register_device

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

No annotations are provided, so the description must fully disclose behavioral traits. The description only states the registration action but omits important details like permissions required, side effects, or output behavior (e.g., confirmation or errors). This is inadequate 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 structured with a clear one-line summary followed by an Args list. It is relatively concise, though the German text could be slightly tighter. No unnecessary sentences.

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 registers a device but the description lacks details on return values, error handling, or post-registration behavior. Without an output schema, the agent needs to know if it returns an ID or status. The description is incomplete for a 7-parameter, required-field 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?

With 0% schema description coverage, the description provides meaningful parameter explanations in the Args section, including examples (e.g., 'Temperatur-Sensor Halle A'). This adds value beyond the schema's property names and basic types.

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 ('Registriert ein neues IoT-Geraet im System') with a specific verb and resource. The tool name 'register_device' matches its purpose, and siblings like 'list_devices' or 'send_command' are easily distinguished.

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 does not provide explicit when-to-use or when-not-to-use guidance. While the purpose is clear, there is no mention of alternatives or prerequisites, leaving the agent to infer based on the tool name alone.

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