get_stats

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

No annotations are provided. The description identifies it as a 'get' operation, implying it is read-only and non-destructive, but it does not disclose any other behavioral traits such as permissions, rate limits, or data freshness. The description is adequate but not rich.

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 that is concise and front-loaded with the verb and resource. Every word contributes to clarity, with no unnecessary 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?

For a no-parameter tool with no output schema, the description provides a reasonable list of statistics categories. However, it lacks details on the output structure or format, which would be helpful for an agent to interpret the results. Nonetheless, it is largely complete for the tool's purpose.

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 zero parameters, so the description does not need to add parameter meaning. According to the rubric, 0 parameters gives a baseline of 4. The description lists the statistics categories, which are the output rather than input, but it does not detract.

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' and the resource 'task statistics', and lists specific categories of statistics (totals, completed today, due today, overdue, by project). This distinguishes it from sibling tools like get_task (single task) or list_tasks (listing tasks) and provides a clear 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 description does not explicitly state when to use this tool versus alternatives like list_tasks or get_task. It implies that statistics are aggregated rather than individual tasks, but no direct guidance or exclusions are provided.

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