The prompt
Paste it into your AI agent. It clones ATOMSLab/LeanSMILES at the pinned commit and indexes it on your machine.
Search the GitHub repository ATOMSLab/LeanSMILES with XERJ (https://hub.xerj.org/corpus/atomslab--leansmiles). 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/ATOMSLab/LeanSMILES LeanSMILES && git -C LeanSMILES checkout c313442acbfa56dc653fb5138d64b1241d0066b2 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./LeanSMILES --url http://127.0.0.1:9200 --prefix leansmiles --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.
