## Why Interactive `codex resume` and `codex fork` expose both a session ID positional and an initial prompt positional. With `--last`, Clap still assigns the first positional to the session ID, so a command such as `codex fork --last "/compact focus on auth"` either fails parsing or attempts to look up the prompt as a session ID instead of sending it to the latest session. This makes it impossible to select the latest session and immediately provide a follow-up prompt, even though `codex exec resume --last` already supports that workflow. <img width="1746" height="1024" alt="CleanShot 2026-06-06 at 17 00 47@2x" src="https://github.com/user-attachments/assets/86885c07-a23c-48ee-b0ee-47f2484f6eb7" /> ## What Changed - Reinterpret the first positional as the initial prompt when interactive `resume --last` or `fork --last` is used and no explicit second prompt was parsed. - Preserve the existing `resume SESSION_ID PROMPT` and `fork SESSION_ID PROMPT` behavior. - Add parser-level regression coverage for latest-session and explicit-session prompt forms. ## How to Test 1. Start an interactive session, exit it, then run `codex resume --last "continue from the latest session"`. 2. Confirm Codex resumes the latest session and submits the supplied prompt instead of treating it as a session ID. 3. Run `codex fork --last "take a different approach"`. 4. Confirm Codex forks the latest session and submits the supplied prompt. 5. Also verify `codex resume SESSION_ID "continue here"` and `codex fork SESSION_ID "branch here"` still target the explicit session and submit the prompt. Targeted tests: - `just test -p codex-cli` (267 passed)

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 want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
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
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
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.
