Conciseness

The body is lean and dense — a compact platform table, failure signatures stated in one line each, and no explanation of concepts Claude already knows (e.g., what a pixel or CAPI is). Every sentence carries operational information, matching the lean/efficient 5 anchor.

Actionability

Guidance is fully concrete for an instruction-only skill: named tool calls (get_pixel_health, ga4_get_report, get_attribution, get_spend_reconciliation), exact click-ID parameters and tag markers per platform, per-platform dedup event-ID fields, failure signatures with diagnosis, EMQ thresholds (6+ healthy, below 5 problematic), and a precise hashing recipe (SHA-256 of lowercased, trimmed value).

Workflow Clarity

Six clearly sequenced audit phases with explicit validation and feedback loops: "repeat the test" after tag fixes, "repeat a test conversion before scaling", failure signatures as diagnostic checkpoints, and "mark unavailable evidence as unverified". This matches the explicit-validation-with-error-recovery 5 anchor.

Progressive Disclosure

The single-file body is well organized with clear sections and nothing inlined that belongs in separate files, but the closing "See **conversion-tracking**" pointer is not a clearly signaled path or link and no such bundle file exists — a minor organization gap that fits the 4 anchor rather than 5.

Specificity

"Audit client-side pixels and server-side Conversions API implementations" plus "setup, Event Match Quality, deduplication, and click-ID capture" lists multiple concrete actions with comprehensive coverage across six named platforms, matching the comprehensive anchor; it is not 4 because there are no notable coverage gaps.

Completeness

The description explicitly answers both what ("Audit client-side pixels and server-side Conversions API implementations... setup, Event Match Quality, deduplication, and click-ID capture") and when ("Use when conversion counts disagree... EMQ or match rates are low, or tracking needs verification before scaling spend") with concrete trigger phrases, matching the 5 anchor exactly.

Trigger Term Quality

"Use when conversion counts disagree between platforms, EMQ or match rates are low, or tracking needs verification" provides good natural phrasing, but common variations like "duplicate conversions", "pixel not firing", or "attribution mismatch" are absent, so it falls short of the comprehensive-synonym 5 anchor.

Distinctiveness Conflict Risk

The niche is clear — pixel/CAPI auditing named per platform (Meta, Google, TikTok, LinkedIn, Reddit, Microsoft) with domain-specific triggers like EMQ, deduplication, and click-ID capture — so conflict risk with other skills is minimal.
