GA4: Show data redaction

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the read-only safety profile is covered. The description does add useful scope: the settings apply only to web data streams, and it is explicitly the v1alpha surface, which signals potential API instability and that app streams are out of scope.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with zero filler; the resource and its scope come before the parenthetical detail. Nothing is repeated or padded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter read tool with full schema coverage and annotations covering safety, this is largely sufficient, and the parenthetical enumeration gives a rough idea of what comes back. There is no output schema, so the description could have said more about the returned structure (per-stream entries), which is the only real gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with both 'property' and 'dataStreamId' documented including a concrete example and the 'if omitted, all web streams' fallback. The description adds only the framing that redaction applies at stream level, which the schema already implies, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Shows') and a specific resource ('data redaction settings'), further qualified by the two setting categories (email addresses, URL parameters) and the scope ('web data streams of a property'). It does not name the write counterpart ga4_update_data_redaction, so sibling differentiation is left to the agent's inference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit statement of when to call this versus ga4_update_data_redaction or ga4_list_data_streams, and no prerequisites or permission notes. Usage is only implied by the word 'Shows', which suggests a read of existing configuration.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
