Conciseness

The per-principle "Core concept" and "Why it works" paragraphs (e.g., "People feel obligated to give back to others who have given to them first") re-explain Cialdini's principles, which Claude already knows, and the "About the Author" biography plus affiliate-linked "Further Reading" section are padding. Not a 2 because the application tables, copy patterns, and checklists are dense, curated content where nearly every token earns its place; not a 4 because the known-concept re-explanation spans all seven principle sections.

Actionability

For an instruction-only skill the guidance is fully actionable: copy-paste-ready copy patterns ("Here's a gift for you...", "Only 3 spots left at this price"), concrete product-application tables with real examples (Spotify, Dropbox, Grammarly), a defined 0-10 scoring procedure ("Always provide the current score and specific improvements needed to reach 10/10"), and a worked SaaS landing-page example combining principles. Specific examples cover the common cases, matching the 5 anchor.

Workflow Clarity

The Quick Diagnostic table (Question / If No / Action) and the Ethical Application Checklist ("Before deploying influence tactics") provide sequence-like checkpoints with feedback paths, and the onboarding sequence under Commitment is stepwise. Not a 5 because there is no explicit end-to-end workflow ordering the pieces (e.g., audit -> score -> improve -> validate) — the review process must be assembled implicitly from the Scoring, Diagnostic, and Checklist sections.

Progressive Disclosure

Verified against the actual bundle: all 10 inline references ("See: [references/reciprocity.md]...") point to real files, each ~250-290 lines, exactly one level deep with no nested references, plus a consolidated "Reference Files" index with per-file descriptions. The SKILL.md keeps overview-level application tables inline and pushes deeper material (gift strategies, copy templates, case studies) to the references — a clear, well-signaled structure matching the 5 anchor.

Specificity

Enumerates the six principles by name ("reciprocity, commitment, social proof, authority, liking, scarcity") and concrete application targets ("product design, copy, and sales", "testimonial sections", "urgency messaging", "trust signals on landing pages"). This is comprehensive, specific coverage of the skill's capabilities rather than vague domain naming, matching the 5 anchor; the 4 anchor ('minor gaps in coverage') fits less well since both principles and contexts are enumerated.

Completeness

Explicitly answers what ("Apply the six principles of ethical persuasion... to product design, copy, and sales") and when ("Use when the user mentions..."; "Also trigger when designing testimonial sections..."), mirroring the 5-anchor example structure with concrete trigger phrases. It clearly exceeds the 4 anchor, where the 'when' would be less explicit.

Trigger Term Quality

Seven natural quoted phrases ("social proof", "persuasive copy", "why users dont convert", "ethical persuasion", "reciprocity", "scarcity tactics", "commitment and consistency") plus behavioral triggers give good keyword coverage a user would plausibly say. Not a 5 because common variations like "Cialdini", "influence principles", "persuasion techniques", or "conversion optimization" are missing.

Distinctiveness Conflict Risk

The persuasion-psychology niche is distinct and the description actively reduces conflict risk by redirecting adjacent topics ("For deal negotiation tactics, see negotiation. For viral word-of-mouth, see contagious."). Clear niche with distinct triggers and minimal conflict risk matches the 5 anchor.
