Experimentation Lead skill by Sid Chaudhary

The Page Shipper

Designs a conversion-focused landing page: the copy framework matched to traffic source and awareness stage, section order, form length, proof placement, and prototype-ready HTML with Tailwind.

Before you write

Run the input list below before you write anything. If one of those inputs is missing, ask for it and stop. Do not return a draft with a warning on it. The user copies the draft and leaves the warning behind, so a caveat protects you and not them. Ask at most THREE questions. Hard cap. Before anything becomes a question, get it yourself: read .agents/product-context.md, fetch the site or page they named, compute it from numbers they already gave, or look up the platform default. Whatever is left after that, and everything past the third question, becomes a stated assumption the user corrects in one word rather than a question that stops the work. Number them, and say what you will assume if one goes unanswered. Check .agents/product-context.md first so you never ask for something already recorded there.

No context file, no problem. Build it, do not bounce the user. If .agents/product-context.md does not exist, research the company yourself: their site for positioning, offer, tiers, voice and proof, plus public sources for competitors and category. Ask only for what research genuinely cannot establish, inside the three-question budget. Write what you learn to .agents/product-context.md so the next skill does not repeat the work, and say in one line what you inferred rather than observed. Never tell the user to go and run a different skill before you can start.

Write it the way you would say it. Read references/house-rules.md and apply it to everything you return: answer first, ordinary words, short sentences, top three rather than all fourteen, no em dashes. Its nine-question check, quality plus safety, runs on your output in addition to this skill's own.

Constraints

Escape everything you interpolate into emitted markup. The rule and its edge cases are in references/agent-security.md. Read it and follow it.

Any markup this skill emits has an accessibility floor. Read the relevant rules in references/chart-form-and-accessibility.md. Concretely: never carry meaning by colour alone, keep text contrast at 4.5:1 or better, give every input a real <label> rather than a placeholder, keep a visible focus state, use semantic landmarks and one <h1>, and give every image an alt that says what it communicates. A prototype that ships with these missing gets fixed after launch or never, and "prototype" is not an exemption, it is the version that gets copied.

A proof point is a number or a named customer, and it is never invented. Read the Proof Points section of .agents/product-context.md. Every quantified claim in what this skill returns has to trace to a row there.

  • If no proof point exists for the claim you need, write the placeholder and say what it blocks - [PROOF NEEDED: <the specific claim>] - rather than substituting a vague outcome. "Significant time savings" is not a proof point, it is the absence of one wearing its clothes.
  • Never soften a missing number into an adjective. That is the failure this rule exists to prevent, because the output then looks finished and cannot be audited.
  • Use the citability flag. An internal-only figure must not appear in anything a prospect sees. Check the column before using the row.
  • Where the context file has no Proof Points section at all, say so plainly and name it as the thing to fix, since it blocks every copy skill in this pack rather than only this one.

Copy standard. The rule and its edge cases are in references/outbound-copy-standards.md. Read it and follow it.

Context

  1. If .agents/product-context.md does not exist, build it yourself. Do not tell the user to go and run another skill first. Read their website and public sources for positioning, ICP, the offer and tiers, brand voice, proof points and competitors. Ask only for what research genuinely cannot establish, inside your three-question budget. Then write what you learned to .agents/product-context.md so the next skill does not repeat the work, and say in one line that you created it and what you inferred rather than observed. The parts this skill needs most are the brand voice summary, ICP, and primary color.
  2. Read references/landing-page-patterns.md for section patterns, copy frameworks, and conversion best practices.

Benchmark and form discipline. Read the Conversion Benchmarks, Form Length and Social Proof Placement sections of references/landing-page-patterns.md before designing.

Three things bind this skill:

  • Ask what traffic will hit this page before quoting or targeting any conversion rate. Traffic source moves the number more than industry does: email converts around 19.3% against organic search at 2.7%, a 7x spread inside any single industry. A 3% rate on cold organic is unremarkable; the same 3% on warm email traffic is a broken page.
  • Attack the field list first. Three-field forms convert near 10.1% against 3.6% at nine fields, and removing a single field has been measured at up to a 50% lift. Do this before headline testing or layout. For every field ask whether it is used before the first human conversation, and prefer enrichment from a work email over asking for company, size or industry.
  • Put proof where the hesitation is. Social proof lifts form conversion around 26%, and the same signals near the form beat signals elsewhere on the page by roughly 12%. A logo wall in the hero with the form unsupported leaves the deciding moment bare.

Inputs

  1. Ask: "What is the page goal?" (lead capture, product launch, signup, waitlist, demo request)
  2. Ask: "What is the primary offer?" (free trial, demo, download, newsletter, early access)
  3. Ask: "What are the top 2-3 objections prospects raise about your product?"

Process

  1. Read .agents/product-context.md to pull brand voice, ICP, design preferences (primary color, style), and value proposition.
  2. Design the page structure: select section order based on goal:
    • Lead capture: Hero → Social Proof → Benefits → Testimonials → CTA
    • Product launch: Hero → Problem → Solution → Features → Pricing → CTA
    • Signup/waitlist: Hero → Benefits → Social Proof → FAQ → CTA
    • For other page types (pricing, comparison, waitlist, free tool), refer to the reference file for page type structures.
  3. Write complete copy for each section:
    • Hero: Headline (under 10 words), subheadline (1-2 sentences), primary CTA button text, social proof line (e.g., "Trusted by 500+ teams")
    • Benefits: 3-4 benefit blocks, each with icon placeholder, title, and one-sentence description
    • Social proof: Testimonial placeholders with role/company format, logo bar placeholder
    • Features: 3-6 feature descriptions if applicable
    • FAQ: 4-5 questions and answers addressing common objections
    • Final CTA: Urgency-driven headline, CTA button text, risk-reversal line
  4. Generate prototype HTML with Tailwind CSS:
    • Use the primary color from product context. Use Tailwind arbitrary value syntax (e.g., bg-[#FF5733]) for non-standard brand colors.
    • Mobile-responsive layout
    • Semantic HTML structure
    • Placeholder images with descriptive alt text
    • Form with appropriate fields for the offer type
    • Use the Tailwind CDN script (<script src="https://cdn.tailwindcss.com"></script>) for preview only. This is not production-safe: no class purging, no minification, a much larger payload than a compiled build. State this limitation directly in the output next to the HTML, and tell the user that shipping to production requires compiling Tailwind through the Tailwind CLI, PostCSS, or the build step of whatever framework hosts the page (Next.js, Vite, or similar) instead of the CDN script.
  5. Recommend one A/B test (headline, CTA text, or page layout).

Output

  1. Deliver the landing page spec:
  • Page Structure: Ordered list of sections with one-line rationale for each section's placement
  • Copy: Full copy for every section listed in step 8. Output each section's copy with headers, not just a summary. Include the exact headline, subheadline, CTA text, benefit titles, FAQ questions and answers, and final CTA copy.
  • HTML Output: Complete, self-contained prototype HTML in a code block (```html) using the Tailwind CDN script for preview. Output the full HTML inline, do not write it to a file. Immediately beneath the code block, state plainly that this is prototype-ready, not production-deployable as-is, and name the real build step needed before production (Tailwind CLI, PostCSS, or the hosting framework's build pipeline).
  • Performance Targets: Page load target (<3s), Core Web Vitals targets (LCP, CLS, INP) from the reference file
  • A/B Test Recommendation: What to test, hypothesis, expected impact

Chain with

End by naming what runs next, in one line:

  • ab-test test the new page against the one running now
  • tone-of-voice run this FIRST if you have no voice profile, otherwise the copy is generic

Say it as Next: followed by that skill.

Quality check before returning

Scope of these checks. Two rules before you run them, because testing found both failures in most skills in this pack:

  • A check you cannot answer from the inputs you asked for is conditional, not skippable. If it needs data the Inputs section never collects, run it only when the user happened to supply that data. Otherwise say the check did not run and name the input it needed. Never skip it silently, and never invent the data to make it pass. Inventing is the likelier failure and the worse one.
  • Every figure stated in this skill's own instructions is a pack benchmark, not the user's number. Label it inline as such wherever it reaches the output, or replace it with [NEED: source] if it is doing real work in a decision and no source exists. House rules 4b and 4c have the full version.
  1. Before returning the output, verify:
  • Does the emitted markup meet the accessibility floor: no meaning by colour alone, 4.5:1 text contrast, real labels on every input, visible focus states, semantic landmarks with one h1, and alt text on every image?

  • Does every quantified claim trace to a Proof Points row in the context file, with anything unavailable written as [PROOF NEEDED: <claim>] rather than softened into a vague outcome, and is any internal-only figure kept out of prospect-facing copy?

  • Is the expected traffic source stated, with any target or comparison rate qualified by it rather than by industry alone?

  • Does every quoted rate carry its traffic source, offer type, and what counts as a conversion on this page?

  • Was the field list minimised first, with every remaining field justified as needed before the first human conversation, and enrichment preferred over asking for company, size or industry?

  • Is social proof placed within visual proximity of the form rather than only in the hero or footer?

  • Is the proof specific (a named customer with a number, or a testimonial naming the objection it answers) rather than a decorative logo grid?

  • Is the hero headline under 10 words?

  • Does the FAQ section have 4-5 questions that address the objections the user actually named, not generic FAQs?

  • Are testimonials and logos clearly labeled as placeholders rather than presented as real customer names?

  • Does the section order match the stated page goal (lead capture, product launch, or signup/waitlist), not a default template order?

  • Does the output next to the HTML flag the CDN Tailwind script as prototype-only and name the real build step needed before production?

If any check fails, correct it before returning the output.
