RSS Digest Summarizer

Poll any RSS/Atom feed for new articles, summarize each with AI, and post a curated digest to a Slack channel automatically.

RSS Digest Summarizer is an automation that polls any RSS or Atom feed for new articles, uses OpenAI to summarise each item, and delivers a clean digest report to a Slack channel on a configurable schedule.

What it does

• RSS monitoring: Polls any RSS/Atom feed for new articles with rss-digest (every 3 minutes by default)
• AI summarisation: Passes each article through OpenAI (gpt-4o-mini) for a concise summary via summarize-content
• Slack delivery: Formats all summaries into a rich Slack message and posts it to a channel via send-digest

Environment variables (.env / keyring on apps)

Variable	Purpose
HABITS_OPENAI_API_KEY	OpenAI API key for content summarisation
HABITS_SLACK_BOT_TOKEN	Slack Bot User OAuth Token (xoxb-...)
HABITS_SLACK_DIGEST_CHANNEL	Slack channel ID to post the digest to
HABITS_RSS_FEED_URL	RSS/Atom feed URL to monitor for new articles

How to set up

1. Copy .env.example to .env and fill in your credentials.
2. Set any RSS/Atom feed URL in HABITS_RSS_FEED_URL.
3. Create a Slack app, add chat:write and channels:read bot scopes, install it to your workspace, and copy the xoxb- token.
4. Invite the bot to your target channel and copy the Channel ID into HABITS_SLACK_DIGEST_CHANNEL.
5. Click Start Automation in the UI — articles will be discovered, summarized, and posted to Slack every 3 minutes.

Run Serverless

For serverless or containerized deployments, we recommend using Docker:

# Using Docker (recommended for serverless)
docker run -p 3000:3000 -v $(pwd)/your-app.habit:/app/habit.habit \
  node:20-alpine npx @ha-bits/cortex --config /app/habit.habit --host 0.0.0.0

Or create a Dockerfile:

FROM node:20-alpine
WORKDIR /app
COPY your-app.habit ./
COPY .env ./ # Optional: include environment variables
RUN npm install -g @ha-bits/cortex
EXPOSE 3000
CMD ["cortex", "--config", "./your-app.habit", "--host", "0.0.0.0"]

• [ ] Create a Dockerfile or use the Docker run command above
• [ ] Deploy to your preferred cloud provider (AWS, GCP, Azure, etc.)
• [ ] Configure environment variables via your cloud provider's secrets management
• [ ] Set up health checks at /habits/base/api endpoint
