Show HN: SafeAgent – exactly-once execution guard for AI agents
1 comments
This becomes a real issue once agents start interacting with external systems. Retries are easy to miss during development, but once you add tool calls + network failures the agent loop can replay same action multiple times.
Idempotency/request IDs end up becoming pretty important for anything that touches emails, payments, tickets etc

This becomes dangerous when the action is irreversible: - sending emails - opening tickets - executing trades - triggering payouts
SafeAgent is a small Python library that enforces exactly-once execution for agent actions using request-ID deduplication.
Example:
from settlement.settlement_requests import SettlementRequestRegistry
registry = SettlementRequestRegistry()
def send_email(): print("EMAIL SENT")
registry.execute( request_id="email:user123:invoice", action="send_email", payload={"to": "[email protected]"}, execute_fn=send_email )
If the same request_id is replayed, the action does not run again.
Instead the original execution receipt is returned.
