The prompt

Paste it into your AI agent. It clones kanutocd/cdc-core at the pinned commit and indexes it on your machine.

Search the GitHub repository kanutocd/cdc-core with XERJ (https://hub.xerj.org/corpus/kanutocd--cdc-core).
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/kanutocd/cdc-core cdc-core && git -C cdc-core checkout 046dbdc35348b32e208b402ebefc60f57cf6393a
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./cdc-core --url http://127.0.0.1:9200 --prefix cdc-core --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
