What it does

Retention Analysis is an agent skill from mohitagw15856/pm-claude-skills. Structure a retention analysis, churn investigation, or engagement deep-dive for any product team. Use when asked to analyse user retention, investigate churn, measure DAU/MAU, or build a retention improvement plan. Produces a retention snapshot with root cause hypotheses, aha-moment correlation, and prioritised interventions.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/curve-reading.md`, `references/worked-example.md` and `templates/retention-readout.md`).

It sits in Data & Analytics, covering Product analytics. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked to analyse user retention
  • Investigate churn
  • Measure DAU/MAU
  • Build a retention improvement plan

Example prompts

  • “/retention-analysis”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Segment the problem
  2. Find the inflection points
  3. Identify the "aha moment" correlation
  4. Qualify the churn

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Retention Analysis loads about 1.9k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 929 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Structure a retention analysis, churn investigation, or engagement deep-dive for any product team. Use when asked to analyse user retention, investigate churn, measure DAU/MAU, or build a retention improvement plan. Produces a retention snapshot with root cause hypotheses, aha-moment correlation, and prioritised interventions.

Retention Analysis Skill

Diagnose why users leave, identify what keeps them, and recommend specific, testable interventions — not vague "improve onboarding" suggestions.

Retention Fundamentals

The retention curve has two components:

  1. Steepness of initial drop (D1–D7) — onboarding problem
  2. Long-term floor level — product-market fit indicator

A product with PMF has a retention curve that flattens. If it trends to zero, you have a PMF problem, not an onboarding problem. Name this distinction explicitly.


Retention Metrics Definitions

MetricFormulaWhat It Tells You
D1 RetentionUsers who return on day 2 ÷ new users day 1Quality of first experience
D7 RetentionUsers active on day 8 ÷ users who joined 7 days agoEarly habit formation
D30 RetentionUsers active on day 31 ÷ users who joined 30 days agoProduct-market fit signal
DAU/MAU RatioDaily active users ÷ monthly active usersStickiness (>20% good, >50% excellent)
Churn RateUsers lost in period ÷ users at start of periodMonthly or annual
Net Revenue RetentionMRR at end of period ÷ MRR at start (same cohort)Revenue health including expansion

Retention Investigation Framework

Step 1: Segment the problem

Don't analyse "retention" — analyse retention for specific cohorts:

  • New vs returning users
  • Paid vs free
  • Acquisition channel (organic vs paid vs referral)
  • Onboarding path completed vs not
  • Feature usage (power users vs lurkers)
Step 2: Find the inflection points

Where does the drop happen? D1? D7? Month 3?

  • D1 drop → First session experience
  • D7 drop → Habit loop not formed
  • D30 drop → Value not delivered at depth
  • Month 3+ drop → Boredom, competition, or lifecycle event
Step 3: Identify the "aha moment" correlation

Which early behaviour predicts long-term retention?

  • Run correlation: users who did [X] in first 7 days vs 30-day retention
  • Common patterns: connected an integration, invited a teammate, completed a core action N times
Step 4: Qualify the churn

Interview churned users — never skip this. Survey data alone is insufficient.

  • "What was the trigger that led you to cancel/stop?"
  • "What were you trying to accomplish that you couldn't?"
  • "What would need to change for you to come back?"

Required Inputs

Ask the user for these if not provided:

  • Product and business model (SaaS / consumer app / marketplace / other)
  • Current retention metrics (D1, D7, D30 if available)
  • Segment to analyse (all users / paid / free / a specific cohort)
  • Key question to answer (why is retention dropping? what drives retention?)
  • Available data (analytics events, churn surveys, interview notes)

Deeper Materials

This skill ships with support files — use them when they are available:

  • references/curve-reading.md — Reading Retention Curves Without Fooling Yourself. Apply it while producing the output; it carries the calibration and judgment calls the method summary above compresses.
  • templates/retention-readout.md — a fill-in version of the deliverable with the quality gates inline. Offer it when the user wants to work the document themselves rather than have it generated.

Curve diagnosisReports a retention number without curve shapeShape shown but not interpretedFlattening vs trending-to-zero explicitly diagnosed and tied to what it means (PMF vs onboarding problem)

Intervention specificity"Improve onboarding"-grade adviceSpecific actions but no measurement planInterventions name the user moment they target, plus a monitoring plan with an alert threshold and churned-user interviews

Quality Checks

  • Retention curve shape is diagnosed (flattening vs trending to zero = PMF vs onboarding)
  • Cohorts are segmented before analysis (not all users lumped together)
  • "Aha moment" correlation is identified or flagged as unknown
  • Interventions are specific (not "improve onboarding")
  • Churned user interviews are recommended (not just data analysis)
  • Monitoring plan includes an alert threshold

Anti-Patterns

  • Do not recommend "improve onboarding" without specifying what specific step to change and why
  • Do not analyse retention without segmenting by cohort — aggregate retention curves hide cohort-specific patterns
  • Do not treat DAU/MAU below 5% as a retention problem — at that level, it is a product-market fit problem
  • Do not skip qualitative research — churned user interviews reveal reasons that quantitative data cannot
  • Do not set a monitoring alert without specifying the threshold that triggers it

Guidelines

  • Never recommend "improve onboarding" without specifying what to change and why
  • Benchmark against industry — consumer apps, SaaS, and marketplaces have very different retention norms
  • If DAU/MAU is below 5%, that's a PMF conversation, not a retention tactics conversation
  • Always recommend talking to churned users — no amount of data replaces understanding the reason

Example Trigger Phrases

  • "Analyse user retention."
  • "Investigate churn."
  • "Build a retention improvement plan."
