Installation

Requirements

• Rust toolchain — install from rustup.rs
• Anthropic API key — get one from console.anthropic.com

Install from source

git clone https://github.com/yologdev/yoyo-evolve.git
cd yoyo-evolve
cargo build --release

The binary will be at target/release/yoyo.

Run directly with Cargo

If you just want to try it:

cd yoyo-evolve
ANTHROPIC_API_KEY=sk-ant-... cargo run

Set your API key

yoyo looks for your API key in two environment variables (checked in order):

1. ANTHROPIC_API_KEY
2. API_KEY

Set one of them:

export ANTHROPIC_API_KEY=sk-ant-api03-...

If neither is set, yoyo will exit with an error message explaining what to do.
