get_device_info

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

No annotations are present, so the description carries the full burden. It discloses the underlying HTTP GET endpoint and method, and enumerates the complete StatusDevice return object with field types and meanings. This goes beyond a surface-level summary, though it omits potential error states or permission requirements.

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 structured with a clear lead sentence, a compact API reference line, a bulleted list of return fields, and a brief use-case note. No filler or repetition; each sentence adds information.

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 no output schema, the description precisely enumerates all returned fields and their meanings, and adds use cases. The behavior is fully explained for a no-argument getter, and it distinguishes itself from its many siblings.

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 tool takes zero parameters, so the description need not explain inputs. Baseline 4 applies; the empty input schema is fully consistent.

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 opens with 'Retrieve detailed hardware and identification info about the Busy Bar device,' a specific verb and resource. The detailed field list distinguishes it from sibling get_* tools like get_device_name and get_device_status.

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?

An explicit 'Use case' section lists inventory tracking, device identification, and troubleshooting. This gives clear context, though it does not name alternative tools or when not to use this one.

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