The prompt

Paste it into your AI agent. It clones ishay60/mcpolyglot at the pinned commit and indexes it on your machine.

Search the GitHub repository ishay60/mcpolyglot with XERJ (https://hub.xerj.org/corpus/ishay60--mcpolyglot).
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/ishay60/mcpolyglot mcpolyglot && git -C mcpolyglot checkout 03059f1e737fa3e10653f3933420af3b7c8ba96a
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./mcpolyglot --url http://127.0.0.1:9200 --prefix mcpolyglot --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
