Suspend VM

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

Annotations declare destructiveHint: false, but the description does not explain what 'suspend' entails (e.g., saves state, stops execution, retains memory). With no behavioral details beyond the one-line description, the agent lacks understanding of side effects, reversibility, or required permissions.

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 short (one sentence) but fails to include necessary detail. While concise, it sacrifices essential information, making it less helpful. The length is appropriate only if the tool is trivial, but the existence of multiple siblings and parameters suggests more detail is warranted.

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's complexity (two parameters, one with enum) and the presence of closely related siblings (pause_vm, stop_vm), the description is incomplete. It does not clarify return values, error conditions, or the difference between suspend and pause. No output schema exists, so the description should have covered these gaps.

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 coverage is 50% (only vmxPath has a description). The description adds no additional meaning to parameters; it does not explain the 'mode' enum values or their implications. The agent must infer from the schema alone, which is insufficient for correct invocation.

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 'Suspend a VMware VM' clearly states the action (suspend) and resource (VMware VM). However, it does not distinguish this from the sibling 'pause_vm', which may have similar behavior. The verb and resource are specific and actionable.

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 on when to use this tool versus alternatives like 'pause_vm', 'stop_vm', or when to select the 'soft' vs 'hard' mode parameter. The description lacks any context on prerequisites, typical use cases, or comparisons to sibling tools.

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