openclaw skills install data-ground-truthWhen presenting numbers, metrics, or statistics in reports, recommendations, or analysis — verify the facts and contextualize the figures against industry baselines. Combines verify (live fact-checking) with norm (statistical benchmarking).
Use this skill when:
Do NOT use for: opinions, qualitative assessments, or metrics with no established baseline.
Determine whether each number is:
For current facts (prices, rates, dates), use verify-claim.
MCP (preferred): verify_claim({ claim: "The USD to EUR exchange rate is 0.92" })
HTTP:
curl -X POST https://verify.agentutil.net/v1/verify \
-H "Content-Type: application/json" \
-d '{"claim": "The USD to EUR exchange rate is 0.92"}'
Handle verdicts per the verify-claim decision tree (confirmed → use, stale → update, disputed → present both sides, false → correct).
For business metrics, check where the value falls on the distribution.
MCP (preferred): norm_check({ category: "saas:churn_rate_monthly", value: 5.2, unit: "%" })
HTTP:
curl -X POST https://norm.agentutil.net/v1/check \
-H "Content-Type: application/json" \
-d '{"category": "saas:churn_rate_monthly", "value": 5.2, "unit": "%"}'
For multiple metrics at once:
curl -X POST https://norm.agentutil.net/v1/batch \
-H "Content-Type: application/json" \
-d '{"items": [{"category": "saas:churn_rate_monthly", "value": 5.2}, {"category": "saas:nps_score", "value": 45}]}'
Optional: add company_size (startup/smb/mid_market/enterprise) and region for more specific baselines.
When reporting findings, combine verification and benchmarking:
| Data type | How to present |
|---|---|
| Verified fact | "The current [metric] is [current_truth] (verified live, [freshness])." |
| Benchmarked metric | "[Value] is at the [percentile]th percentile — [assessment] for [category]." |
| Both | "At [current_truth] (verified), this is [percentile]th percentile vs. industry ([baseline source])." |
| Anomalous metric | Flag clearly: "[Value] is [assessment] — [percentile]th percentile. The typical range is [p25]-[p75]." |
Assessment values from norm: very_low, low, normal, high, very_high, anomalous.

Common categories: saas:churn_rate_monthly, saas:nps_score, saas:ltv_cac_ratio, ecommerce:cart_abandonment_rate, infrastructure:api_latency_p99, infrastructure:uptime_percentage.
This skill sends claims (natural language text) and metric values (category identifiers + numbers) to two external APIs. No documents, user data, or file contents are transmitted.
All via x402 protocol (USDC on Base). No authentication required for free tiers.
No personal data collected. Claims cached up to 1 hour (verify), metric checks are stateless (norm). Rate limiting uses IP hashing only.
