-This model is [Qwen 3.5 2B](https://huggingface.co/Qwen/Qwen3.5-2B) fine-tuned to extract verbatim relevant lines from tool output given a task-specific query. It's trained on real software engineering tool output from SWE-bench (test logs, grep results, build errors, git diffs, stack traces, etc.), not generic text.
+Existing context pruning tools ([SWE-Pruner](https://github.com/Ayanami1314/swe-pruner), [Zilliz Semantic Highlight](https://huggingface.co/zilliz/semantic-highlight-bilingual-v1), [Provence](https://arxiv.org/abs/2501.16214)) are built for source code or document paragraphs. They don't handle the mixed, unstructured format of tool output (stack traces interleaved with passing tests, grep matches with context lines, build logs with timestamps).
