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

Annotations already declare the tool as read-only, idempotent, and non-destructive. The description adds no behavioral context beyond what 'describe' naturally implies, such as any constraints, output details, or relationship to query tools. It does not contradict annotations but adds no extra transparency.

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, concise sentence that front-loads the action and lists the specific categories of information. Every word contributes meaning, with no redundancy or filler.

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 the tool has no parameters and an output schema exists, the description is largely complete. It names the specific resource and the types of metadata provided. However, it relies on the title to convey the dataset's subject ('share of plants using robots...'), so it is slightly less self-contained.

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 tool has zero parameters, so the baseline is 4. The description does not need to explain parameters, and the schema coverage is 100% (empty). The mention of what is described (filters, metrics, etc.) adds contextual value even though there are no parameters.

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's function: to describe valid filters, groupings, metrics, detail fields, and citation fields for the robotics.adoption dataset. It uses a specific verb ('Describe') and names the resource, distinguishing it from sibling describe tools for other datasets.

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 usage is implied: it is a describe tool paired with query_robotics_adoption_v1, meant to provide metadata before querying. However, the description does not explicitly say when to use it over alternatives or mention the companion query tool, so it only partially guides usage.

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