Weave: Merging based on language structure and not lines

Weave is a Git merge driver that resolves conflicts based on code structure rather than line overlaps, enabling clean merges when different developers edit separate functions in the same file. It successfully handled 31 out of 31 merge scenarios across 7 languages with zero regressions, significantly outperforming standard Git (48% success rate) and competing tools like Mergiraf (83%). The tool can be used standalone as a merge driver or integrated with multi-agent coordination and AI agents through an MCP server, supporting 38 programming languages and data formats.
