get_namespace

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint false. The description adds valuable behavioral context beyond those hints: it returns a raw vCenter object rather than a list envelope, and warns that a CONFIGURING namespace may not yet have quotas applied. This helps the agent interpret results correctly.

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 dense but well-organized: a clear opening statement, the return shape, routing guidance to related tools, and a caveat. Each sentence earns its place and no filler is present.

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?

Even though there is no output schema, the description names the key returned fields (config_status, description, storage_specs, quotas) and explains how to discover the required name parameter. It also points to the correct sibling tools for follow-up queries, making it sufficiently complete for an agent to invoke this tool correctly.

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 the schema already documents both parameters well. The description reinforces that 'name' comes from list_namespaces, matching the schema's example, but does not add additional parameter-level meaning beyond what the schema provides.

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 states a specific verb and resource: 'Get detailed configuration for a single vSphere Namespace.' It also distinguishes itself from sibling tools by explicitly saying it returns 'one raw vCenter namespace object, not the list envelope,' which differentiates it from list_namespaces and related listing tools.

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 explicit usage sequencing: use list_namespaces first to discover the name, then call this tool; follow with list_namespace_storage_usage for PVC usage or list_tkc_clusters for clusters inside. It also provides a point-in-time caveat that helps the agent know when the result may be incomplete.

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