UnverifiedThe model itself never runs code; it only writes out requests to call tools, and it is external code that actually executes the tools64% similarUnverifiedEverything Claude does to a user's account is done through Tools; Claude will not bypass tools to directly manipulate a user's account, files or system.62% similarUnverifiedIn tool calling, the model itself does not execute code but is only responsible for deciding which tool to call, while actual execution authority remains in the host program controlled by the developer.59% similarUnverifiedThe so-called backdoor risk does not exist because only Claude Code's tools and client are used, not its account or model.56% similarUnverifiedThere is no model in trainproof's pipeline; every determination is a deterministic rule, and identical inputs always produce identical outputs.55% similar
