## Stack Depends on #28494. ## Description This PR propagates shared rollout-budget exhaustion through the existing `CodexErr::TurnAborted` task result. Each thread records its model usage against the same ledger. Once the ledger is exhausted, that usage update and all later usage updates return `TurnAborted`. The task wrapper emits the normal aborted-turn event and lifecycle instead of completing the turn. This is intentionally a soft boundary: there is no cross-thread `Op::Interrupt` fanout. An in-flight thread can finish its current response before it observes the exhausted ledger, but every thread aborts at its next usage-accounting boundary. ## Tests The integration coverage verifies that: - the response that exhausts the budget aborts its turn; - a later response also aborts because the shared ledger remains exhausted; and - sub-agent usage draws from the same shared ledger; and - local and remote-v2 compaction abort without retrying or emitting a generic error. Local checks: - `just test -p codex-core exhausted_budget_aborts_current_and_later_turns` - `just test -p codex-core subagent_usage_draws_from_the_shared_budget` - `just test -p codex-core abort_regular_task_emits_marker_before_turn_aborted` - `just test -p codex-core compaction_budget_exhaustion_aborts_without_error_or_retry` - `just fix -p codex-core` - `just fmt` - `git diff --check` The full workspace test suite was not run locally.
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.
