 Klod (pronounced \klod\\), a simple Go-based CLI tool for interacting with the Anthropic API
 
+## Motivation
+
+Sometimes you just need to quickly check/ask an LLM something. I basically live in the terminal so I want to avoid the context switch to a browser. Claude code on the other hand is a bit too eager to help (which has its benefits but no necessarily for your quick short messages). Therefore I quickly stiched together klod, originally in bash, still living as [./main.sh](main.sh) at the root of the project.
