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

With no annotations, the description carries the behavioral disclosure burden. It gives a fair idea of the output contents, but leaves 'coverage dates' vague and does not explain the response format. The tool is simple and read-only by nature, so this level is minimally viable.

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 compact sentence with no filler. It is slightly telegraphic, but every phrase maps to a distinct piece of useful 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 zero-parameter, stateless info tool, the description is mostly sufficient: an agent can infer the call needs no input. However, the absence of any usage context or output-shape hints leaves minor ambiguity around what 'coverage dates' means and how the result is presented.

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 has no need to explain parameter meaning, and it does not clutter the definition with irrelevant detail.

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 names three concrete outputs: tool count, coverage dates, and an explanation of what WireTensors is. This clearly distinguishes it from sibling tools like search_tools or compare_tools, though it lacks an explicit verb such as 'returns' or 'provides'.

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?

There is no guidance about when to use this tool versus alternatives. The sibling context shows related tools, but the description never says 'use this for site-level metadata' or 'use get_tool for specific tool details'.

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