I'm not sure I follow
there is no easy way to append to the end of the file
because the tool description does say "the number after which to insert", but if Gemini is trying to do this, we should accommodate. I wonder though, is the Gemini model misinterpreting the index, thinking it's the insert-before?

The "correct" way to insert at the end is for the model to pass len(lines). We should still accommodate Gemini but I'd leave this out of the tool description, since the intention is to always use a nonnegative index.

This requires that the model knows and keeps track of the exact number of lines in the file, which I think doesn't come "for free", e.g. if the model previously only needed to see the start of the file or some rg results, or if the model modified the file since the last time it looked at it.
In any case, I think appending to a file should be easy for the model to do, but I guess it doesn't have to be using the insert command.

That's a good point and I'm all for making this easier on the model.
@baxen to your knowledge, might this impact the performance of the editor with claude? I know this tool schema closely resembles https://docs.anthropic.com/en/docs/agents-and-tools/tool-use/text-editor-tool#insert . This is a subtle instruction change but would be good to merge with high confidence in no regression.
I noticed that Gemini 2.5 Pro kept trying to use `insert` with `insert_line` set to -1. This makes sense, because: - there is no easy way to append to the end of the file - we use -1 to mean "end of file" in other contexts (`view_range`). So, let's make -1 do the expected thing!

agreed - I also noted gpt-oss:20b would do similar things, nice catch |

Sounds good, let's make it so then |
