liuyuplus
liuyuplus's work was selected for the XERJ Corpus Hub, the open reference memory AI coding agents search before they write code. When an agent meets the same problem, it gets this implementation back as a worked example, with the author and the repository attached.
Totals across every corpus @liuyuplus 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 CodexBar corpus
steipete/CodexBar: Show usage stats for OpenAI Codex and Claude Code, without having to login
- Look up how CodexBar implements ai, codex, swift, with answers cited to file and line.
- Reuse a worked example: the commit “add Trae CN usage” (14 files · Swift, JavaScript).
- Answer from CodexBar's real Swift source instead of memory (AI, prompts and agents).
- Where does CodexBar handle “add Trae CN usage”?
- How does CodexBar implement ai?
- What does Tests do in CodexBar?
Search the GitHub repository steipete/CodexBar with XERJ (https://hub.xerj.org/corpus/steipete--codexbar). 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/steipete/CodexBar CodexBar && git -C CodexBar checkout 0703a0c015ffb08c0cbe45131f86d88a7bc85907 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./CodexBar --url http://127.0.0.1:9200 --prefix codexbar --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.

The corpus is the whole repository at the pinned commit, not only the files of the selected commit.
Not installable yet: this corpus is not in the hub registry until its licence review passes, so xerj corpus add and xerj ask cannot fetch it. It becomes installable when this card says live in the hub.
Sign in with GitHub or Hugging Face to see more: every selected commit in full (commit date, every folder, licence review state, pin) and the pack builds of each corpus.
