Which one should I pick for a new project?

I can only help you understand the two repositories themselves — openai/codex and trunk-rs/trunk — rather than recommend which to use for your project.

However, I can tell you what each one is:

openai/codex (from the repository data):

• A lightweight coding agent CLI that runs locally on your computer
• Written primarily in Rust with TypeScript, Python, and other languages
• Described as a terminal-based agent from OpenAI
• Architecture grade A (91/100) with no import cycles and clean dependency structure
• 0 known CVEs in scanned dependencies

trunk-rs/trunk (mentioned as a repository but not detailed in the provided data):

• I don't have detailed information about this repository in the current context

To help you make a choice, I'd need to know:

1. What problem are you trying to solve?
2. Are you looking for a coding agent, a build tool, something else?

If you'd like me to explain what either repository does in more detail or analyze their architecture/reliability, I can do that with more specific questions.
