Matteo Croce
Matteo Croce'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 @teknoraver 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 jpegoptim corpus
tjko/jpegoptim: jpegoptim - utility to optimize/compress JPEG files
- Look up how jpegoptim implements image-optimization, libjpeg, jpeg-encoder, with answers cited to file and line.
- Reuse a worked example: the commit “Add --strip-ai option to remove AI generation metadata” (6 files · C, Python).
- Answer from jpegoptim's real C source instead of memory (API design and specification).
- Where does jpegoptim handle “Add --strip-ai option to remove AI generation metadata”?
- How does jpegoptim implement image-optimization?
- What does test do in jpegoptim?
Search the GitHub repository tjko/jpegoptim with XERJ (https://hub.xerj.org/corpus/tjko--jpegoptim). 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/tjko/jpegoptim jpegoptim && git -C jpegoptim checkout 4310d5497bf957b425ace94731dd3940de4da3f4 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./jpegoptim --url http://127.0.0.1:9200 --prefix jpegoptim --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.
