get_deployments

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

With no annotations provided, the description carries the full behavioral disclosure burden. It does convey the scope ('across namespaces') and the output content, which implies a read-only list operation, but it does not mention default behavior when namespace is omitted, potential cluster-wide cost, or any errors that might occur.

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, front-loaded sentence that efficiently covers purpose, scope, and key returned fields. Every phrase contributes meaningful selection and invocation information 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?

For a low-complexity tool with one optional parameter and no output schema, this description is nearly complete: it names the resource, the filtering capability, and the main output fields. The main missing piece is explicit guidance on how this differs from the similarly scoped sibling tool get_deployment_status.

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 single parameter is already well documented in the schema with 100% coverage. The description adds useful meaning by clarifying that the tool operates 'across namespaces' and shows status details, which helps an agent interpret the optional namespace filter as a scope restriction rather than a required selector.

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 clearly states the verb ('Get status') and resource ('Kubernetes deployments'), and specifies the type of returned data: replica counts, images, and health status. It is distinct enough from the broader sibling list, though it does not explicitly differentiate itself from the similarly named 'get_deployment_status'.

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 gives no guidance on when to prefer this tool over siblings such as get_deployment_status, get_kubernetes_status, or get_service_health. It implies a broad read across namespaces but provides no exclusions or selection criteria.

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