Bash is all you Need
Bash is what makes Claude Code so good.
Bash is a generic version for “code mode” or programmatic tool calling.
The bash tool allows you to:
Store the results of tool calls to files, so you can search them.
Store memory in files.
Dynamically generate scripts and call them.
Compose functionality, use unix primitives like tail, grep, cat, etc.
Use existing powerful software like ffmpeg, libreoffice, etc.
