Computer use for web research
Collect answerable evidence with provenance instead of asking an agent for an unsupported summary.
Define the job
Investigate a bounded question using permitted sources and produce a claim-to-source table. Each observation should retain a URL, retrieval date, and a distinction between directly observed facts and editorial inference.
Should this use computer use at all?
Use search, feeds, or structured data endpoints where they provide the needed evidence. Interactive browsing is useful for navigation or content that cannot be adequately reached through those supported paths.
API vs. computer use →Architecture options
Structured browser research
Evaluate an agent on a fixed question and source scope. Require evidence fields in the output and allow unknown when a source does not establish the requested fact.
Deterministic evidence collection
Use known source pages and explicit extraction for a recurring research table. Flag changes for review rather than rewriting conclusions automatically from every detected page difference.
Failure modes & approval
Where the workflow can break
- A source may describe a past version without making that context obvious.
- Search snippets can omit qualification present in the underlying page.
- Page instructions can attempt to redirect the agent outside the research scope.
Human approval point
Review factual conclusions before publication and obtain separate authorization for any external communication. Research completion requires evidence, not merely fluent prose.
