Sabit Zahin
Sabit Zahin'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 @sgtlaugh 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 algovault corpus
sgtlaugh/algovault: Algorithms and templates for competitive programming
- Look up how algovault implements competitive-programming, data-structures, codeforces, with answers cited to file and line.
- Reuse a worked example: the commit “add ntt practice solutions” (3 files · C++).
- Answer from algovault's real C++ source instead of memory (API design and specification).
- Where does algovault handle “add ntt practice solutions”?
- How does algovault implement competitive-programming?
- What does practice do in algovault?
Search the GitHub repository sgtlaugh/algovault with XERJ (https://hub.xerj.org/corpus/sgtlaugh--algovault). 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/sgtlaugh/algovault algovault && git -C algovault checkout 5e896b0fc78ce0ff2eb6f2478afe29664396da5f 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./algovault --url http://127.0.0.1:9200 --prefix algovault --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.
