name: product-health-analysis description: "Interpret product metrics against goals and surface actionable signals. Use when asked to analyse product health, review key metrics, investigate a performance issue, produce a health report, or assess product-market fit signals. Produces a structured health report with RAG status, trend analysis, root cause hypotheses, and prioritised actions."

Product Health Analysis Skill

Transform raw metrics data into a clear health narrative — what's working, what's not, and what needs immediate attention.

Required Inputs

Work from what is given. If any of these is missing, still produce the complete output: fill each gap with a reasonable assumption marked (assumed, confirm) and list those assumptions at the end. Ask a question first only when the core subject itself is missing (there is nothing to write about).

• Metrics data (current values for key metrics — even rough numbers work)
• Targets or benchmarks (OKR targets, historical baselines, or industry benchmarks)
• Period (week / month / quarter being analysed)
• Product area or segment (are we looking at the whole product or a specific feature?)

Metrics Framework

Analyse across four layers:

1. Acquisition — new users, source quality, CAC trends
2. Activation — time to first value, onboarding completion rates
3. Engagement — DAU/MAU, feature adoption, session depth
4. Retention — D1/D7/D30 retention, churn rate, resurrection rate

Process

1. For each metric, compare: current period vs. previous period, current vs. target
2. Flag anything more than 10% off target as requiring investigation
3. Look for correlations — does a drop in activation explain a retention dip 2 weeks later?
4. Write a plain-English health summary (no jargon) suitable for sharing with non-data stakeholders
5. Recommend top 3 areas for immediate investigation with suggested diagnostic steps
6. Validate — Confirm every flagged metric has a plausible root cause hypothesis, not just a raw number, and every recommended action has a specific owner or team

Output Structure

Product Health Report — [Period]

Overall Health: 🟢 On Track / 🟡 Watch / 🔴 Action Required

Metric	Current	Target	vs. Last Period	Status
[metric]	[value]	[target]	[+/-%]	[🟢/🟡/🔴]

Key Observations: [3-5 bullet observations written in plain English]

Areas Requiring Investigation:

1. [Metric + hypothesis + suggested diagnostic]
2. [Metric + hypothesis + suggested diagnostic]
3. [Metric + hypothesis + suggested diagnostic]

Recommended Actions: [Specific next steps with owners and timelines]

Deeper Materials

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

• references/signal-vs-noise.md — Product Health: Separating Signal from Dashboard Noise. Apply it while producing the output; it carries the calibration and judgment calls the method summary above compresses.
• templates/health-review.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.

Dimension	0	5	10
Target & trend discipline	Metrics shown as bare snapshots; no targets or period-over-period comparison	Most metrics have targets and trends, but some RAG statuses don't follow from the numbers or targets are accepted uncritically	Every metric has target, trend, and a status that follows from both — and at least one target is itself challenged if it's no longer meaningful
Root cause depth	Movements listed without explanation ("activation dropped 27pts")	Flagged metrics have hypotheses, but they're generic ("onboarding friction") with no diagnostic to confirm them	Every flagged metric has a specific, falsifiable hypothesis plus a named diagnostic step, and at least one cross-metric correlation (e.g. activation → retention lag) is drawn
Segment honesty	Only blended aggregates reported; opposing segment trends invisible	Some segment cuts shown, but the headline observations still lean on averages that hide divergence	Every material aggregate is decomposed where segments diverge, and the divergence itself is surfaced as a finding, not a footnote
Verdict & actionability	No overall rating, or a rating asserted without evidence; actions missing or ownerless	Overall RAG present and roughly justified; actions exist but some lack owners, dates, or a link to a flagged metric	Overall rating argued from specific evidence (including against the good news), and every action has a named owner, a date, and traces to an investigation or observation

Quality Checks

• Every metric includes both a target and a trend (not just a snapshot)
• At least one correlation is drawn between metrics (e.g., activation → retention)
• Every flagged metric has a root cause hypothesis, not just "it dropped"
• Observations are written for a non-technical stakeholder (no raw query language or data jargon)
• Overall health rating is justified with specific evidence

Anti-Patterns

• Do not report a single aggregate metric without segment breakdowns — averages hide opposing trends
• Do not flag a metric as healthy just because it is above the target — check if the target itself is meaningful
• Do not list metric movements without root cause hypotheses — observations without explanations are not analysis
• Do not mix product health metrics with business KPIs without explaining the relationship between them
• Do not omit recommended actions — a health report that only describes problems without prioritised next steps is incomplete

Example Trigger Phrases

• "Analyse product health."
• "Review key metrics."
• "Investigate a performance issue."
• "Produce a health report."
• "Assess product-market fit signals."
