Reboot Vultr instance

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

Annotations provide write behavior (readOnlyHint=false) and non-destructive hint. The description adds queuing semantics and the requirement for exact confirmation, which is valuable beyond annotations. However, it does not disclose whether multiple calls are safe or what happens to running operations.

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?

A single sentence is highly concise but lacks important details such as asynchronous behavior or state requirements. It is front-loaded with the core action, making it efficient for quick reading.

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 simplicity (2 params, no output schema), the description covers the core purpose and the confirmation requirement. However, it omits operational details like asynchronicity and instance existence prerequisites, leaving moderate 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% with only confirm parameter described. The description adds no new semantic information about parameters beyond what the schema provides. For an agent, this offers little added value.

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 uses specific verb 'Queue...reboot' and resource 'Vultr instance', clearly distinguishing from sibling tools like delete_instance or create_snapshot. It also includes the condition 'after exact confirmation', which clarifies the required input.

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 explicit guidance on when or when not to use this tool. It does not mention alternatives or prerequisites, leaving the agent to infer context from the tool name alone.

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