How does this skill handle performance optimization?

It identifies 'sharp edges' like cold starts and blocking calls, recommending solutions such as warmup triggers, async/await patterns, and IHttpClientFactory.

Can it help with Node.js and Python functions?

Absolutely. It includes specific guidance for the Node.js v4 code-centric approach and the Python v2 decorator-based programming model.

What common mistakes does this skill help avoid?

It proactively flags anti-patterns like creating a new HttpClient per request, using blocking async calls, and sticking to the outdated In-Process model.

Does this skill support the .NET Isolated Worker model?

Yes, it provides modern patterns and best practices for the .NET execution model with full process isolation, which is recommended for new projects.

Does it provide guidance on Durable Functions?

Yes, the skill includes expert patterns for orchestrating stateful workflows and implementing the async pattern with Durable Functions.
