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

Annotations already declare readOnlyHint=true, and the description reinforces this with a GET endpoint and 'current status' context. However, it adds no depth about response format, error behavior, or other operational traits beyond this.

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?

Two compact sentences with no filler. The key action and object are front-loaded, and the endpoint line gives precise REST context without redundancy.

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?

Adequate for a simple, read-only two-parameter tool: the operation, endpoint, and schema cover most needs. It could be more complete by hinting at the returned payload shape, especially since there is no output schema, but this is a minor gap.

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 100%, so projectId and serviceId are already well documented. The description adds no additional parameter-level meaning, which is acceptable given the schema baseline.

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 verb and resource: 'Get details and current status of a single service.' This clearly differentiates from list_services, get_addon, get_job, and get_service_metrics. The REST path reinforces the exact scope.

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?

Implies usage when a single service's details/status are needed, but does not explicitly say when not to use it or mention alternatives. It does not guide the agent to list_services for discovering IDs or to get_service_metrics for metric-specific data.

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