Conciseness

The body is two lines: a provenance comment and one directive ("Load and follow the shared skill at ~/.agents/skills/pr-style/SKILL.md"). Nothing pads or over-explains; every token serves the redirect, matching anchor 5 ("lean and efficient; every token earns its place"). It is clearly above anchor 4, which still expects some trimmable over-explanation.

Actionability

The single directive is concrete and unambiguous (an exact action and path), so it clears anchor 2's "high-level hints". But it stops at a pointer: none of the actual formatting guidance (title format, body template, label mapping, assignment, draft policy) exists in the body or the bundle, and the referenced file "~/.agents/skills/pr-style/SKILL.md" is not present, so as shipped the skill delivers no executable value — below anchor 4's "concrete code or commands with minor gaps".

Workflow Clarity

The single action ("Load and follow the shared skill") is unambiguous, which under the simple-skill exception could score 5. However the one-step workflow dead-ends: the delegation target is missing from the bundle, and there is no checkpoint or fallback for that case (e.g., what to do if the file cannot be found), matching anchor 3's "sequence present but checkpoints missing or implicit".

Progressive Disclosure

The reference is one level deep and clearly signaled — the entire body is the pointer — but it points to an absolute home-directory path outside the skill bundle (no references/, scripts/, or assets/ directories exist), and that path does not resolve in this environment. The body also offers no overview of what the referenced material contains, fitting anchor 3 ("some structure but could be better organized") rather than anchor 4's "most content is appropriately placed".

Specificity

Enumerates five concrete coverage areas — "title, body template, label mapping, assignment, and draft policy" — plus an explicit purpose ("ensure consistent PR formatting"), which exceeds anchor 3's "1-2 concrete actions, but not comprehensive". It falls short of anchor 5 only because the items are topic nouns rather than named actions (no "formats", "applies", "maps" verbs), leaving the actual operations implied.

Completeness

Both parts are present: the "what" is the enumerated formatting reference (title, body template, label mapping, assignment, draft policy), and the "when" is explicit — "Invoked by pr/create and pr/update-desc commands" — so the missing-trigger cap of 3 does not apply. Not anchor 5 because the "when" is stated descriptively ("Invoked by...") rather than as concrete "Use when..." trigger phrases, and no natural-language invocation conditions are given.

Trigger Term Quality

Contains good natural keyword coverage: "PR formatting", "title", "body template", "label", "assignment", "draft", plus the concrete command triggers "pr/create" and "pr/update-desc". Anchor 5 (comprehensive synonyms/extensions) is not met because "pull request" is never spelled out and no natural-language trigger phrases (e.g., "when creating a PR") are given, but coverage is clearly above anchor 3's "missing common variations".

Distinctiveness Conflict Risk

Clear niche (PR formatting policy) with distinct triggers: the binding to the two named commands "pr/create" and "pr/update-desc" plus domain-specific terms ("label mapping", "draft policy") minimize conflict risk with neighboring git/PR skills, matching anchor 5's "clear niche with distinct triggers; minimal conflict risk". Anchor 4's "minor overlap risk with closely related skills" would require a less tightly scoped trigger than the explicit command binding.
