## Summary - reject HTTP(S) image URLs from the shared code-mode output-image normalization path - return a concise model-visible tool error so the model can recover on its next turn - apply the targeted rejection to both `image()` and `generatedImage()` - leave other non-empty image URL values to existing downstream handling The returned error is: > Tool call failed: remote image URLs are not supported in tool outputs. Pass a base64 data URI instead ## Why Responses Lite cannot lower a remote image URL emitted from a structured tool output. Rejecting HTTP(S) values in the Codex harness preserves the tool-call metadata and gives the model a recoverable next turn instead of invalidating the sample. ## Test coverage The regression is covered primarily by a `test_codex()` agent integration test that simulates the Responses API exchange and asserts the failed model-visible exec output. A supplemental runtime test covers both `http://` and `https://` inputs across both image output helpers. ## Test plan - `cd codex-rs && just test -p codex-code-mode` - `cd codex-rs && just test -p codex-code-mode-protocol` - `cd codex-rs && just test -p codex-core code_mode_image_helper_rejects_remote_url` - `cd codex-rs && just fmt` - `git diff --check origin/main...HEAD` Related context: https://github.com/openai/openai/pull/1022346
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.
