## Why The rendered `<token_budget>` fragment identifies the thread and current context window, but it does not expose enough lineage to identify the first window in the thread or the immediately preceding window. Those IDs also need to remain stable across compaction, resume, and rollback. ## What changed - Track first, previous, and current UUIDv7 context-window IDs in auto-compaction state. - Render `thread_id`, `first_window_id`, `previous_window_id`, and the current window ID in the full `<token_budget>` fragment. - Persist the first and previous window IDs in compacted rollout checkpoints and restore them during rollout reconstruction. - Preserve compatibility with older compacted records that do not contain the new optional fields. - Update focused state, rendering, reconstruction, rollback, and serialization coverage. ## Validation - `just test -p codex-core token_budget` - `just test -p codex-protocol compacted_item::tests` - `just test -p codex-core tracks_prefill_and_window_boundaries` - `just test -p codex-core reconstruct_history_uses_replacement_history_verbatim` - `just test -p codex-core thread_rollback_restores_cleared_reference_context_item_after_compaction`
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.
