get_device

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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It usefully reveals that macmon NAC info is automatically included if configured, and hints at the return format. However, it omits crucial behavioral traits such as whether the tool is read-only, potential error states (e.g., device not found), or authentication requirements, leaving gaps in transparency.

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 well-structured with Args and Returns sections, and the information is relevant and concise. It includes necessary details without extraneous text. The only slight inefficiency is the repetition of the hostname example, but overall it is appropriately sized and front-loaded.

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?

Given the absence of an output schema, the description thoroughly explains what the tool returns (hardware, OS, last user, group, agent status, macmon NAC status). It covers the primary use case and the automatic macmon inclusion. However, it does not address error scenarios or permissions, leaving minor gaps for a tool with a single parameter and no output schema.

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 provides only a type and title for device_id with no description (0% coverage). The description compensates well by explaining it accepts either a GUID (from list_devices) or a hostname, which adds significant meaning beyond the schema. A higher score would require more detail on format constraints or validation.

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 it retrieves all details of a single device, specifying it accepts both GUID and hostname. It distinguishes from siblings like list_devices (which returns multiple devices) and get_device_update_status (which focuses on update status), making the tool's purpose unambiguous.

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 provides clear context on when to use this tool (to get full details of one device) and mentions it accepts both GUID and hostname. However, it does not explicitly exclude or compare to alternatives like search_devices, which could also return a single device. Thus, guidance is strong but not exhaustive.

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