| 🛠️ | patchwork open-sourcing soon |
An agent that localises and fixes bugs in real Python repos, or escalates when it shouldn't try. Ships with a contamination-safe benchmark of 111 post-2024 GitHub issues, a BM25 baseline, and JSONL traces of every token and dollar spent.Python LLMs uv pytest GitHub Actions |
| 🗺️ | Barcelona POI recommender simulation | An agent-based simulation of 3,000 tourists that compares popularity, interest-based and sustainability-aware recommenders on accuracy and overcrowding. The sustainability-aware recommender cut overcrowding events from 99 to 11 compared with the interest-based one.Python Mesa NumPy Flask React Leaflet |
| 📦 | mini-pnpm | pnpm rebuilt from scratch: a content-addressable global store, a hard-linked virtual store, incremental lockfile resolution that only touches the changed subgraph, and tarball integrity verification.TypeScript Node.js npm registry API |
