Conciseness

The body is mostly lean — terse tables, formulas, and rules ("Impact → Higher is better", "Never recommend ideas with MFS ≤ 0") with no explanation of concepts Claude already knows. Not 5 because the trailing "When to Use: This skill is applicable to execute the workflow or actions described in the overview." is vacuous filler and the rules in sections 3 and 7 repeat each other ("No idea dumping" vs "Do not dump long lists", "No unscored recommendations"); not 3 because the padding is minor, not several unnecessary explanations.

Actionability

The mechanics are concrete — the formula "MFS = (Impact + Fit + Speed) − (Effort + Cost)", the -7→+13 range, interpretation bands, a worked example, and a required output template — but section 4 "The Marketing Idea Library (140)" is only a placeholder ("Library unchanged; same ideas as previous revision, omitted here for brevity but assumed intact in file."), and no library file exists in the bundle, so the core shortlisting step cannot actually be executed. Not 4 because the missing 140-idea library is a central gap, not a minor one; not 2 because the scoring and output guidance is specific and directly usable.

Workflow Clarity

Section 1 sequences the full process (establish context with "ask if missing" → shortlist 6-10 → score with MFS → operationalize with first steps and success metrics), reinforced by mandatory rules ("Never recommend ideas with MFS ≤ 0", "Never recommend more than 5 ideas") and stage-based scoring biases in section 6. Not 5 because there are no explicit checkpoints for ambiguous or conflicting user context (e.g., what to do when stated budget contradicts the stage); not 3 because the sequence and checkpoints are explicit rather than implicit, and the skill is advisory rather than destructive/batch so no validation cap applies.

Progressive Disclosure

Sections are clearly numbered and organized, but the skill's central asset is a dangling reference: section 4 points to a library "assumed intact in file" while no references/ directory or any bundle file exists, so navigation fails at the most important pointer. Not 4 because a claimed external file is missing entirely; not 2 because the body itself is well-structured with headers, not a monolithic wall of text.

Specificity

The description names the domain ("SaaS and software products") and two actions ("Provide proven marketing strategies and growth ideas", "prioritized using a marketing feasibility scoring system"), which matches the anchor for 1-2 concrete actions without comprehensive coverage. Not 4 because it omits the fuller capability set the body actually performs (shortlisting from a library, stage-based scoring bias, required output format); not 2 because it goes beyond merely naming the domain.

Completeness

The 'what' is clear (provide and prioritize marketing/growth ideas via a feasibility scoring system) but there is no 'Use when...' clause or equivalent trigger guidance anywhere in the description, which per the judging guidelines caps completeness at 3. Not 4 because the 'when' is entirely absent rather than merely under-specified.

Trigger Term Quality

"marketing strategies", "growth ideas", and "SaaS" are natural terms a user would say when needing this skill, giving good keyword coverage. Not 5 because common variations like "growth hacking", "customer acquisition", "go-to-market", or "user growth" are missing; not 3 because coverage is solid rather than partial.

Distinctiveness Conflict Risk

The "SaaS and software products" focus plus the feasibility-scoring mechanism carves a mostly distinct niche with only minor overlap risk against generic marketing or growth-strategy skills. Not 5 because no explicit trigger phrases sharpen the distinction further; not 3 because the SaaS focus and named scoring system make it more specific than 'somewhat specific'.
