quickCallWithEdge

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

With no annotations provided, the description carries the burden of behavioral disclosure. It does reveal meaningful behavior: immediate, one-way, outbound, and Edge TTS powered with pre-generation. It does not, however, mention side effects, auth requirements, asynchronous behavior, or what happens after invocation, which are relevant for a real outbound call tool.

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 sentences with no filler. The core action is front-loaded, and the second sentence earns its place by differentiating from quickCall. This is appropriately concise.

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 four-parameter side-effecting tool with no output schema and no annotations, the description is reasonably informative but still leaves the agent uncertain about return value, failure behavior, or whether the call is queued versus completed before the tool returns. The gap is noticeable but not fatal for a straightforward call action.

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 input schema already documents all four parameters with clear descriptions, so the tool description adds little beyond that. It reinforces the Edge TTS/voice concept, but no additional nuance is needed for correct parameter usage.

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 uses a distinct verb-resource pair: 'Place an immediate one-way outbound call voiced by Edge TTS (pre-generated).' It also differentiates from the sibling quickCall by explicitly presenting this as a 'Backup' that 'always uses Edge TTS', so an agent can recognize what it does without opening the schema.

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 names quickCall as the alternative and notes that this variant always uses Edge TTS, which implies when it might be preferred. However, it does not explicitly state when to use it versus when to avoid it, and 'Backup' is vague about whether it is a fallback or a voice-specific choice.

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