fix: Clarify to tools the limit of the header size

[DitherDude]

Tool calls to the question tool repeatedly becuase the agent doesnt realise that the title must be 12 or less characters. This fix should (hopefully) inform the agents on how to avoid this error in the future
** I am not a prompt engineer, this is just a rough edit**

partially Fixes #8432

The following comment was made by an LLM, it may be inaccurate:

Based on my search, I found one potentially related PR:

PR #8055: fix: add header length constraint to question.txt
#8055

This appears to be directly related to PR #8429. Both PRs address header size/length constraints for the question tool. PR #8055 may have already implemented or attempted to solve the same issue regarding clarifying header size limits to tools and agents.

I'd recommend checking if PR #8055 was merged and whether it fully addresses the concerns in PR #8429, or if there are additional clarifications needed beyond what was done in that earlier PR.

#8055 fixes this.
