get_gmvmax_range_report_tool

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

No annotations are provided, so the description carries the full burden. It discloses that the tool returns an aggregate report with specific fields and notes the absence of timezone alignment, but does not detail other behaviors such as read-only status, authentication requirements, or rate limits.

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 sentence with a supplementary note on return fields. It is highly concise, front-loads the key purpose, and contains no extraneous information.

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?

The tool has four required parameters with no schema descriptions, no annotations, but has an output schema. The description explains what is returned and the timezone caveat, but lacks details on parameter formats, prerequisites, or context about 'GMVMAX'. It is adequate but not comprehensive.

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 input schema has 0% description coverage, meaning no parameter descriptions. The description mentions 'date range' which loosely relates to start_date and end_date parameters, but provides no format, constraints, or examples for any parameter. Thus, it adds minimal additional meaning beyond the parameter names.

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 clearly states the verb 'Get', the resource 'GMVMAX aggregate report', and specifies the date range. It explicitly mentions 'no timezone alignment', distinguishing it from the sibling tool 'get_gmvmax_report_aligned_tool', which likely provides timezone alignment.

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 description provides clear usage context by indicating the report is for a date range and lacks timezone alignment, implying it should be used when timezone alignment is not needed. However, it does not explicitly state when not to use it or mention alternatives.

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