Conciseness

The body is dominated by terse tables and numbered idea references with no explanation of concepts Claude already knows, but the "By Budget" and "By Timeline" sections are generic ("Quick wins: Ads, email, social posts" carries no idea numbers) and duplicate categories already indexed elsewhere. Matches anchor 4 (efficient, minor instances that could be trimmed); not anchor 5 since not every token earns its place, and not anchor 3 since there is no unnecessary explanation.

Actionability

Concrete instruction-style guidance throughout: "Suggest 3-5 most relevant ideas based on their context," a five-field output format (Idea name / Why it fits / How to start / Expected outcome / Resources needed), and four specific intake questions. Not anchor 5 because there is no worked example of a rendered recommendation and "How to start" details depend on the one-line idea descriptions in the reference file; not anchor 3 because the guidance is specific and executable, not pseudocode-level.

Workflow Clarity

A clear numbered sequence (ask context → suggest 3-5 ideas → detail implementation → weigh resources) preceded by a gating step ("read it before asking questions... only ask for information not already covered"), with the output format acting as a completion checklist. Not anchor 5 because there are no explicit validation or feedback checkpoints; the anchor-3 cap for missing validation does not apply since the skill is advisory, not destructive or batch.

Progressive Disclosure

The body is a genuine overview/index — a 17-category quick-reference table, stage/budget/timeline slices, and use-case picks — with both referenced files verified to exist and exactly one level deep (ideas-by-category.md holds the full 139-idea list; guerrilla-marketing.md the single deep dive, clearly signaled with a content summary). Matches anchor 5 (clear overview, well-signaled one-level-deep references, easy navigation).

Specificity

"needs marketing ideas, inspiration, or strategies for their SaaS or software product" names the domain and deliverables, but the description never states concrete skill actions (e.g., suggesting or detailing ideas) — those appear only in the body. Falls between anchor 2 (minimal/generic actions) and anchor 3 (domain plus 1-2 concrete actions); not anchor 4 since no specific action list is present.

Completeness

Both halves are explicit: the what ("needs marketing ideas, inspiration, or strategies... Use this as a starting point") and an exhaustive when with concrete trigger phrases ("Also use when the user asks for 'marketing ideas,' 'growth ideas,'..."). Clearly matches the anchor-5 example structure; anchor 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

Eleven quoted natural phrases ("marketing ideas," "how to market," "ways to promote," "what else can I try," "I don't know how to market this") plus a "stuck or looking for inspiration" clause give strong coverage, but common SaaS-founder phrasings like "how to get more users," "user acquisition," or "growth hacking" are missing — matching anchor 4 (a few natural terms missing) rather than anchor 5 (comprehensive).

Distinctiveness Conflict Risk

The explicit carve-out "For specific channel execution, see the relevant skill (ads, social, emails, etc.)" reduces conflict, and the SaaS-marketing niche is clear, but the broad "whenever someone is stuck or looking for inspiration on how to grow" trigger and closely related sibling skills (e.g., marketing-plan) create minor overlap risk — anchor 4 rather than anchor 5.
