Auth

Log into the local Carbon ERP dev server with agent-browser using the DEV_BYPASS_EMAIL bypass. Use before any browser automation that needs an authenticated session (/test, /smoke-test, manual verification). Requires a running dev stack (crbn up). Building block — it leaves the session open for the caller.

auth — authenticate the local browser session

Authenticate against the local Carbon dev environment via DEV_BYPASS_EMAIL. Other skills (/test, /smoke-test) invoke this before authenticated work.

Prerequisites

Dev server running (crbn up; plain pnpm dev also works)
DEV_BYPASS_EMAIL=test@carbon.ms in .env.local and the test@carbon.ms user seeded — both are done automatically by crbn up

Steps

1. Resolve the ERP URL

grep '^ERP_URL' .env.local

The value varies per worktree — always read it; never assume a URL or port.

2. Open the login page

agent-browser open ${ERP_URL}/login && agent-browser wait --load networkidle && agent-browser snapshot -i

(If wait --load networkidle times out — dev HMR keeps sockets open — use sleep 3 then agent-browser snapshot -i instead.)

3. Fill the email and submit

From the snapshot, find the email input ref and the sign-in button ref:

agent-browser fill @eN "test@carbon.ms"
agent-browser click @eM && agent-browser wait --load networkidle

4. Verify — do not assume

agent-browser snapshot -i

redirected to /x (the authenticated dashboard), and
shows a greeting ("Good morning, Test" / "Good afternoon, Test") and module cards.

If the snapshot shows "Authentication Error" or is still on /login → login failed. STOP and report the snapshot content; do not retry blindly.

Output

The browser session is authenticated; subsequent agent-browser commands carry the auth cookies. Do not run agent-browser close — leave the session open for the caller.

MES

The MES app is a separate URL: read MES_URL from .env.local and navigate there. The same cookies apply — no separate login.
