analytics_range_categories_top

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

Annotations already indicate readOnlyHint and openWorldHint, so the description gains limited credit. It does not explain what 'top' means (e.g., by count or amount) or mention any other behavioral traits like response size or sorting, beyond the implicit read-only operation.

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 concise with three sentences covering purpose, usage, and trigger words. However, the trigger words section is somewhat redundant and could be merged, and the structure is front-loaded but not optimized for quick scanning.

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?

Given no output schema, the description should explain return values but does not. It also misses details on optional parameters and the meaning of 'top'. With many sibling tools, the description provides adequate context for selection but falls short on invocation completeness.

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 coverage is 0%, so the description should compensate. It mentions date range for startDate and endDate but provides no information on optional parameters (paymentMethod, account, limit). The default value for limit is not explained, leaving the agent guessing.

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 tool gets top categories for a date range, distinguishing it from sibling tools like analytics_range_categories (which likely returns all categories) and period-based tools. The trigger words further clarify the purpose.

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 'When to use' section explicitly guides usage for top-N category questions over a custom date range and provides trigger words. However, it lacks explicit exclusions or alternatives (e.g., when to use a period-based tool instead).

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