get_device_info

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 correctly implies a read-only operation but does not explicitly state non-destructiveness, latency, or authentication requirements. For a simple parameterless read, this is adequate but minimal.

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 with no wasted words. It front-loads the purpose and lists key fields efficiently.

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 tool has no parameters, no output schema, and is straightforward, the description is largely complete. It specifies what data is returned. However, it lacks mention of prerequisites (e.g., machine must be connected) or possible failure modes. Still, it serves its purpose well.

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, and schema description coverage is 100%. There is no need for parameter-level detail in the description, and it adds nothing beyond the schema. Perfect score for a parameterless tool.

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 retrieves information about the connected Meticulous espresso machine, listing specific fields (model, firmware version, serial number, build info). The verb 'Get' and resource 'device info' are unambiguous, and it distinguishes itself from sibling tools like get_status or get_settings.

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 use when device information is needed but provides no explicit guidance on when not to use it or alternatives. For example, it does not mention that get_status might be more appropriate for operational status. Lacks exclusion criteria or comparative context.

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