Auto-mode classifier logs no longer include raw prompt or error text, only lengths
Debug and telemetry logging for the auto-mode classifier (the internal system that classifies actions Claude is about to take) no longer includes the actual text being classified. Previously the log for "new action being classified" could include up to 500 characters of the action's text; it now logs only the tool name, the length of the action text, and the tool-use ID. Similarly, when input to the classifier is malformed, the log used to include the actual error message text; it now logs only the character count of that error.
This reduces the chance of sensitive or raw prompt content ending up in logs, while still preserving enough information (lengths, identifiers) for debugging.
Nothing has been read yet about whether the `tengu_auto_mode_malformed_tool_input` gate is on or off for this site's account.
