Example questions

What does R do in CAs?

The prompt

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

Search the GitHub repository ugroempi/CAs with XERJ (https://hub.xerj.org/corpus/ugroempi--cas).
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/ugroempi/CAs CAs && git -C CAs checkout 46faeac6a524f5da6f5a938e4329960d9258f48b
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./CAs --url http://127.0.0.1:9200 --prefix cas --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
