Rodrigo Arias Mallo, maintainer of the [Dillo](https://dillo-browser.org/) web browser, has written a
[blog post](https://dillo-browser.org/lab/human-proof/)
with a proposal on one way to ensure that a contribution is written by a human and not AI; he suggests asking new contributors to record
their programming session using asciinema. In the same way that LLMs generate patches, they can also generate the asciinema recordings themselves. Then, the contributors can lie to the reviewers pretending to have made the edits. Perhaps surprisingly, this is not a easy task for LLMs, at least from my observations. The corpus of recordings of developers making mistakes and thinking the whole process of editing a file is not as large as the corpus of FOSS programs and patches in which to train an LLM. During my very simple tests I haven't been able to generate an asciinema session that remotely resembles what I would expect from a human, and even less so from a human with a nice editor theme and editing an existing Dillo source file.
The Dillo project is not yet requiring asciinema recordings, but he said that he would like to test the theory further. LWN covered asciinema in January 2026.
