get_tkc_cluster

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the '[READ]' prefix adds no value. The description does not elaborate on what 'detailed info' includes, required permissions, or any behavioral traits beyond the annotations.

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 extremely concise with a front-loaded purpose line and a clean 'Args:' block. Every sentence is necessary; no filler or 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?

No output schema exists, and the description does not describe the return value beyond 'detailed info', which is vague. An agent cannot know if the response includes configuration, status, or other fields. No error cases or relation to siblings mentioned.

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?

With 0% schema description coverage, the description explains each parameter: 'TKC cluster name', 'vSphere Namespace containing the cluster', and 'vCenter target name'. This adds meaning, though it does not indicate that 'target' is optional (default null) from the schema.

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 'Get detailed info for a single TKC cluster', with a verb 'Get', specific resource 'TKC cluster', and the qualifier 'single' differentiating it from sibling tool list_tkc_clusters. The '[READ]' prefix further clarifies the non-modifying nature.

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 implies use for single cluster details, contrasting with list_tkc_clusters, but no explicit guidance on when to use this tool versus alternatives, when not to use, or prerequisites. The agent must infer usage from context.

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