MathsionYang
MathsionYang'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 @MathsionYang 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 CodexChat- corpus
MathsionYang/CodexChat-: OpenAI Codex VS Code 扩展的本地会话伴生管理器。它读取本机 .codex 数据目录，按会话中的 cwd 将历史会话归入项目文件夹。
- Reuse a worked example: the commit “add persistent pins and confirmed deletion in 0.1.9” (17 files · TypeScript, JavaScript).
- Answer from CodexChat-'s real TypeScript source instead of memory (AI, prompts and agents).
- Where does CodexChat- handle “add persistent pins and confirmed deletion in 0.1.9”?
- What does test do in CodexChat-?

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.
