This dataset contains the pipeline for constructing and analyzing a dataset of configuration artifacts for agentic AI coding tools (Claude Code, Gemini CLI, Codex CLI, Copilot CLI, Cursor) across GitHub repositories.The dataset is an extension of the dataset used for the following paper:M. Galster, S. Mohsenimofidi, J. Lulla, A. Muhammad Auwal, C. Treude and S. Baltes, “Configuring Agentic AI Coding Tools: An Exploratory Study (Supplementary Material)”. Zenodo, Mar. 20, 2026. doi: 10.5281/zenodo.18625980.This updated and extended version was accepted in the AIWare 2026 Datasets and Benchmarks track.Claude Code (Opus 4.6, high reasoning effort) was used to write and revise code and documentation for this pipeline. The research design and methodology are the work of the human authors.
