get_product_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 reveals that broadcasts return no responsescars, which is a key behavioral trait, and describes the hardware version byte order. However, it does not clarify whether the tool is read-only (does not modify device state) beyond the 'Get' command, does it discuss error cases, timeouts, or what happens if the motor is not found. The description is incomplete in disclosing the operational behavior of a read-only command.

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 dense but well-organized: it starts with the tool's purpose, then lists return fields in a bullet-like format, and finally explains the 'motor' parameter with examples. It is appropriately detailed for the complexity, and the front-loading of the firmware command context is useful. Slightly verbose but each element serves a purpose.

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 returns structured product information (including firmware compatibility) and has one parameter. The description covers the return fields and the parameter's syntax, which is largely sufficient given the simplicity. However, it lacks notes on error handling, typical use cases (e.g., pre-upgrade checks), and does not clarify whether the command is read-only, which is relevant for a 'Get' operation. Since the output schema is absent, the description does need to convey return semantics, which it does 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?

Schema description coverage is 0%, and the only parameter 'motor' is a string with no schema description. The description provides substantial semantics for 'motor': it can be an alias (e.g., 88), a 16-hex-digit unique ID, or 'all' to broadcast. This is highly valuable and compensates for the schema's lack of detail. However, since it is the only parameter, the baseline for 0 params is 4, but here there is exactly one param, and the description does fully compensate, so a score of 5 is not appropriate; a 1 seems too low. Wait: the description directly explains the parameter's allowed values, which is beyond what the schema provides, so I'll score this as 4, not 1. (Correction in justification.)

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's purpose: retrieving product information via a firmware command, and lists the specific fields returned (product code, firmware compatibility, hardware version, serial number, unique ID, reserved). It distinguishes itself from siblings like get_product_specs and get_product_description by providing a distinct, comprehensive set of product metadata. However, it does not explicitly differentiate from get_firmware_version, though the field list makes it clear.

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 implicitly conveys that this is for retrieving product details, and mentions the 'motor' parameter accepts an alias, a unique ID, or 'all' to broadcast (with the note that broadcasts get no responses). However, it does not explicitly state when to use this tool over alternatives like get_product_specs or get_firmware_version, nor does it provide conditions for when not to use it. The firmware compatibility note hints at use during upgrades but lacks explicit routing.

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