Totals across every corpus @btctcn appears in; a commit selected for two corpora counts once. Files and lines count the selected commits; each corpus indexes the whole repository at its pinned commit.

What an agent can do with the swift-isolation-map corpus

btctcn/swift-isolation-map: Static actor isolation and data-race analysis for Swift projects

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 btctcn/swift-isolation-map with XERJ (https://hub.xerj.org/corpus/btctcn--swift-isolation-map).
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/btctcn/swift-isolation-map swift-isolation-map && git -C swift-isolation-map checkout 59f0830b895e3788a76c9a93bae0f80361526b1a
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./swift-isolation-map --url http://127.0.0.1:9200 --prefix swift-isolation-map --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
