| name | health-model-review |
| description | Audit the portfolio health model — distribution analysis, component weight validation, threshold calibration, signal freshness, and predictive accuracy assessment. Use quarterly or when churn patterns diverge from health classifications. Produces an ops-level health model assessment with calibration recommendations, not account-level health reviews (use the CSM plugin's health-score-review skill for individual accounts; if the `csm` plugin is installed, run `/csm:health-score-review`).

/cs-ops:health-model-review
Audit the health model at the portfolio level — does it actually predict
churn, or does it just classify accounts?
[PROPOSED]
Use when
- Running a quarterly health model calibration review
- Churn patterns are diverging from health classifications — accounts churning
from Green or renewing from Red
- The portfolio's Red-tier percentage has shifted materially and you need to
determine whether it reflects real deterioration or threshold miscalibration
- A component (e.g., usage, NPS, support load) is suspected to have data
coverage gaps that are distorting scores
- Recommending health model threshold changes requires a supporting analysis
Do NOT use for
- Individual account health reviews (use the CSM plugin's health-score-review skill; if the
csm plugin is installed, run /csm:health-score-review)
- Updating health model thresholds in config (use
/cs-ops:customize --section health)
- Pulling the current portfolio health snapshot for a weekly report
(use
/cs-ops:metric-dashboard --weekly for lightweight distribution view)
- Triage of at-risk accounts (use
/cs-ops:segment-analyzer --at-risk)
Typical Activation
/cs-ops:health-model-review — full audit (default)/cs-ops:health-model-review --distribution — portfolio health snapshot only/cs-ops:health-model-review --calibration — predictive accuracy check against churn outcomes/cs-ops:health-model-review --component-audit — component scoring and data coverage review
Pre-flight
Read ~/.claude/plugins/config/claude-for-customer-success/cs-ops/CLAUDE.md
and ~/.claude/plugins/config/claude-for-customer-success/company-profile.md.
If either is missing or contains [PLACEHOLDER] markers, stop and prompt for
/cs-ops:cold-start-interview.
Critical configuration to apply:
- Health model source of truth (CS platform / CRM / manual)
- Components and weights as configured
- Green / Yellow / Red thresholds
- Last calibration date against churn outcomes
- Data quality staleness threshold
G-code dependency: All G-code guardrails referenced in this skill (G1–G9) are defined in the CLAUDE.md config loaded above. If Pre-flight halts or config is missing, G-codes are undefined — do not proceed with partial config.
Reasoning Protocol
Before generating output, apply these primers:
-
CLASSIFY: What type of health model review is this?
- Distribution Anomaly: Portfolio tier distribution is skewed or shifting — ARR concentration in Red/Yellow, sudden migration patterns, or benchmark deviation. Focus on whether the shift is real deterioration or model miscalibration.
- Predictive Accuracy Audit: Health classifications vs. actual renewal outcomes — do Red accounts churn more than Green? Requires historical data. Separate false positives (over-flagging) from false negatives (missing churners).
- Component/Weight Review: Individual component scoring, data coverage, staleness, or weight distribution issues. Critical distinction: zero coverage (data pipeline problem) vs. low scores with full coverage (calibration problem).
- Threshold Recalibration: Explicit request to adjust Green/Yellow/Red boundaries. Must model the cascade — how many accounts and ARR migrate between tiers, and what active CTAs/escalations break.
- Full Audit: Comprehensive review spanning distribution, components, calibration, and recommendations. Default mode — apply all four lenses.
-
CONSTRAINTS: What limits the solution space?
- G1: Health scores are heuristics — calibration findings must not be framed as churn predictions. Decompose into observable component signals.
- G2: Calibration assessment without historical churn data produces a description, not a verdict — surface the data gap explicitly rather than speculating on predictive accuracy.
- G4: Coverage gaps vs. score problems require different corrective actions — never conflate missing data with poor health.
- G5: ARR-at-risk figures must be validated against CRM renewal dates and contract values before sharing with finance or leadership.
- G7: Flag stale data with source date and staleness indicator per configured freshness thresholds.
- Connected integrations limit what can be retrieved — flag gaps, never silently omit.
-
EXPERT CHECK: What would a veteran CS-Ops leader verify first?
- Is the distribution anomaly real deterioration or just threshold miscalibration? Check whether tier shifts correlate with actual churn outcomes before sounding alarms.
- Are component scores being interpreted without checking coverage first? A component at 30% coverage is a data problem, not a health signal — verify coverage before interpreting any average score.
- Before recommending threshold changes, has the cascade been quantified? How many accounts move, how much ARR migrates, and what in-flight escalations break?
-
ANTI-PATTERNS: Common mistakes to avoid:
- Comparing portfolio distribution to industry benchmarks without normalizing by segment — Enterprise and SMB distributions differ structurally.
- Reporting "N accounts churned from Green" without stating what percentage of Green that represents — count without rate is misleading.
- Treating zero-coverage components as zero-score components — missing data is not bad health.
- Recommending threshold changes without listing affected accounts, ARR impact, and active workflows that would break.
- Averaging component scores across segments when segment-level anomalies exist (e.g., Enterprise usage strong, SMB usage collapsing).
- Running a calibration verdict on fewer than 12 months of churn data or fewer than 30 renewal events without flagging the confidence ceiling.
After execution, verify:
- Does the audit answer the real question ("is our health model actually predictive, or just classifying")?
- Are all data sources timestamped and staleness-flagged per G7?
- Is the output mode (--full/--distribution/--calibration/--component-audit) matched to the actual need?
- Confidence: [High] if live integrations + 12mo churn data corroborate / [Medium] if partial data or user-provided exports / [Low] if conversation context only — state which.
Mode
--full: Complete health model audit — distribution, component analysis,
threshold calibration, and recommendations. Default.
--distribution: Portfolio health distribution snapshot only — how many
accounts are in each tier, ARR concentration, and trend vs. prior period.
Lightweight; suitable for weekly leadership reporting.
--calibration: Predictive accuracy assessment — did Red accounts actually
churn at higher rates? Did Green accounts renew? Requires historical data.
--component-audit: Component-by-component scoring review — which components
are driving classification changes, which are stale, which lack data coverage.
Data gathering
Connector error categorization: When a connector call fails, distinguish the error type before proceeding:
- Rate-limited (transient): Connector returns HTTP 429 or equivalent throttle signal. Note the rate limit explicitly in output ("CRM data temporarily rate-limited — retry in 60 seconds recommended") and offer to retry rather than proceeding with degraded output.
- Unavailable (permanent for this session): Connector is not configured, authentication has expired, or service is down. Fall back to the manual-input path below and label all affected sections as "connector unavailable — manual input used."
Do not conflate these — a rate-limited connector will return data shortly; an unavailable connector will not.
Pull from connected integrations:
- CS Platform: health scores, component scores, lifecycle stages, CTA counts
- CRM: ARR by account, renewal dates, churned accounts (last 12 months),
expansion/contraction events, segment classification
If nothing is connected:
"To run a health model review, I need portfolio-level health data.
Share a health score export — one row per account with: account name,
ARR, segment, health score, component scores if available, and renewal date.
I'll run the analysis from what you provide."
Minimum required before proceeding: health classification for each account
(Red/Yellow/Green or numeric score), ARR per account, segment.

Health model source: [configured source] · Data as of: [timestamp]
Portfolio health distribution
| Tier | Accounts | % of book | ARR | % of ARR | Prior period | Change |
|---|
| 🟢 Green | [N] | [%] | $[amount] | [%] | [N] | [↑↓→ N] |
| 🟡 Yellow | [N] | [%] | $[amount] | [%] | [N] | [↑↓→ N] |
| 🔴 Red | [N] | [%] | $[amount] | [%] | [N] | [↑↓→ N] |
| Total | [N] | 100% | $[total ARR] | 100% | | |
ARR at risk (Red + Yellow): $[amount] — [%] of total ARR
Distribution interpretation:
[2-3 sentences on what the distribution signals — not just restating the table.
E.g., "The Red tier concentration in the Enterprise segment represents [%] of
total ARR, which is [above / below / at] the typical 10–15% benchmark for
well-functioning CS organizations. The Yellow-to-Red migration rate of [N] accounts
in [period] warrants investigation into whether Yellow thresholds are correctly
calibrated or whether recovery plays are failing to prevent deterioration."]
Distribution flags
Automated checks against the configured model:
| Check | Status | Detail |
|---|
| Red ARR > 20% of total | [⚠️ Flag / ✅ OK] | [Red ARR is [%] of total] |
| Green-tier accounts with upcoming renewal (<90 days) | [N accounts / [%] of Green] | [Names or count] |
| Red-tier accounts without an active CTA or play | [N accounts / $ARR] | [Data gap — accounts at risk with no assigned action] |
| Health scores not updated in >[configured threshold] days | [N accounts] | [Stale data risk] |
| Accounts with no health score assigned | [N accounts / $ARR] | [Coverage gap] |
Component analysis (--component-audit content)
For each configured health component:
| Component | Weight | Avg score (Green) | Avg score (Yellow) | Avg score (Red) | Data coverage | Staleness |
|---|
| [Component 1, e.g., Usage] | [40%] | [score] | [score] | [score] | [%] of accounts have data | [% updated in threshold window] |
| [Component 2, e.g., Engagement] | [20%] | | | | | |
| [Component 3, e.g., Support load] | [20%] | | | | | |
| [Component 4, e.g., NPS] | [20%] | | | | | |
Component interpretation:
For each component where anomalies exist:
[Component name] — [flag type]:
[What the anomaly is, what it might mean, what action it implies]
Example: "Usage is weighted at 40% but has only 67% data coverage — meaning
33% of accounts receive a health score with usage defaulted to zero or averaged
from available data. This artificially depresses scores for accounts where
product instrumentation is incomplete, not where usage is actually low.
Recommend: resolve instrumentation gaps before the next health model calibration,
or weight usage conditionally by segment." [review]
Threshold calibration assessment (--calibration content)
Requires historical churn data (last 12 months minimum).
Predictive validity check:
| Health tier at 90 days pre-renewal | Churned | Renewed | Expanded | Predictive accuracy |
|---|
| 🔴 Red | [N] ([%]) | [N] ([%]) | [N] ([%]) | [Red → churn rate] |
| 🟡 Yellow | [N] ([%]) | [N] ([%]) | [N] ([%]) | [Yellow → churn rate] |
| 🟢 Green | [N] ([%]) | [N] ([%]) | [N] ([%]) | [Green → churn rate] |
Calibration verdict:
| Finding | Detail |
|---|
| Red accounts that renewed | [N] — false positives driving unnecessary escalation |
| Green accounts that churned | [N] — false negatives that bypassed churn intervention |
| Predictive accuracy score | [Red churn rate − Green churn rate] — [interpretation] |
Calibration interpretation:
[2-3 sentences on whether the health model is predictive. Name the primary failure
mode: false positives (over-flagging healthy accounts) or false negatives
(missing accounts that churn). Recommend threshold adjustment if warranted.]
If historical data is not available:
"Calibration assessment requires historical churn data (which accounts churned,
their health classification at 90 days pre-renewal). This data was not available
from connected sources. Recommend running the calibration assessment manually:
pull churned accounts from the last 12 months, join to their health scores at
90-day pre-renewal, and compare classification to outcome." [review]
Health model recommendations
Ranked by impact. Specific and actionable — not generic.
Priority 1 — [Recommendation headline]:
[What to change, why, what outcome to expect. Reference specific data from
the audit above. Example: "Reduce the Green threshold from >70 to >75 — [N]
accounts currently classified Green would move to Yellow, better reflecting
the [%] of accounts in the 70-75 range that churned in the last 12 months."]
Priority 2 — [Recommendation headline]:
[...]
Priority 3 — [Recommendation headline]:
[...]
If no changes are warranted:
"The health model is performing within expected parameters. No calibration
changes are recommended at this time. Schedule next review for [date — per
configured review cadence]."

Output
Health model audit report — format driven by the mode flag
(--full, --distribution, --calibration, or --component-audit).
Produces a structured markdown report with: scoring signal inventory, weight
justifications, threshold analysis, benchmark comparison, and recommended changes.
See Full health model audit section for field-level detail.
Guardrails
Health scores are heuristics. The health model review identifies
calibration issues; it does not override individual CSM judgment on
specific accounts. Component anomalies are audit findings, not
directives.
Calibration requires historical data. A calibration assessment
without churn outcome data produces a description, not a verdict.
Surface the data gap explicitly rather than speculating on predictive
accuracy.
Threshold changes affect active escalations. Before recommending
threshold changes, note that accounts currently in Red may move to Yellow
(or vice versa), affecting active CTAs and escalation routing. Recommend
a transition plan alongside any threshold change.
Coverage gaps vs. score problems. Distinguish between a component
that is scoring poorly and a component that has no data. A zero-coverage
component is a data pipeline problem; a poorly-scoring component with
full coverage is a calibration problem. The corrective action differs.
No revenue implications without validation. ARR-at-risk figures from
the distribution must be validated against CRM renewal dates and contract
values before sharing with finance or leadership.
