Summary
MCP's operational sins, Sloth and Wrath, cause systems to fail obscurely or amplify failures under stress. Combat Sloth by implementing structured ToolError classes with codes like 'invalid_input' and 'not_found', enforcing stdio hygiene (log to stderr), and surfacing precise error contracts via functions like toMcpErrorResult. This ensures truthful failure reporting and sane recovery in live model-facing interfaces.
