list_aplus_content

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

The description only states the basic action without disclosing any behavioral traits such as pagination, rate limits, authentication requirements, or whether it lists all documents or only a subset. Given no annotations, this is insufficient.

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 short (one sentence) but lacks essential information. It is under-specified rather than optimally concise.

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 presence of an output schema and an optional parameter, the description fails to provide enough context for the agent to understand what the tool returns or how the parameter affects behavior. It is not complete enough for effective use.

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 description does not mention the 'marketplace' parameter at all, despite the schema having 0% description coverage. Agents cannot infer the meaning or usage of the parameter from the description.

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 'Listar' (list) and the resource 'documentos A+ Content' from the user's account. It distinguishes the tool from sibling 'get_aplus_content' by implying listing vs. retrieving a single document.

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 provided on when to use this tool versus alternatives like get_aplus_content or other listing tools. There is no mention of prerequisites, filtering, or when not to use it.

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