spark
spark'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 @spark-328 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 openevals corpus
langchain-ai/openevals: Readymade evaluators for your LLM apps
- Reuse a worked example: the commit “preserve reordered records in same_elements JSON matching…” (4 files · TypeScript, Python).
- Answer from openevals's real TypeScript source instead of memory (AI, prompts and agents).
- What does js do in openevals?
Search the GitHub repository langchain-ai/openevals with XERJ (https://hub.xerj.org/corpus/langchain-ai--openevals). 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/langchain-ai/openevals openevals && git -C openevals checkout 9292ad6e9e523e14af32fcccf7f1fe22ccdad33e 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./openevals --url http://127.0.0.1:9200 --prefix openevals --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.
