What is Pilot Event Filter?
Pilot Event Filter is a powerful utility within the Openclaw Skills ecosystem designed for fine-grained control over event streams. It allows developers to go beyond simple topic wildcards by implementing deep content inspection and payload transformation before delivery.
By leveraging the industry-standard jq processor, this skill enables conditional routing and noise reduction in complex multi-agent environments. It is an essential component for building responsive, efficient, and decoupled systems where data precision is paramount.
Pilot Event Filter Use Cases
- Filtering high-volume event streams by specific content attributes rather than just topic names.
- Transforming event payloads on-the-fly to ensure compatibility between different system components.
- Implementing conditional routing logic to direct critical events to specific destinations.
- Reducing event noise by selectively forwarding only the data that meets strict criteria.
How Pilot Event Filter Works
- The skill establishes a connection to the event stream by subscribing to a source hostname and topic via the pilotctl utility.
- Incoming JSON event data is piped into jq, where user-defined filter or transformation expressions are applied.
- The filtered data is validated against specific logic (such as severity levels or data types).
- Processed events are either consumed locally or republished to new destinations and topics for downstream processing.
Pilot Event Filter Setup
To use this skill, ensure you have the pilot-protocol skill installed and the pilotctl binary available in your PATH. The daemon must be active.
# Start the pilot daemon
pilotctl daemon start
# Ensure jq is installed for transformations
sudo apt-get install jq # Linux
brew install jq # macOS
Pilot Event Filter Data Schema & Taxonomy
The skill processes JSON-formatted event packets and organizes data based on the following structure:
| Attribute | Description |
|---|---|
source-hostname |
The origin point of the event stream. |
topic |
The primary categorization label for the event. |
filter-expression |
The jq-based logic used to include or exclude specific events. |
transform-expression |
The jq-based logic used to modify the event payload. |
payload |
The actual data content within the event, often nested in .data.events[]. |
Pilot Event Filter Advanced Features
- Complex pattern matching using full jq expression syntax for deep JSON inspection.
- Automated republishing loops to facilitate agent-to-agent relaying and transformation.
- Time-bounded subscriptions using the --timeout flag for controlled resource management.
- Seamless integration with the broader Openclaw Skills suite for multi-agent orchestration.
