rename_device

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

No annotations exist, and the description only implies a mutation operation without disclosing side effects, required permissions, error handling (e.g., invalid IDX/name), or any behavioral nuances beyond the rename itself.

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, compact sentence that conveys the essential purpose without extraneous words, making it easy to parse quickly.

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 description covers the core functionality but omits information about expected behavior when parameters are combined or omitted, and does not mention the return value (despite an output schema existing). It is adequate but not fully comprehensive for a tool with multiple optional parameters.

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 coverage, the description must compensate. It adds meaning by explaining that 'idx' and 'old_name' are alternative identifiers for the device. However, it does not clarify whether exactly one is required or what happens if both are provided, leaving ambiguity.

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 explicitly states the action (rename) and the resource (device), and uniquely identifies two methods of selecting the device (by IDX or old name), clearly distinguishing this from other device-related tools.

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 a specific identification method or when to avoid using this tool. There is no mention of prerequisites, alternatives, or context for proper usage.

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