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

No annotations are provided, so the description carries the full burden of disclosing behavior. It only identifies a data domain and does not state whether this is read-only, what data is returned, whether results are paginated, or whether any authentication or scoping applies. The description does not contradict any annotations because there are none.

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 extremely compact, with no filler words, and the English parenthetical clarifies the Portuguese noun. Its brevity is appropriate for a zero-parameter list tool, though the undefined 'catálogo tocável' term keeps it from being perfect.

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?

Invocation is trivial because there are no parameters, but the description does not explain what the returned networks look like or what 'catálogo tocável' means, and there is no output schema or annotations to compensate. An agent can call it blindly but cannot anticipate the response shape or judge whether its result is what the user wants.

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 there is no parameter semantics for the description to clarify. The baseline for a no-parameter tool is 4, and the description correctly requires no input details.

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 the resource ('networks') and scopes it to 'the touchable catalog', so an agent can tell it is a list-type tool. However, it never states an explicit verb, and the term 'catálogo tocável' is unexplained jargon, so it does not fully differentiate it from the other list_* siblings beyond the noun.

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?

No guidance is given about when to use this tool versus alternatives such as list_cities, list_countries, or list_tags. There are no explicit exclusions, conditions, or cross-references, leaving the agent to infer usage context from the name alone.

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