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

Annotations declare destructiveHint=false, readOnlyHint=false, openWorldHint=true, but the description does not explain whether existing files are overwritten in ruta_destino, how destination conflicts are handled, or what approval/confirmation entails. 'De forma segura' is vague and not backed by concrete behavior. It adds almost nothing beyond annotations for a mutation 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?

One efficient sentence, front-loaded with the action. It is very short but not wasteful; the problem is what it omits rather than verbosity.

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?

With 4 parameters at 0% schema description coverage, a nested object, no output schema, and a write operation, the description is insufficient. It does not document the expected shape of the 'imagen' object, the confirmation/approval flow, or what happens to an existing destination file.

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?

Schema description coverage is 0% for 4 parameters, including a nested 'imagen' object and optional 'confirmar'/'aprobacion_id'. The description mentions only the image format, adding no meaning to any parameter; a low-coverage schema demands compensation that is absent.

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?

Clear verb+resource: 'Descarga... una imagen... y la crea dentro de la carpeta autorizada', with supported formats (PNG, JPEG, WebP) and source (ChatGPT). It distinguishes itself from file siblings like crear_carpeta or mover_elemento. It does not explicitly differentiate from other write tools, but the niche (saving a ChatGPT image) is clear.

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 on when to use this versus alternatives, and no explanation of prerequisites such as the 'confirmar' or 'aprobacion_id' flow. For a write tool with confirmation parameters, the agent is left to infer when confirmation is required.

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