Corpus Hub contributor since 2026-10-20

Luke Roy'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 @Luke-Roy-IBM 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 CodeEngine corpus

IBM/CodeEngine: Samples for using Code Engine

Look up how CodeEngine implements ibm-cloud, code-engine, ibm-cloud-code-engine, with answers cited to file and line.
Reuse a worked example: the commit “Clef on Fleets” (8 files · Python).
Answer from CodeEngine's real Python source instead of memory (Operations and SRE).

Example questions

Where does CodeEngine handle “Clef on Fleets”?
How does CodeEngine implement ibm-cloud?
What does serverless-fleets do in CodeEngine?

Paste it into your AI agent. It clones the repo at the pinned commit and indexes it on your machine.

Search the GitHub repository IBM/CodeEngine with XERJ (https://hub.xerj.org/corpus/ibm--codeengine).
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/IBM/CodeEngine CodeEngine && git -C CodeEngine checkout f4ccdfb9264ce3e1869b20723ae0b5644b345e43
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./CodeEngine --url http://127.0.0.1:9200 --prefix codeengine --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. Query syntax: https://xerj.org/llms.txt

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.
