Neverdie

NeverDie — LLM Resilience Skill

Ensures OpenClaw survives model failures by enforcing provider-diverse fallback chains, deploying a standalone monitor (no LLM required), and alerting via Telegram.

Core Principle: Provider Diversity

Never stack 3+ models from the same provider in a row. Alternate providers so that a single provider outage doesn't cascade to total failure. Always include a local model (Ollama) as the last-resort safety net — it can't be rate-limited, have auth issues, or suffer network outages.

Good chain: anthropic/claude-haiku-4-5 → openai/gpt-4.1-mini → ollama/llama3.2:3b Bad chain: anthropic/claude-haiku-4-5 → anthropic/claude-sonnet-4-6 → anthropic/claude-opus-4-6

Instructions

1. Diagnose Current Config

Read ONLY the model chain from ~/.openclaw/openclaw.json (do NOT read or output API keys, tokens, or auth config):

• Check primary and fallbacks for provider diversity
• Flag if all models are from the same provider
• Flag if no local model (Ollama) is present
• Flag if the NeverDie monitor cron job is missing or disabled

node -e "
  const cfg = JSON.parse(require('fs').readFileSync(process.env.HOME + '/.openclaw/openclaw.json', 'utf8'));
  const m = cfg.agents.defaults.model;
  console.log('Primary:', m.primary);
  console.log('Fallbacks:', JSON.stringify(m.fallbacks));
  const providers = [m.primary, ...m.fallbacks].map(id => id.split('/')[0]);
  const unique = [...new Set(providers)];
  console.log('Providers:', unique.join(', '));
  if (unique.length < 2) console.log('WARNING: All models from same provider!');
  if (!providers.includes('ollama')) console.log('WARNING: No local Ollama fallback!');
"

Security note: This script only outputs model IDs and provider names. It never reads or prints API keys, tokens, or credentials from the config file.

2. Configure Provider-Diverse Fallback Chain

Ensure at least 2 different cloud providers + 1 local (Ollama) in the chain. Recommended pattern:

{
  "primary": "anthropic/claude-haiku-4-5",
  "fallbacks": [
    "openai/gpt-4.1-mini",
    "ollama/llama3.2:3b",
    "nvidia/moonshotai/kimi-k2.5"
  ]
}

Rules:

• Primary should be the fastest/cheapest model for the workload
• First fallback should be from a DIFFERENT cloud provider
• Ollama should always be in the chain (ideally position 2 or 3)
• Additional fallbacks from other providers are bonus redundancy

3. Deploy the Standalone Monitor

Copy the parameterized monitor to the workspace:

cp ~/.openclaw/workspace/skills/neverdie/scripts/fallback-monitor.js ~/.openclaw/workspace/fallback-monitor.js
chmod +x ~/.openclaw/workspace/fallback-monitor.js

The monitor reads config from ~/.openclaw/workspace/.neverdie-config.json:

{
  "telegramBotToken": "YOUR_BOT_TOKEN",
  "telegramChatId": "YOUR_CHAT_ID",
  "cooldownMinutes": 15,
  "timezone": "UTC",
  "hostname": "my-openclaw"
}

Telegram is optional. Without it, the monitor still writes alerts to .fallback-alert-latest.json and stdout.

If no config file exists, it falls back to environment variables:

• NEVERDIE_TELEGRAM_TOKEN
• NEVERDIE_TELEGRAM_CHAT_ID

4. Register the Cron Job

Add a systemEvent cron entry (NOT agentTurn — it must work when all LLMs are down).

Use the full absolute path to the deployed monitor (not ~/):

{
  "id": "<generate-uuid>",
  "agentId": "main",
  "name": "NeverDie Fallback Monitor",
  "enabled": true,
  "createdAtMs": <now>,
  "updatedAtMs": <now>,
  "schedule": {
    "kind": "every",
    "everyMs": 300000,
    "anchorMs": <now>
  },
  "sessionTarget": "isolated",
  "wakeMode": "now",
  "payload": {
    "kind": "systemEvent",
    "text": "exec:node /home/USER/.openclaw/workspace/fallback-monitor.js"
  },
  "delivery": {
    "mode": "announce",
    "channel": "session",
    "bestEffort": true
  },
  "state": {}
}

5. Configure Alerts

Ask the user for their Telegram bot token and chat ID, then write ~/.openclaw/workspace/.neverdie-config.json.

To get these:

1. Message @BotFather on Telegram → /newbot → copy the token
2. Message the bot, then visit https://api.telegram.org/bot<TOKEN>/getUpdates to find the chat ID

Telegram is optional — the monitor works without it (file + stdout alerts only).

6. Verify

# Check status
node ~/.openclaw/workspace/fallback-monitor.js --status

# Send a test Telegram alert
node ~/.openclaw/workspace/fallback-monitor.js --test

# Normal run (scan logs)
node ~/.openclaw/workspace/fallback-monitor.js

7. Status Check

When the user asks for NeverDie status, run node ~/.openclaw/workspace/fallback-monitor.js --status and also check:

1. Fallback chain — read openclaw.json and assess provider diversity
2. Monitor cron — is the job in jobs.json? Enabled? Last run status?
3. Ollama — is the local model reachable?

curl -s --max-time 3 http://localhost:11434/api/tags | node -e "
  let d='';process.stdin.on('data',c=>d+=c);process.stdin.on('end',()=>{
    try{const r=JSON.parse(d);console.log('Ollama:',r.models.map(m=>m.name).join(', '))}
    catch(e){console.log('Ollama: NOT REACHABLE')}
  })
"

What the Monitor Detects

Security

• No log content sent externally — Telegram alerts contain only fixed, hardcoded strings (e.g. "All models failed — no LLM available"). Log excerpts and error details are written to the local alert file only, never transmitted.
• No secrets in code — Telegram bot token is stored in .neverdie-config.json at runtime, never in skill files
• Config isolation — the diagnostic only reads model IDs from openclaw.json, never API keys or credentials
• No network installs — zero npm dependencies, no remote downloads, only Node.js builtins (fs, path, https)
• Telegram is optional — file-only alerts work without any external network calls
• Outbound scope — the only external endpoint contacted is api.telegram.org, and only when Telegram is explicitly configured by the user
• Runs as a systemEvent cron job, completely independent of LLM availability
• Re-running setup is idempotent — it skips the cron job if one already exists
