# Async REPL Protocol When working with Agentica's async REPL harness for testing. ## Rules ### 1. Use `await` for Future-returning tools ```python 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. ```python # 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)
