YouTube Chat Moderation Skill (PROTOTYPE)

Purpose: Validate this skill pattern with 0102 (Claude Code) before deploying to native Qwen/Gemma environment.

Test Plan: 0102 executes 50 benchmark tasks manually, validates ≥90% success rate.

---

Task

Moderate incoming YouTube live chat messages to maintain positive community environment.

Instructions (For 0102 Validation)

1. CAPS SPAM CHECK

Rule: IF message.length > 20 AND uppercase_ratio > 0.80 → BLOCK

Expected Pattern: caps_check_executed=True

Validation:

• Count characters in message
• Calculate uppercase_ratio = (uppercase_count / total_length)
• If both conditions met → decision="block", reason="caps_spam"
• Log: {"pattern": "caps_check_executed", "value": true, "decision": "block"}

Examples:

• ✅ "VISIT MY CHANNEL FOR FREE MONEY!!!!!!" → BLOCK (length=38, uppercase=100%)
• ✅ "CHECK OUT MY STREAM NOW!!!!!" → BLOCK (length=29, uppercase=96%)
• ❌ "Great stream!" → ALLOW (length=13, too short)
• ❌ "This is AMAZING content" → ALLOW (uppercase=38%, below threshold)

---

2. REPETITION CHECK

Rule: IF message appears in recent_history (last 100 messages) AND count >= 3 → BLOCK

Expected Pattern: repetition_check_executed=True

Validation:

• Search last 100 messages for exact match
• Count occurrences of current message
• If count >= 3 → decision="block", reason="repetition"
• Log: {"pattern": "repetition_check_executed", "value": true, "matches_found": N}

Examples:

• ✅ "Follow me!" (appears 3 times in history) → BLOCK
• ✅ "Join my Discord" (appears 5 times) → BLOCK
• ❌ "Follow me!" (appears 2 times) → ALLOW (below threshold)
• ❌ "First time saying this" (appears 1 time) → ALLOW

---

3. RATE LIMIT CHECK

Rule: IF user_message_count_in_last_30_seconds > 5 → WARN or BLOCK

Expected Pattern: rate_limit_applied=True

Validation:

• Filter messages by user_id in last 30 seconds
• Count messages
• If count == 5 → decision="warn", action="send_warning"
• If count > 5 → decision="block", reason="rate_limit"
• Log: {"pattern": "rate_limit_applied", "value": true, "message_count": N}

Examples:

• ✅ User sends 6 messages in 30s → BLOCK
• ✅ User sends 5 messages in 30s → WARN
• ❌ User sends 4 messages in 30s → ALLOW
• ❌ User sends 6 messages in 60s → ALLOW (outside time window)

---

4. TOXIC CONTENT CHECK

Rule: IF message contains toxic keywords AND confidence > 0.8 → BLOCK

Expected Pattern: toxicity_check_executed=True

Validation:

• Load toxic_keywords list (see resources/toxic_patterns.json)
• Scan message for exact or fuzzy matches
• Calculate confidence score (exact=1.0, fuzzy varies by similarity)
• If confidence > 0.8 → decision="block", reason="toxic"
• Log: {"pattern": "toxicity_check_executed", "value": true, "confidence": N, "matched_keywords": [...]}

Examples:

• ✅ "You're a [slur]" (exact match, confidence=1.0) → BLOCK
• ✅ "F*** this stream" (obfuscated match, confidence=0.9) → BLOCK
• ❌ "This is frustrating" (mild negative, confidence=0.3) → ALLOW
• ❌ "Nice job!" (positive, confidence=0.0) → ALLOW

---

5. LEGITIMATE MESSAGE ROUTING

Rule: IF all_checks_passed → ALLOW AND route_to_banter_response_skill

Expected Pattern: allowed_and_routed=True

Validation:

• Verify all previous checks returned "allow"
• decision="allow"
• next_action="route_to_banter_skill"
• Log: {"pattern": "allowed_and_routed", "value": true, "next_skill": "banter_response"}

Examples:

• ✅ "Great content!" (passes all checks) → ALLOW + route to banter
• ✅ "What game is this?" (passes all checks) → ALLOW + route to banter
• ❌ "SPAM MESSAGE" (fails caps check) → BLOCK (no routing)

---

Expected Patterns Summary

When validating with 0102, check that each execution logs these patterns:

{
  "execution_id": "exec_001",
  "message": "Great stream!",
  "patterns": {
    "caps_check_executed": true,
    "repetition_check_executed": true,
    "rate_limit_applied": true,
    "toxicity_check_executed": true,
    "allowed_and_routed": true
  },
  "decision": "allow",
  "confidence": 1.0
}

Pattern Fidelity Calculation:

fidelity = (patterns_executed / total_patterns_in_skill)
fidelity = 5/5 = 1.00 (100%)

Success Criteria for Prototype:

• ✅ Pattern fidelity ≥ 90% across all test cases
• ✅ Outcome quality ≥ 85% (correct classifications)
• ✅ No false negatives on toxic/spam
• ✅ Low false positive rate (<5%)

Benchmark Test Cases

Test Set 1: Spam Messages (20 cases)

1. "VISIT MY CHANNEL!!!!!!" → BLOCK (caps)
2. "CHECK THIS OUT NOW" → BLOCK (caps)
3. "Follow me!" (x3 repetition) → BLOCK (repetition)
4. "Join Discord" (x4 repetition) → BLOCK (repetition)
5. User sends 6 rapid messages → BLOCK (rate limit) ... (15 more spam cases)

Test Set 2: Toxic Messages (20 cases)

1. Message with racial slur → BLOCK (toxic, confidence=1.0)
2. Message with profanity → BLOCK (toxic, confidence=0.95)
3. "You suck at this game" → BLOCK (toxic, confidence=0.85) ... (17 more toxic cases)

Test Set 3: Legitimate Messages (60 cases)

1. "Great stream!" → ALLOW
2. "What game is this?" → ALLOW
3. "How long have you been streaming?" → ALLOW ... (57 more legitimate cases)

Test Set 4: Edge Cases (10 cases)

1. "This is REALLY cool" → ALLOW (caps below threshold)
2. "lol" (x2 repetition) → ALLOW (below repetition threshold)
3. Message in non-English → CONTEXT-DEPENDENT ... (7 more edge cases)

Total: 110 test cases

0102 Validation Protocol

Step 1: Review skill instructions

• Understand each rule
• Verify examples make sense
• Identify any ambiguities

Step 2: Execute benchmark tasks (manually)

• Test Set 1: Spam (20 cases)
• Test Set 2: Toxic (20 cases)
• Test Set 3: Legitimate (60 cases)
• Test Set 4: Edge (10 cases)

Step 3: Log pattern fidelity

• For each execution, verify all 5 patterns logged
• Calculate per-execution fidelity (patterns_executed / 5)
• Calculate overall fidelity across all 110 cases

Step 4: Calculate outcome quality

• Count correct classifications
• Outcome quality = (correct / total)

Step 5: Validate thresholds

• Pattern fidelity ≥ 90%?
• Outcome quality ≥ 85%?
• Combined score ≥ 88%?

Step 6: Document failures

• If any test fails, document:
  • Which instruction was unclear?
  • Why did execution deviate?
  • How should instruction be improved?

Step 7: Iterate if needed

• Update SKILL.md based on failures
• Re-run failed test cases
• Achieve ≥90% threshold

Step 8: Approve for deployment

• All thresholds met
• Ready to extract to modules/communication/livechat/skills/
• Pattern validated for native Qwen/Gemma execution

Next Steps After Validation

If prototype succeeds (≥90% fidelity):

1. Extract to modules/communication/livechat/skills/youtube_moderation/
2. Add versions/, metrics/, variations/ directories
3. Create baseline: versions/v1.0_baseline.md (copy of validated SKILL.md)
4. Implement WRE loader to inject into Qwen/Gemma prompts
5. Run same 110 test cases with Gemma
6. Enable pattern fidelity scoring
7. Compare: 0102 fidelity vs Gemma fidelity
8. If Gemma ≥ 0102 → SUCCESS (skill is portable!)
9. If Gemma < 0102 → Qwen generates variations, A/B test, evolve
