Conciseness

Mostly efficient and free of basic-concept padding, but command listings are repeated across 'Typical Analysis Workflow', 'How to Use', and 'Scripts' sections, and tool descriptions overlap with the model table. Not a 4 because the redundancy is noticeable rather than minor; not a 2 because no section is pure fluff.

Actionability

Provides concrete, copy-paste-ready commands with real flags (e.g. 'python scripts/attribution_analyzer.py campaign_data.json --model time-decay --half-life 14') plus full JSON input schemas. Not a 5 because the referenced scripts are absent from the bundle, so commands cannot actually execute without those files; not a 3 because the guidance form itself is complete and specific.

Workflow Clarity

Clear three-step sequence in 'Typical Analysis Workflow' with a pre-run JSON validation checkpoint ('python -m json.tool') and an error-to-exception mapping that aids recovery. Not a 5 because there is no explicit validate→fix→retry feedback loop for script failures; not a 3 because a validation checkpoint and error guidance are present.

Progressive Disclosure

In-document structure is good — a 'Reference Guides' table signals one-level-deep references to three guides — but every referenced bundle path (scripts/*.py, references/*.md, assets/sample_campaign_data.json) is missing from the actual bundle, leaving dangling references. Not a 4 because broken/missing reference files are more than a minor organization gap; not a 2 because the SKILL.md itself is well sectioned and the references are clearly signaled.

Specificity

Lists several concrete actions — 'multi-touch attribution', 'funnel conversion analysis', and 'ROI calculation' — but stops short of the comprehensive multi-action coverage of the 5-anchor; not a 5 because 'marketing optimization' is a generic tail rather than another concrete capability.

Completeness

Explicitly answers both what ('Analyzes campaign performance with multi-touch attribution, funnel conversion analysis, and ROI calculation') and when ('Use when analyzing marketing campaigns, ad performance, attribution models, conversion rates, or calculating marketing ROI, ROAS, CPA...'). Matches the 5-anchor's what+when-with-concrete-triggers; not a 4 because the 'when' is fully explicit, not merely present.

Trigger Term Quality

Comprehensive natural-term coverage including acronyms users actually say — 'marketing campaigns, ad performance, attribution models, conversion rates', plus 'ROI, ROAS, CPA' and 'campaign metrics across channels'. Not below 5 because the term set is broad and matches how a user would phrase the need.

Distinctiveness Conflict Risk

Occupies a clear campaign-analytics niche with distinct marketing-specific triggers (attribution models, ROAS, CPA) and minimal overlap with adjacent skills. Not below 5 because the triggers are specific enough to avoid firing for unrelated analytics skills.
