system_restart_directadmin

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It says the service will be restarted but does not explain potential downtime, whether a config check is performed first, what confirmation actually controls, or whether this is a safe operation.

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 very short, front-loaded, and contains no filler. However, the Args line mostly repeats schema information and is under-specified, so it is concise but not a model of helpful structure.

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 high-impact service restart with no annotations and almost no behavioral context, the description is incomplete. An agent cannot safely determine consequences, the confirmation contract, or when this tool should be preferred over the closely related services_restart tool.

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%, so the description must explain the confirm parameter, but it only labels it 'Required.' This is misleading because the input schema shows default false and no required parameters. It also does not state what value confirm should receive or what effect it has.

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 a specific verb and resource: 'Restart the DirectAdmin service.' This distinguishes it from related siblings like services_restart or system_update_directadmin and is not a tautology.

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 guidance about when to use this tool versus alternatives such as services_restart, csf_restart, or system_update_directadmin. The description does not mention triggers, prerequisites, or conditions that should make an agent choose this tool.

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