What this tool does

Scope and expected outcome.

Page-size checks remain deferred pending network/request policy. Execution remains Deferred.

Tool deep dive

Performance tools

Input

Required input

A public URL to inspect, plus an optional depth or comparison target where supported.

Output

Expected output

A page weight summary with bytes transferred and loaded asset posture.

Network

Provider and network requirements

These tools need governed outbound network access to fetch public pages or DNS/TLS data, but no new provider integration is enabled in this pass.

Controls

Abuse controls before activation

Activation needs fetch caps, host validation, and retry limits to avoid abusive crawl patterns.

Privacy

Privacy posture

No durable storage is introduced; request metadata is only used for transient processing and abuse protection.

Status

Why execution is not active yet

Execution remains deferred until the governing source-policy, provider, or legal controls are approved.

Common use cases

Typical scenarios this tool supports.
