## How we know

Every AI coding tool leaves its signature in the commits it makes: a Co-Authored-By line, its own author name, or the merge of its branch. SeeRepo reads those signatures in the repo's history; a commit without one counts as made by people, and merges don't count.

Every AI tool SeeRepo recognizes: https://seerepo.com/agents
