set_device_name

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

With no annotations provided, the description carries full burden but only states it changes the AutoBot display name. It lacks details on permissions needed, whether the change is reversible, side effects, or error conditions beyond the generic return message mention. 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 efficiently structured with a clear main statement, a clarifying note, and separate sections for args and returns. Every sentence adds value without redundancy, making it easy to parse and understand 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?

For a simple mutation tool with one parameter and an output schema, the description covers the basic purpose and parameter meaning. However, without annotations and lacking details on behavioral aspects like permissions or side effects, it's only minimally adequate, leaving gaps in operational understanding.

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 description adds meaningful context for the single parameter 'name' by specifying it's a 'Display name for the device', which clarifies its purpose beyond the schema's basic type. With 0% schema description coverage, this compensates well, though it doesn't detail constraints like length or format.

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 specific action ('Set a display name') and the resource ('for the device'), distinguishing it from sibling tools like 'get_device_name' by specifying it's a write operation. The note further clarifies the scope by differentiating between system device name and AutoBot display name.

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?

No explicit guidance is provided on when to use this tool versus alternatives. While it distinguishes from 'get_device_name' by being a setter, it doesn't mention prerequisites, permissions, or contextual scenarios for usage, leaving the agent without operational context.

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