Look up how auctions-server-1 implements auctions, design-patterns, distributed-systems, with answers cited to file and line.
Reuse a worked example: the commit “Upgrade Spring stack and harden auctions” (9 files · Java).
Answer from auctions-server-1's real Java source instead of memory (API design and specification).

Example questions

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

Search the GitHub repository rcarball/auctions-server-1 with XERJ (https://hub.xerj.org/corpus/rcarball--auctions-server-1).
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/rcarball/auctions-server-1 auctions-server-1 && git -C auctions-server-1 checkout d17a8e39da470a86382a25ed007a8f5108b5b994
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./auctions-server-1 --url http://127.0.0.1:9200 --prefix auctions-server-1 --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
