Ken C. Demanawa
Ken C. Demanawa'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 @kanutocd 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 whodunit corpus
kanutocd/whodunit: Lightweight creator/updater/deleter tracking for ActiveRecord models
- Look up how whodunit implements audit-trail, creator, deleter, with answers cited to file and line.
- Answer from whodunit's real source instead of memory (API design and specification).
- How does whodunit implement audit-trail?
Search the GitHub repository kanutocd/whodunit with XERJ (https://hub.xerj.org/corpus/kanutocd--whodunit). 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/kanutocd/whodunit whodunit && git -C whodunit checkout eafe75b1d8d21a6a3d1ab01e2443fc817d7abb66 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./whodunit --url http://127.0.0.1:9200 --prefix whodunit --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.
