## Summary Adds a dedicated `codex.sandbox_outcome` telemetry event so we can query sandbox edge outcomes without threading sandbox metadata through tool-result output types. This is meant to make sandbox failures and approved escalation retries visible in OTEL while keeping the existing `codex.tool_result` event shape focused on tool completion data. ## What changed - Adds `SessionTelemetry::sandbox_outcome(...)`, which emits `codex.sandbox_outcome` as both a log and trace event. - Records the tool name, call id, sandbox outcome, initial attempt duration, and escalated attempt duration when a retry runs. - Emits `denied` when the sandbox blocks execution and no retry is run. - Emits `timed_out` and `signal` when those sandbox errors surface from tool execution. - Emits `escalated` when the initial sandboxed attempt fails and the approved unsandboxed retry succeeds. - Adds OTEL coverage for the new event payload, including timing fields. ## Validation - `RUST_MIN_STACK=8388608 just test -p codex-core sandbox_outcome_event_records_outcome handle_sandbox_error_user_approves_retry_records_tool_decision` - `just test -p codex-otel otel_export_routing_policy_routes_tool_result_log_and_trace_events runtime_metrics_summary_collects_tool_api_and_streaming_metrics` - `just fix -p codex-core` - `just fix -p codex-otel`
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.
