service_status

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It clearly indicates a read-only operation via Get and enumerates the returned data: active state, uptime, and memory. It does not mention error behavior or prerequisites, but for a simple status query this is a minor gap.

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 compact and well-structured: a single front-loaded summary sentence followed by a focused parameter explanation. There is no redundant or fluffy content.

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 one-parameter tool with an enum constraint and no output schema, the description is nearly complete: it states the input options, the output fields, and the scope. It could mention the response format or failure behavior, but those are minor for this level of complexity.

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 compensate. The Args section defines name as the service to query and lists the four valid values, which adds real semantic meaning beyond the bare enum. It does not explain what each service is, but that is not necessary 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 opens with a specific verb and resource: Get detailed systemd status for one known homelab service, including active state, uptime, and memory. This clearly states what the tool does. It does not explicitly distinguish itself from sibling tools, but the resource scope is specific enough to make the purpose clear.

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 on when to use this tool versus its siblings like disk_usage, game_server_status, or system_summary. The phrase one known homelab service adds scope but does not explain selection criteria, exclusions, or alternative tools.

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