The prompt

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

Search the GitHub repository SpiliosDimakopoulos/fintwin with XERJ (https://hub.xerj.org/corpus/spiliosdimakopoulos--fintwin).
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/SpiliosDimakopoulos/fintwin fintwin && git -C fintwin checkout eb92ab60bd7650f6d87d3a7d9c722bbca07875de
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./fintwin --url http://127.0.0.1:9200 --prefix fintwin --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
