Fix documentation errors for Custom Prompts named arguments and add canonical examples (#5910)
The Custom Prompts documentation (docs/prompts.md) was incomplete for
named arguments:

1. **Documentation for custom prompts was incomplete** - named argument
usage was mentioned briefly but lacked comprehensive canonical examples
showing proper syntax and behavior.

2. **Fixed by adding canonical, tested syntax and examples:**
   - Example 1: Basic named arguments with TICKET_ID and TICKET_TITLE
   - Example 2: Mixed positional and named arguments with FILE and FOCUS
   - Example 3: Using positional arguments
- Example 4: Updated draftpr example to use proper $FEATURE_NAME syntax
   - Added clear usage examples showing KEY=value syntax
   - Added expanded prompt examples showing the result
   - Documented error handling and validation requirements

3. **Added Implementation Reference section** that references the
relevant feature implementation from the codebase (PRs #4470 and #4474
for initial implementation, #5332 and #5403 for clarifications).

This addresses issue #5039 by providing complete, accurate documentation
for named argument usage in custom prompts.

npm i -g @openai/codex
or brew install --cask codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex

Codex CLI splash


Quickstart

Installing and running Codex CLI

Install globally with your preferred package manager. If you use npm:

npm install -g @openai/codex

Alternatively, if you use Homebrew:

brew install --cask codex

Then simply run codex to get started:

codex

If you're running into upgrade issues with Homebrew, see the FAQ entry on brew upgrade codex.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

  • macOS
    • Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
    • x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.

Using Codex with your ChatGPT plan

Codex CLI login

Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.

You can also use Codex with an API key, but this requires additional setup. If you previously used an API key for usage-based billing, see the migration steps. If you're having trouble with login, please comment on this issue.

Model Context Protocol (MCP)

Codex can access MCP servers. To configure them, refer to the config docs.

Configuration

Codex CLI supports a rich set of configuration options, with preferences stored in ~/.codex/config.toml. For full configuration options, see Configuration.
