Fill Multi Step Form
Fills a multi-step form (stepper wizard) by routing labeled fields to values from `vars`, clicking "Next" between steps, and submitting at the end. Pairs with the `searchable-dropdown` and `date-picker-widget` skills for compound widgets.

Fill Multi-Step Form
When to invoke
The page has a form spread across multiple steps (Typeform, Calendly, hotel checkout, multi-page job applications, etc.). The agent has the values to fill in vars keyed by either field-name, field-id, or label text.
The matcher runs this skill when the DOM has a ` plus any step-indicator marker. Without step-indicators, the simpler single-step form pattern (fill` primitive calls authored by the agent directly) usually suffices.
Recipe
- waitfordom_ready timeout=5s
- waitforselector selector="form, [role='form']" state=visible timeout=5s
- fill selector="input[name='name'], input[id*='name' i][type='text']" value="$vars.name"
- fill selector="input[type='email'], input[name*='email' i]" value="$vars.email"
- click selector="button:has-text('Next'), button:has-text('Continue'), button[type='submit']" timeout=2s
- wait extra=400ms
Success criteria
- assert novisibleelement selector="[role='alert'][aria-invalid='true']"
- assert stepindicatoradvanced
Notes
The recipe above is the minimum-viable scaffolding. Real forms vary widely; agents are expected to compose fill primitives directly when the field set is fully known up front. This skill is most useful when:
- The field set is partially unknown until later steps render
- Validation errors must be detected and recovered (handled by the
agent on failed return)
When NOT to use
- Login forms — use
login-flow. - Forms inside a captcha-protected flow —
detect-captchafirst.
Known failures
- Hidden fields with same name as visible fields: the selector
picks the wrong one. Workaround: use an id selector instead.
- Steps that conditionally show fields based on earlier answers:
v0.1 doesn't handle dynamic form structure. Agent must invoke the skill once per step.
- Drag-and-drop fields, signature widgets: out of scope.
