# 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
```powershell
# 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:
```json
{
  "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
```powershell
# 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:
   ```json
   {
     "agents": {
       "defaults": {
         "compaction": {
           "reserveTokensFloor": 40000
         },
         "timeoutSeconds": 1800
       }
     }
   }
   ```
2. 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
3. Apply config + restart
4. **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
```powershell
# 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

## 🛡️ EXPERT RULES

1. **Never guess** — always scan config first
2. **Never apply temporary fix** — only permanent solutions
3. **Never switch without confirmation** — unless critical error blocking all work
4. **Always verify** — test after every fix
5. **Always educate** — tell user WHAT broke and WHY it won't break again
6. **Always backup** — note what changed in MEMORY.md
7. **Never expose secrets** — API keys always REDACTED in logs/output
