The body is lean with no concept-explanation padding and assumes Claude's competence; each section (scope, constraints, triggers, workflow, reference) serves a distinct purpose. It avoids a 2 only because the mild "When to use" duplication of the description's triggers does not rise to the verbosity/padding the 2 anchor describes.

"Read references/034-architecture-design-exploration.md, the sanitized issue or requirement summary, relevant code, existing ADRs, diagrams, and constraints" and "compare complexity, maintainability, performance, security, testability, migration impact, operational cost" name exact artifacts and dimensions. As an instruction-only skill the absence of code is not penalized; it is not a 2 because the guidance is complete and concrete rather than vague or pseudocode-like.

Five numbered steps carry explicit checkpoints — "Resolve blocking ambiguity with focused questions before comparing solutions," the TRUST GATE, and "Obtain user approval before treating a direction as selected" — with the Constraints block acting as a MUST/MUST NOT checklist. It is not a 2 because checkpoints are explicit rather than implicit, and the operations are not destructive/batch so the workflow_clarity cap does not apply.

The body is an overview pointing to a single, clearly signaled one-level-deep reference — "[references/034-architecture-design-exploration.md](references/034-architecture-design-exploration.md)" — and that file exists on disk. It is not a 2 because the reference is well-signaled and shallow rather than inline or nested.

"inspects repository context, clarifies material ambiguity, compares feasible approaches and trade-offs, recommends a direction, obtains approval, and identifies ADR candidates" lists multiple specific concrete actions. It is not a 2 because the action list is comprehensive rather than naming only a domain and partial actions.

It answers "what" with an explicit action list and "when" with both a "Use when a sanitized issue summary... needs technical design exploration" clause and a "This should trigger for requests such as..." clause. It is not a 2 because the trigger guidance is explicit rather than implied.

"Explore a design; Compare implementation approaches; Recommend an architecture direction; Clarify technical options before planning" are natural phrases a user would actually say. It is not a 2 because several common variations are covered rather than a single keyword.

The niche — sanitized-summary-driven architecture/ADR design exploration — is specific with distinct triggers unlikely to overlap other skills. It is not a 2 because the triggers point to a clear, narrow domain rather than a broad "works with documents" scope.
