Recommendations for AGENTS.md aimed at Windows users

[christopherkenny]

Hi, I've been playing with your AGENTS.md a bit and had two suggestions, based on using this on Windows.

1. "Otherwise, use Rscript -e "code"." is frequently bad advice for Windows. It will very often segfault if code is more than two lines. Instead, the following seems to work well:

On Windows, do not use Rscript -e '...' for multiline or complex R code because it may segfault. Instead, write a temporary .R file and run Rscript path/to/file.R.

2. Rtools no longer needs to be updated at the same frequency, so there is no Rtools 4.6. Often, if there's a compiler failure of any kind, Codex and Claude both point to mismatched toolchains. Adding the following seems to suppress that search:

R 4.6.1 and Rtools 4.5 are correctly paired; there is no Rtools 4.6.

Both of these are oriented around fixing expensive (token-wise) side quests.

Would you mind including an example of a segfault the next time you see it? That feels like something is wrong elsewhere.
