Reboot Cloud Server

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

Annotations already declare readOnlyHint=false and openWorldHint=true, so the '[WRITE]' tag is redundant. The description adds the API version and endpoint path but says nothing about disruption/downtime, whether the reboot is graceful or forced, or whether it requires the server to be in a particular state - all important for an operationally risky mutation.

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 front-loaded line with the write tag and endpoint first. There is no wasted prose, though it is terse to the point of under-specification rather than genuinely economical.

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?

For a mutation tool with no output schema, only partial schema coverage, and no rich annotations, the description leaves critical operational details (downtime, required server state, prerequisites) unstated. An agent could call it, but not confidently.

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 only 50%: 'region' is documented in the schema while 'server_id' has no description. The description's path template hints that both are path parameters, but adds no format, validity, or lookup guidance, so it fails to compensate for the uncovered parameter.

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 name and title state a specific verb (reboot) and resource (Cloud Server), and the description reinforces this with the exact REST endpoint POST /regions/{region}/servers/{id}/reboot. It is unambiguous what the tool does, but it never differentiates from close siblings like power_on_server, power_off_server, or create_server.

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?

There is no when-to-use guidance and no mention of alternatives such as power_off_server + power_on_server or how a reboot differs from a hard power cycle. The agent must infer context purely from the tool name.

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