By default, event-based suggestion features like proactive generative knowledge assist (PGKA) send a Pub/Sub notification for every suggestion attempt. This means Agent Assist sends a notification even when the feature determines there is no relevant suggestion to provide, resulting in an empty response. This can create unnecessary Pub/Sub traffic and processing overhead. You can suppress empty notifications with a single code field: skip_empty_event_based_suggestion.
Basics
The skip_empty_event_based_suggestion field is part of SuggestionConfig within HumanAgentAssistantConfig of your conversation profile. When you set its value to true, Agent Assist only sends a Pub/Sub notification when it generates a valid suggestion that isn't empty.
The skip_empty_event_based_suggestion field is designed for features that generate suggestions asynchronously with event based triggers and delivers them through Pub/Sub. Features that don't rely on Pub/Sub for suggestion delivery, or are not event based, are not affected.
The skip_empty_event_based_suggestion field has the following two possible values.
- False: Agent Assist sends a Pub/Sub notification for every suggestion attempt. If Agent Assist doesn't find a suggestion for an event, you still receive a notification indicating an empty result.
- True: Agent Assist sends a Pub/Sub notification only if the suggestion result is valid and not empty. If Agent Assist doesn't find a suggestion, it doesn't publish a Pub/Sub message for that event, reducing noise in your notification topic.
Configuration
To suppress empty notifications, update your conversation profile and set skip_empty_event_based_suggestion to true as follows.
