How the habit works.
You don't have to.
When does it start? How does it check its work? What does it remember?
One run, step by step.
Then it stops.
Stops after 10 scripts and one retry per run.
- 01
Set up once
Your agent runs npm run setup in the skill folder to install Playwright and Chromium.
- 02
Find the server
It runs detectDevServers and uses the single result, or asks you.
- 03
Run saved scripts
It runs each script with node run.js, keeping them in PW_SCRIPT_DIR.
- 04
Check responsive views
It takes desktop and mobile screenshots into PW_ARTIFACT_DIR.
- 05
Check the page
It verifies the resulting page before calling a step passed.
- 06
Report
It logs actions, failures and artifact paths.
What it may do.
Nothing more.
It writes only in its own folder and asks you before anything goes out.
- Writes only inplaywright-tests/**, playwright-artifacts/**, loops/playwright-site-check-loop/**
- Talks tolocalhost
- Sendsnothing
- Your OKNothing goes out, so it needs no OK.
