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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds genuinely useful behavior context by noting the ssh command is only present once the pod is RUNNING, but it says nothing about authorization (must you own the pod?) or the not-found case.

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?

A single front-loaded sentence fragment with zero filler; every element (status, ssh, price, spend) earns its place. It is slightly telegraphic, reading as a noun phrase rather than a statement of what the tool does.

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 one fully documented parameter, no output schema, and annotations covering safety, the description is nearly sufficient: it previews the payload and flags the conditional ssh field. Only error/auth behavior for a missing or foreign pod is absent.

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 coverage is 100% and the pod_id description already tells the agent to use an id as shown by list_pods. The tool description adds no further meaning about the identifier, so the baseline 3 is correct.

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 specific resource ('one pod') and enumerates the returned fields (status, ssh command, price per hour, spend), which clearly distinguishes it from the sibling list_pods that returns many pods. The verb is only implied by the title rather than the description itself.

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?

'One pod' implicitly contrasts with list_pods, so an agent can infer this is the single-pod lookup, but there is no explicit when-to-use guidance, no alternative named, and no note on what happens for an unknown pod_id.

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