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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds useful behavioral context by stating the response includes the referenced schemas, which matters since there is no output schema, but it says nothing about lookup-failure behavior or result size.

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?

One front-loaded sentence with no wasted words. It is efficient, though the brevity edges toward under-specification given the untouched parameters.

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 simple two-parameter lookup tool with explicit annotations, the description partially compensates for the absent output schema by naming what is returned. However, with zero parameter coverage and no error/edge-case guidance, it is only minimally adequate.

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%, so the description must carry parameter meaning — and it does not. Neither 'method' nor 'path' is mentioned, nor is the required '/v1/' prefix pattern or the GET/POST/DELETE constraint on method.

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?

Specific verb ('Return') plus a concrete resource ('one exact HotAPI operation and the schemas it references'). The word 'exact' distinguishes it from an exploratory lookup, but it never names the sibling search_docs, so differentiation is implicit rather than explicit.

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 statement of when to call this versus search_docs, no prerequisites, and no note on what happens when the method/path combination doesn't exist. The agent must infer that this is the precise-lookup counterpart to the search tool.

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