not having standard way to ignore certain folders where I don't want llm to read using his grep / bash commands.

Proposed Solution

Having to ignore certain folder / files pattern that that askes claude code to not read /write can be handled via .llmignore.
It's petty much standard so I am not sure why this feature is not yet there
