Thorsten Foltz
Thorsten Foltz'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 @thorstenfoltz 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 octa corpus
thorstenfoltz/octa: Fast native desktop app for exploring 20+ data formats like Parquet, DuckDB, CSV, Excel, Arrow, GeoJSON, Jupyter and more, plus connections
- Look up how octa implements csv, editor, excel, with answers cited to file and line.
- Reuse a worked example: the commit “⚡ feat(data): scale data workflows” (50 files · Rust, shell).
- Answer from octa's real Rust source instead of memory (AI, prompts and agents).
- Where does octa handle “⚡ feat(data): scale data workflows”?
- How does octa implement csv?
- What does src/app do in octa?
Search the GitHub repository thorstenfoltz/octa with XERJ (https://hub.xerj.org/corpus/thorstenfoltz--octa). 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/thorstenfoltz/octa octa && git -C octa checkout 3e3273b004c5c428f85a53720bf43b5d5101d6d9 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./octa --url http://127.0.0.1:9200 --prefix octa --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.
