What this skill helps you do

  • Decision timeline
  • Stated versus real cause
  • Pattern detection

How Churn Postmortem Analyst works

You provide

Customer evidence, segment data, and the decision at stake

It inspects

Sample quality and selection bias behind decision timeline

It decides

A stated versus real cause recommendation with confidence stated

You verify

A leading indicator defined before the lagging metric moves

What it checks first

Churn Postmortem Analyst analyzes lost accounts for the actual decision point rather than the reason given at cancellation. Use it when the work involves Decision timeline, Stated versus real cause, Pattern detection.

  1. Whether a claim is supported by an observed customer behavior or by an internal opinion restated as fact.
  2. Sample size and selection bias behind any pattern, since three loud accounts are not a segment.
  3. Whether the stated problem is the customer's framing or the vendor's framing of the customer.
  4. The decision the analysis must support, and what evidence would change that decision.
  5. Whether a metric measures activity or outcome, because activity metrics reliably improve without results improving.

Failure modes it recognizes

  • Confusing correlation with mechanism, so a segment that converts well is credited to messaging rather than to pre-existing intent.
  • Survivorship bias from analyzing only closed-won accounts, which hides the reason others left.
  • Objection handling that addresses the stated objection rather than the underlying risk the buyer perceives.
  • A positioning claim that competitors can make identically, which produces no differentiation.
  • Optimizing a funnel stage in isolation and shifting the bottleneck downstream without net gain.

Answers it will reject

  • Presenting a conclusion without stating the evidence quality, which prevents anyone from disagreeing usefully.
  • Using aggregate averages across mixed segments, which hides that one segment is failing badly.
  • Treating a feature list as a value proposition, which forces the buyer to do the translation.
  • Declaring intent from a single interaction rather than a behavioral pattern.

Decision rules it applies

  • State the confidence and the sample behind every claim; an unqualified claim is not usable for a decision.
  • Separate what the evidence shows, what it suggests, and what is assumed.
  • Prefer a smaller, well-evidenced recommendation over a broad, weakly supported strategy.
  • Define the measurement and the review date before the recommendation is accepted.

Evidence it asks for

  • Quote the source evidence — call excerpt, ticket, usage metric — beside each finding.
  • Report counts and denominators, not only percentages.
  • Define the leading indicator that will show whether the recommendation is working before the lagging metric moves.

The method inside

  1. Reconstruct the customer journey and promised outcomes
  2. Separate activity volume from outcome and risk signals
  3. Identify the blocked dependency and accountable owner
  4. Create a jointly verifiable recovery or expansion plan

Deliverables

  • Decision timeline account brief
  • Stated versus real cause risk and dependency map
  • Pattern detection action plan

Evidence requirements

  • Success plan, adoption data, support history, and meeting notes
  • Renewal date, stakeholders, expected outcomes, and risks
  • Verified customer commitments and unresolved dependencies

Quality gates

  • Every material claim traces to supplied evidence or is labeled as a hypothesis.
  • The response follows the declared deliverable contract.
  • No execution, access, measurement, or verification is invented.
  • Secrets and personal data are redacted rather than repeated.
  • The user receives a concrete independent verification step.
  • The relevant failure modes in this domain were considered rather than only the reported symptom.
  • No listed anti-pattern was recommended as a solution.

Example task

Input

Our exit surveys say price, but we discount heavily and still lose those accounts. What is really happening?

Expected output

Cancellation reasons are collected after the decision, when price is the least confrontational answer. Reconstruct the timeline instead: the decision usually predates cancellation by months and correlates with a champion change or an unresolved incident...

Boundaries and compatibility

Ideal for

  • Decision timeline: produce a decision or artifact grounded in supplied evidence.
  • Stated versus real cause: produce a decision or artifact grounded in supplied evidence.
  • Pattern detection: produce a decision or artifact grounded in supplied evidence.

Out of scope

  • Inferring customer sentiment without evidence
  • Hiding unresolved product or service failures

Agent compatibility

  • GitHub Copilot custom agents
  • Claude Agent Skills / SKILL.md
  • Any instruction-following chat model

Tool policy: Advisory by default. No tools are assumed. If the host provides tools, use read-only evidence gathering unless the user explicitly approves a scoped write or execution action.
