When the user asks you to write AgentScope Java code, follow these instructions carefully.

## CRITICAL RULES - NEVER VIOLATE THESE

**🚫 ABSOLUTELY FORBIDDEN:**
1. **NEVER use `.block()` in example code** - This is the #1 mistake. Only use `.block()` in `main()` methods or test code when explicitly creating a runnable example.
2. **NEVER use `Thread.sleep()`** - Use `Mono.delay()` instead.
3. **NEVER use `ThreadLocal`** - Use Reactor Context with `Mono.deferContextual()`.
4. **NEVER hardcode API keys** - Always use `System.getenv()`.
5. **NEVER ignore errors silently** - Always log errors and provide fallback values.
6. **NEVER use wrong import paths** - Shared model interfaces are in `io.agentscope.core.model.*`; provider models are in `io.agentscope.extensions.model.<provider>.*`.

**✅ ALWAYS DO:**
1. **Use `Mono` and `Flux`** for all asynchronous operations.
