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

Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds genuinely useful traits beyond that: deterministic, evidence-bounded, and signed, plus a fixed cost. It does not explain what 'signed' implies for the output, but the annotation coverage is strong enough that this is not a major gap.

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 purpose, but the structure is fragmented: a stray semicolon and an abrupt price fragment ('; 0.004 USDC.') disrupt readability. No words are wasted, but the formatting is clumsier than it should be.

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 output schema exists, so return-value documentation is not required, and the annotations cover the safety profile. Still, the open input schema and lack of exact request-body guidance leave an invocation gap, and there is no usage guidance to help the agent choose this tool over related siblings.

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?

There are zero named parameters, so the schema itself provides little to work with. The description adds conceptual meaning by naming the inputs: 'verified demand and verified provider supply.' However, the input schema's minProperties: 1 with additionalProperties: true still leaves some ambiguity about the exact expected object shape.

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 opens with a concrete action and resource: 'Detect capability shortages' and specifies the method ('using verified demand and verified provider supply'). This makes the core purpose clear, though it does not explicitly distinguish itself from siblings such as capability_verification or market_demand_predictor.

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?

No when-to-use guidance, prerequisites, or alternatives are provided. With a large sibling set of demand, supply, verification, and prediction tools, the agent is left to infer when this detector should be selected instead of being told.

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