# Azure Messaging SDK Troubleshooting

## Quick Reference

| Property | Value |
|----------|-------|
| **Services** | Azure Event Hubs, Azure Service Bus |
| **MCP Tools** | `mcp_azure_mcp_eventhubs`, `mcp_azure_mcp_servicebus` |
| **Best For** | Diagnosing SDK connection, auth, and message processing issues |

## When to Use This Skill

- SDK connection failures, auth errors, or AMQP link errors
- Message lock lost, session lock, or send/receive timeouts
- Event processor or message handler stops processing
- SDK configuration questions (retry, prefetch, batch size)

## MCP Tools

| Tool | Command | Use |
|------|---------|-----|
| `mcp_azure_mcp_eventhubs` | Namespace/hub ops | List namespaces, hubs, consumer groups |
| `mcp_azure_mcp_servicebus` | Queue/topic ops | List namespaces, queues, topics, subscriptions |
| `mcp_azure_mcp_monitor` | `logs_query` | Query diagnostic logs with KQL |
| `mcp_azure_mcp_resourcehealth` | `get` | Check service health status |
| `mcp_azure_mcp_documentation` | Doc search | Search Microsoft Learn for troubleshooting docs |

## Diagnosis Workflow

1. **Identify the SDK and version** — Ask which language SDK and version the user is on
2. **Check resource health** — Use `mcp_azure_mcp_resourcehealth` to verify the namespace is healthy
3. **Review the error message** — Match against language-specific troubleshooting guide
4. **Look up documentation** — Use `mcp_azure_mcp_documentation` to search Microsoft Learn for the error or topic
5. **Check configuration** — Verify connection string, entity name, consumer group
6. **Recommend fix** — Apply remediation, citing documentation found

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".

Backend & APIsscripts

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.
