Hermann Rolfes
Hermann Rolfes'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 @kungfooman 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 RuntimeTypeInspector.js corpus
kungfooman/RuntimeTypeInspector.js: Checking JSDoc types at runtime for high-quality types - Trust is good, control is better
- Reuse a worked example: the commit “Map checks: scan fast path plus doubling rescan windows” (40 files · JavaScript).
- Answer from RuntimeTypeInspector.js's real JavaScript source instead of memory (API design and specification).
- Where does RuntimeTypeInspector.js handle “Map checks: scan fast path plus doubling rescan windows”?
- What does src-runtime do in RuntimeTypeInspector.js?
Search the GitHub repository kungfooman/RuntimeTypeInspector.js with XERJ (https://hub.xerj.org/corpus/kungfooman--runtimetypeinspector-js). Run these in a shell, in order, and check each result before the next: 1. xerj --help (success: it prints usage). If xerj is missing: curl -fsSL https://xerj.org/get | sh 2. git clone https://github.com/kungfooman/RuntimeTypeInspector.js RuntimeTypeInspector.js && git -C RuntimeTypeInspector.js checkout b5b5ccb4d732d673a576a4be24ecd29fbdf584d0 3.

The corpus is the whole repository at the pinned commit, not only the files of the selected commit.
Not installable yet: this corpus is not in the hub registry until its licence review passes, so xerj corpus add and xerj ask cannot fetch it. It becomes installable when this card says live in the hub.
