Transferencia atendida — iniciar

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

Annotations (readOnlyHint=false, destructiveHint=false) indicate mutation but not destruction. Description adds that the tool puts the call on hold, dials destination, and warns '⚠️ Real call', indicating actual phone interaction. No mention of failure modes or prerequisites, but sufficient for basic transparency.

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?

Two short sentences, no redundancy. The warning symbol adds emphasis without extra words. Each piece of information earns its place.

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?

Tool is simple (2 required params, no output schema) and description explains the basic flow. It could mention that this is the first step of a multi-step attended transfer process (use with complete/cancel), but overall it's adequate for a single-action tool.

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 coverage 0%: description mentions 'destination' in context ('marca a destination'), giving meaning to that parameter. However, 'callId' is not described at all. The description partially compensates for missing schema descriptions but not fully.

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?

Description clearly states the tool initiates an attended transfer: puts call on hold and dials destination to consult before completing. Uses specific verb 'inicia' and resource 'transferencia con consulta', distinguishing it from blind transfer and from the complete/cancel siblings.

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?

Description implies usage when wanting to consult before transferring, but does not explicitly state when not to use or provide alternatives like blind transfer. However, the context of attended transfer is clear and sibling tools exist for complete/cancel.

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