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

No annotations are provided, so the description carries the full burden. It states the tool groups and surfaces outdated devices, but does not disclose whether it is read-only, has side effects, or what 'surface' entails (e.g., returns a list, counts, or triggers actions). This is insufficient for a tool with no safety hints.

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 concise sentence that immediately states the core functionality. No wasted words; it is front-loaded and easy to parse.

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 output schema, so the description should explain return format or structure. It only vaguely mentions 'surface outdated devices' without specifying whether results are lists, counts, or other. Given the simplicity, it lacks details needed for correct invocation.

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 100% coverage with one parameter 'groupBy' fully described by its enum and default. The tool description adds no additional meaning beyond what the schema provides, so the baseline score of 3 is appropriate.

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The description clearly states the tool groups devices by firmware version and model, and surfaces outdated devices. It uses a specific verb ('Group') and resource ('devices by firmware version + model'), distinguishing it from siblings like 'list-devices' or 'list-hosts' which do not involve firmware grouping or outdated detection.

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 usage for detecting fleet inconsistency and pending upgrades, but does not provide explicit when-to-use or when-not-to-use guidance, nor alternative tools. The context is clear but lacks exclusions or prerequisites.

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