System prompt argument not working

[Aivean]

In the examples on the official site there is a way to set system prompt.

Also, in the SDK code it translates into --system-prompt and --append-system-prompt CLI arguments:

https://github.com/anthropics/claude-code-sdk-python/blob/7efa8b3987ff55c41815748b3a16ade637b0e190/src/claude_code_sdk/_internal/transport/subprocess_cli.py#L76-L81

However, claude code CLI doesn't mention anything about those arguments, and they don't seem to work.

nvm, claude code appears to respect system prompt in non-interactive mode (-p), but ignores it in the interactive mode

not sure why, but ok
