily focuses on the GPT-5.2 family, including variants like gpt-5.2-codex-mini for speed and gpt-5.2-codex-max for high-reasoning tasks.

What is the primary purpose of the Codex CLI Knowledge skill?

It provides Claude with specialized technical documentation to help users navigate, configure, and optimize the OpenAI Codex CLI tool for software development.

Can this skill help me set up a secure coding environment?

Yes, it includes detailed information on sandbox modes (read-only, workspace-write) and approval policies (untrusted, on-failure) to ensure safe tool execution.

Does it support information on non-OpenAI models?

Absolutely. The skill covers how to configure the Codex CLI for various providers such as Ollama, Gemini, Anthropic, and DeepSeek via standard API compatible endpoints.

What is the AGENTS.md file mentioned in the documentation?

AGENTS.md is a project-specific documentation file, similar to CLAUDE.md, that provides the agent with context about coding standards, libraries, and project-specific instructions.
