The description names the domain (Azure Messaging SDKs for Event Hubs and Service Bus) and lists categories of issues (connection failures, authentication errors, message processing issues, SDK configuration problems), but doesn't list specific concrete actions like 'diagnose AMQP connection errors' or 'resolve message lock lost exceptions'. The actions are more categorical than concrete.

Clearly answers both 'what' (troubleshoot and resolve issues with Azure Messaging SDKs covering connection failures, auth errors, message processing, SDK config) and 'when' with an explicit 'WHEN:' clause containing extensive trigger scenarios. The explicit trigger guidance is thorough.

Excellent coverage of natural trigger terms users would actually say, including specific error scenarios ('message lock lost', 'send timeout', 'receiver disconnected', 'event hub not receiving messages', 'service bus dead letter'), language-specific terms ('eventhub python', 'servicebus java', 'servicebus dotnet'), and common phrasing variations ('AMQP error', 'event processor host issue').

Highly distinctive with a clear niche focused specifically on Azure Messaging SDKs (Event Hubs and Service Bus). The combination of specific Azure services, SDK troubleshooting context, and detailed trigger terms like 'AMQP error', 'event processor host issue', and 'service bus dead letter' make it very unlikely to conflict with other skills.

Mostly efficient but has some redundancy — the 'References' section and 'Reference Index' section overlap with 'Connectivity Troubleshooting' which already links to service-troubleshooting.md. The 'When to Use This Skill' section partially duplicates the description. The Quick Reference table adds modest value but isn't padded.

Provides tool names and a diagnostic workflow with concrete steps, but lacks executable code examples, specific KQL queries for log analysis, or concrete command invocations showing exact parameters. The guidance is structured but remains at the 'what to do' level rather than 'exactly how to do it' level.

The 6-step diagnosis workflow is clearly sequenced and logical, but lacks explicit validation checkpoints or feedback loops. There's no 'if this fails, try that' branching, and no verification step to confirm the fix worked. For a troubleshooting skill involving potentially destructive operations (configuration changes), this is a gap.

Excellent progressive disclosure with a clear overview, well-organized SDK-specific references by language, a reference index with explicit 'when to load' guidance, and one-level-deep links to detailed materials. The instruction to load on demand is a nice touch.
