## Why `start_new_context_window` independently replaced in-memory history and persisted a compacted checkpoint instead of using the shared compacted-history path. That bypassed the centralized missing-item-ID assignment when `item_ids` is enabled, so fresh context messages could enter the new context window and its persisted replacement history without IDs. This follows up on the token-budget compaction reset flow introduced in [#29743](https://github.com/openai/codex/pull/29743). ## What changed - Delegate new context-window installation to `replace_compacted_history`. - Reuse its ID assignment, in-memory replacement, world-state baseline, checkpoint persistence, turn-context persistence, and session-start bookkeeping. - Add focused coverage that verifies generated IDs are present in live history and preserved in the persisted replacement history. ## Testing - `just test -p codex-core start_new_context_window_assigns_and_persists_item_ids` - `just test -p codex-core new_context_tool_starts_new_window_before_follow_up`
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.
