Conciseness

The core rules are lean and terse, but the body includes unnecessary content: a ~10-line promotional footer ('Want this skill (and 40+ more) running on autopilot... Try Synter') with UTM-tagged marketing links unrelated to skill execution, and minor over-explanation of campaign status definitions Claude already knows. This matches 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than the minor-trim level of 4.

Actionability

For an instruction-only skill the guidance is fully actionable: an exact formula ('CPA = total spend / conversions'), a copy-paste response template with section structure, and worked DO/DON'T examples with real numbers ('71 conversions at $280 CPA, but HubSpot only attributes 3 leads') covering the common cases. This matches the top anchor despite the absence of code, per the code-vs-instruction scoring note.

Workflow Clarity

A clear sequence is present via the Standard Analysis Template and the numbered 4-step 'When in Doubt' procedure with a source-of-truth checkpoint. It falls short of 5 because there is no verification step to confirm a suspected root cause (e.g., actually checking whether UTM parameters are present before declaring tracking broken) — a minor validation gap matching anchor 4.

Progressive Disclosure

The skill has no bundle files and ~107 lines organized into clear, well-labeled sections with no nested references; nothing clearly belongs in a separate file. It exceeds the 50-line simple-skill threshold and carries a minor organization gap (the off-topic promo footer sits inline after the operational content), matching anchor 4 rather than 5.

Specificity

The description lists several concrete capabilities — 'Comparing ad-platform performance with CRM', 'UTM/pixel issues', 'data-source hierarchy and gap diagnosis' — placing it at 'several specific actions; minor gaps'. It falls short of 5 because items like 'last-click vs data-driven' name concepts rather than actions, and above 3 because it covers more than 1-2 concrete actions.

Completeness

The 'what' is clear (compare ad-platform performance with CRM, diagnose attribution gaps), but there is no 'Use when...' clause or equivalent explicit trigger guidance — the quoted symptom phrase only weakly implies when to invoke the skill. Per the rubric guideline, a missing explicit trigger caps completeness at 3.

Trigger Term Quality

Good keyword coverage including the verbatim natural phrase 'ad platform shows conversions but CRM shows zero' plus 'attribution gaps', 'UTM/pixel issues', and 'last-click vs data-driven'. A few natural terms users might say are missing (e.g., 'conversion tracking', 'discrepancy between platforms'), so it sits between anchors 4 and 5, closer to 4.

Distinctiveness Conflict Risk

The description carves out a clear niche (ad-platform vs. CRM attribution reconciliation) with a highly distinct trigger phrase ('ad platform shows conversions but CRM shows zero'), making conflict with other skills minimal — a direct match to the anchor-5 example's pattern.
