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

The readOnlyHint annotation already declares this as a safe read operation, lowering the bar. The description adds content scope but no extra behavioral detail such as whether it returns contact information, hours, or pricing. It does not contradict the annotations.

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 short, well-formed sentence that front-loads the key topics. Every word earns its place with no clutter or repetition.

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 zero-parameter, no-output-schema informational tool, the description adequately covers what the agent can expect: company identity, location, and contact/booking actions. It is sufficient for safe invocation.

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 the baseline is 4. The description adds no parameter information, which is fine because there is nothing for the agent to configure.

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 what the tool covers: who 2ds is, where it works, and how to hire or book an appointment. This distinguishes it from siblings like preguntas_frecuentes (FAQs) and servicios (services), though it lacks an explicit verb like 'retrieve' or 'show'.

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 content scope implies when to use it (when a user asks about the company, location, or booking), but there is no explicit guidance about when not to use it or how it differs from solicitar_diagnostico, which might also involve appointments or contact.

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