Why is NO one talking about Microsoft's open source Fast Context!!!

Microsoft has released FastContext-1.0, an open-source repository-exploration subagent designed for LLM coding tasks. This model separates the roles of repository exploration and task solving, utilizing parallel read-only tool calls to provide compact file paths and line ranges, leading to significant improvements in accuracy across benchmarks, including a 60.3% reduction in token usage for GPT-5.4 on SWE-QA. Practitioners can leverage FastContext to enhance the efficiency and performance of coding agents, potentially achieving better results with smaller models compared to larger alternatives.
