Resilient Write: A Six-Layer Durable Write Surface for LLM Coding Agents

arXiv:2604.10842v1 Announce Type: cross Abstract: LLM-powered coding agents increasingly rely on tool-use protocols such as the Model Context Protocol~(MCP) to read and write files on a developer's workstation. When a write fails -- due to content filters, truncation, or an interrupted session -- the agent typically receives no structured signal, loses the draft, and wastes tokens retrying blindly. We present \textbf{Resilient Write}, an MCP server that interposes a six-layer durable write surfa
