Model Troubleshooter - Expert System

🎯 MISSION

Automatically analyse user's complete OpenClaw setup, detect ALL available models, perform deep technical analysis, identify root cause with expert precision, and apply PERMANENT fixes that prevent recurrence forever.

🚀 AUTO-EXECUTION TRIGGERS

Automatic activation when user mentions:

• "model error", "fix model", "permanently fix"
• "baat baar error", "hamesha ke liye theek karo"
• "analyse my setup", "model analysis"
• Any model-related complaint

NO manual intervention needed — skill auto-runs full diagnosis.

🔬 PHASE 1: COMPLETE SETUP SCAN (Automatic)

Step 1.1: Load Full Configuration

# Get complete config
openclaw config.get

# Extract specifically:
- models.providers (all providers with URLs, API keys status)
- agents.defaults.model.primary (current active model)
- agents.list (all agent-specific overrides)
- channels (which models bound to which channels)
- tools.deny (any restricted tools affecting models)
- skills.entries (evolution settings, etc.)

Step 1.2: Detect All Available Models

For EACH provider in config:

• Provider Type: ZAI / NVIDIA / OpenRouter / Custom
• Base URL: Check endpoint health/reliability
• API Key Status: Valid/Expired/Redacted
• Models List: Extract all model IDs
• Capabilities: contextWindow, maxTokens, reasoning (yes/no)
• Cost Tier: Free vs Paid (:free suffix detection)

Step 1.3: Build Model Inventory

Create internal database:

{
  "totalProviders": 5,
  "totalModels": 19,
  "primaryModel": "qwen/qwen3.5-397b-a17b",
  "providersByReliability": [
    {"name": "zai", "tier": "S", "models": 3, "stability": "95%"},
    {"name": "NVIDIA", "tier": "A", "models": 7, "stability": "85%"},
    {"name": "OpenRouter", "tier": "B", "models": 9, "stability": "70%"}
  ],
  "recommendedFallbacks": ["zai/zai_glm-5-turbo", "minimaxai/minimax-m2.7"]
}

🧠 PHASE 2: DEEP TECHNICAL ANALYSIS

Step 2.1: Gateway Log Forensics

# Last 200 lines for patterns
Get-Content "C:\Users\IDL\.openclaw-autoclaw\logs\gateway.log" -Tail 200

# Extract:
- Error timestamps (frequency analysis)
- Error types (JSON, timeout, auth, connection)
- Provider-specific patterns
- Request/response latency
- Streaming chunk failures

Step 2.2: Error Pattern Matching

| Error Signature | Root Cause | Confidence | Permanent Fix |
|----------------|------------|------------|---------------|
| "Unexpected end of JSON" + event: error | NVIDIA streaming chunk corruption | 95% | Switch provider OR add chunk validation retry |
| "401 Unauthorized" | API key expired/rotated | 99% | Refresh API key from provider dashboard |
| "429 Too Many Requests" | Rate limit (free tier) | 98% | Upgrade tier OR switch to paid model |
| "timeout" after 30s | Model too slow for workload | 90% | Switch to faster model (GLM-5-Turbo) |
| "connection refused" | Endpoint down / firewall | 85% | Check network, switch provider |
| "model not found" | Typo in model ID | 99% | Correct model ID from provider docs |
| Repeated errors same time daily | Provider maintenance window | 80% | Schedule around downtime |

Step 2.3: Provider Health Check

For each provider:

1. Check baseUrl accessibility
2. Verify API key format (not expired)
3. Test with smallest model first
4. Measure response time
5. Check for rate limiting headers

Health Score:

• Excellent (90-100%): ZAI providers, paid NVIDIA
• Good (70-89%): Paid OpenRouter, recent models
• Fair (50-69%): Free tier, older models
• Poor (<50%): Deprecated endpoints, revoked keys

🔧 PHASE 3: EXPERT FIX APPLICATION

Fix Strategy Matrix

Based on root cause, apply ONE of these PERMANENT fixes:

Fix Type A: Provider Migration (Most Common)

When: Current provider unreliable (NVIDIA streaming errors, OpenRouter rate limits)

Action:

1. Identify user's MOST RELIABLE alternative from their config
2. Update agents.defaults.model.primary to that model
3. Apply: openclaw config.patch
4. Restart gateway
5. Verify with test request
6. Add monitoring: Log warnings if error recurs

Result: User permanently on stable provider.

Fix Type B: API Key Rotation

When: 401 errors, expired keys

Action:

1. Detect which provider's key expired
2. Extract provider dashboard URL from config
3. Instruct user: "Go to [URL], generate new key"
4. User provides new key
5. Update config: openclaw config.patch with new key
6. Test immediately
7. Add reminder: Set calendar event for key expiry (if provider shows expiry date)

Result: Fresh key, no auth errors for next validity period.

Fix Type C: Chunk Validation + Retry Logic

When: "Unexpected end of JSON" from streaming APIs

Action:

1. Update config to enable compaction:

   {
     "agents": {
       "defaults": {
         "compaction": {
           "reserveTokensFloor": 40000
         },
         "timeoutSeconds": 1800
       }
     }
   }

1. If using NVIDIA/OpenRouter, add fallback logic:

• On first streaming error: auto-retry once
• On second error: switch to non-streaming mode
• On third error: failover to Tier 1 provider

1. Apply config + restart
2. Add permanent safeguard: Evolution rule to detect early warnings

Result: Streaming errors handled gracefully, no user-visible failures.

Fix Type D: Rate Limit Elimination

When: 429 errors from free tier models

Action:

1. Identify which model hitting rate limit
2. Check user's paid alternatives
3. Switch to paid model OR upgrade tier
4. If no paid option: implement request queuing (max 1 req/min)
5. Apply: openclaw config.patch
6. Add monitoring: Track daily request count

Result: No more rate limit blocks.

Fix Type E: Network/Endpoint Fix

When: Connection refused, timeouts from specific endpoint

Action:

1. Check if baseUrl reachable (ping test)
2. If endpoint down: switch to mirror/alternative provider
3. If firewall blocking: instruct user to whitelist domain
4. Apply config change
5. Add health check: Daily ping test via heartbeat

Result: Always-connected model access.

✅ PHASE 4: VERIFICATION & FUTURE-PROOFING

Step 4.1: Immediate Verification

# Test new configuration
openclaw sessions.list --limit 1

# Watch logs for 2 minutes
Get-Content "C:\Users\IDL\.openclaw-autoclaw\logs\gateway.log" -Tail 20 -Wait

# Confirm: NO errors in test period

Step 4.2: Permanence Checklist

Before declaring "fixed forever":

• [ ] Root cause addressed (not just symptom)
• [ ] Alternative provider available as backup
• [ ] Config changes persisted to openclaw.json
• [ ] Gateway restarted successfully
• [ ] No errors in verification test
• [ ] User educated on warning signs
• [ ] Monitoring/heartbeat set up if needed

Step 4.3: Future-Proofing

Add safeguards:

1. Evolution Rule: If same error appears twice in 24h → auto-escalate to expert mode
2. Heartbeat Check: Daily model health status
3. Fallback Chain: Configured top 3 models ready for instant switch
4. Documentation: Update MEMORY.md with what broke + how fixed
