"""Regression: agent_tools._truncate must always return a string.
|
|
|
|
It did `len(text)` directly, so `_truncate(None)` raised TypeError. Returning
|
|
the raw non-string just moves the crash downstream (callers treat it as text),
|
|
so non-strings are now coerced to a string and still truncated.
