A successful tool call doesn't mean the agent made the right decision
djgoel123 · reddit · 2026-10-26
A developer highlights a blind spot in agent reliability: an agent can call the right API, get a success response, and finish the workflow cleanly—while updating the wrong customer's account. Monitoring sees everything as fine.
The author proposes separating three questions:
- Did the agent understand the request correctly?
- Did it pick the right action and target?
- Did the system execute it safely?
For sensitive operations, they'd add authorization checks, audit logs, and confirmation before irreversible changes, asking the community how they evaluate decision quality beyond execution success.
