Run browser checks from direct Slack requests
Handle one off QA checks without leaving the conversation where they were requested.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Run Puppeteer Script
Tool to run a Puppeteer script and capture a screenshot. Use when automating headless browser tasks and needing a PNG output. Use after confirming the script logic.
Why this helps
Small browser checks get delayed when they require a separate handoff and setup.
- Keeps QA requests in context
- Speeds up one off checks
- Returns visual proof
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Customjs once.
- 2Create an automation named DM Browser Check.
- 3Tell Notis to validate the DM request, confirm the URL and safe script intent, then run Puppeteer and capture a screenshot.
- 4Pick Direct Message Received as the trigger and choose the report destination.
- 5Test with a low risk page and script.
Questions about this workflow
Can it run arbitrary scripts?
Use a prompt that limits execution to reviewed, task specific browser logic.
What if the DM lacks a URL?
The automation can ask for the missing URL instead of running.
