Andrey Butcitcyn
Andrey Butcitcyn's work was selected for the XERJ Corpus Hub, the open reference memory AI coding agents search before they write code. When an agent meets the same problem, it gets this implementation back as a worked example, with the author and the repository attached.
Totals across every corpus @btctcn appears in; a commit selected for two corpora counts once. Files and lines count the selected commits; each corpus indexes the whole repository at its pinned commit.
What an agent can do with the swift-isolation-map corpus
btctcn/swift-isolation-map: Static actor isolation and data-race analysis for Swift projects
- Look up how swift-isolation-map implements ci, cli, data-race, with answers cited to file and line.
- Reuse a worked example: the commit “Fix SwiftPM index-store and compiler-args resolution under swift buil…” (5 files · Swift).
- Answer from swift-isolation-map's real Swift source instead of memory (API design and specification).
- How does swift-isolation-map implement ci?
- What does Sources do in swift-isolation-map?
