createScheduledCall

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

With no annotations, the description carries behavioral disclosure. It reveals an important non-obvious behavior: the scheduled call only activates if status is set to LIVE. But it does not explain how to set that status or what happens before activation, and it omits other side effects or authorization requirements.

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 short and front-loaded with the primary purpose. The second sentence earns its place by conveying the activation requirement, though its wording is terse and somewhat cryptic.

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 create operation with no annotations and no output schema, this description is incomplete: the activation mechanism (setting status LIVE) is not represented in the input schema, the response is unspecified, and one parameter (receipient_name) lacks a schema description. An agent cannot confidently complete the full scheduling workflow from this text.

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 83%, so the schema already documents most parameters. The description adds no parameter-level detail and its reference to 'status LIVE' could imply a status parameter that does not exist in the schema, which slightly weakens the otherwise adequate baseline.

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 a specific action and resource: 'Schedule an outbound call.' This distinguishes it from instant-call siblings such as makeInstantCall and quickCall, though it does not name them explicitly.

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 word 'Schedule' implies this tool is for future-dated calls rather than immediate ones, and the LIVE-activation note implies a workflow step. However, the description does not explicitly state when to prefer this over the instant-call alternatives or provide exclusions.

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