Fill Out and Submit a Form, Including a Job Application

Capability: Vault credentials

Use this when the form itself needs real data — a name, an address, a resume field — and the site it’s on needs a login first. Put the login credentials in Vault, not in the goal text: the agent never sees the password, and it isn’t left sitting in your run history as plain text.

Connect your vault

Connect a supported password manager once. See Connect Your Vault for the setup flow.

Run the agent with vault access and the form goal together

from tinyfish import TinyFish

client = TinyFish()

run = client.agent.run(
    url="https://jobs.example.com/careers/senior-engineer",
    goal="""Log in, then apply to this job:
        - First name: "John"
        - Last name: "Doe"
        - Email: "john@example.com"
        - Upload the resume already on file for this profile
        - Answer "Are you authorized to work in this country?" with "Yes"
        Submit the application and return the confirmation number.
    """,
    use_vault=True,
)

print(run.result)

import { TinyFish } from "@tiny-fish/sdk";

const client = new TinyFish();

const run = await client.agent.run({
  url: "https://jobs.example.com/careers/senior-engineer",
  goal: `Log in, then apply to this job:
    - First name: "John"
    - Last name: "Doe"
    - Email: "john@example.com"
    - Upload the resume already on file for this profile
    - Answer "Are you authorized to work in this country?" with "Yes"
    Submit the application and return the confirmation number.
  `,
  use_vault: true,
});

console.log(run.result);

The agent logs in with the Vault-stored credential first, then works through the form fields in the goal. Nothing sensitive needs to appear in the goal text itself — only the form data that isn’t secret.

Output:

{
  "status": "COMPLETED",
  "result": {
    "success": true,
    "confirmation_number": "APP-2026-48213"
  }
}

Multi-Step Forms

A form that spans several pages — personal info, then details, then a review step — works the same way: describe every step in one goal, and the agent carries state across the whole flow.

Python

run = client.agent.run(
    url="https://jobs.example.com/careers/senior-engineer",
    goal="""Log in, then complete the multi-step application:

        Step 1 (Personal Info):
        - First name: "John"
        - Last name: "Doe"
        - Email: "john@example.com"
        - Click "Next"

        Step 2 (Experience):
        - Years of experience: "5"
        - Current title: "Software Engineer"
        - Click "Next"

        Step 3 (Review):
        - Confirm the details shown are correct
        - Click "Submit Application"

        Extract the confirmation number from the success page.
    """,
    use_vault=True,
)

Common Mistakes

Putting the password in the goal instead of Vault

Writing "log in with password XYZ" in the goal works, but the password then sits in plain text in your run history. Use use_vault: true with a connected credential instead — see Scrape Content Behind a Login Using Vault for the setup, same mechanism, different task.

Vague field instructions

“Fill in my info” doesn’t tell the agent what your info is. Spell out every field value explicitly, the same way the Goal Prompting Guide recommends for any task.
