Conciseness

The core protocol content is dense and skill-specific — the diagnosis table, taste-reading rules, decompose-and-lock, three-question gate, AI-tells rules, and the claims-decline protocol are all non-obvious and compressed. However, the "Best Practices" section ("Be Direct," "Use Analogies When Helpful," "Pepper in Humor") and "Voice and Tone" restate copywriting fundamentals Claude already knows, which is more than the "minor instances" of the 5 anchor but far from the padding of the 3 anchor's unnecessary explanation — the bulk of every token-heavy section earns its place.

Actionability

For an instruction-only skill the guidance is fully executable: a three-situation diagnosis table with a required one-line evidence statement, named drafting units with candidate counts, a three-question gate with numeric pass thresholds ("Three passes, keep it. Two, sharpen the weak one"), banned patterns with rewrite instructions ("State a real absence once, near the CTA"), CTA formulas with examples, a flagging convention ([NEED: ...]), and a specified output format with alternatives. This matches the fully-actionable top anchor.

Workflow Clarity

The sequence is clear and ordered: check product-marketing context → gather four context areas → diagnose (state it in one line with evidence) → decompose and lock units → gate every line → ration the punch → leave-it-alone test → pre-delivery self-check (search banned patterns, read sentences over 20 words, read aloud) → output format. Explicit validation checkpoints exist at drafting (three-question gate) and delivery (self-check, leave-it-alone test), with error-recovery paths ("rewrite it from the facts or flag what's missing"), matching the top anchor with explicit validation and feedback loops.

Progressive Disclosure

The body keeps the core workflow inline and offloads bulk detail to three real, one-level-deep reference files, each clearly signaled with inline markdown links and verified section anchors (references/ai-tells.md#the-self-check, #build-a-writer; references/copy-frameworks.md#clarity--message-market-fit; references/natural-transitions.md). Cross-links between sibling references are lateral pointers, not chained nesting, so navigation is easy and content is appropriately split — matching the top anchor.

Specificity

Concrete actions are named explicitly: "write, rewrite, or improve marketing copy" with the page types enumerated ("homepage, landing pages, pricing pages, feature pages, about pages, or product pages"), plus concrete behaviors such as declining unsupported claims and diagnosing the input type. Coverage is comprehensive with no generic filler, matching the anchor for multiple specific concrete actions.

Completeness

Both what and when are explicit: "When the user wants to write, rewrite, or improve marketing copy..." (what/when combined) and "Also use when the user says [15 concrete trigger phrases]" (explicit when with concrete triggers). This matches the anchor for clearly and explicitly answering both questions with concrete trigger phrases; the 4 anchor would require the when to be less explicit.

Trigger Term Quality

Fifteen-plus natural trigger phrases users would actually say: "write copy for," "improve this copy," "marketing copy," "headline help," "CTA copy," "value proposition," "tagline," "hero section copy," "this copy is weak," "this sounds like AI," "AI slop," "make it sound human," "help me describe my product." Coverage includes colloquial variants and synonyms, matching the comprehensive-coverage anchor; not the 4 anchor since only peripheral terms like "sales page" or "web copy" are absent.

Distinctiveness Conflict Risk

Clear niche (page marketing copy) with explicit routing to sibling skills: "For email copy, see emails. For popup copy, see popups. For editing existing copy, see copy-editing. For the offer underneath the copy (bonuses, guarantees, value framing), see offers." The overlap cases are pre-empted by routing, so conflict risk is minimal, matching the distinct-triggers anchor.
