Conciseness

The body is two functional lines ("Load and follow the shared skill at `~/.agents/skills/grill-me/SKILL.md`.") plus a generation comment — zero padding and no explanation of anything Claude already knows. This matches anchor 5 ("Lean and efficient; assumes Claude's competence; every token earns its place").

Actionability

The single directive is fully specified with a concrete path, so it is executable as written; but it delegates all actual guidance to an external file outside the skill bundle and offers no fallback if that file is absent. This fits anchor 4 ("Mostly executable guidance... minor gaps") better than anchor 5, which expects the guidance itself to cover the common cases.

Workflow Clarity

As a single-action skill the instruction ("Load and follow") is unambiguous, matching the simple-skill exception, but there is no checkpoint for the failure mode where the referenced shared skill does not exist. This places it at anchor 4 ("Clear sequence with most checkpoints present; minor validation gaps") rather than 5; no destructive/batch cap applies.

Progressive Disclosure

The reference is clearly signaled and only one level deep, but the body contains no overview of what the target skill covers, and the pointer lives outside the skill bundle (`~/.agents/...`), so navigation cannot be verified from the skill itself. This falls between anchors 3 and 4; the absent overview and unverifiable external target tip it to 3.

Specificity

Names the domain and a distinctive mode ("A relentless interview to sharpen a plan or design") but describes only one action with no enumeration of what the interview actually does. It sits at anchor 3 ("Names domain and 1-2 concrete actions, but not comprehensive") — more specific than the generic anchor-2 example, but well short of anchor 4's several specific actions.

Completeness

The description clearly answers "what" ("A relentless interview to sharpen a plan or design") but "when" is entirely absent — there is no "Use when..." clause or equivalent. Per the judging guidelines, a missing 'Use when' clause caps completeness at 3, which is exactly where this lands.

Trigger Term Quality

"interview", "plan", and "design" are relevant keywords, but common natural variations users would say ("grill me", "challenge my plan", "stress-test my design", "poke holes") are missing. This matches anchor 3 ("Some relevant keywords but missing common variations or synonyms") rather than anchor 4's good coverage.

Distinctiveness Conflict Risk

"relentless interview to sharpen a plan or design" carves a recognizable niche (adversarial plan critique), but it could still overlap with plan-review or design-review skills. This matches anchor 3 ("Somewhat specific but could still overlap with similar skills") — not anchor 4, which requires minimal overlap with only closely related skills.
