The prompt
Paste it into your AI agent. It clones bsikar/ra8-firmware at the pinned commit and indexes it on your machine.
Search the GitHub repository bsikar/ra8-firmware with XERJ (https://hub.xerj.org/corpus/bsikar--ra8-firmware). 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/bsikar/ra8-firmware ra8-firmware && git -C ra8-firmware checkout c258cd9326b2c3f4a64cf81c8211a3ff88dbfd6b 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./ra8-firmware --url http://127.0.0.1:9200 --prefix ra8-firmware --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.
