update_namespace

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

Annotations indicate readOnlyHint=false, and the description starts with '[WRITE]' aligning with that. It adds that the tool updates resource quotas or storage policy, but does not disclose overwriting behavior, what happens when parameters are omitted, or required permissions. With annotations present, the bar is lower, but more detail would improve transparency.

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 concise, front-loading the purpose with '[WRITE]' and a clear statement, followed by a structured argument list. It is efficient but could improve formatting of the list.

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?

Given 5 parameters, no output schema, and no parameter descriptions in the schema, the description is incomplete. It misses the target parameter and does not explain return values, idempotency, or behavior on omitted optional parameters.

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%, so the description must compensate. It describes four parameters (name, cpu_limit, memory_limit_mib, storage_policy) with units and optionality, adding meaning beyond the schema. However, it omits the 'target' parameter entirely, leaving a significant 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?

The description clearly states 'Update vSphere Namespace resource quotas or storage policy', specifying the verb and resource. However, it fails to mention the 'target' parameter present in the schema, and does not distinguish from sibling tools like create_namespace or delete_namespace.

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?

No guidance is provided on when to use this tool versus alternatives, nor any prerequisites or conditions. The description does not contrast with create_namespace or other namespace-related tools.

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