List report pages

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds nothing beyond that: no pagination behavior, no note on what happens with an invalid report_id, no indication of who may read a report. It essentially restates the title.

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?

One short sentence with zero filler and the key resource front-loaded. It is efficient, though its brevity edges into under-specification rather than tight writing.

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 simple read-only list operation with a single fully-described parameter, the description covers the essentials. Because there is no output schema, an agent still lacks any hint about the shape or size of the returned page list, and there is no mention of pagination, leaving a modest 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?

The single parameter is fully documented in the schema itself ('Report id or any URL of the report'), and schema coverage is 100%, so the baseline is 3. The description contributes no additional parameter meaning, such as accepted URL formats or whether IDs are scoped to a workspace.

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?

The description gives a clear verb+resource ('List the pages of a Looker Studio report'), so it is unambiguous about what it returns. It does not, however, differentiate itself from siblings like list_reports or list_components, which also enumerate report-related entities.

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 guidance about when to use this tool versus list_reports, list_components, or describe_component, nor any stated prerequisite (e.g. that a report_id must first be obtained). The only implied usage comes from the required parameter.

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