+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already state readOnlyHint=false, idempotentHint=true, destructiveHint=false, and openWorldHint=false. The description adds nothing about behavior. In particular it omits the paid nature of the call, the required idempotency and price-cap parameters, the accepted input forms (matrix vs circuit), and the meaning of the classification output, which are important for correct invocation.
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?
It is a single short sentence, but that brevity reflects under-specification, not information density. There is no front-loaded purpose beyond the title, and no structure.
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?
The tool is complex: four parameters, nested objects, an enum payment rail, a price cap, and a provider-style paid call, with 0% schema description coverage. Despite this, the description offers only one sentence that repeats the title, leaving the agent with essentially no guidance beyond structured fields.
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 0% across four parameters including deeply nested request.matrix and request.circuit objects, so the schema alone does not explain them; the description must compensate, and it does not. It never mentions idempotency_key, max_total_price, payment_rail, or the matrix/circuit input alternatives.
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?
Tautological: description restates name/title.
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 when-to-use, when-not-to-use, or alternative-tool guidance. The description does not explain when an agent should classify an operation here rather than call the local-equivalence or target-synthesis siblings. The only usage signal is implicit in the word 'classify'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
