Odin is a browser-based debugging search engine that parses a repo and ranks the exact file (93%) and function (79.4%) to fix for a given bug, using Tree-sitter via WebAssembly and sub-1B local models via WebGPU, matching Claude 4.5 agent accuracy at a fraction of the cost on SWE-bench Lite.
The paper presents Libra, a self-evolving framework that introduces mutable catalogs into repositories to improve code localization for LLM agents, achieving logarithmic improvements and zero-shot transfer across different models and problem sets.
SWE-Explore introduces a benchmark for evaluating coding agents' repository exploration capabilities, requiring ranked lists of relevant code regions within line budgets. Experiments show agentic exploration outperforms traditional retrieval, and line-level coverage remains a key differentiator.
