-====== OpenAI Codex CLI: Terminal CLI Agent & Codex Wiki ======
-**OpenAI Codex CLI** is an open-source terminal CLI agent built in Rust by OpenAI.((https://github.com/openai/codex|Codex CLI on GitHub)) The **Codex CLI** reads, edits, and executes code locally with optional cloud-sandboxed execution, featuring Git integration, configurable approval policies, and support for multiple execution modes. This codex wiki page serves as the community reference for the Codex CLI agent.

-===== Overview =====
-Codex CLI brings OpenAI's coding capabilities directly into the terminal. Built in Rust for performance, it operates as an autonomous agent that analyzes repositories, proposes code changes, executes them with configurable approval, and iterates based on feedback.((https://developers.openai.com/codex/cli/|Official Documentation)) It supports local, worktree (isolated Git branch), and cloud execution modes, making it suitable for everything from quick edits to complex multi-file refactors.
-===== Key Features =====
-  * **Terminal-Native** -- Runs directly in your shell; no browser or IDE required
-  * **Three Execution Modes** -- Local (current directory), Worktree (isolated Git branch), Cloud (remote sandboxed)
-  * **Built-in Git Tools** -- Diff pane with inline comments, staging/reverting chunks, code review before commits
-  * **Integrated Terminal** -- Toggle via Cmd+J; Codex reads output for validation
-  * **Approval Policies** -- ''untrusted'' (always prompt), ''on-failure'', ''on-request'', ''never'' (full auto)
-  * **TOML Configuration** -- Profiles, multiple precedence levels (CLI args > profiles > config.toml > defaults)
-  * **MCP Support** -- Manage external tool servers (add/list/get/remove/login/logout)
-  * **GitHub Actions** -- ''openai/codex-action@v1'' for CI/CD integration((https://developers.openai.com/codex/integrations/github/|GitHub Integration))
-  * **Enterprise Features** -- Enhanced capabilities for business use (v0.116.0+)
-===== Architecture =====
-Codex CLI follows an agent loop: analyze the repository, generate changes, execute with approval, and iterate on feedback. The Rust core ensures low latency and efficient resource usage.((https://github.com/openai/codex/blob/main/docs/config.md|Configuration Reference))

-===== Supported Models =====
-  * **Default** -- ''gpt-5-codex''
-  * **Switchable** -- GPT-5.4, GPT-5.3-Codex, GPT-4o, o3, and more via ''/model'' command
-  * **Custom Providers** -- Any OpenAI-compatible API (Azure, Bedrock, custom endpoints)
-Model configuration via TOML:
-<code toml>
-model = "gpt-5-codex"
-model_provider = "openai-chat-completions"
-[model_providers.openai-chat-completions]
-base_url = "https://api.openai.com/v1"
-env_key = "OPENAI_API_KEY"
-wire_api = "chat"
-</code>
-===== Installation =====
-<code bash>
-# Via npm
-npm i -g @openai/codex
-# Via Homebrew
-brew install codex
-# From source (Rust)
-cargo install codex
-# First run prompts for authentication:
-# - ChatGPT account (Plus/Pro/Business/Enterprise)
-# - or API key
-codex
-</code>
-===== CLI Usage =====
-<code bash>
-# Start interactive session
-codex
-# Switch models during session
-/model gpt-5.4
-# MCP server management
-codex mcp add docs -- docs-server --port 4000
-codex mcp list --json
-codex mcp get docs
-codex mcp remove docs
-# Use profiles
-codex --profile enterprise --model o3
-# GitHub Actions integration
-# Uses openai/codex-action@v1 in workflow YAML
