Quality

Content

42%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a thin catalogue/pointer entry rather than a self-contained skill: it advertises an upstream bundle and tells the agent to install it, but provides almost no executable guidance for the actual paywall/upgrade task. Organization is clean but actionability is the main weakness.

Suggestions

Replace the vague 'install the upstream bundle into your active agent's skills directory' with the concrete clone/copy command and target path.

Add at least one concrete, copy-paste-ready example of the skill's output (e.g., a sample paywall layout or upgrade-screen checklist) so the entry is actionable without the upstream bundle.

Remove the redundant 'What it does' section that duplicates the frontmatter description verbatim to tighten the body.

DimensionReasoningScore

Conciseness

The body is short and assumes Claude's competence, but the "What it does" section repeats the frontmatter description verbatim and the "How to use" prose could be tightened, so it is mostly efficient rather than fully lean.

2 / 3

Actionability

The only command is `open https://github.com/coreyhaines31/marketingskills`, which merely opens a browser; the actual instruction ("install the upstream bundle into your active agent's skills directory") gives no concrete, executable command, so it describes rather than instructs.

1 / 3

Workflow Clarity

A sequence is present (install the upstream bundle, then invoke the skill by name or trigger), but the install step has no concrete command and there are no validation checkpoints, so the sequence is present but vague with implicit gaps.

2 / 3

Progressive Disclosure

The skill is under 50 lines with no local bundle files, and the body is organized into clear, well-signaled sections (What it does, Source, How to use) that point one level deep to the upstream repo, matching the simple-skill allowance for a top score.

Description

82%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, distinctive, and rich in natural trigger terms, with proper third-person voice. Its main gap is the absence of an explicit 'Use when...' trigger clause, leaving the 'when to use' guidance implied rather than stated.

Suggestions

Add an explicit trigger clause such as 'Use when designing or optimizing paywalls, upgrade screens, upsell modals, or running pricing-page conversion experiments.'

Optionally surface the frontmatter trigger phrases inside the description so the 'when' guidance is self-contained.

DimensionReasoningScore

Specificity

The phrase 'Design and optimize upgrade screens, paywalls, and upsell modals' names multiple concrete actions (design, optimize) across several specific objects, matching the anchor that lists multiple specific concrete actions.

3 / 3

Completeness

It clearly answers 'what' ('Design and optimize upgrade screens, paywalls, and upsell modals') but the 'when' is only weakly implied via 'Useful for SaaS conversion design and pricing-page experiments' rather than an explicit 'Use when...' trigger clause, so completeness is capped at 2.

2 / 3

Trigger Term Quality

Natural user-facing terms are well covered both in the description ('upgrade screens, paywalls, upsell modals, pricing-page experiments') and in the frontmatter trigger list ('paywall', 'upgrade screen', 'cro paywall', 'upsell modal', 'pricing screen'), giving good coverage of phrases users would actually say.

3 / 3

Distinctiveness Conflict Risk

The paywall/upsell/CRO niche with distinct, specific triggers is clearly distinguishable and unlikely to fire for unrelated skills, matching the clear-niche anchor.
