Daniel Beltrán
Daniel Beltrán'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 @d-beltran 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 MDDB-workflow corpus
mmb-irb/MDDB-workflow: mmb-irb/MDDB-workflow (Python)
- Look up how MDDB-workflow implements molecular-dynamics, with answers cited to file and line.
- Reuse a worked example: the commit “improved pbc box testing” (6 files · Python).
- Answer from MDDB-workflow's real Python source instead of memory (API design and specification).
- Where does MDDB-workflow handle “improved pbc box testing”?
- How does MDDB-workflow implement molecular-dynamics?
- What does mddb_workflow do in MDDB-workflow?
Search the GitHub repository mmb-irb/MDDB-workflow with XERJ (https://hub.xerj.org/corpus/mmb-irb--mddb-workflow). 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/mmb-irb/MDDB-workflow MDDB-workflow && git -C MDDB-workflow checkout a1e6d4a7d741f84f3ebe9082962f7a95e5e32502 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./MDDB-workflow --url http://127.0.0.1:9200 --prefix mddb-workflow --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.
