Filip Polak
Filip Polak'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 @rabbitxone 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 annotator corpus
rabbitxone/annotator: Browser extension for creating annotations 😉
- Reuse a worked example: the commit “Markdown help, ⌘/Ctrl+click links, lists and escapes in the note editor” (21 files · JavaScript).
- Answer from annotator's real JavaScript source instead of memory (Web and frontend platform).
- What does src/shared do in annotator?
Search the GitHub repository rabbitxone/annotator with XERJ (https://hub.xerj.org/corpus/rabbitxone--annotator). 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/rabbitxone/annotator annotator && git -C annotator checkout 00ef67066c3d69211ccb2a0649fec5d91fb8c1a6 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./annotator --url http://127.0.0.1:9200 --prefix annotator --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.
