About

What it does

Personalization rules mapping audience segments to content variants, with a measurement plan.

You'll know it's time when...

Content is reading generic to every audience, and personalization rules aren't tied to a measurable outcome.

How it works

Experimentation Lead skill by Sid Chaudhary

Context

  1. Check for .agents/product-context.md: if missing, ask the user to run /gtm:product-context first. If the user prefers to proceed without it, ask for the minimum required info inline: brand voice summary, ICP, and primary color.
  2. Read references/personalization-rules.md for rule syntax, zone types, and priority logic.

Inputs

  1. Ask: "What page or touchpoint do you want to personalize?" (homepage, pricing page, email content, in-app banner, product page)
  2. Ask: "Which segments matter most?" If the user is unsure, recommend segments based on the lifecycle model from product context.
  3. Ask: "Describe the current (default) experience on this touchpoint."

Process

  1. Read .agents/product-context.md to pull lifecycle stages, ICP, scoring definitions, and brand voice.
  2. For each target segment, design a personalization rule:
    • Condition: The audience filter that triggers this variant (lifecycle stage, behavioral signal, attribute, or combination)
    • Zone: Where on the page/touchpoint the content changes (hero, CTA, banner, sidebar, etc.)
    • Type: Specify the type of personalization: content swap, layout change, offer variant, navigation change, or CTA change. Refer to the personalization types in the reference file.
    • Experience: What the visitor sees: copy variant, image direction, CTA text and destination
  3. Order rules by priority. Use the priority numbering system from the reference file (1-10 for critical overrides, 11-30 for high-value segments, etc.).
  4. Define the default experience: what visitors see when no rule matches.
  5. Design the measurement plan:
    • Run an A/B test: personalized experience vs. default for each segment
    • Primary metric tied to the touchpoint goal (e.g., click-through for CTA, signup for landing page)
    • Use the measurement guidance from the reference file, including minimum sample sizes (200 impressions per variant) and statistical significance requirements.
    • Provide a framework for evaluating whether the personalization is working.
  6. Flag any conflicts or overlapping conditions between rules. When conflicts are found, recommend resolution: merge overlapping rules, reorder by priority, or suggest mutually exclusive conditions.
  7. Recommend a progressive personalization roadmap using the maturity path from the reference file (anonymous → known → deep → maturity).
  8. If the touchpoint involves product or content recommendations, design a recommendation approach using the algorithms from the reference file.

Output

  1. Before delivering, verify:
  • Every rule has all five fields: condition, zone, type, experience, and metric
  • Rules are ordered using the reference file's priority numbering (1-10 critical, 11-30 high-value), not an arbitrary order
  • A default experience is defined for non-matched visitors
  • Any overlapping or conflicting conditions between rules are flagged with a resolution, not left unresolved
  • The measurement plan states a minimum sample size and a primary metric, not just "run an A/B test"
  • Every condition's behavioral signal or attribute traces to a segment definition the user actually gave, or to the lifecycle stages and scoring definitions in product context, with no invented customer detail, firmographic fact, or behavioral signal presented as something the user's data already shows. If a needed attribute isn't confirmed, flag it as an assumption to verify against the user's real data.

If any check fails, fix the relevant rule or section before delivering.

  1. Deliver the personalization strategy:
  • Rules: In priority order, one block per rule:
    • Priority: Rule evaluation order (1 = highest)
    • Condition: Audience filter in human-readable form
    • Type: Personalization type (content swap, layout change, offer variant, navigation change, or CTA change)
    • Zone: Where the content changes
    • Experience: Copy, image direction, CTA for this variant
    • Metric: How success is measured for this rule
  • Default Experience: What all non-matched visitors see
  • Measurement Plan: A/B test design: personalized vs. default, primary metric, evaluation framework, duration estimate
  • Personalization Roadmap: Progressive maturity path from anonymous to deep personalization
  • Recommendations: Recommendation approach (if applicable)

Part of the Experimentation Lead pack

This is one of 10 Experimentation Lead skills. They chain - the order you run them in changes what you get, and running one in isolation usually means re-answering setup another skill already captured. 10 best Claude skills for CRO and A/B testing walks the whole pack in the order the skills actually chain.

Install

Two ways to run it.

Pick your Claude surface. Both paths take under a minute.

Prefer one command? npx skills add sidchaudhary/gtm-skills installs the whole set via the community skills CLI. If you'd rather not run a third-party CLI, use either path below to install the ZIP directly.
