agent-news-summary

A scheduled AI-powered news digest bot that runs on Cloudflare Workers. Every morning it aggregates articles from configured sources, deduplicates them, summarises them with an LLM, and delivers a digest to Discord and/or WhatsApp.

How it works

1. A daily cron (default: 08:00 UTC) wakes the agent
2. New, unseen articles are collected from all configured sources
3. A Cloudflare Workers AI model produces a structured JSON digest
4. The digest is delivered to Discord and/or WhatsApp
5. Delivered articles are marked as seen (30-day retention) to avoid repeats

Tech stack

• Runtime: Cloudflare Workers + Durable Objects (SQLite state, scheduling)
• AI: Cloudflare Workers AI (@cf/moonshotai/kimi-k2.5 by default)
• Scraping: @cloudflare/puppeteer via Browser Rendering binding
• Sources: Hacker News API, RSS/Atom feeds, browser-rendered pages
• Delivery: Discord webhooks, WhatsApp Cloud API

Setup

Prerequisites: Node.js, a Cloudflare account with Workers AI, Browser Rendering, and Durable Objects enabled.

npm install

Configure secrets (at least one delivery channel required):

# Discord
wrangler secret put DISCORD_WEBHOOK_URL

# WhatsApp (all three required together)
wrangler secret put WHATSAPP_ACCESS_TOKEN
wrangler secret put WHATSAPP_PHONE_NUMBER_ID
wrangler secret put WHATSAPP_TO

Deploy:

npm run deploy

Development

npm run dev

Trigger a digest immediately without waiting for the cron:

curl -X POST http://localhost:8787/agents/source-digest-agent/default/trigger

npm test

Configuration

Edit wrangler.jsonc to change non-secret settings:

Variable	Default	Description
MODEL	@cf/moonshotai/kimi-k2.5	Workers AI model for summarisation
SCRAPE_CRON	0 8 * * *	Cron schedule (UTC)
SKIP_SEEN	"false"	Set to "true" to disable deduplication

Adding sources

Edit src/sources.ts. Three source types are supported:

• "hn-api" — Hacker News Firebase API
• "rss" — RSS 2.0 / Atom feed URL
• "browser" — Puppeteer-rendered page with heuristic article extraction
