| Who writes it | 8.2% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot | 1.5% of its commits signed by AI. With Claude Code |
| Activity | Last push November 6, 2026, 3,138 commits, 41,668 stars | Last push November 7, 2026, 65 commits, 34,122 stars |
| Tests | 1,410 test files. 56.1% of its code files have a test that imports them | 19 test files. 1.1% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
