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

With no annotations provided, the description must carry the full behavioral burden. It states that aliases are display-only, which is helpful, but it does not disclose whether the operation overwrites existing names, requires permissions, has side effects, or what the response looks like. This is insufficient 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 two sentences long, front-loads the core action, and has zero redundancy. Every word adds value, making it exceptionally concise and well-structured.

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 has no annotations, no output schema, and only 0% parameter coverage. The description explains the core purpose but fails to cover necessary context like success behavior, effects on existing data, error conditions, or relation to other tools. This makes it incomplete for an agent to invoke confidently.

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?

Schema coverage is 0%, so the description must compensate. It implies that 'name' is the display alias and 'id' identifies the device, but it does not explain any constraints, formats, or uniqueness. This partially adds meaning beyond the raw schema but not fully.

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 (assign), the resource (device), and the specific concept (display alias). It also distinguishes itself by clarifying that aliases are for display only and not for ID resolution, which differentiates it from naming that affects identity.

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 implies when to use this tool (when you need a display-only label) but does not explicitly mention alternatives or exclusions. For example, it doesn't reference sibling tools like set_device or remove_name, nor does it say when to avoid this tool (e.g., for ID resolution).

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