1.2%1 / 81 sampled commits
1 of 81 unique sampled commits carry additional agent attribution (Claude). Counting each agent separately can therefore count the same commit more than once. This is shared attribution, not proof of a handoff or which tool did most of the work.
56.8%46 / 81 sampled commits
Ashahell/ReIncarnation accounts for 46 of the 81 distinct attributed commits returned. This makes the sample useful for studying that project’s workflow, but unsuitable as a picture of the agent’s wider adoption.
jalfern/retrogames: “Zork: the agent exhausts the map honestly instead of deadlocking in a one-exit room (#146)”. Talqo/talqo: “perf(widget): embed from one non-blocking self-contained script tag (#79)”.
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. GitHub flagged incomplete search results; only returned, validated records are described and search totals are not used.
Up to 100 returned search results ordered by commit date within the audit window; attribution trailers validated and duplicate SHAs removed across repositories. A recent convenience sample, not a random or exhaustive sample. Commit sample dates use the UTC committer timestamp, matching the search window. Excluded 0 commits with five or more distinct recognized agent/model credits in one message; broad credit lists are not used as evidence of a workflow.
Returned records dated Oct 9, 2026–Oct 11, 2026.
