What this skill does

# Anthropic Incident Runbook

## Overview

Respond to Anthropic API incidents in production — outages, sustained 529 errors, authentication failures, and timeouts. Covers status page checking, severity classification, model fallback activation, communication, and post-incident review.

## Step 1: Confirm the Issue

```bash
# Check Anthropic status
curl -s https://status.anthropic.com/api/v2/status.json | python3 -c "
import json, sys
d = json.load(sys.stdin)
print(f\"Status: {d['status']['description']} ({d['status']['indicator']})\")"

# Test API directly
curl -s -w "\nHTTP %{http_code} in %{time_total}s\n" \
  https://api.anthropic.com/v1/messages \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "claude-version: 2023-06-01" \
  -H "content-type: application/json" \
  -d '{"model":"claude-haiku-4-5-20251001","max_tokens":5,"messages":[{"role":"user","content":"ping"}]}'
```

## Step 2: Classify Severity

| Symptom | Severity | Action |
|---------|----------|--------|
| 529 overloaded (intermittent) | Low | SDK auto-retries handle this |
| 529 overloaded (sustained 5+ min) | Medium | Switch to fallback model |
| 401/403 on all requests | High | API key issue — check console |
| All requests timing out | High | Check status page, activate fallback |
| Status page shows incident | Varies | Follow status page updates |

## Step 3: Activate Fallback

```typescript
async function callWithFallback(params: Anthropic.MessageCreateParams) {
  try {
    return await client.messages.create(params);
  } catch (err) {
    if (err instanceof Anthropic.APIError && (err.status === 529 || err.status === 500)) {
      // Try a different model
      if (params.model.includes('opus')) {
        return await client.messages.create({ ...params, model: 'claude-sonnet-4-20250514' });
      }
      if (params.model.includes('sonnet')) {
        return await client.messages.create({ ...params, model: 'claude-haiku-4-5-20251001' });
      }
    }
    throw err;
  }
}
```

## Step 4: Communicate

- Update your status page if user-facing
- Note: Anthropic incidents typically resolve in 15-60 minutes

## Step 5: Post-Incident

- Check your error logs for the incident window
- Calculate impact (failed requests, user impact)
- Verify all systems recovered

## Output

- Incident confirmed via status page and direct API test
- Severity classified (Low/Medium/High) based on symptoms
- Fallback activated if needed (downgrade model or queue requests)
- Impact assessed and documented post-incident

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| API Error | Check error type and status code | See `clade-common-errors` |

## Examples

See Step 1 (curl status check and API test), Step 2 (severity classification table), Step 3 (fallback code with model downgrade), and Step 5 (post-incident checklist) above.

## Next Steps

See `clade-reliability-patterns` for building resilient integrations.

## Prerequisites

- Production Claude integration deployed
- Fallback model configuration in place (see `clade-reliability-patterns`)
- Monitoring/alerting configured (see `clade-observability`)

## Instructions

### Step 1: Review the patterns below

Each section contains production-ready code examples. Copy and adapt them to your use case.

### Step 2: Apply to your codebase

Integrate the patterns that match your requirements. Test each change individually.

### Step 3: Verify

Run your test suite to confirm the integration works correctly.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
