popup-cro

When the user wants to create or optimize popups, modals, overlays, slide-ins, or banners for conversion purposes. Also use when the user mentions "exit intent," "popup conversions," "modal optimization," "lead capture popup," "email popup," "announcement banner," or "overlay." For forms outside of popups, see form-cro. For general page conversion optimization, see page-cro.

Quality

Content

56%Weight 40%Scale 1-5

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

The body is well-organized with genuinely valuable non-obvious specifics (trigger timing numbers, conversion benchmarks, frequency caps, compliance and Google interstitial notes) and a clear assessment-to-output workflow. However, roughly a third of it restates UX/copy knowledge Claude already possesses, and the monolithic 450-line SKILL.md inlines reference material that should be split into bundle files.

Suggestions

Cut the "Core Principles" section and trim "Design Best Practices" and "Copy Formulas" to only non-obvious specifics (trigger timing numbers, sizing ranges, mobile exit-intent limitation, first-person CTA finding) — Claude already knows generic popup/UX conventions.

Trim the ~90-line "Experiment Ideas" section down to a handful of high-value tests per popup type rather than an exhaustive bullet enumeration of variations Claude can generate on demand.

Split reference material (Popup Types details, Experiment Ideas, Common Popup Strategies) into separate bundle files (e.g., references/popup-types.md, references/experiments.md) with one-level-deep pointers, keeping SKILL.md focused on the assessment workflow and output format.

DimensionReasoningScore

Conciseness

Of ~450 lines, roughly a third restates knowledge Claude already has — "Core Principles" ("Too early = annoying interruption", "Don't trap or trick"), generic design conventions (close button placement, touch targets), and a ~90-line Experiment Ideas section enumerating trivial variations ("Test with/without images", "Button color testing"). This is noticeably verbose with several padded sections.

2 / 5

Actionability

Concrete, specific guidance throughout — "Show after 30-60 seconds", "25-50% scroll depth", "Desktop: 400-600px wide", "7-30 days before showing again", benchmarks ("Email popup: 2-5% conversion typical"), copy examples, and a defined Output Format. Falls short of 5 only because there is no complete worked example of a full popup specification.

4 / 5

Workflow Clarity

The process has an explicit entry point (read product-marketing-context.md, then "Before providing recommendations, understand: …" and Task-Specific Questions) and an explicit exit point (Output Format, Test Hypotheses), with the middle organized as topical reference. This is advisory, non-destructive work, so no validation checkpoints are required.

4 / 5

Progressive Disclosure

Section headers are clear, but all ~450 lines live inline in SKILL.md with no bundle files; Popup Types deep-dives, Design Practices, Common Popup Strategies, and Experiment Ideas are reference material that clearly belongs in separate files, matching the anchor for structure present but content that should be separate is inline.

Description

90%Weight 40%Scale 1-5

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

A strong description with explicit what/when guidance, comprehensive natural trigger phrases, and explicit boundary disambiguation against related skills. The only weakness is that the capability list is thin — 'create or optimize' are generic verbs — leaving the reader to infer the skill's full scope from the body.

DimensionReasoningScore

Specificity

The description names the domain thoroughly ("popups, modals, overlays, slide-ins, or banners") but lists only two actions ("create or optimize"), matching the anchor for naming a domain with 1-2 concrete actions rather than listing several specific capabilities.

3 / 5

Completeness

It explicitly answers both what ("create or optimize popups, modals, overlays, slide-ins, or banners for conversion purposes") and when ("When the user wants to…" plus "Also use when the user mentions…" with concrete quoted trigger phrases), matching the top anchor.

5 / 5

Trigger Term Quality

It comprehensively covers natural terms users would say, including synonyms (popups, modals, overlays, slide-ins, banners) and quoted phrases like "exit intent," "popup conversions," "lead capture popup," "email popup," and "announcement banner."

5 / 5

Distinctiveness Conflict Risk

It carves out a clear niche with distinct trigger terms and explicitly disambiguates sibling skills ("For forms outside of popups, see form-cro. For general page conversion optimization, see page-cro."), minimizing conflict risk.
