update_namespace

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

Annotations already indicate a write operation (readOnlyHint=false), so the description adds limited value. It does not disclose whether updates merge or replace, nor permissions or side effects. With annotations present, the description is adequate but not enriched.

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, uses a clear bullet format, and front-loads the purpose. Every sentence is informative 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?

Given the tool has 5 parameters and no output schema, the description covers the purpose of each parameter. However, it does not explain the update behavior (merge vs replace) or what happens if only some optional parameters are provided. Slight gap but overall sufficient.

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%, but the description adds meaning for each optional parameter (e.g., 'cpu_limit: New CPU limit in MHz', 'memory_limit_mib: New memory limit in MiB'). It clarifies units and purpose beyond schema titles.

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 '[WRITE] Update vSphere Namespace resource quotas or storage policy' with explicit verb and resource. It lists parameters and differentiates from siblings like create_namespace and 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?

The description implies usage for updating an existing namespace (e.g., 'Update vSphere Namespace'), but does not explicitly state when to use versus alternatives or exclude scenarios. No mention of prerequisites or dependencies.

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