Use LLM for simple, narrow tasks, like detecting typographic or grammar issues in documentation and comments?

Given that most contributors are not native English speakers, some quick feedback about any typos in their language may be useful. Quick feedback here may reduce force-pushes and re-review due to typo fixes. There is stuff like codespell, but it only works on a curated hard-coded list of common typos.

So I tried to use an LLM for this, by passing the git diff of the pull request to it with a system prompt to report typos (and only typos).

However, it often couldn't contain itself and hallucinated other suggestions, which were not helpful in this context, so I reverted the experiment in 4f566be.
