Claude-skill-registry 32-analyze-verify-150
[32] ANALYZE. Ensure every critical claim has verifiable evidence with confidence levels. Each fact must have source + confidence percentage. If confidence <85%, enter Loop150 to find more sources. Use for critical decisions, factual claims, legal/compliance work, or any situation where unverified claims are dangerous.

Core Principle: No claim without proof. Every critical fact needs: source + confidence level. If unsure, keep digging until confident or escalate to user.
What This Skill Does
When you invoke this skill, you're asking AI to:
- Source every claim — Trace facts to verifiable sources
- Quantify confidence — Express certainty as percentage
- Verify independently — Cross-check from multiple sources
- Loop until confident — Keep researching if <85% confidence
- Escalate when stuck — Ask user if sources exhausted
The 150% Proof Rule
| Dimension | 100% Core | +50% Enhancement |
|---|---|---|
| Source | Primary source identified | + Independent confirmation |
| Confidence | Percentage stated | + Reasoning documented |
| Verification | Single source check | + Multi-source cross-validation |
| Gaps | Note uncertainties | + Active Loop150 to fill gaps |
Confidence Level Framework
| Level | % Range | Description | Action Required |
|---|---|---|---|
| Verified | 95-100% | Multiple primary sources, no contradictions | Use in critical decisions |
| Strong | 85-94% | Reliable sources, minor uncertainties | Safe for most purposes |
| Moderate | 75-84% | Limited sources, some gaps | Flag for verification |
| Weak | 50-74% | Insufficient evidence, major gaps | Do not use without confirmation |
| Insufficient | <50% | Contradictory or missing | Reject, research further |
When to Use This Skill
- Critical decisions — Where wrong facts cause real damage
- Legal/compliance — Where accuracy has legal implications
- Architecture decisions — Where claims drive major choices
- Stakeholder communication — Where credibility matters
- Any high-stakes claim — When you can't afford to be wrong
Execution Protocol
Step 1: CLAIM FORMULATION
State the fact clearly:
🔍 **Claim:** [Precise factual statement] **Context:** [Why this matters] **Critical Level:** [High/Medium/Low]
Step 2: PRIMARY SOURCE
Find the original source:
- Locate primary evidence
- Verify authenticity
- Extract direct quote/data
Step 3: SECONDARY CONFIRMATION
Find independent corroboration:
- Different source type
- Cross-reference data
- Check consistency
Step 4: CONFIDENCE ASSESSMENT
Calculate confidence:
**Evidence Evaluation:** ├── Primary Source: [Quality assessment] ├── Secondary Sources: [Count and quality] ├── Contradictions: [Any found?] └── Gaps: [What's missing?] **Confidence:** [X]% **Reasoning:** [Why this percentage]
Step 5: DECISION
Confidence ≥85%? ├─ YES → Use fact with stated confidence └─ NO → Enter Loop150
Loop150 Continuous Verification
When confidence <85%:
🔄 **LOOP150 ACTIVATED** (Current: [X]%) ITERATION 1: EXPAND SOURCES ├── Identify new source types ├── Use alternative research methods ├── Broaden search scope ↓ ITERATION 2: DEEPER ANALYSIS ├── Drill into source details ├── Verify source credibility ├── Check contextual factors ↓ ITERATION 3: CROSS-VALIDATION ├── Compare against known facts ├── Test logical consistency ├── Seek expert corroboration ↓ RECALCULATE: New confidence = [Y]% Continue loop until: ├─ ≥90% achieved → EXIT, proceed with confidence └─ Sources exhausted → ESCALATE to user
Source Quality Criteria
🔍 RELIABILITY FACTORS:
- Authority: Official, expert, or primary source?
- Currency: How recent and up-to-date?
- Objectivity: Free from bias or agenda?
- Methodology: Sound research methods used?
- Independence: Not dependent on other sources?
📊 EVIDENCE STRENGTH:
| Type | Strength | Example |
|---|---|---|
| Primary | High | Original data, first-hand |
| Secondary | Medium | Analysis of primary |
| Tertiary | Low | Summaries, reviews |
| Statistical | High | Large sample, proper method |
| Anecdotal | Variable | Personal experience |
Output Format
🔍 **PROOF-GRADE 150 VERIFICATION** **Claim:** [Precise factual statement] **Primary Source:** - [File/location/date] - "[Direct quote or data]" **Secondary Sources:** - [Source 2]: [Confirmation] - [Source 3]: [Confirmation] **Confidence Level:** [X]% **Reasoning:** [Why this level] **Validation Method:** [How verified] **Outstanding Issues:** [Any uncertainties] **Status:** ✅ VERIFIED | ⚠️ NEEDS CONFIRMATION | ❌ INSUFFICIENT
Operational Rules
- EVERY CRITICAL CLAIM: Requires proof-grade validation
- SOURCE FIRST: Identify source before using fact
- CONFIDENCE REQUIRED: Every fact has percentage
- LOOP150 MANDATORY: <85% triggers verification loop
- TRANSPARENCY: Document all sources and reasoning
- ESCALATE HONESTLY: If sources exhausted, ask user
Failure Modes & Recovery
| Failure | Detection | Recovery |
|---|---|---|
| Unverified Claims | Facts without sources | Immediate verification, Loop150 |
| Overconfidence | Inflated percentages | Recalculate with scrutiny |
| Source Bias | Only confirming sources | Actively seek contradictions |
| Incomplete Docs | Missing source trail | Document all sources now |
Examples
❌ Without Proof-Grade
AI: "The API response time is fast enough" Source: "Feels fast to me" Result: Performance issues in production
✅ With Proof-Grade 150
🔍 PROOF-GRADE 150 VERIFICATION Claim: "API response time is consistently under 200ms" Primary Source: - /tests/performance/load_test_results.json - "p99 latency: 187ms across 10,000 requests" Secondary Sources: - Production monitoring (last 7 days): avg 156ms - APM dashboard: p95 = 178ms Confidence Level: 95% Reasoning: Multiple measurement sources, consistent results, production data confirms test environment findings. Validation Method: Cross-referenced test data with production metrics Status: ✅ VERIFIED FOR USE
Relationship to Other Skills
- research-deep-150 → Gathers evidence
- proof-grade-150 → Validates and quantifies confidence
- integrity-check-150 → Final quality verification
Remember: Proof-grade isn't about being slow — it's about being trustworthy. A 95% confidence claim is more valuable than an unverified assertion. When stakes are high, proof-grade protects everyone.
