Public GitHub commits attributed to Claude
Claude Code declares attribution on the work it produces, so coverage is strong. The headline is a point-in-time estimate that moves between measurements and a floor: squash-merges, private repositories, and a separate review integration sit outside it.
Last full week (ending 2026-10-25): 11.5M signed commits (+8.2% week over week), search estimate.
Distinct users: 8,875 humans opened the 12,600 most recently sampled PRs, about 1.4 PRs per person.
Merge rate: 91.6% of its pull requests get merged (8,764,896 of 9,573,369 over 8 settled weeks, 2026-08-24 to 2026-10-18). The window ends about ten days back so recently-opened PRs have had time to merge.
GitHub review activity: 3.6% of its merged PRs had at least one GitHub review record before merging; the other 96.4% had none. This is a broad weekly signal and can include bot reviews; the human-review read below comes from the enriched PR sample.
In significant repos (company-owned or 10+ stars), 30.5% of its merged PRs got a human review. Across all sampled repos, the rate is 20%. Human review means a non-author, non-bot GitHub reviewer in the PR-lifecycle sample. 1 sampled PRs had more than 100 review records, so those reviewer lists are marked truncated.
Median time to merge: 38 min. The unreviewed median is 0.36h. The human-reviewed median is 32.58h. From a 120-PR sample merged 2026-07-30 to 2026-08-28.
Test-inclusion: 47.5% of its sampled merged PRs touch a test file. This is a rough read on production readiness. 4 large PRs hit GitHub's 100-file path read cap, so treat this as a floor.
Flow share: 19.4% of the 1805 most recent public PRs sampled (350 PRs, 2 windows, last 2026-10-31).
Task lens: 4.2M agent-opened PRs. The declared mark can be removed by the team, so treat this as approximate.
