claims-validator
Validate documentation for unsupported claims, made-up metrics, and unverifiable statements.
Triggers
- "check for unsupported claims"
- "validate claims"
- "review for BS"
- "check metrics"
- "verify claims in this document"
- "find made-up stats"
Purpose
This skill identifies statements that make claims without evidence, including:
- Performance metrics without benchmarks or data
- Time/cost estimates without basis
- Percentage claims without citation
- Comparative statements without baselines
- Features described as implemented that don't exist
- Marketing superlatives presented as facts
Behavior
When triggered, this skill:
-
Scans for metric claims:
- Percentage improvements ("40% faster", "reduces by 60%")
- Time estimates ("saves 2-3 hours", "in minutes not hours")
- Cost projections ("$50-150/month", "ROI of 3x")
- Performance numbers ("99x faster", "sub-millisecond")
-
Identifies unsupported comparatives:
- "faster than", "better than", "more efficient"
- "best", "leading", "revolutionary", "game-changing"
- "comprehensive", "complete", "full-featured"
-
Checks for feature claims:
- Commands or flags mentioned that don't exist in codebase
- Features described in present tense that aren't implemented
- Integration claims without actual integration code
-
Validates citations:
- Claims that reference data should have sources
- Benchmarks should link to methodology
- Statistics should be reproducible
-
Generates report:
- List each claim found
- Classification (metric, comparative, feature, cost)
- Recommendation (remove, add citation, verify, rephrase)
Claim Categories
Metrics Without Data
# Flagged "Time Saved: 92-96% (9-15 hours → 45-60 minutes)" "99x faster routing" "45x cache speedup" # Problem No benchmark data, methodology, or reproducible test # Fix Remove claim, or add: "Based on [benchmark/test], measured [how]"
Cost Estimates Without Basis
# Flagged "Budget $20-50/month for moderate use" "Light usage: ~$10-20/month" "Enterprise teams may see $100-500+/month" # Problem No actual usage data, varies wildly by use case # Fix Remove specific numbers, or link to pricing calculator/methodology
Time Estimates Without Data
# Flagged "Deploy Full SDLC Framework (2 Minutes)" "5 minutes, replaces 2-4 hours manual work" "campaign setup from 2-3 weeks → 1 week" # Problem No measurement, varies by project complexity # Fix Remove time claims, describe what it does instead
Comparative Claims Without Baseline
# Flagged "faster than manual processes" "more efficient than traditional approaches" "better than existing solutions" # Problem No specific comparison, no baseline defined # Fix Remove comparison, or specify exactly what's being compared
Feature Claims for Unimplemented Features
# Flagged "aiwg -migrate-workspace # Optional migration tool" "Run 'config-validator --fix' to apply automated fixes" # Problem Command doesn't exist in codebase # Fix Remove until implemented, or mark as "Planned:"
Marketing Superlatives
# Flagged "comprehensive", "revolutionary", "game-changing" "best-in-class", "industry-leading", "cutting-edge" "seamless", "effortless", "zero-friction" # Problem Subjective claims that can't be verified # Fix Replace with specific, factual descriptions
Validation Report Format
# Claims Validation Report **Document**: README.md **Date**: 2025-12-09 **Claims Found**: 12 **Issues**: 8 ## Summary | Category | Found | Unsupported | Action Needed | |----------|-------|-------------|---------------| | Metrics | 5 | 4 | Remove or cite | | Time estimates | 3 | 3 | Remove | | Cost estimates | 2 | 2 | Remove | | Comparatives | 1 | 1 | Rephrase | | Features | 1 | 1 | Remove (not implemented) | ## Issues ### 1. Unsupported Metric **Line 204**: "Time Savings: 20-98% reduction across 5 core use cases" **Problem**: No benchmark data or methodology **Action**: Remove claim ### 2. Cost Estimate Without Data **Line 1180**: "Light usage: ~$10-20/month" **Problem**: No actual usage data to support estimate **Action**: Remove specific numbers ### 3. Non-existent Feature **Line 583**: "aiwg -migrate-workspace" **Problem**: Command not implemented **Action**: Remove until implemented ## Recommendations 1. **Remove all percentage-based time savings claims** 2. **Remove cost estimates** - direct users to measure their own usage 3. **Remove non-existent commands** - only document what exists 4. **Replace superlatives with specifics** - say what it does, not how good it is
Usage Examples
Validate a Document
User: "Check README.md for unsupported claims" Output: "Claims Validation: README.md Found 8 unsupported claims: Metrics (4): - Line 204: '20-98% reduction' - no data - Line 362: '56-63% time saved' - no data - Line 588: '99x faster routing' - no benchmark - Line 589: '45x cache speedup' - no benchmark Time Estimates (2): - Line 187: '5 minutes, replaces 2-4 hours' - unmeasured - Line 366: '2 Minutes' in heading - varies by project Non-existent Features (2): - Line 583: 'aiwg -migrate-workspace' - not implemented - Line 651: 'aiwg -rollback-workspace' - not implemented Recommendation: Remove these claims. Describe what features do, not how much time/money they save."
Quick Check
User: "Any BS in this section?" Output: "Found 2 issues: 1. 'Revolutionary approach' - marketing speak, be specific 2. '10x productivity gain' - no measurement Suggest: Replace with factual descriptions of functionality."
Integration
This skill complements:
- Voice Framework: Voice defines how to write, claims-validator checks what you claim
- config-validator: Validates config files, claims-validator validates prose claims
What This Skill Does NOT Flag
- Factual descriptions of features that exist
- Documented benchmarks with methodology
- Qualified statements ("may vary", "depending on", "in our testing")
- User testimonials clearly attributed
- Comparative claims with specific baselines cited
