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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds the important behavioral caveat that the tool does NOT book anything by itself — the user must pick a slot in the link — which prevents the agent from falsely reporting a confirmed appointment. Return content (link + email) is also disclosed.

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?

Three short sentences: what it returns, when to use it, and the key behavioral caveat — in that order. No filler and the most decision-relevant information leads.

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 no parameters and no output schema, the description carries the burden of explaining return values and does so (

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 takes zero parameters, so there is nothing for the description to disambiguate; the baseline of 4 applies. The description correctly frames it as a no-input call whose output is a link and an email address.

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 concrete verb and resource: returns the scheduling link plus Miss Yera's email for a free 30-minute diagnostic. It is clearly a non-mutating link-provider, which distinguishes it from action tools in the sibling list. It stops short of naming the nearest sibling (pedir_contacto, cotizar_capacitacion) as an alternative, so differentiation is implied rather than explicit.

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?

Gives an explicit trigger set: when the user wants to contract, get a quote, request a proposal, or talk to her. That is clear context for invocation. However the 'cotizar/pedir propuesta' trigger overlaps with the sibling cotizar_capacitacion and no routing rule resolves that ambiguity.

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