zax
zax'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 @zaxchou 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 fermata corpus
zaxchou/fermata: zaxchou/fermata (Python)
- Look up how fermata implements audio, bluetooth, keepalive, with answers cited to file and line.
- Reuse a worked example: the commit “Review pass: cut the CPU cost 10x, fix the state that drifts, add a C…” (9 files · Python).
- Answer from fermata's real Python source instead of memory (Web and frontend platform).
- How does fermata implement audio?
- What does app/core do in fermata?
Search the GitHub repository zaxchou/fermata with XERJ (https://hub.xerj.org/corpus/zaxchou--fermata). 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/zaxchou/fermata fermata && git -C fermata checkout cfa5a4e4905a6ee23cd61af0c49b4b9225f0cea9 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./fermata --url http://127.0.0.1:9200 --prefix fermata --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.
