auth_skill

Overview

This skill guides Claude through interactive website authentication flows using the browse CLI. It provides step-by-step checks, user prompts, and commands to detect login pages, submit credentials, handle MFA, and verify success.

How this skill works

After navigating to a page, the skill inspects snapshots for login indicators (password/email inputs, OAuth buttons, sign-in text). It prompts the user for credentials or 2FA codes when required, then issues browse CLI commands to fill fields and click buttons. The skill verifies authentication by waiting for navigation, checking for profile elements or absence of error messages, and suggests fallback options if login fails.

When to use it

• A website requires login or shows an authentication wall.
• Session cookies have expired and a fresh sign-in is needed.
• Tasks require access behind a user account or dashboard.
• You encounter OAuth, SSO, passwordless, or 2FA flows.

Best practices

• Always ask the user for credentials; never assume or store them.
• Use browse snapshot to locate accurate form refs before filling.
• Prompt users clearly for 2FA codes or to click magic links in email.
• Avoid attempting to solve CAPTCHAs automatically; present alternatives.
• Clear sensitive input from the conversation after the flow completes.

Example use cases

• Log into a news site to retrieve an article hidden behind a paywall.
• Authenticate to a web dashboard to perform account-specific actions.
• Follow an OAuth flow (Google/GitHub) by clicking the provider button and awaiting redirect.
• Complete a passwordless login by entering an email and confirming the magic link.
• Handle a 2FA prompt by asking the user for the authenticator or SMS code and submitting it.
