Async REPL Protocol
When working with Agentica's async REPL harness for testing.
Rules
1. Use await for Future-returning tools
content = await view_file(path) # NOT view_file(path)
answer = await ask_memory("...")
2. Single code block per response
Compute AND return in ONE block. Multiple blocks means only first executes.
# GOOD: Single block
content = await view_file(path)
return any(c.isdigit() for c in content)
# BAD: Split blocks (second block never runs)
content = await view_file(path)
