ANTHROPIC_API_KEY environment variable not set

Error message

ANTHROPIC_API_KEY environment variable not set

What it means

PlainLlmClient::new reads the ANTHROPIC_API_KEY environment variable to build the client; std::env::var failed (unset or non-unicode), so the client cannot authenticate. The missing environment variable is the input at fault.
