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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: no mention of what is returned, whether the lookup is by owner/name pair, or what happens for missing deployments.

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?

An elliptical two-word fragment that is short only because it is under-specified. There is no front-loaded statement of action or return, so brevity here is a defect rather than economy.

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 requiring two undocumented parameters with no output schema and no annotation-derived detail about results, the description provides nothing an agent can act on. It is effectively unusable as documentation.

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% for two required parameters (owner, name), and the description supplies no meaning for either. The example in the schema hints at an owner/name compound key, but the prose compensates for none of the coverage 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?

"Deployment detail." restates the tool name/title rather than specifying the action: it does not say whether it retrieves, renders, or summarizes a deployment, nor what a "detail" contains. No verb is present, and it is not distinguished from siblings like list_deployments or create_deployment_prediction.

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 guidance on when to use this tool versus list_deployments, deployment-prediction tools, or any other sibling. The agent is left to infer usage entirely from the name.

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