Length-unit probe math-forty. Benchmark skill whose name is a name of lowercase mathematical bold letters from the astral plane (40 code points, 74 UTF-16 units, 142 UTF-8 bytes), under the cap in code points but over it in UTF-16 units and bytes. Use when asked to probe name length units.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Astral Name Probe This skill's name is the fixture: the directory name and the frontmatter name match, and the only rule in play is how long the name is when counted in a particular unit. The spec says a name "must be 1-64 characters" and "may only contain unicode lowercase alphanumeric characters (`a-z`, `0-9`) and hyphens", which leaves both the counting unit and the character set open to interpretation. Read together with its siblings and with the 72-character ASCII fixture from `invalid-name-tolerance`, this skill's presence or absence from the catalog shows which unit the platform counts, or whether it rejects non-ASCII names regardless of length. This body never repeats the description's marker phrase, so the phrase can only have come from the catalog listing. ## Instructions When activated, report: "Astral Name Probe activated." and state your skill's name exactly as your catalog lists it.

How to install
mdr add agent-ecosystem/agent-skill-implementation/probe-๐๐๐๐๐๐๐ ๐ก๐ข๐ฃ๐ค๐ฅ๐ฆ๐ง๐จ๐ฉ๐ช๐ซ๐ฌ๐ญ๐ฎ๐ฏ๐ฐ๐ฑ๐ฒ๐ณ๐๐๐๐๐๐๐ ๐ก@sha256:98eb13fbbb513fbfThe line at the top of this page pins the label git:20260926.cb3708f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
