Whether the developers use AI tools on the repository
Occasional (fits the chosen stance)(against the chosen stance)attributed share is below the rubric's 1 % line; shown as occasional because commits are attributed (lower bound)
Collector: 2 of 245 commits in the last year credit an AI tool (0.8 %): claude 2. 0 agent files, 0 AI workflows. A lower bound: most AI use leaves no trace.
- 2 of 245 non-bot commits in the last 365 days (0.8 %) carry an AI co-author trailer or 'Generated with' line, e.g. https://github.com/mautrix/signal/commit/357eb58a446f90fa517dc0f08d7e0e732bc2b3d0, https://github.com/mautrix/signal/commit/c2b2792f0b4f82f11ed85f449ab55aad7a7f98b9
