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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only repeats the tool's purpose ('get a specific response') without revealing return format, whether it returns the full response object, authentication requirements, or any side effects. This is essentially a tautology of the tool name.

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, concise sentence that is easy to read and front-loaded with the key action. However, it is under-specified, so while it is appropriately brief, it lacks the substantive details needed for a complete tool definition.

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?

With no output schema and no annotations, the description should explain what the tool returns and how the parameters relate to a 'response'. It does neither, making the tool incomplete for an agent to invoke correctly without additional external knowledge.

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 input schema has two required parameters (run_id and id) with no descriptions, and schema description coverage is 0%. The description does not compensate by explaining the relationship between run_id and id or how they are used to identify a response. Both parameters remain undefined in the description.

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 'Get a specific response' clearly states the action (get) and resource (response), and the word 'specific' distinguishes it from the sibling tool responses_list, which lists responses. However, it does not explicitly differentiate from other getter tools like runs_get or explain what a 'response' represents in this context.

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 description provides no guidance on when to use this tool versus alternatives such as responses_list or runs_get. There is no mention of prerequisites, typical use cases, or when not to use it. The only implied usage is that you need a specific response ID, but this is not stated.

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