UnverifiedEarly JWT specifications allowed setting the signing algorithm to none, and some implementations would directly accept unsigned tokens.72% similarUnverifiedProviders do not send the user's JSON to the model as-is; instead they rewrite it into an internal format and add their own instructions, so the real token numbers will differ and vary by provider; it is recommended to verify by comparing the difference between with-tools and without-tools via the usage.prompt_tokens field.71% similarUnverifiedEven when using structured output interfaces, occasional format drift or missing fields from the model still occur, and production environments typically require adding JSON validation and exception fallback mechanisms.70% similarUnverifiedSystem prompts alone cannot guarantee that every output meets standard practices; connecting structured JSON asset files is the key to producing consistently standardized outputs70% similarUnverifiedPreToolUse and PermissionRequest hooks are no longer skipped when matching fails or tool input cannot be serialized to JSON; instead, the call is directly blocked.69% similar
