[BUG] Claude doesn't respect hard rules to not NEVER use python for its script

What's Wrong?

I have this in my home ~/.claude/CLAUDE.md, this was added by claude itself. Yet, claude doesn't even respect those and choose to use python or python3 !

This is bad because I can't audit a python script before claude runs it.

## Hard Rules

- **Scripting**: ALWAYS use Java or Kotlin (with jbang) for any non-trivial script. Simple one-liners or low-complexity shell commands (e.g., `grep`, `sed`, `find`, `curl`) are acceptable, but anything with logic, loops, or data processing must be Java or Kotlin.

## Tools & Workflows

### Preferred Tools
- **Scripting** details:
  - Use a Java 25 distribution (likely already available via `mise`)
  - For Kotlin:
    - use libraries as needed (e.g., kotlin dataframe)
    - `jbang` can run `.kt` files directly, do not mix with Kotlin scripting, e.g. `.main.kts` files
  - Prefer the use of `mise` to select an installed JDK

What Should Happen?

It should respect my enforced rules !
