Example questions

Where does citibike handle “date range select”?

The prompt

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

Search the GitHub repository zack/citibike with XERJ (https://hub.xerj.org/corpus/zack--citibike).
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/zack/citibike citibike && git -C citibike checkout cf2c4a18a09d5cc706353d29ed70b9bed5b1929d
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./citibike --url http://127.0.0.1:9200 --prefix citibike --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
Licence: AGPL-3.0. Read it for the approach only, do not copy code.
