Conciseness

The body is lean and assumes competence throughout: "The advisor has zero context. Make it self-contained", "Relevant files by path (don't paste — let the agent read)". No concept is explained that Claude doesn't already know; every line is either an instruction, a decision rule, or literal text to use. Even the opening ("Single agent. Reads the situation. Gives a judgment.") is functional framing that sets the advisory-not-delegation contract. This matches anchor 5 (lean, every token earns its place) rather than anchor 4, which would require identifiable over-explanation to trim — none is present.

Actionability

Guidance is highly concrete: named tool calls ("Call `list_profiles`", "Materialize the selected profile into `create_agent`"), an explicit title format ("`[Advisor] <topic>`"), a briefing checklist, and two copy-paste-ready text blocks (the no-edits suffix and the forwarded-skill invocation line). It falls just short of anchor 5 because the actual agent-creation mechanics and the "provider discovery fallback" are delegated wholesale to the external paseo skill, leaving minor execution gaps a reader must resolve elsewhere — squarely anchor 4 ('mostly executable guidance; concrete code or commands with minor gaps').

Workflow Clarity

The sequence is coherent and well-gated: read paseo + list_profiles first, an explicit gate ("Do not create the advisor until you have read the configured profiles"), profile selection rules, briefing construction, forwarded-skill handling, then launch-wait-read-synthesize. It is not anchor 5 because there are no validation or recovery checkpoints for the failure modes (advisor returns nothing useful, no profile fits beyond the fallback mention, response contradicts the current state) — anchor 4 ('clear sequence with most checkpoints present; minor validation gaps') is the best fit. The destructive/batch cap does not apply since the skill enforces a no-edits contract.

Progressive Disclosure

The bundle contains no references/, scripts/, or assets/ directories — the skill is a single appropriately sized file with well-organized, clearly titled sections (Prerequisites, Picking the advisor, The briefing, Forwarded skills, Launch and synthesize, Persistent advisor). Its one external dependency (the paseo skill) is explicitly signaled at the top rather than buried, and nothing that belongs in a separate file is inlined. Per the rubric's guidance for simple single-file skills with well-organized sections, this matches anchor 5.

Specificity

The description names the domain ("single agent as an advisor") and one or two concrete actions ("Spin up a single agent", "second opinion on the current task"), but does not enumerate what the skill actually does at execution time (briefing construction, forwarded skills, synthesis, persistent advisor). It matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive') rather than anchor 4, which requires 'several specific actions' listed.

Completeness

Both halves are explicit: what — "Spin up a single agent as an advisor — second opinion on the current task"; when — "Use when the user says 'advisor', 'second opinion', 'what does X think', or wants an outside take without delegating the work itself." This mirrors the anchor-5 good example's what-plus-concrete-trigger-phrase structure; it is not the anchor-4 case since the when-clause is fully explicit, not merely present.

Trigger Term Quality

It quotes the natural phrases a user would actually say: "advisor", "second opinion", "what does X think", plus the synonym "an outside take". File extensions are inapplicable to this non-file domain, so coverage of natural terms and their synonyms is comprehensive, matching anchor 5.

Distinctiveness Conflict Risk

The niche is narrow (advisory second opinion) with distinct trigger terms, and the qualifier "without delegating the work itself" explicitly separates it from generic delegation/subagent skills. Conflict risk is minimal, matching anchor 5; anchor 4 would require some overlap concern with a closely related skill, which is not the case here.
