Basic Claude Issues / Grep, Read, Glob not being rewritten as they're not Bash commands

Gave RTK a standard review with CC latest. It doesn't rewrite the main commands Grep, Read, Glob etc. as they don't go through Bash and are their own tools. In a simple code analysis task 62/77 Bash commands went through raw, not rewritten. It's confusing because based on the readme those should have big efficiency gains. Would help to clarify the documentation.
