list_vlans

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

With no annotations provided, the description must fully disclose behavioral traits, but it only mentions extracting and listing VLANs without stating that it is a read-only operation, authentication requirements, or potential performance implications. The example hostname is helpful but insufficient for 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 extremely concise: one sentence for purpose followed by a brief parameter explanation. No superfluous words, and the most important information (what the tool does) is front-loaded.

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 that an output schema exists (but not shown), the description does not need to detail return values. However, it leaves ambiguity about 'network names' and does not clarify whether the hostname alone is sufficient or if additional context is needed. The completeness is adequate but not thorough for a tool with many siblings.

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?

Although the schema has 0% coverage (no descriptions in properties), the tool description includes an 'Args' section that explains the hostname parameter with an example ('vCenter.domain.local'), adding useful meaning beyond the schema. This compensates well for the missing schema descriptions.

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 action ('Extract and list') and the resource ('VLAN information from network names'). It distinguishes from siblings like 'get_vlan_info' by implying a listing operation, though it does not explicitly say 'all' or 'multiple', which slightly limits clarity.

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 such as 'get_vlan_info' or 'list_networks'. The description lacks context about prerequisites or filtering, leaving the agent without clear decision criteria.

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