GitHub
Three measurements. Archived public GitHub events, counting pull requests attributed to coding agents and their share of observed PRs. Daily counts from the public search API. And every documented or self-disclosed agent PR in a watch-list of repositories, collected with evidence.
Public events observed by GH Archive since 1 January 2022, counted hour by hour from GH Archive. A pull request is attributed to an agent when opened by a known agent bot account or on an agent branch prefix, and the share uses pull requests present in the same archived hours. Archive gaps can bias both counts and shares. 39,381 hours stored across 4 days.
39,190 archived hours use legacy collection rules. Pale bars include those legacy periods; current headline comparisons use only validated complete days. 2026-09 covers 194 hours so far. Pale bars mark periods with incomplete or unusually low archive coverage (fewer than 1,000 pull requests an hour where GitHub normally opens several thousand): both counts and shares may be biased.

Commits naming a tool · 2022-01 to 2025-10 · self-identified rung
Co-author trailers and “generated with” lines in commit messages, 2022-01 to 2025-10. GitHub removed commit lists from the public event feed during 2025, so this series cannot extend past that point; the search-based signature counts on the “By agent” view continue it.
