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

The annotations already declare this read-only and non-destructive, so the description is not responsible for that burden. It adds helpful context about what metrics are included, but does not disclose operational behavior such as exact units, time ranges, or any limitations. There is no contradiction with the annotations.

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 first sentence is tight and informative, front-loading the key metrics. The second sentence is largely tone-setting and could be trimmed, but it does not create real noise. Overall the description is short and readable.

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 zero-parameter read-only tool, the description supplies enough to know what the call returns: visitors, page views, and click-throughs. Precise units and response shape are not specified, but with no output schema and only this scope, that is a minor 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?

There are zero parameters, so the input schema carries no burden and the description does not need to explain parameter meaning. The description's metric list adds useful output expectations beyond the empty schema, which keeps this above the baseline.

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 identifies a specific deliverable — the board's public traffic numbers — and spells out the concrete metrics: visitors, page views, and click-throughs to brands. This clearly distinguishes it from sibling tools like get_board and get_brand_stats, which concern different aspects of the board. The title reinforces the same resource and scope.

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 wording strongly implies this tool is for board-level traffic metrics rather than brand-specific or board-detail queries, but it never explicitly states when to prefer it over get_brand_stats or get_board. The context is clear enough to infer the use case, but it stops short of naming alternatives or exclusions.

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