New gate tengu_tidy_fern can add an extra value into how user messages are built
A new internal flag, tengu_tidy_fern, controls whether an extra value is computed and passed along when Claude Code builds a user message for tool use. Previously this value was always left empty; now, when the flag is on, it is computed via a new function and included instead.
The finding doesn't say what this extra value is used for, so it's unclear what practical difference this makes for a user.
