launch-landing-page

Design and build launch landing pages that convert visitors into users. Use this skill whenever someone asks to create a landing page for a product launch, build a feature page, design a signup page, or structure a product marketing page. Also trigger for "make a page for this launch," "I need a landing page," "help me design the product page," or any request to create a web page tied to a product release or feature announcement. Covers page structure, hero design, SEO integration, developer-first patterns, urgency mechanics, waitlist flows, and conversion optimization.

Quality

Content

65%

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

A thorough, actionable design guide with concrete examples and good internal structure, but it carries some general marketing/SEO knowledge Claude already knows and keeps everything in one monolithic file rather than splitting detail into references. Workflow steps are sequenced but lack explicit validation gates.

Suggestions

Trim general-knowledge truisms (page-speed conversion stats, title-tag/meta-description character limits, "visitors scan not read") to tighten conciseness, keeping only launch-specific decision guidance.

Add explicit validation checkpoints to the build workflow — e.g., gate adding supporting sections on the hero passing the 5-second test, and verify mobile CTA tappability before shipping.

Split dense reference material (detailed SEO integration and the pre/launch/post-launch state tables) into separate reference files linked from a concise overview, improving progressive disclosure.

DimensionReasoningScore

Conciseness

Mostly efficient actionable guidance, but it re-states general knowledge Claude already has (load time costing ~7% of conversions, title tags under 60 chars, meta descriptions 150-160 chars, "most visitors scan, not read"), so not every token earns its place.

2 / 3

Actionability

For an instruction-only skill it gives concrete, specific guidance with copy-paste-ready example copy ("Free for the first 1,000 users," "You're #847 on the waitlist"), defined section structures, a layout order, and a 5-second test — no vagueness or missing key details.

3 / 3

Workflow Clarity

Sequences exist (the "Building the page" checklist and the pre-launch/launch-day/post-launch phases), but there are no explicit validation checkpoints or feedback loops; the 5-second test is framed as a tip rather than a gating step.

2 / 3

Progressive Disclosure

Internally well-organized with clear headers, but it is a monolithic ~170-line SKILL.md with no reference files, and content that could be split (SEO integration, launch-state patterns) is kept inline.

Description

100%

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, well-scoped description that clearly states what the skill does, when to trigger it, and the natural phrases a user would say, all in third person without padding. It is comprehensive yet concise.

DimensionReasoningScore

Specificity

Lists multiple concrete actions and sub-tasks — "Design and build launch landing pages" plus an explicit coverage list (page structure, hero design, SEO integration, urgency mechanics, waitlist flows, conversion optimization).

3 / 3

Completeness

Explicitly answers both what ("Design and build launch landing pages that convert visitors into users") and when ("Use this skill whenever… Also trigger for…"), with explicit trigger guidance.

3 / 3

Trigger Term Quality

Packs in natural user phrasing — "create a landing page for a product launch," "build a feature page," "design a signup page," "make a page for this launch," "I need a landing page," "help me design the product page" — with strong common-variation coverage.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche — launch-specific landing pages — with triggers scoped to page creation tied to product launches/feature announcements, distinct from the companion launch skills.
