The prompt
Paste it into your AI agent. It clones fcpp/fcpp at the pinned commit and indexes it on your machine.
Search the GitHub repository fcpp/fcpp with XERJ (https://hub.xerj.org/corpus/fcpp--fcpp). 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/fcpp/fcpp fcpp && git -C fcpp checkout e89b1ccb3f008b1dff072f2e017b52ce96076975 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./fcpp --url http://127.0.0.1:9200 --prefix fcpp --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.
