Conciseness

The body is almost entirely curated tables and lists with no over-explanation of concepts Claude already knows, but "Implementation Tips" (By Stage / By Budget / By Timeline) and "Top Ideas by Use Case" repeat overlapping numbered idea sets, which is trimmable redundancy. This fits anchor 4 (efficient with minor instances that could be tightened) rather than anchor 5 (lean, every token earning its place).

Actionability

As an instruction-only skill, the concrete guidance is solid: a 4-step recommendation workflow, a structured output template ("Idea name / Why it fits / How to start: first 2-3 implementation steps / Expected outcome / Resources needed"), and specific context-gathering questions. It falls short of anchor 5 only because implementation detail for individual ideas is deferred to the reference file rather than exemplified inline.

Workflow Clarity

The sequence "Ask about their product, audience, and current stage if not clear → Suggest 3-5 most relevant ideas → Provide details on implementation → Consider their resources" is clear and ordered, and the pre-check for `.claude/product-marketing-context.md` is a useful checkpoint. It matches anchor 4 (clear sequence, minor validation gaps) — no destructive or batch operations apply the cap, but there are no explicit verify/retry checkpoints that would justify a 5.

Progressive Disclosure

The body is a true overview (quick-reference category table plus curated subsets) with a single, clearly signaled, one-level-deep reference — "For the complete list with descriptions: See [references/ideas-by-category.md](references/ideas-by-category.md)" — which exists in the bundle and holds the full 139-item list. This matches the anchor-5 pattern of a concise overview with well-signaled flat references.

Specificity

"This skill provides 139 proven marketing approaches organized by category" names the domain and one concrete deliverable, but unlike the anchor-4 example it does not enumerate multiple distinct actions (e.g., generating idea lists, tailoring recommendations by stage/budget). It sits above anchor 2 (the domain and deliverable are concrete) and below anchor 4 (only one capability is named).

Completeness

It explicitly answers both questions: "When the user needs marketing ideas, inspiration, or strategies for their SaaS or software product" plus "Also use when the user asks for..." (when), and "This skill provides 139 proven marketing approaches organized by category" (what), with concrete trigger phrases as in the anchor-5 example. It is above anchor 4 because the "when" clause is fully explicit, not merely adequate.

Trigger Term Quality

Quoted triggers — "marketing ideas," "growth ideas," "how to market," "marketing strategies," "marketing tactics," "ways to promote," "ideas to grow" — comprehensively cover the natural synonyms a user would say when needing this skill, matching the anchor-5 example's breadth (file extensions are inapplicable to a non-file skill).

Distinctiveness Conflict Risk

Scoping to "SaaS or software product" marketing gives a clear niche, but broad phrases like "marketing strategies" and "ways to promote" carry minor overlap risk with closely related marketing sub-skills (SEO, email marketing). It is below anchor 5 (triggers are not uniquely discriminative) and above anchor 3 (the SaaS/software scope plus idea-generation framing is genuinely distinct).
