Conciseness

The body is dense and assumes competence — no explanations of concepts Claude already knows, no padding — matching 'efficient; minor instances of over-explanation that could be trimmed'. It is not a 5 because several prohibition statements overlap ("Do not install, apply, recover, or upload local artifacts" vs. "do not claim installation or directory approval without verification" vs. repeating the no-apply constraint already in the description).

Actionability

Concrete tool names are given (open_workbench, inspect_stack, ui/workbench.html) and a specific review checklist ("exact IDs, catalog version, target, profile, proposed operations, artifact digests and cross-artifact mismatches"), but key execution details are missing — the "local preview CLI" is never named or invoked, and there is no example of opening the bundled HTML or composing evidence. This matches 'some concrete guidance but incomplete; missing key details' rather than 4's 'mostly executable guidance'.

Workflow Clarity

A clear primary path (open_workbench → review checklist), an explicit client fallback (inspect_stack → explain → open ui/workbench.html), and edge-case handling ("If no stack exists... ask... do not fabricate one"; "If an import fails or changes, clear stale results") provide most checkpoints. It is not 5 because the sequence is prose rather than ordered steps, and validation guidance (browser validation vs. Core inspection vs. semantic judgment) is stated as a distinction rather than an explicit validate-fix-retry loop; it is not 3 because failure recovery and grounding rules are explicitly present.

Progressive Disclosure

At ~25 lines with well-organized sections (When to Use, Workflow, Examples, Limitations) and no nested references, the structure is good and appropriately single-file. It is not 5 because the body points to bundled artifacts ("the bundled ui/workbench.html", "the catalog and supporting files are included") that are not present in the skill's bundle directories, leaving those references unverifiable rather than clearly navigable.

Specificity

The description enumerates several concrete review targets — "AAS stack manifests, preview plans and selection evidence" — within a named domain (Workbench), plus an explicit boundary ("without applying changes"). It stays below a 5 because coverage rests on a single verb ("Review") with minor gaps (no hint of the inspect_stack fallback or browser-vs-Core distinction).

Completeness

The 'what' is clear and concrete, but the 'when' is entirely absent — there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 2 because the 'what' is specific, not vague.

Trigger Term Quality

Relevant keywords are present ("review", "AAS", "stack", "manifests", "preview plans", "Workbench") but there are no common variations, synonyms, or natural trigger phrases a user would say. It matches the anchor 'some relevant keywords but missing common variations or synonyms' rather than 4, whose example shows broader natural-term coverage.

Distinctiveness Conflict Risk

The AAS/Workbench niche is clear and unlikely to trigger for unrelated skills, but generic terms ("review", "stack", "manifests") carry minor overlap risk with other review- or manifest-oriented skills, and the absence of explicit trigger guidance weakens distinctiveness. Not 5 because 'distinct triggers' are not explicitly stated.
