speaking_time

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

With no annotations, the description carries the full burden of behavioral disclosure. It does reveal the monetary cost ($0.001 USDC via x402), which is a behavioral trait, but it omits what the tool computes, side effects, or return format. This is minimal transparency at best.

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 but under-specified. The single sentence contains only category and cost, which is not 'conciseness' but 'scarcity'. It does not front-load any functional information, so it fails to earn 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?

Given the tool's name suggests a measurable concept (speaking time), the absence of an output schema, real annotations, or any explanation of inputs/outputs makes this completely inadequate. The description does not help the agent understand what the tool does or when to use it.

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 defines a single generic 'params' object with no specific properties, and the schema_description_coverage is misleadingly 100% because it only describes the generic wrapper. The description adds no meaning about what parameters should be passed, leaving the agent completely without guidance.

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 only states the tool name and category ('Other Utilities tool') plus cost, but does not specify any verb or resource. It fails to state what 'speaking time' actually does, making it nearly a tautology. It also does not distinguish itself from siblings like 'reading_time'.

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?

There is no indication of when to use this tool vs alternatives. No context, prerequisites, or exclusions are provided. The only extra info is cost, which is not a usage guideline.

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