Astral Description Probe

The spec's description field "must be 1-1024 characters." It does not say what a character is. This skill's description is 869 Unicode code points, but 1319 UTF-16 code units and 2219 UTF-8 bytes, because most of it is emoji from the supplementary planes: each one is a single code point, two UTF-16 units, and four bytes. A platform that counts code points sees a compliant description; one that counts UTF-16 units (JavaScript's .length) or bytes sees an oversize one.

The description carries an ASCII head marker near its start and an ASCII tail marker as its final characters (bird-mineral phrases; the head marker's bird is MAGPIE and the tail marker's bird is LINNET). A listing that shows the head but not the tail reveals truncation. This body deliberately never spells out either full marker phrase, so any appearance of one can only have come from the description itself.

Pair this skill with probe-long-description (ASCII, over the limit in every unit) and probe-multibyte-description (under the limit in code points and UTF-16 units, over it in bytes) to tell the counting units apart.
