Conciseness

The body is lean (~45 lines) with no explanations of concepts Claude already knows and no padding. It falls short of anchor 5 only because the opening sentence ("Duplicate titles prevent Google from determining which page is the authoritative result...") duplicates the reference's "Why It Matters" section nearly verbatim, and the Explain section restates well-known SEO effects.

Actionability

The Check section gives a concrete executable procedure ("Crawl all pages and extract <title> tag content. Group pages by identical title text and flag duplicates") and the Fix section provides specific per-page-type patterns with a concrete template ("[Specific Topic] – [Site Name]"). Not anchor 5 because the body itself contains no copy-paste-ready command or code — that lives in the reference — but the guidance is specific enough to execute, well above anchor 3's pseudocode level.

Workflow Clarity

The Check → Fix → Explain → Code Review sequence is clearly ordered, but validation in the body is only implicit ("describe how to verify the final page output") rather than an explicit checkpoint. Crawling all site pages is a batch operation, and per the judging guidelines a batch workflow without explicit validation steps in the body caps workflow clarity at 3 — the reference's Verification section prevents a lower score.

Progressive Disclosure

The body is under 50 lines with well-organized sections and a single clearly signaled, one-level-deep reference ("see references/rule.md") that actually exists and appropriately carries the code examples and framework-specific guidance. This matches anchor 5's clear overview with well-signaled shallow references and easy navigation.

Specificity

The description names the domain ("HTML pages", "site crawl report", "search results") but contains no concrete capability actions — no verbs describing what the skill does (check, audit, fix titles). It fits anchor 2 (domain named, actions minimal/generic); it is not entirely abstract like anchor 1, but lacks the 1-2 concrete actions required for anchor 3.

Completeness

Only the 'when' is present (two trigger clauses); the 'what' — what the skill actually does — is never stated, and the opening clause "Use when applies to all HTML pages" is malformed. Anchor 2 explicitly covers 'when' present without 'what'; anchor 3 requires a clear 'what', which is missing.

Trigger Term Quality

Some natural phrases are present ("auditing a site crawl report", "why multiple pages compete for the same keyword"), but the most central user terms — "duplicate titles", "title tag", "SEO" — are absent. This matches anchor 3 (relevant keywords but missing common variations or synonyms) rather than anchor 4's good coverage.

Distinctiveness Conflict Risk

The keyword-cannibalization scenario is somewhat specific, but because the words "title" and "SEO" never appear, the description could also fire for other SEO audit rules (canonical URLs, meta descriptions) triggered by "auditing a site crawl report". This is anchor 3 (somewhat specific but overlap risk with similar skills), not anchor 4's mostly-distinct profile.
