**PR Summary** This PR adds embedded-only OTEL policy audit logging for `codex-network-proxy` and threads audit metadata from `codex-core` into managed proxy startup. ### What changed - Added structured audit event emission in `network_policy.rs` with target `codex_otel.network_proxy`. - Emitted: - `codex.network_proxy.domain_policy_decision` once per domain-policy evaluation. - `codex.network_proxy.block_decision` for non-domain denies. - Added required policy/network fields, RFC3339 UTC millisecond `event.timestamp`, and fallback defaults (`http.request.method="none"`, `client.address="unknown"`). - Added non-domain deny audit emission in HTTP/SOCKS handlers for mode-guard and proxy-state denies, including unix-socket deny paths. - Added `REASON_UNIX_SOCKET_UNSUPPORTED` and used it for unsupported unix-socket auditing. - Added `NetworkProxyAuditMetadata` to runtime/state, re-exported from `lib.rs` and `state.rs`. - Added `start_proxy_with_audit_metadata(...)` in core config, with `start_proxy()` delegating to default metadata. - Wired metadata construction in `codex.rs` from session/auth context, including originator sanitization for OTEL-safe tagging. - Updated `network-proxy/README.md` with embedded-mode audit schema and behavior notes. - Refactored HTTP block-audit emission to a small local helper to reduce duplication. - Preserved existing unix-socket proxy-disabled host/path behavior for responses and blocked history while using an audit-only endpoint override (`server.address="unix-socket"`, `server.port=0`). ### Explicit exclusions - No standalone proxy OTEL startup work. - No `main.rs` binary wiring. - No `standalone_otel.rs`. - No standalone docs/tests. ### Tests - Extended `network_policy.rs` tests for event mapping, metadata propagation, fallbacks, timestamp format, and target prefix. - Extended HTTP tests to assert unix-socket deny block audit events. - Extended SOCKS tests to cover deny emission from handler deny branches. - Added/updated core tests to verify audit metadata threading into managed proxy state. ### Validation run - `just fmt` - `cargo test -p codex-network-proxy` ✅ - `cargo test -p codex-core` ran with one unrelated flaky timeout (`shell_snapshot::tests::snapshot_shell_does_not_inherit_stdin`), and the test passed when rerun directly ✅ --------- Co-authored-by: viyatb-oai <viyatb@openai.com>
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 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
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.
