ga4_batch_run_reports

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

With no annotations provided, the description carries the full burden and does disclose important traits: the operation is read-only, reports are independent, and they are executed as one batch request. It does not address what happens on partial failure, per-report quota behavior, or how the batch response is ordered, which are meaningful for a batch endpoint.

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?

The description is a single dense, front-loaded sentence with no redundant wording. Every element — count, read-only nature, report type, property scope, and batch mechanism — earns its place.

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 complex nested batch tool with no annotations and no output schema, a one-sentence description is thin. It omits usage routing, response shape/order, and batch failure semantics; only the fairly detailed input schema prevents this from being fully inadequate.

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 only 50%, and the top-level `reports` parameter has no description in the schema. The tool description adds that there are 1-5 independent GA4 Core reports for the same property, but it does not help an agent understand report object composition, required metrics, or the propertyId format beyond what the schema already states.

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 names a specific action ('Run'), a concrete resource ('GA4 Core reports'), and clear scoping ('1-5', 'same property', 'one official Data API batch request'). This clearly distinguishes it from single-report and pivot-report siblings without requiring the reader to open the schema.

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?

The count constraint '1-5' and the word 'batch' imply this is for bundling multiple independent reports, which gives useful context. However, it does not explicitly say when to prefer this over ga4_run_report or ga4_batch_run_pivot_reports, nor does it state exclusions.

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