service_status_tool

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

No annotations are present, so the description carries the full burden of disclosing behavior. It only states the purpose and does not mention any behavioral traits such as whether the operation is read-only, what happens if the unit does not exist, or any required permissions. The presence of an output schema partially covers return format, but the description itself lacks transparency beyond the basic action.

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 a single, concise sentence that communicates the tool's purpose with zero wasted words. It is well-structured and front-loaded with the essential information.

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?

The tool is simple (one parameter, output schema provided). The description adequately covers the core purpose, and the output schema handles return-value details. It is complete for the task at hand, though it could benefit from slightly more context around when to use it among siblings.

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?

The input schema provides 100% coverage for the single parameter 'unit_name', including a description and example. The description does not add any additional parameter semantics beyond what the schema already states, so the baseline score of 3 is appropriate.

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 the tool's function: 'Get the status of a Podman container systemd unit.' It uses a specific verb ('Get') and resource ('status of a Podman container systemd unit'), distinguishing it from siblings like service_start, service_stop, and service_restart which perform different actions.

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?

The description implies the tool should be used to retrieve status for a specific systemd unit, which is clear from the name and description. However, it does not explicitly mention when to prefer this over alternatives like service_list (which may show statuses for all units) or service_logs. No direct exclusions or alternative guidance is provided.

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