Totals across every corpus @ericodx 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 swift-mutation-testing corpus

ericodx/swift-mutation-testing: Measure and improve test effectiveness in Swift codebases using mutation testing

Example questions
Paste it into your AI agent. It clones the repo at the pinned commit and indexes it on your machine.
Search the GitHub repository ericodx/swift-mutation-testing with XERJ (https://hub.xerj.org/corpus/ericodx--swift-mutation-testing).
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/ericodx/swift-mutation-testing swift-mutation-testing && git -C swift-mutation-testing checkout 018e422545080e7b800708f18540b88762c4fb82
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./swift-mutation-testing --url http://127.0.0.1:9200 --prefix swift-mutation-testing --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
