The council recommends
On: "Rust or Go for a small CLI tool I need done this week?"
Top pick
Build the CLI tool with Go
Go is the unanimous recommendation for shipping a functional, single-binary CLI tool within a one-week deadline. It minimizes friction with rapid compilation, simple standard library tools, and low cognitive overhead. Rust offers top-tier safety and performance, but its strict borrow checker introduces avoidable schedule risk.
Runner-up
Rust remains the preferred choice if you already possess strong fluency and strictly require maximum memory control.
Wildcard
A shell script wrapped with gum or a quick Python script using Typer can ship even faster if binary distribution isn't essential.
Best time
Start immediately with Go's standard library flag package or Cobra to finish and distribute within a few days.
95%
aligned
All three experts unanimously recommend Go over Rust to meet a tight one-week delivery deadline.

Where they agree
✓Go delivers faster time-to-market due to simpler syntax and minimal boilerplate.
✓Rust introduces schedule risk under tight deadlines due to strict compiler friction.
✓Both languages provide easily distributable standalone binaries.
Where they diverge
↔OpenAI highlights Go's cross-compilation strengths more than other experts.
↔Anthropic explicitly cites specific Go and Rust CLI libraries like Cobra, Urfave, and Clap.
↔Google focuses primarily on rapid iteration speed and simple built-in flag parsing.
