Separate study: CodeRabbit follow-ups, May 25–October 11, 2026
In CodeRabbit’s May 25–October 11 audit, we found 51 original PRs crediting Claude, followed by 53 CodeRabbit auto-fix PRs; 39 follow-ups were merged. This cohort was selected through CodeRabbit, so it cannot tell us what fraction of this agent’s overall work receives follow-up fixes. Credits can name a model without identifying its client.
elizaOS/eliza: “fix(plugins): remove settings that no code reads” (merged). storytold/gridcraft: “io: remove the .sctmp temporary file when a save fails” (merged).
This is a sample of publicly attributed work, not total usage or a market-share estimate. Repositories are not customers. Attribution is declared in metadata, not independently verified tool execution; it does not prove exclusive authorship or autonomy. PR status is recorded at capture; merged does not establish correctness.
Up to 50 most recently created public PR search results within the audit window; post-filtered for body attribution or Codex branch. A recent convenience sample, not a random or exhaustive sample.

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 2026-10-18): 10.6M signed commits (+4.4% week over week), search estimate.
Distinct users: 8,849 humans opened the 12,399 most recently sampled PRs, about 1.4 PRs per person.
Merge rate: 91.6% of its pull requests get merged (6,335,925 of 6,916,377 over 8 settled weeks, 2026-08-10 to 2026-10-04). The window ends about ten days back so recently-opened PRs have had time to merge.
GitHub review activity: 3.5% of its merged PRs had at least one GitHub review record before merging; the other 96.5% 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: 29.8% of the 1999 most recent public PRs sampled (595 PRs, 2 windows, last 2026-09-27).
Task lens: 4.2M agent-opened PRs. The declared mark can be removed by the team, so treat this as approximate.
Snapshot 2026-06-09, confidence Medium, tracked since 2026-06-09. Read the methodology.
Claude Code's npm downloads halved in late April 2026 — a distribution change, not a usage decline.
In late April 2026 Anthropic moved the recommended install to native installers (Homebrew, WinGet, apt, dnf, apk). The npm package still works and installs the same binary, so the drop from ~13M to ~8M weekly is installs shifting off npm, not fewer users. npm now counts only one channel and understates total adoption.
Trailing 4-week npm average. Native installs are unobserved, so this remains a floor.
