ForensicDbg's AI Crash Debugging Gauntlet

Why it matters

ForensicDbg, a Windows post-mortem debugging tool, ran a competitive evaluation of how well coding agents analyze crash dumps when given different debugging tools. Claude Code was pitted against a set of crash dumps using several setups: ForensicDbg's own MCP server, WinDbg accessed through svnscha's mcp-windbg, direct command-line use of CDB, LLDB, and no tool at all. The dumps mixed real-world and synthetic cases, ranging from simple crashes to complex heap corruption, with varying amounts of accompanying symbols and source code. Metrics covered analysis quality, actionability of suggested fixes, cost, and time. The no-tool baseline performed worst on every measure, which the authors present as evidence that dedicated debugging tools remain necessary for agents. A notable finding is that mcp-windbg improved comprehension and actionability over direct CDB use despite both relying on the same underlying debugger. ForensicDbg was the only entrant to reach the author's expected quality bar while staying mid-pack on cost and time. As a vendor-run benchmark, the framing favors the company's own product, but the methodology is described openly.
