Conciseness

The body avoids restating known concepts and defers detail to references, but abstract meta-framing like "Authoring is a thin projection and correction surface, not a separate modelling world" and "A target-shaped draft does not replace these distinctions while they remain load-bearing" is process philosophy that could be tightened into shorter plain directives. This is 'mostly efficient but includes some unnecessary explanation or could be tightened', not 4 because several such sentences add tokens without adding actionable instruction.

Actionability

There is some concrete guidance — "Activate the `elicitation` skill and read `references/gherkin-elicitation.md` before substantive questions", "Do not invent step-definition bindings", "Name unillustrated rules, ambiguous behavior, new or unchecked step phrases" — but key mechanics are deferred to an external `elicitation` skill and "core's" routing rule not in this bundle, and "Read `templates/workpiece.md`" points to a file absent from the bundle. Not a 4: these gaps leave an agent unable to execute parts of the instruction as written; not a 2 because per-stage direction is present and specific in intent.

Workflow Clarity

The lifecycle is clearly sequenced — orient, elicit or revise, maintain the workpiece, author or revise Gherkin, check and deliver — with an explicit runtime-branch selection up front and a "Check and deliver" stage that names what to report. Not a 5 because validation steps are named ("Apply the checks supported by the current capabilities") without any inline checkpoint or error-recovery detail; not a 3 because the sequence and its checkpoints (settle the workpiece before render-only handoff, deliver with gap accounting) are explicit.

Progressive Disclosure

The 52-line body is well-sectioned and points to two real one-level-deep references (`references/gherkin-elicitation.md`, `references/gherkin-authoring-and-checks.md`, both present), but it also instructs reading `templates/workpiece.md`, which does not exist in the bundle — the skill's own "Resource discipline" section makes that a broken navigation path. Not a 4: a dangling advertised resource is more than a minor organization gap; not a 2: most structure and references are appropriately placed and clearly signaled.

Specificity

The description lists several concrete actions — "Elicit or revise software behavior, maintain a recoverable behavior workpiece, and author or review honest Gherkin feature documents" — which maps to the 'several specific actions; minor gaps in coverage' anchor. It is not a 5 because supporting activities like checking/executing specs are only implicit, and not a 3 because more than 1-2 distinct actions are named.

Completeness

It explicitly answers both questions: what ("Elicit or revise software behavior, maintain a recoverable behavior workpiece, and author or review honest Gherkin feature documents") and when ("Use for a behavior-specification interview, Gherkin document, executable-specification draft, or review of any of them") with concrete trigger phrases. Not a 4 because the 'when' clause is explicit and enumerates specific triggering artifacts, satisfying the top anchor.

Trigger Term Quality

Natural terms a user would say appear — "Gherkin", "Gherkin document", "executable-specification draft" — giving good coverage, but common synonyms like "Cucumber", "BDD", "feature file", or ".feature" are missing. This fits the 'good keyword coverage; a few natural terms missing' anchor rather than 5 (no synonym/extension coverage) or 3 (more than a few natural terms present here).

Distinctiveness Conflict Risk

"Gherkin feature documents" and "behavior-specification interview" carve out a clear niche with distinct triggers unlikely to collide with other skills. Not a 4: the triggers are domain-specific terms rather than broad categories with minor overlap.
