Find application defects and draft a reviewed fix

Why use this

1. A signup defect limited to a particular display size can escape checks on a developer’s usual screen. A proposed fix may hide the visible symptom while changing keyboard access, validation or behavior at other sizes.

2. A reproducibility and review plan could describe the affected state precisely and define what a fix must preserve. The engineering team would still need actual testing and code review before treating any pull request as a correction.

Why an agent / simpler alternative

Useful judgment

Turn UI observations into a focused defect hypothesis and identify related regression checks.

Simpler alternative

Use a known responsive-design test case when the failure is already isolated.

Unsuitable when

Testing requires production account actions or access beyond the approved environment.

Proposed inputs

1. Name

   Authorized application scope

   Owner

   Product owner

   Minimum scope

   Test environment, signup path and allowed nonproduction actions

   Quality check

   Confirm no real customer account or payment is needed.

2. Name

   Defect context

   Owner

   Developer

   Minimum scope

   Reported viewport, browser state and expected behavior

   Quality check

   Record exact steps and distinguish observation from suspected cause.

Access and setup — proposed or unknown

Proposed minimum

1. Supplied screenshots/reproduction notes and an offline test matrix before browser or code work.

Compatibility unknowns

1. Unknown: exact runtime, browser availability, application access and repository/test setup.

External actions requiring approval

1. Creating test accounts, changing code, posting PRs or deploying fixes.

Expected deliverable and review checks

Proposed artifact

Reproduction checklist and bounded fix-review proposal with regression scenarios.

Critical checks

1. The defect description identifies viewport, state and expected versus observed behavior.

2. A fix proposal does not imply that the original problem or regressions have been tested.

Missing output evidence

No new workflow run or output inspection was performed for this overlay.

Failure signals and proposed responses

1. Signal

   The proposed CSS hides validation text to remove overlap.

   Why it matters

   Visual improvement could conceal actionable form errors.

   Proposed response

   Require validation and accessibility review before considering the approach.

2. Signal

   The issue depends on zoom or a prior form state absent from the report.

   Why it matters

   The defect may be difficult to reproduce reliably.

   Proposed response

   Add the missing state to the reproduction questions.

Effort and cost — unknown

Setup work

1. Define safe test scope and a reproducible viewport/state matrix.

Ongoing review

1. Inspect the proposed diff and run authorized regression checks separately.

Unknowns

1. Unknown: defect cause, repair effort and cross-browser impact.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

An invented bug report gives screen width but omits zoom and validation state; a proposed fix hides error text.

Acceptance checks

1. Missing reproduction details are flagged.

2. The symptom-only fix is not labelled validated.

Stop conditions

1. Live signup, code changes or deployment authority is required.

Limits

1. Editorial defect plan; no reproduction, fix effectiveness or engineering validation is established.
