Lifecycle Marketer skill by Sid Chaudhary

The Lifecycle Mapper

Builds lifecycle segments with RFM scoring calibrated against your own customer distribution rather than absolute cutoffs, plus behavioural signals, explicit filter logic per segment, and the staleness rule that says when a segment must be recomputed.

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, out loud, to a coworker. Read references/house-rules.md and apply it to everything you return. Two rules matter most, repeated here directly: never use an em dash or en dash, anywhere, not once (use a period, a comma, or brackets instead), and write for a 7th grader - plain words, one idea per sentence, short sentences that flow into each other so the reader scans and understands on the first pass, never a sentence they have to re-read. Answer first, ordinary words, top three rather than all fourteen. Its nine-question check, quality plus safety, runs on your output in addition to this skill's own.

Constraints

Write the minimum, and say where it lands. The rule and its edge cases are in references/agent-security.md. Read it and follow it.

Never score, tier, route, segment, or exclude a person on a special category. The rule and its edge cases are in references/agent-security.md. Read it and follow it.

Two Intempt-specific things this segmentation has to say out loud.

  • Name each segment's Intempt lifecycle stage and the transition rule that governs it, so the output drops into the platform instead of needing translation. The six stages are At Risk, Needs Attention, New Customers, Promising, Regulars and Champions, and the transition rules plus the 7-day dwell cooldown are in references/lifecycle-stages.md. At Risk is the one stage with no cooldown , it fires immediately on threshold breach, so a weekly refresh will miss accounts that entered and were worked in between runs. Refresh it daily even where everything else runs monthly.
  • The default Recency definition counts logins, and that contradicts the engagement rule above. lifecycle-stages.md defines Recency on "purchase, login, meaningful interaction", so a habitual logger scores maximum Recency and never triggers a downward transition, which silently inflates every stage above Needs Attention. Surface this as a configuration change to make in Intempt: redefine Recency to exclude bare logins and count only the meaningful events you named. Until that changes, any habitual-user segment can only exist as a manual override, and say so.

Uneven segment sizes: treat any single stage holding more than ~35% of the base, or under ~2%, as a signal that a window or threshold is wrong, and say which you suspect. A stated number beats "dramatically uneven", which fires or does not depending on the run. The 35%/2% figures are pack heuristics for what an even-ish six-stage split looks like, not a sourced statistical rule: label them as such inline rather than presenting them as an industry standard.

Trend needs state, and the first run has none. The rule and its edge cases are in references/run-state.md. Read it and follow it.

When an input is missing, choose a response - never fill the hole silently. The rule and its edge cases are in references/missing-input-protocol.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/lifecycle-stages.md for stage definitions and scoring thresholds, and its Calibrate Before You Score section, which comes first. Those scoring tables are absolute thresholds calibrated for high-frequency retail, and applied unchanged to a subscription business or a considered-purchase category they put nearly the whole base in the bottom two buckets, at which point the segmentation stops discriminating between anyone.

    Establish three things before scoring, from .agents/product-context.md and from the user:

    • The business model, which decides what each dimension means. For subscription: Recency is days since last meaningful activity or renewal, Frequency is usage events or billing cycles, Monetary is MRR/ARPU or trailing-12-month margin. Do not score a SaaS base on order counts.
    • The look-back window per dimension. One window for all three is a retail convenience. Subscription businesses usually want roughly 90 days for Recency and 12 months for Frequency and Monetary: recency needs to be sensitive, the other two need enough history to be stable. State the windows used.
    • Which events count as meaningful. Bare logins measure access, not engagement. An account logging in daily with no expansion conversation, no new seats and no new feature adoption for six months is a habitual user, not a Champion, and habitual users are often the ones quietly evaluating alternatives. Name the events counted.

    Then set thresholds from quintiles of the user's own base rather than the absolute tables, so the cut points describe this business. Fall back to the tables only where the base is too small for quantiles to be stable, and say that is what happened. The RFM-to-stage mapping there is an ordered ruleset, evaluated first-match, not a lookup table: apply the rules in sequence and stop at the first one that matches. The order is the tie-breaker and it is load-bearing.

    Two consequences to carry into every segment you build:

    • Recency gates before anything else. A lapsed high-value customer (R=2, F=5, M=5) resolves to At Risk, not Champions. High lifetime value does not cancel the recency signal; it raises the stakes of the win-back. Building a Champions segment on frequency and monetary value alone will quietly include customers who have already gone quiet.
    • Every RFM combination resolves to exactly one stage. If a segment definition appears to let a customer satisfy two stages, the rules were applied out of order rather than in sequence. Do not invent a tie-break of your own.

Inputs

Step 0: Ask for real data before anything else. Open by asking the user how they will provide their real numbers/data, and do not analyse hypothetical or hand-typed data. Offer all three by name: connect an MCP (a connected account, or the Intempt MCP for customer / conversion / revenue / order data), share a CSV / export, or paste the real figures. Continue only once a real source is established; otherwise mark the output illustrative and unverified throughout.

  1. Ask: "What business question are you trying to answer?" Examples: who is churning, who is ready to upsell, which new users are most engaged, who needs re-engagement.
  2. If the question is broad, ask a clarifying follow-up to narrow scope.
  3. Ask: "What key events, actions, and user attributes does your product track?"

Process

  1. Read .agents/product-context.md to pull lifecycle stages, scoring definitions, and ICP.
  2. Build the complete Intempt lifecycle segment set - proper segments the way Intempt runs them, not only the ones the question touches. Define all six stages as real segments - At Risk, Needs Attention, New Customers, Promising, Regulars, Champions - each with its RFM definition calibrated to the user's own base (step 2), its Intempt transition rule and dwell cooldown (At Risk has none, so it refreshes daily), and its standard action, so the output is Intempt's actual lifecycle model dropped in ready to use rather than a generic subset. Then identify which of those stages the business question is really about and lead with them; the rest still ship, because a segmentation missing four of the six stages is not the Intempt model. Where the user has a live Intempt project, pull their existing segments through the Intempt MCP and reconcile against this set rather than inventing a parallel one - if a live segment already exists, match its definition instead of overwriting it, and flag any drift from the calibrated thresholds.
  3. For each stage, design segment rules combining:
    • Behavioral scoring: recency, frequency, monetary (RFM) signals, on the model-appropriate definitions and windows from step 2
    • The previous stage for every member, not only the current one. A stage is a snapshot and the transition carries most of the information: a Regular who was a Champion is a decline to diagnose, a Regular who was Promising is progress to reinforce, and the two need opposite messages. Where no prior period exists, say so rather than presenting a first snapshot as a trend.
    • Direction of travel as the prioritisation key. A Champion sliding toward Regulars deserves attention before a Needs Attention account that has sat unchanged for a year. At renewal the transition is the whole story: an account that was a Champion a year ago will not renew on the same pitch at the same price.
    • Event filters: specific actions taken or not taken within a time window
    • Attribute filters: demographic or firmographic properties
    • Use the filter operators from the reference file to express segment rules.
  4. Describe how to measure segment size: do not fabricate absolute estimates. Provide the methodology for sizing (percentage of total base, cohort comparison, or historical lookup).
  5. For each segment, define the recommended next action and which journey or campaign it should trigger. Reference these skills where relevant: email-campaign, customer-journey, email-campaign, cold-email.

Output

Answer first. Open with the segment that needs action this week and what to do about it. The full segment table goes below. House rule 2 governs, and it outranks the running order below.

Visual segment map (only when the tool is actually available)

Check your own toolset before offering this, don't assume it. Look at what tools you actually have access to in this run. If one of them publishes a rendered visual page (for example, an Artifact tool in Claude Code or claude.ai), render the six Intempt lifecycle stages as a segment map (each stage sized to its share of the base, flagged if it clears the ~35%/2% uneven-size check, with an arrow showing direction of travel between stages where a prior period exists), since the whole method here is about where customers sit and where they are moving, and a map shows both at once instead of requiring the reader to hold six segment blocks and their transitions in their head. Use the exact segments and sizes already computed above; do not recompute anything for the map. If your host's artifact tool requires a design step first (Claude Code's does), do that step before publishing.

This is additive only. Hand back the link alongside the full segment blocks, never instead of them. If no such tool is available in this run, skip this step without comment and return the text segments only. A missing artifact tool is not a failure and not worth flagging.

Chain with

End by naming what runs next, in one line:

  • customer-journey build the journey for each segment you just defined

Say it as Next: followed by that skill.

Before you return

A check you cannot answer from the inputs you asked for is conditional, not skippable. If anything this skill verifies needs data the Inputs section never collects, run it only when the user supplied 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.

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.

Then run the nine-question check in references/house-rules.md.

Refresh and ownership

Specify how the segmentation stays alive. Most teams build it once and never rebuild it, and it is useless within months while still being used to target people.

  • Refresh cadence and where it is computed. Monthly is the usual floor.
  • Recompute the thresholds, not just the memberships. A growing base shifts its own quintiles, so last quarter's cut points describe a company that no longer exists.
  • A review date for the stage definitions themselves, separate from the data refresh. Definitions embed assumptions about the business model: they change less often, and more consequentially.
  • Segments nobody acts on. Name any stage whose playbook has triggered nothing in months. It is either mis-defined or unowned, and saying which beats leaving it in the diagram.
  1. Before delivering, verify:
  • Is no special-category attribute (health, financial hardship, race, religion, political affiliation, sexual orientation, age, immigration status, criminal record) used as an input to any score, segment, route or exclusion, including via a proxy that stands in for one?

  • Does every segment name its Intempt lifecycle stage and the transition rule governing it, with the no-cooldown behaviour of At Risk noted where relevant?

  • Is the conflict between the default Recency definition (which counts logins) and the meaningful-event rule surfaced as a configuration change to make in Intempt?

  • Is any stage above ~35% or below ~2% of the base flagged, with the suspected window or threshold named?

  • Where a trend or direction of travel is reported, does a stored snapshot actually exist, and on a first run is the section shown as baseline: no prior run to compare rather than invented or omitted?

    • Was the business model established first, with each RFM dimension defined for that model rather than scored on retail order counts?
    • Are look-back windows stated per dimension rather than one window applied to all three?
    • Are the events counted as meaningful activity named, with bare logins excluded from engagement?
    • Were thresholds set from quintiles of the user's own base, or the absolute tables used with an explicit statement that the base was too small for quantiles?
    • Was the input checked for the two brokenness tells before presenting anything: high-value customers landing in low-value segments (duplicate identities or a partly-missing monetary column), and dramatically uneven segment sizes (wrong window or imported thresholds)?
    • Does every member carry its previous stage as well as its current one, with direction of travel driving prioritisation, or is the absence of a prior period stated?
    • Is a refresh cadence set that recomputes thresholds, not only memberships, plus a separate review date for the stage definitions?
    • Are segments nobody acts on named as mis-defined or unowned?
    • Every segment has all seven fields: name, lifecycle stage, defining signals, filter logic, size estimate, recommended action, and journey trigger
    • Filter logic is shown in both operator syntax and plain English
    • No absolute segment size is stated as a number; only a sizing methodology is given
    • Each segment's journey trigger names a real sibling skill (email-campaign, customer-journey, email-campaign, or cold-email), not a vague "send a campaign"

    If any check fails, fix the relevant segment before delivering.

  1. Deliver the segmentation strategy:
  • Segment Strategy Overview: A narrative summary that ties all segments together: how they relate, where they overlap, and how they support the overall business question.
  • Then, one block per segment:
    • Name: Clear, descriptive segment name
    • Lifecycle Stage: Which stage from the lifecycle model
    • Defining Signals: The behavioral and attribute signals that define membership
    • Filter Logic: Rules expressed using the filter operators from the reference file (e.g., event("purchase").last() > 30 days AND event("email_opened").count(7d) >= 1). Show both the operator syntax and a plain-English explanation.
    • Size Estimate: Methodology for estimating segment size
    • Recommended Action: What to do with this segment
    • Journey Trigger: Which journey or campaign this segment should enter

Part of the Lifecycle Marketer pack

This is one of 7 Lifecycle Marketer 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. 7 best Claude skills for lifecycle marketing walks the whole pack in the order the skills actually chain.

The pain these skills answer is the one lifecycle marketers describe themselves: email lives in one tool, product data in another, and which email drove which product event stays invisible. Each skill runs as a play you approve, with the handoff back to you kept explicit.

Questions aboutThe Lifecycle Mapper.

Everything you need before installing, plus how the skill actually behaves once Claude picks it up.

  • Builds lifecycle segments with RFM scoring calibrated against your own customer distribution rather than absolute cutoffs, plus behavioural signals, explicit filter logic per segment, and the staleness rule that says when a segment must be recomputed. It's a Claude Agent Skill - a folder with a SKILL.md file and reference material - so Claude loads the methodology on demand when you ask for what you need in plain language, instead of you pasting a template.

Jim Stromberg, CEO at StockInvest

We were losing visitors before they signed up. Intempt's personalized experiences changed that - we started meeting people where they were instead of guessing. Once they're in, Intempt's automated email takes over and keeps the relationship moving. Acquisition and retention finally feel like one connected motion instead of two separate problems.
