Lowell Winston
Lowell Winston'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 @LowellWinston 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 polynx corpus
LowellWinston/polynx: pandas-style query/eval/assign for Polars: string expressions compiled to native Polars expressions. Eager + lazy, @var, UDFs, agent-ready
- Look up how polynx implements dataframe, eval, llm-tools, with answers cited to file and line.
- Reuse a worked example: the commit “Enhance engine: Add Polars plx namespace, optimize methods, add CI wo…” (7 files · Python).
- Answer from polynx's real Python source instead of memory (AI, prompts and agents).
- How does polynx implement dataframe?
- What does src/polynx do in polynx?
Search the GitHub repository LowellWinston/polynx with XERJ (https://hub.xerj.org/corpus/lowellwinston--polynx). 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/LowellWinston/polynx polynx && git -C polynx checkout 87e7131aafc7c33af007e7e8b8217b8f7167f33c 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./polynx --url http://127.0.0.1:9200 --prefix polynx --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.
