devices_list_chromeos

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

No annotations are present, and the description discloses no behavioral traits. It does not mention whether this is a read-only operation, whether results are paginated, or any side effects. The burden falls entirely on the description, and it fails to provide any added behavioral context.

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 concise with no wasted words, but it is under-specified. It is structurally fine as a single sentence, but the lack of detail makes it borderline between appropriate brevity and inadequate explanation.

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 is simple, but the description is missing essential context. There is no output schema, no annotations, and the parameters are unexplained. This is incomplete for a list tool that has a query parameter and result limits.

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 schema has two parameters (query, maxResults) with 0% coverage in the description. The description does not explain what 'query' does or how 'maxResults' behaves. Since schema coverage is low, the description needed to compensate but did not.

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 uses a specific verb 'List' and identifies the resource as 'managed ChromeOS devices', which is clear and distinguishes it from sibling tools like devices_list_mobile. There is no ambiguity about what this tool does.

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 guidance is provided on when to use this tool vs alternatives. The description simply states what it does without mentioning any conditions, prerequisites, or comparisons to sibling tools such as devices_list_mobile.

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