The prompt

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

Search the GitHub repository sgtlaugh/algovault with XERJ (https://hub.xerj.org/corpus/sgtlaugh--algovault).
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/sgtlaugh/algovault algovault && git -C algovault checkout 5e896b0fc78ce0ff2eb6f2478afe29664396da5f
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./algovault --url http://127.0.0.1:9200 --prefix algovault --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
