## Why Users have requested the ability to edit a goal's objective after a goal has been created. This PR exposes a new `/goal edit` command in the TUI to address this request. In the process of implementing this, I also noticed an existing bug in the goal runtime. When a goal's objective is updated through the `thread/goal/set` app server API, the goal runtime didn't emit a new steering prompt to tell the agent about the new objective. This PR also fixes this hole. ## What Changed - Adds `/goal edit` in the TUI, opening an edit box prefilled with the current goal objective. - Keeps active and paused goals in their current state, resets completed goals to active, keeps budget-limited goals budget-limited, and preserves the existing token budget. - Changes the existing `thread/goal/set` behavior so editing an objective preserves goal accounting instead of resetting it. The older reset-on-new-objective behavior was left over from before `thread/goal/clear`; clients that need to reset accounting can now clear the existing goal and create a new one. - Reuses the existing goal set API path; this does not add or change app-server protocol surface area. - Adds a dedicated goal runtime steering prompt when an externally persisted goal mutation changes the objective, so active turns receive the updated objective. ## Validation - Make sure `/goal edit` returns an error if no goal currently exists - Make sure `/goal edit` displays an edit box that can be optionally canceled with no side effects - Make sure that an edited goal results in a steer so the agent starts pursuing the new objective - Make sure the new objective is reflected in the goal if you use `/goal` to display the goal summary - Make sure that `/goal edit` doesn't reset the token budget, time/token accounting on the updated goal
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 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
Install globally with your preferred package manager:
# 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.
