restart_prestissimo_engine

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

With no annotations provided, the description carries full burden for behavioral disclosure. It simply says 'Restart' without explaining side effects (e.g., downtime, state transitions), required permissions, or response details. This is minimal for a mutation tool.

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, with three concise sections: purpose, args, returns. It is front-loaded with the key action. However, the brevity limits content; it earns a 4 for efficiency but not a 5 due to lack of depth.

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?

Given the tool's complexity (a restart operation requiring state awareness) and absence of output schema details beyond field names, the description is incomplete. It lacks prerequisites, error information, and behavioral context, leaving gaps for the agent.

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 has 0% description coverage, and the description only adds 'Engine identifier' for engine_id. This clarifies the parameter's role but provides no format, constraints, or context. The addition is minimal, not compensating fully for the schema gap.

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 action 'Restart' and the resource 'Prestissimo engine' in watsonx.data, distinguishing it from sibling 'restart_presto_engine' by engine type. It uses a specific verb and resource, making the tool's purpose 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 like restart_presto_engine, pause/resume, or scale. It does not specify prerequisites (e.g., engine state) or exclude any scenarios, leaving the agent to infer usage from context.

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