service_stop_tool

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

With no annotations provided, the description carries the full burden, but it only states 'Stop' without disclosing whether the operation is synchronous, requires elevated privileges, or how it affects the running container. The mutating nature is implied but no additional behavioral context is given.

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 sentence, free of filler or redundancy. It is appropriately concise for a tool with one parameter and a straightforward action.

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's simplicity, complete schema, and presence of an output schema keep the description minimally viable. However, the lack of usage guidance and behavioral transparency means an agent might not fully understand how this tool differs from container_stop_tool or whether additional side effects exist.

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 schema description coverage is 100% and the parameter unit_name is clearly documented with an example. The description adds no extra parameter semantics, so the baseline 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 uses a specific verb 'Stop' with a specific resource 'Podman container systemd unit', which clearly distinguishes it from container-level tools like container_stop_tool. The phrase 'systemd unit' makes the operational target unambiguous.

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 provides no guidance on when to use this tool versus alternatives such as container_stop_tool, service_start_tool, or service_restart_tool. It does not state prerequisites (e.g., the unit must be managed by systemd) or exclude use cases, leaving the selection entirely to the agent.

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