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

Annotations already declare the full safety profile (readOnly, idempotent, non-destructive, closed-world), so the description doesn't need to. It adds useful contract detail about what the payload contains and that BOM existence is a yes/no indicator rather than a full BOM. It omits error behavior for an invalid robot_id and gives no sense of payload size.

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?

Two tight sentences, content front-loaded, no filler. The only weak spot is the trailing 'layer flag' clause, which introduces ambiguity rather than value.

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?

With no output schema, the description carries the burden of explaining return content, which it does at a high level (specs, pricing, viability score, BOM-existence flag). Still missing are the identifier's provenance and failure behavior, both relevant for a single-required-param lookup tool.

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% for the single parameter robot_id, so the description must compensate and it does not — robot_id is never mentioned, nor its format or how to obtain one (e.g., from hardware_list_robots). This is a meaningful gap for a tool whose only input is an identifier.

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?

Names a specific resource (one robot's commercial profile) and enumerates its contents: specs, pricing, viability score, plus semiconductor BOM existence. It also positions itself against the other two get_robot variants. The closing phrase 'the layer flag is the only difference' is slightly muddy since no layer parameter exists in the schema, but the intent is still readable.

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?

Implies the tool is the hardware-layer counterpart of mechanical_get_robot/software_get_robot and that the commercial payload is identical across them, which is useful routing context. However, it never states when to prefer this over hardware_get_robot_hardware, get_robot_capabilities, or get_robot_support, nor any exclusion conditions.

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