majiayu000 Proof-Grade 150 Protocol
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.
