Conciseness

The body is ~2,200 lines / ~158KB, with substantial padding: the telemetry command block and its "--audience is the site audience captured in Phase 1... Do not include site name, URL..." caveat are repeated near-verbatim 5+ times, "Do not emit template_import_failure because no import was attempted; template_used was already emitted" appears 7+ times, and the ~120-line PLAN_LABELS dictionary is fully inlined. This matches anchor 2 ("noticeably verbose; several unnecessary explanations or padded sections") — it is beyond anchor 3's "some unnecessary explanation" in scale, though not anchor 1 since it rarely explains concepts Claude already knows.

Actionability

Fully executable throughout: exact bash invocations with every flag (e.g., `node "${PLUGIN_ROOT}/scripts/fetch-template-variant.js" --sha ... --variant ...`), concrete JSON file shapes for scaffold-status.json, exit-code semantics ("Treat exit code 2 as blocking", "exits 1 when blocking rendered findings exist; parse stdout on that expected path"), per-framework marker-syntax tables, and exact AskUserQuestion tables. This matches anchor 5 ("fully executable; copy-paste ready... specific examples cover the common cases"); anchor 4 would imply minor executable gaps that are not evident.

Workflow Clarity

The phase sequence (1 → 8) is explicit with abundant validation checkpoints, gates, and feedback loops ("rerun the command until it passes", critique rounds capped at three with a user gate, re-run axe after fixes), matching anchor 5's substance. However, the Phase 1.5 outline is genuinely hard to follow: two different top-level steps are both numbered "8" ("8. For the template path only" and "8. For the from-scratch path only") and nested sub-lists restart numbering at inconsistent depths, which is a sequencing defect anchor 5's "clear sequence" does not permit — hence 4 rather than 5, while clearly above anchor 3's "checkpoints missing or implicit" since checkpoints are explicit everywhere.

Progressive Disclosure

References are clearly signaled at point of use (design-aesthetics.md, page-blueprints.md, design-critique.md, non-spa-site.md), giving real structure. But scored against the actual bundle: most referenced files (page-blueprints.md, design-critique.md, bidirectional-design.md, rendered-bidirectional-verification.md, approval-gates.md, and nearly all ${PLUGIN_ROOT}/scripts) are absent, the one present reference (design-aesthetics.md) is a 5-line redirect stub chaining two directories up, and large content that belongs in references (PLAN_LABELS dictionary, Live Preview Status Protocol) is inlined. This sits between anchor 2 (content clearly belonging in separate files inlined) and anchor 3 (some structure, references present but organization could improve), slightly above the midpoint of that pair — 3.

Specificity

Lists multiple concrete actions with comprehensive coverage of the domain: "Creates a new Power Pages site from an SPA or non-SPA template, or scaffolds an SPA from scratch using React, Angular, Vue, or Astro" plus "Guides requirements discovery, template selection, provisioning, design, validation, and deployment" — both creation modes, all four frameworks, and the full lifecycle. It fits the 5 anchor ("multiple specific concrete actions; comprehensive coverage") better than 4, which implies notable coverage gaps; none are apparent for this skill's scope.

Completeness

Explicitly answers both questions: the "what" is concrete site creation from templates or from scratch, and the "when" is a literal "Use when the user wants to create, build, use a template for, or scaffold a new Power Pages website or portal" with concrete trigger phrases. This matches the 5 anchor exactly; 4 would require the "when" to be less explicit, which it is not.

Trigger Term Quality

Good natural-verb coverage in "Use when the user wants to create, build, use a template for, or scaffold a new Power Pages website or portal", with both "website" and "portal" as nouns. A few natural phrasings users might say are missing (e.g., "set up", "make", "launch a new site"), so it sits between the 4 anchor ("good keyword coverage; a few natural terms missing") and 5 (comprehensive synonyms), closer to 4.

Distinctiveness Conflict Risk

"Power Pages" names a specific product and the triggers are creation-specific ("create... or scaffold a new Power Pages website or portal"), a clear niche distinct from sibling skills like deploy, edit, or activate. Risk is limited to closely related same-plugin skills, matching the 5 anchor ("clear niche with distinct triggers; minimal conflict risk").
