Verified Completion Rate
Definition
Verified Completion Rate is the percentage of an agent’s claimed completed actions that are independently verified as correct against the system of record.
Formula
Verified Completion Rate = verified completions / claimed completions
Example dashboard
For an agent that claimed 1,000 completed refunds and cancellations, Postcept verifies each one against the system of record and surfaces the real reliability number, plus exactly where the gap came from.

Why claimed success is not enough
Agent success rates and eval scores measure what an agent or benchmark thinks happened. They are computed from the agent’s own outputs, so they inherit the agent’s blind spots: a confident tool call that silently failed still counts as a success.
Verified Completion Rate is computed from the system of record instead. It is the difference between an agent that looks reliable and one you can prove is.
How VCR improves agent operations
Because every gap is attributed, false completion, duplicate, mismatch, or policy failure, teams can see exactly which failure modes are dragging the number down and fix them. As Postcept catches recurring patterns and they are addressed, Verified Completion Rate climbs and stays measurable over time.
Each verified action also leaves a signed completion receipt, so the metric is backed by evidence, not estimation.
