Multi-Channel AlertsAI Workflow

Broadcast notifications across Slack, email, and mobile push from a single event bus. Add or remove channels without touching business logic.

Prerequisites

Environment variables

SLACK_BOT_TOKENRESEND_KEYFCM_KEY

Install

$npx radzor@latest recipe add multi-channel-alerts

AI Prompt

“Run `npx radzor@latest add event-bus slack-bot email-send push-notification` to install 4 Radzor components. Then read components/radzor/event-bus/radzor.manifest.json, components/radzor/slack-bot/radzor.manifest.json, components/radzor/email-send/radzor.manifest.json, components/radzor/push-notification/radzor.manifest.json and each component's llm/integration.md. Wire them together to broadcast notifications across Slack, email, and mobile push from a single event bus. Add or remove channels without touching business logic. Use the manifest's inputs (check envVar for required environment variables), outputs (check fields for object shapes), composability (check mapField for field extraction), and actions — don't invent custom interfaces.”

LLM tip

Pass all 4 radzor.manifest.json files to your agent at once. It will read the outputs of each step and match them against the inputs of the next — wiring the full pipeline without any extra instructions.
