Behavior4/5

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

As a listing tool with no annotations, the description sufficiently conveys that it is a safe, read-only operation. No side effects or authorization needs are mentioned, but the behavior is straightforward.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that is concise and informative, with no wasted words. It effectively front-loads the action and output.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with no parameters and no output schema, the description provides sufficient context. It could be slightly enhanced by noting it returns a list, but it is already adequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters, and schema coverage is 100% (empty). According to guidelines, 0 parameters yields a baseline of 4, and the description adds no param info unnecessarily.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists all Amazon Echo devices with specific attributes (serial numbers, types, online status), using a specific verb and resource that distinguishes it from sibling tools like alexa_list_smarthome_devices and alexa_list_groups.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when a list of Echo devices is needed, but does not explicitly state when to use this tool versus alternatives like alexa_list_smarthome_devices for other device types.

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