Paste this into your coding agent

After onboarding, run this from your app's repository. The agent runs the CLI and reads the result; a person approves the browser sign-in.

This repository uses Zerocheck for browser tests, and our zerocheck.yaml and YAML tests are already in place. If zerocheck is not installed, run `npm install --save-dev --save-exact zerocheck`, then `npx playwright install chromium`. Ask me for our instance URL, set it as ZEROCHECK_API, and ask me to approve `npx zerocheck login` in my browser. Then run `npx zerocheck run --json .zerocheck/latest-run.json`. Report the exit code, each test's result and the Results link. If a test fails, investigate it without changing its expected outcome, and ask me before you edit a test.

Agent quickstart

Requires your instance URL, zerocheck.yaml, saved YAML tests and a running app, set up during onboarding. Read the complete quickstart.

npm install --save-dev --save-exact zerocheck
npx playwright install chromium
export ZEROCHECK_API="https://your-instance.example.com"
npx zerocheck login
npx zerocheck run --env dev --json .zerocheck/latest-run.json
