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

No annotations are provided, so the description carries the full burden. It does disclose the nature of the content returned (site scale and channel map) and implies a read-only, zero-side-effect call, but says nothing about the structure of the output or how sections are enumerated. Adequate but thin for an unannotated tool.

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?

Two short sentences with no filler: the resource identity and content come first, then the routing guidance. Every clause earns its place and the reader can stop after the first sentence if they only need to know what the tool does.

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 parameterless, annotation-free tool with no output schema, the description supplies both the purpose and a usable sketch of the return value (scale + section map), which is what an agent needs to decide to call it. Only the concrete shape of the overview content is left implicit.

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 takes zero parameters, which is the baseline-4 case: there is nothing for the description to disambiguate, and the empty schema is self-explanatory. No additional parameter meaning is needed.

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?

Names a specific resource (site overview of wjorg.com) and states exactly what it returns: the site's scale and a map of its sections/columns. This distinguishes it from the operational siblings (search_articles, run_calculator, get_law_article), which all act on content rather than describing the site itself. It stops short of a crisp single verb, but the reader knows precisely what the tool produces.

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?

Gives explicit triggering conditions: when the user asks 'what do you have' or 'what can you help me do', and whenever the agent needs to decide which tool to route to, call this first. That is clear context for use. It does not state an exclusion case or name a specific alternative to avoid, so it falls short of the 5 bar.

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