Jakub
Jakub'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 @kubashh 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 VirginEngine corpus
kubashh/VirginEngine: Simple JS game engine for 2D web games
- Look up how VirginEngine implements virgin-engine, game-engine, game-engine-2d, with answers cited to file and line.
- Reuse a worked example: the commit “More explicit types in core classess” (17 files · TypeScript).
- Answer from VirginEngine's real TypeScript source instead of memory (Web and frontend platform).
- Where does VirginEngine handle “More explicit types in core classess”?
- How does VirginEngine implement virgin-engine?
- What does core/src do in VirginEngine?
Search the GitHub repository kubashh/VirginEngine with XERJ (https://hub.xerj.org/corpus/kubashh--virginengine). 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/kubashh/VirginEngine VirginEngine && git -C VirginEngine checkout 2854087a590337931cf996b45a9585ce02abb5d8 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./VirginEngine --url http://127.0.0.1:9200 --prefix virginengine --progress plain 5. xerj autoindex map --url http://127.0.0.1:9200 Then answer my question from the indexed files and cite the ax_path of every hit.

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.
Sign in with GitHub or Hugging Face to see more: every selected commit in full (commit date, every folder, licence review state, pin) and the pack builds of each corpus.
