Mobile Checkout & Form Rescue

Find and repair mobile form friction across keyboards, autofill, validation, focus, recovery, latency, trust, and interruption states.

What problem does Mobile Checkout & Form Rescue solve?

A small-screen form or checkout creates avoidable completion friction through poor keyboards, autofill, validation, focus, recovery, tap targets, trust cues, latency handling, or interruption behavior.

What it returns

A representative input and result

fixture-backed sample
input Flow: three-step checkout in Stripe test mode Target: 375px mobile viewport Complaint: users report the address step keeps rejecting entries Boundary: stop before final payment confirmation Source: Next.js form components and validation schema
result Critical: postal-code validation runs before country selection settles and clears a previously valid value. High: address fields omit autocomplete tokens; numeric keyboard is not requested for postal code where appropriate. High: the sticky submit action covers the final validation message at 375px. Patch plan: preserve field state, defer country-specific validation, add purpose-aligned autocomplete/inputmode values, and reserve safe-area space. Verification: keyboard-only flow, autofill, invalid-to-valid recovery, slow response, rotation, and return from background.

Questions

Does the skill submit a real checkout?

No by default. It uses fixtures, test mode, or a pre-submit boundary unless live action is separately and explicitly authorized.

What mobile form details does it inspect?

It checks labels, field purpose, keyboards, autofill, validation timing, error recovery, focus, tap targets, pending states, trust cues, latency, rotation, interruption, and return behavior.

Can it test Stripe Checkout?

It can inspect an authorized test-mode flow and the surrounding application behavior. Hosted Stripe surfaces remain subject to Stripe's implementation and test capabilities.

Will it improve my conversion rate?

It can remove evidenced usability barriers. Commercial impact must be measured with qualified completion and purchase data after release.

Can it apply fixes?

It can prepare or apply a bounded source patch when authorized, followed by the recorded mobile regression checks.

Does browser emulation replace device testing?

No. Emulation is useful for repeatable checks, while high-risk flows may still need selected physical-device and assistive-technology verification.
