list_devices

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

Even though annotations are absent, the description explicitly discloses that passwords, secrets, and sudo passwords are excluded from results. This is a valuable behavioral caveat for a list operation and goes beyond what the name alone suggests.

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 with the key privacy caveat parenthesized. There is no filler, redundancy, or unnecessary detail.

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 zero-parameter, no-output-schema tool, the description adequately captures what the tool does and an important constraint on its results. It could additionally state that it is read-only or describe the result format, but these are non-critical for selecting and invoking the 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?

The input schema has zero parameters, so parameter documentation is not applicable. The baseline of 4 is appropriate because there is nothing for the description to clarify.

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 a specific verb ('enumerate') and resource ('target devices in the inventory'). It is semantically distinct from the sibling run_command, but it does not explicitly name or differentiate from that sibling.

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 when-to-use or when-not-to-use guidance is provided. The sibling run_command is not mentioned, so the agent must infer the appropriate choice from tool names and intent rather than from explicit guidance.

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