Generate a ShadowTraffic configuration to populate a Kafka topic with realistic synthetic data. Discovers the target topic, its key and value schemas, and the correct serializers from the live cluster via any attached Kafka MCP server, then writes a ready-to-run `shadowtraffic-config.json` and Docker command. Use when the user says "populate my Kafka topic with test data", "set up ShadowTraffic for topic X", "generate synthetic events into my topic", "I need fake data flowing into Kafka", "seed my topic with data", or "mock data for my Kafka topic". Do NOT use for creating topics, reviewing schemas, or building Kafka consumers.

From the source SKILL.md

Generates a ShadowTraffic configuration that populates a Kafka topic with realistic synthetic data. The agent discovers everything — topic name, bootstrap servers, Schema Registry URL, key and value schemas and their serialization format — from the live cluster via whichever Kafka MCP server is attached. It then maps each schema field to the most semantically appropriate ShadowTraffic _gen function and writes a ready-to-run config alongside an exact Docker command.

What this skill does

Kafka Shadowtraffic is a community-contributed Claude Code skill in the data-engineering sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/kafka-shadowtraffic/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user says "populate my Kafka topic with test data", "set up ShadowTraffic for topic X", "generate synthetic events into my topic", "I need fake data flowing into Kafka", "seed my topic with data", or "mock data for my Kafka topic". Do NOT use for creating topics, reviewing schemas, or building Kafka consumers.
