## Why Codex Apps file parameters use a three-step upload flow: create a file record, PUT bytes to a returned signed URL, and finalize the upload. Each step still constructed a default `reqwest` client, so the flow could bypass `features.respect_system_proxy` even after model API requests honored it. This stack entry makes the resolved client policy a required input to the upload API and resolves each concrete destination independently. ## What changed - Require `HttpClientFactory` in `upload_openai_file`. - Build clients for the create, signed upload, and finalize URLs through the shared API route policy. - Pass the factory derived from the turn configuration at the Apps/MCP call site. - Return a destination-aware `ClientBuild` error when enabled route selection cannot construct a client. - Preserve the legacy logged fallback for the feature-off `ReqwestDefault` policy. ## Review guide 1. `codex-api/src/files.rs` changes the upload API and centralizes route-aware client construction. 2. The three request stages each supply their actual URL, including the separately hosted signed blob URL. 3. `core/src/mcp_openai_file.rs` is the only production caller and supplies the turn configuration factory. ## Validation - `cargo check --tests -p codex-api -p codex-core` - `just test -p codex-api files` (1 matching upload test passed; 135 tests skipped by filter) - `just fix -p codex-api -p codex-core` ## Follow-up Other direct HTTP clients remain separate migration slices. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
