JSON Array Append Position Token Tool Resolve a supplied final array token for an insertion context; - is special only for add.
JSON Array Hole Vs Null Label Tool Distinguish an out-of-range JSON array index from an explicit null or present value. JSON arrays cannot encode JavaScript sparse holes.

JSON Pretty Printer Format JSON text with consistent indentation and a trailing newline.

JSON: JSON Scalar Type Tag Tool Tag one parsed JSON scalar, explicitly distinguishing null and rejecting arrays/objects rather than pretending they are scalars.
JSON: JSON Schema Nullable Enum Flag Tool Inspect explicit null membership of one nonempty JSON Schema enum value array, not overall schema nullability under other keywords.
JSON: JSON Schema Required Member Flag Tool Check one member against an explicitly supplied JSON Schema required-name array, rejecting duplicate declarations and not evaluating an entire schema.
