## What Record a model-visible `<turn_aborted>` marker in history when a turn is interrupted, and treat it as a session prefix. ## Why When a turn is interrupted, Codex emits `TurnAborted` but previously did not persist anything model-visible in the conversation history. On the next user turn, the model can’t tell the previous work was aborted and may resume/repeat earlier actions (including duplicated side effects like re-opening PRs). Fixes: https://github.com/openai/codex/issues/9042 ## How On `TurnAbortReason::Interrupted`, append a hidden user message containing a `<turn_aborted>…</turn_aborted>` marker and flush. Treat `<turn_aborted>` like `<environment_context>` for session-prefix filtering. Add a regression test to ensure follow-up turns don’t repeat side effects from an aborted turn. ## Testing `just fmt` `just fix -p codex-core` `cargo test -p codex-core -- --test-threads=1` `cargo test --all-features -- --test-threads=1` --------- Co-authored-by: Skylar Graika <sgraika127@gmail.com> Co-authored-by: jif-oai <jif@openai.com> Co-authored-by: Eric Traut <etraut@openai.com>

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.
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.
