A browser action.
A result you can check.

The problem was coordination.

When work happens inside a browser, an action can be interrupted by a page change, a reload, or another worker. A click alone does not establish that the intended result occurred.

I built a screening workflow extension around those uncertainties. The design separates ownership of a task from the act of operating the page, so the next step depends on what can actually be confirmed.

Make the state explicit.

Claim before acting

A worker requests ownership of the task through a central coordination interface before carrying out the action.

Confirm the visible result

The extension checks for evidence on the page before treating the action as complete. A pending result remains pending.

Quarantine uncertainty

If the result cannot be established, the item is held for review. An ambiguous action is not automatically treated as a safe retry.

Recover after interruption

Pending state and reconciliation give the operator a way to recover after a reload without discarding the history of the attempt.

What was checked.

Source tests covered the extension’s claim, confirmation, quarantine, and recovery behavior. The implementation also included deterministic initial copy and operator alerts when delivery could not be established.

The evidence available for this case is the implemented extension and its source tests. It does not establish the live state of the corresponding central backend or a measured business improvement.

A clearer operating model.

The implemented result is a browser worker with explicit states for owned, pending, confirmed, and uncertain work. That makes the design reviewable and gives operators a defined response when an action is unclear.

The broader lesson is useful beyond one browser surface: reliable automation needs a definition of completion, a record of ownership, and a recovery path. Browser interfaces can change, so these systems also need ongoing compatibility checks.
