## Summary - Retry transient streamable HTTP failures during RMCP startup when the failure happens while sending the initialize request. - Retry transient streamable HTTP failures for tools/list, which is read-only and safe to replay. - Cover both retryable HTTP statuses and request-layer failures where no HTTP status is returned. - Surface retryable HTTP statuses from the streamable HTTP adapter as typed client errors. - Add integration coverage for initialize retry, tools/list retry, no-status request failure retry, and non-retryable initialize status. ## Root cause The observed codex_apps failures can happen before normal tool execution: RMCP startup fails while sending initialize, or the first read-only tools/list fails after startup. Retrying hosted_apps_bridge tools/call would not cover initialize and would risk replaying side-effecting tool calls. This change retries the streamable HTTP handshake itself, recreates the transport between initialize attempts, and retries only tools/list among post-initialize service operations. ## Validation - cargo fmt --package codex-rmcp-client - cargo test -p codex-rmcp-client --test streamable_http_recovery
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.
