This is true for prohibitions but claude.md works really well as positive documentation. I run custom mcp servers and documenting what each tool does and when to use it made claude pick the right ones way more reliably. Totally different outcome than a list of NEVER DO THIS rules though, for that you definitely need hooks or sandboxing.

Yes but this is probabilistic. Skill, documentation etc help by giving it the information it needs. You are then in the more correct probability distribution. Fine for docs, tips etc, but not good enough for mandatory things.

"more reliably" is still not "reliably".
