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

No annotations are provided, so the description carries the full burden. It does not disclose whether ranking has side effects, how the spend cap is enforced, what happens when the cap is exceeded, or any rate/ordering behavior. The behavioral profile is largely unknown.

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 a single, well-structured sentence with no filler. It front-loads the core purpose, though its brevity leaves key behavioral and parameter details uncovered.

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 tool with 4 parameters, nested objects, no output schema, and no annotations, this description is too sparse. It lacks return-value expectations, parameter semantics for k and features, and any note on how ranking output is structured.

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?

With 0% schema description coverage and 4 parameters, the description only implicitly maps to tenant_id and candidates, while k and features are completely unaddressed. It does not compensate for the schema gap.

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 clear action — 'Rank candidate items' — with a specific resource ('a tenant') and a constraint ('monthly spend cap'). It is distinguishable from sibling tools like record_feedback and budget_status, though it does not explicitly name them.

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 phrase 'for a tenant under the monthly spend cap' implies the context in which this tool is appropriate, but there is no explicit when-to-use or when-not-to-use guidance, and no alternative tools are named.

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