crear_dispositivo

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

With no annotations present, the description carries the full burden, and it excels: it reveals that Packet Tracer silently fails (no creation and no error) if the model name doesn't match, describes auto-positioning by type, requires unique names, and clarifies that the tool only places an icon with no connectivity. These are high-value, non-obvious behaviors that annotations could not have supplied.

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 long, but nearly every line earns its place given the tool's complexity: a large valid-catalog list, positioning rules, naming constraint, and two critical prerequisites. It is well organized with headers, bullets, and a bolded IMPORTANTE section, and it front-loads the purpose. The only minor redundancy is that the catalog partially overlaps the input-schema enum.

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 tool with 4 parameters, 0% schema description coverage, no annotations, and an output schema, the description is remarkably complete: it defines valid inputs, exact-match failure semantics, optional coordinate behavior, naming uniqueness, and the required follow-up actions (conectar_dispositivos, agregar_modulo_router). Nothing an agent needs to invoke it correctly is missing.

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%, and the description fully compensates for all four parameters: modelo is explained via the organized catalog plus the exact-match rule, x/y are documented as optional with type-dependent auto-positioning, and nombre is constrained to be unique in the topology. It adds substantial semantics that the bare schema (types and an enum) does not convey.

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?

States a clear verb-resource pair: 'Crea un dispositivo de red en Cisco Packet Tracer'. The description also explicitly distinguishes this tool from its siblings by declaring that it 'solo coloca el icono en el canvas' and that connectivity is handled by a separate tool, so an agent can tell it apart from conectar_dispositivos or configurar_dispositivo.

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?

The description gives an explicit workflow: create all devices first, then call conectar_dispositivos(), and call agregar_modulo_router for WAN serial modules before cabling. It also states when the tool is not sufficient (no connectivity without cables). However, it does not contrast against similar creation-like siblings such as crear_router_maestro, leaving a small ambiguity.

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