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

With no annotations, the description carries the full behavioral burden. It does disclose that the call is free (no cost incurred) and that the response includes payment instructions, but says nothing about whether the quoted price is locked or expires, whether calling has any side effects, or what permissions are needed.

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, scope stated first, no filler. 'The response is exactly what a buyer needs to pay' is slightly vague phrasing that could have conveyed the actual returned fields instead, but overall it is tight and front-loaded.

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 one-parameter, no-output-schema tool this is close to adequate, but the return payload is described only colloquially ('exactly what a buyer needs to pay') rather than by field, and the meaning of the sole input remains ambiguous. Those two gaps matter for an agent that must construct the call and parse the result.

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 single parameter 'task' has 0% schema description coverage, and the description does not clarify whether it expects a task ID, a task specification, or free text. It repeats the concept ('one micro-task') without adding meaning the schema lacks, so the gap is uncompensated.

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 specific verb and resource — 'Price one micro-task in USDC' — plus the secondary output (payment instructions), which clearly separates it from siblings like execute and verify. It stops short of naming the sibling relationship explicitly, but an agent can tell this is the quote step.

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?

'Free to call' and 'what a buyer needs to pay' imply this is the pre-payment quoting step ahead of execute, but the description never states when to call it versus alternatives or that it should precede execution. Usage is inferable rather than spelled out.

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