Guide / signup troubleshooting

Why your coding agent cannot create an account, and how to unblock it

Most account-creation failures come from a missing browser identity, verification path, human decision, or credential handoff, not from the model being unable to click a button.

01

Short answer

Give the agent a real browser it can observe, a user-approved identity session, a way to complete email verification, and a precise definition of the finished outcome. Then separate retryable page errors from gates that require you.

Do not hand the agent your primary password or assume that account created means the job is done. Developer setup often continues through project creation, callback URLs, API key generation, and secure storage.

  • The agent can open and inspect the provider's current signup page.
  • Google, GitHub, or email verification is available through an approved path.
  • The requested account, project, region, and credential outcome are explicit.
  • The workflow knows when to pause for phone, payment, CAPTCHA, or account choice.

Action plan

  1. 01

    Name the final artifact

    Ask for the account plus the project, integration, or API credential your code needs. This prevents a shallow stop at the welcome page.

  2. 02

    Connect identity in a real browser

    Sign into Google or GitHub yourself in the browser profile the agent will use. Do not paste the identity password into chat.

  3. 03

    Provide a verification route

    Use an inbox workflow for expected signup links or codes, with explicit consent and a human fallback for ambiguous messages.

  4. 04

    Classify the gate

    Distinguish a changed page, expired link, duplicate account, provider rejection, human challenge, and missing product decision before retrying.

  5. 05

    Capture the usable result

    Finish project configuration and store any generated credential outside the agent conversation or repository.

What to know

The browser is part of the identity boundary

A coding agent can reason about a form but still lack the authenticated session needed to submit it. OAuth redirects, account selectors, device checks, and cookie state belong to a browser profile. A separate unauthenticated automation context may look like a new device every run.

Connect identity where you can see the real provider page. The agent can then operate the resulting session without learning your Google or GitHub password.

Verification needs a narrow contract

Email verification is not one generic task. A message can contain several links, codes, marketing buttons, and account notices. The workflow should expect a sender and purpose, extract only the relevant code or link, and stop when the message is ambiguous.

Phone verification is a different boundary. If a site requires a personal number or device action, hand it to the account owner rather than inventing an identity workaround.

Define success past the signup screen

For a developer, the useful result may be a configured provider project, a verified domain, an OAuth client, or an API key. Write that endpoint into the request so the agent knows which post-signup steps are still part of the job.

  • Account exists under the intended identity.
  • The correct organization, project, and environment are selected.
  • Required callback URLs, domains, or webhooks are configured.
  • The generated credential is stored and named for later use.

Where Trusty Squire fits

Trusty Squire supplies the browser and credential pieces that ordinary coding agents lack. It can open the real signup site, use a Google or GitHub session the user connects, handle available email verification, and continue through authenticated setup.

The coding agent remains responsible for the development goal and each next-step decision. Trusty Squire performs the scoped website action and can save a generated credential directly rather than returning it through credential tools.

Limits to keep in view
  • A site can require payment, phone verification, CAPTCHA, or a choice that belongs to the user.
  • Not every changed website flow has a replayable skill, so the agent may need to observe and drive it fresh.
  • Successful account creation does not prove that the requested project or integration is configured correctly.

Install Trusty Squire when the missing piece is the website work or a credential boundary for your coding agent.

Frequently asked questions

Why can my coding agent fill a form but not finish signup?
The missing step is often browser identity, email or phone verification, a CAPTCHA, account selection, or post-signup configuration. Form filling alone does not satisfy those contracts.
Should I give the agent my Google password?
No. Sign in on the real Google page inside the browser profile the workflow uses. The browser can retain the resulting session without putting your password in the prompt.
Can an agent automatically click every verification link?
It should only follow an expected link for the requested signup and sender. Ambiguous messages, security alerts, password resets, and unrelated links need a human decision.
What is a good signup prompt?
Name the service and the usable outcome, for example: create the account, create a project named Acme staging, generate its API key, and store the key under a specific credential name.
