How does this skill handle API reliability and network errors?

It implements industry-standard resilience patterns including exponential backoff with jitter, automatic retries for 429 and 5xx errors, and circuit breaker strategies.

Does it include support for modern pagination techniques?

Yes, the skill focuses on developer-friendly pagination using async iterators in TypeScript and Python, as well as channel-based patterns in Go.

What programming languages does this SDK design skill support?

This skill provides specific patterns and architectural guidance for TypeScript, Python, and Go, covering both synchronous and asynchronous implementations.

Can I use this for internal company services?

Absolutely. While it follows public-facing standards like Stripe or AWS, these patterns are ideal for creating consistent internal SDKs for microservices.
