Conciseness

The body is dense and navigational (tables, categorized lists, numbered workflow) with no explanations of concepts Claude already knows. Minor trimming opportunities exist: the ~40-word guerrilla-marketing deep-dive paragraph restates content from the reference file, and the 'By Budget'/'By Timeline' sections repeat category names already in the quick-reference table. Not score 5 because not every token earns its place; not score 3 because the padding is minor, not 'several unnecessary explanations.'

Actionability

For an instruction-only skill the guidance is fully actionable: a numbered process ('1. Ask about their product, audience, and current stage if not clear... 2. Suggest 3-5 most relevant ideas'), a concrete per-idea output format ('Idea name / Why it fits / How to start / Expected outcome / Resources needed'), exact discovery questions, a pre-check for the product-marketing context file, and numbered idea IDs (#31, #93) keyed into the reference list.

Workflow Clarity

The sequence is clear and ordered (read context file first, ask if not clear, suggest 3-5 ideas, detail chosen ideas, weigh resources), including a conditional gather-requirements gate. It scores 4 rather than 5 because there are no explicit validation/checkpoint steps in the workflow; 5's anchor ('explicit validation steps; feedback loops') is not met, though this ideation skill has no destructive or batch operations that would trigger the validation cap.

Progressive Disclosure

The body is a clear overview/index and both referenced files exist and match their in-body descriptions: references/ideas-by-category.md ('For the complete list with descriptions') and references/guerrilla-marketing.md (deep-dive summary). References are one level deep, well-signaled with markdown links and stated purpose, and the bulk idea content is appropriately split out of SKILL.md.

Specificity

The description names the domain and deliverable clearly ('marketing ideas, inspiration, or strategies for their SaaS or software product', 'a starting point') but does not list several distinct concrete actions the skill performs. It matches 'names domain and 1-2 concrete actions' better than score 4 ('lists several specific actions') because the capability is expressed as a single conceptual deliverable.

Completeness

Both what and when are explicitly answered with concrete trigger phrases: what ('a starting point' supplying 'marketing ideas, inspiration, or strategies' for SaaS/software) and when ('Use this as a starting point whenever someone is stuck or looking for inspiration on how to grow'). The 'when' could not be more explicit, so score 4's caveat does not apply.

Trigger Term Quality

Extensive natural trigger phrases including synonyms and colloquial variants users would actually say: 'marketing ideas,' 'growth ideas,' 'how to market,' 'ways to promote,' 'what else can I try,' 'I don't know how to market this,' 'brainstorm marketing.' Coverage is comprehensive; no common variation is obviously missing.

Distinctiveness Conflict Risk

Clear niche (marketing ideation/brainstorming for SaaS) with distinct triggers, plus explicit boundary guidance: 'For specific channel execution, see the relevant skill (ads, social, emails, etc.)' actively routes away from adjacent execution skills, minimizing conflict risk.
