When does this happen?
IF When using create_supervisor with multiple sub-site_1, the first invocation of the 'transfer_back_to_supervisor' tool fails with 'is not a valid tool' error.
How others solved it
THEN Work around the race condition by ensuring the supervisor is fully initialized before any agent tool call. Implement a retry mechanism for the first transfer attempt, or explicitly call supervisor.invoke with a dummy input to stabilize internal state before production use.
# Retry logic for first supervisor handoff
try:
result = supervisor.invoke("start")
except Exception as e:
if "transfer_back_to_supervisor" in str(e):
# retry after brief delay or reinitialize supervisor
import time
time.sleep(0.1)
result = supervisor.invoke("start")Related patterns
