## Why The `ItemIds` path fills in missing IDs before response items are persisted and emitted as raw item events. `ResponseItem::AgentMessage` is part of that same response-item stream, but it was skipped by the missing-ID repair path, leaving agent messages without stable item IDs while messages and tool items received generated IDs. Agent messages recorded through `InterAgentCommunication` also need the generated ID to survive rollout persistence and resume. Otherwise clients can observe an `amsg_` ID for the live raw response item, then see that same persisted agent message lose its item ID after restart. ## What changed - Assign missing `ResponseItem::AgentMessage` IDs with the `amsg_` prefix. - Persist the generated item ID on `InterAgentCommunication` and replay it back into the reconstructed `ResponseItem::AgentMessage` on resume. - Keep the persisted ID out of the model-visible inter-agent message envelope. - Keep `CompactionTrigger` and `Other` skipped because they do not get generated item IDs. - Update session/protocol tests for agent-message ID assignment and resume preservation. ## Manual Testing Run the local dev build using `just c --enable item_ids` to ensure this code is exercised: https://github.com/openai/codex/blob/322e33512b2d38d38d705e2ef692a8aca50decac/codex-rs/core/src/session/mod.rs#L2713-L2715 In the `.jsonl` file, I saw entries like: ```json { "timestamp": "2026-06-24T00:44:03.098Z", "type": "inter_agent_communication", "payload": { "id": "amsg_019ef715-849a-7a50-becc-ce63c6a9c994", ``` ## Test plan - `just test -p codex-core record_inter_agent_communication_preserves_item_id_in_rollout_and_resume` - `just test -p codex-core record_inter_agent_communication_sets_turn_id_in_rollout_and_resume` - `just test -p codex-protocol inter_agent_communication_response_input_item_preserves_commentary_phase`

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.
