### What changed 1. Removed per-turn MCP selection reset in `core/src/tasks/mod.rs`. 2. Added `SessionState::set_mcp_tool_selection(Vec<String>)` in `core/src/state/session.rs` for authoritative restore behavior (deduped, order-preserving, empty clears). 3. Added rollout parsing in `core/src/codex.rs` to recover `active_selected_tools` from prior `search_tool_bm25` outputs: - tracks matching `call_id`s - parses function output text JSON - extracts `active_selected_tools` - latest valid payload wins - malformed/non-matching payloads are ignored 4. Applied restore logic to resumed and forked startup paths in `core/src/codex.rs`. 5. Updated instruction text to session/thread scope in `core/templates/search_tool/tool_description.md`. 6. Expanded tests in `core/tests/suite/search_tool.rs`, plus unit coverage in: - `core/src/codex.rs` - `core/src/state/session.rs` ### Behavior after change 1. Search activates matched tools. 2. Additional searches union into active selection. 3. Selection survives new turns in the same thread. 4. Resume/fork restores selection from rollout history. 5. Separate threads do not inherit selection unless forked.
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 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.
