COMPUTER USE / USE CASE

Computer use for scheduled monitoring

Detect a meaningful portal change, preserve evidence, and notify only when the state is actionable.

Define the job

Check a defined dashboard or portal record on an agreed schedule, compare normalized observations with a prior accepted baseline, and produce an evidence-backed change event. Keep collection, comparison, and notification as distinct stages.

API FIRST?

Should this use computer use at all?

Prefer webhooks, feeds, or supported polling endpoints. Browser monitoring is a candidate for a relevant status that exists only in an approved interface.

Architecture options

Deterministic status monitor

Use a fixed browser flow and explicit extraction schema. Compare the resulting business fields rather than raw page HTML so timestamps and layout changes do not trigger meaningless alerts.

PlaywrightBrowserbase

Reviewed adaptive monitor

Evaluate an agent when the relevant status needs bounded interpretation. Route uncertain observations to review instead of replacing the baseline with a guessed value.

Failure modes & approval

Where the workflow can break

  • A login page or temporary error can be mistaken for a business status change.
  • The page may display cached or stale data despite a successful load.
  • Unbounded retries can increase access pressure and cost without improving evidence.

Human approval point

Approve the schedule, source scope, and notification destination. Any follow-up action beyond reporting a change requires its own authorization.
