[BUG] claude tends to get stuck using find/grep/sed to READ files during Explore() tool causing many permission prompts

What's Wrong?

More than half of the time, when doing an Explore(), claude tends to use Bash(find) or Bash(grep) or Bash(sed) or some combination thereof.

Since claude is not able to detect reliably if something is a Read-only Bash() operation, you get prompted MANY times. There is no way to choose allow all like these because the pattern matching is not very good in claude, plus some commands are strung together (abc && def && ghi) or piped (abc | grep "123" | sed 1;34).

What Should Happen?

• get smarter parsing Bash() calls to reliably detect read-only
• create more built-in tools to handle more complex searching like claude tries to do
• be more emphatic in system instructions or prompt to Explore() tool to PREFER built-in tools

Partial workaround is to choose No and press tab and type "prefer built-in tools"
