This is a fork of OpenAI Codex CLI with custom features. Fork baseline: openai/codex rust-v0.136.0. Everything not called out below should be assumed to follow upstream Codex behavior and documentation.

brew install daulet/tap/codex

curl -fsSL https://github.com/daulet/codex/releases/latest/download/install-deb.sh | sh

git clone https://github.com/daulet/codex.git
cd codex/codex-rs
cargo build --release --bin codex
./target/release/codex

• Persistent /side conversations: side discussions are saved as real conversation branches instead of temporary scratch sessions.
• Branch-aware /tree: the tree view shows side discussions alongside normal conversation branches and can resume them.
• Branch persistence metadata: side branches keep parent thread and parent turn linkage so conversation history is no longer modeled as one flat prompt/response list.

• Transcript message copy: copy selected user prompts or assistant responses from the transcript without terminal line-wrapping artifacts. This is separate from upstream /copy, which only copies the latest assistant response.
• Fork status indicator: the status line shows [FORK daulet/codex] alongside the model and reasoning effort so fork builds are easy to distinguish from upstream builds.

• Fork release automation: GitHub Actions releases each new main commit, builds macOS and Debian artifacts, publishes GitHub Releases, and updates daulet/tap/codex.
• Fork package channels: macOS installs through brew install daulet/tap/codex; Debian and Ubuntu install through the release-hosted one-liner above.
• Additional tool usage telemetry: configured OpenTelemetry deployments receive structured tool-result events with tool metadata, duration, output size, and file-edit churn.

For general Codex usage, authentication, configuration, IDE integrations, and development docs, use the upstream resources:

• OpenAI Codex repository
• Codex documentation
• Install and build notes
