SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build, validate, serialize, or parse CNCF CloudEvents v1.0 payloads to ensure agents produce spec-compliant event envelopes across transports like HTTP structured, HTTP binary, and Kafka bindings.

Core Features & Use Cases

Build spec-compliant CloudEvent payloads for CloudEvents v1.0 across HTTP structured, HTTP binary, and Kafka bindings.
Validate, serialize, and parse CloudEvents, enforcing required attributes, extension naming rules, and mutual exclusivity of data and data_base64.
Use cases include event-driven microservices, telemetry pipelines, and cross-transport interoperability requiring precise event envelopes.

Quick Start

Install the skill and run the validator to verify CloudEvents conformance in your codebase.

FAQPage Schema

How do I validate a CloudEvents v1.0 payload for spec compliance?▼

Validate CloudEvents v1.0 payloads by enforcing required attributes like non-empty id, source, and type, alongside specversion '1.0' as a string. The validator also checks RFC3339 time formats, extension naming rules, and a 64 KB wire size guard.

How does CloudEvents serialization work across HTTP and Kafka bindings?▼

CloudEvents serialization applies to HTTP structured, HTTP binary, and Kafka bindings, enabling end-to-end event creation and parsing across microservices. It enforces mutual exclusivity of data and data_base64 to maintain payload integrity across transports.

What are the required attributes for a compliant CloudEvents v1.0 envelope?▼

A compliant CloudEvents v1.0 envelope requires specversion '1.0' as a string, non-empty id, source, and type attributes. When present, time must follow RFC3339, and extension names must be lowercase alphanumeric with a maximum of 20 characters.

Can I use CloudEvents for event-driven microservices and telemetry pipelines?▼

CloudEvents is designed for event-driven microservices, telemetry pipelines, and cross-transport interoperability. It ensures precise event envelopes across HTTP structured, HTTP binary, and Kafka bindings for reliable microservice communication.

Why does my CloudEvents payload fail validation when both data and data_base64 are present?▼

CloudEvents validation enforces mutual exclusivity of data and data_base64 fields. Specifying both violates the CloudEvents v1.0 spec, causing validation failures to ensure unambiguous payload decoding across HTTP and Kafka transports.

What is the maximum wire size limit for a CloudEvents payload?▼

The maximum wire size limit for a CloudEvents payload is 64 KB. This guard ensures payloads remain within acceptable size constraints for reliable transmission across HTTP structured, HTTP binary, and Kafka bindings.
