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

Annotations already declare readOnly, idempotent, closed-world, non-destructive, so the safety profile is covered. The description adds useful content context — that the commercial block is invariant across the three variants — but says nothing about auth requirements, failure behavior for unknown IDs, or the 'profile status' semantics.

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 short sentences, front-loaded with what is returned, followed by the disambiguating note. No filler.

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?

For a single-param read tool with no output schema and full annotation coverage, the description adequately names the returned fields and the variant relationship. The remaining gap is the undocumented robot_id format and the dangling 'layer flag' reference.

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?

Only one parameter (robot_id) and schema coverage is 0%, so the description must carry the load; it says 'one robot' but never explains the ID format or where to obtain it (e.g., software_list_robots). The mention of a 'layer flag' as the variant difference is also confusing since no such parameter exists in the schema.

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?

States a concrete verb/resource ('commercial profile of one robot') and enumerates the payload: specs, pricing, viability score, software tier, profile status. It also distinguishes itself from the hardware/mechanical get_robot variants by saying the commercial fields are identical and only the layer differs, though it references 'the layer flag' rather than naming the sibling tools.

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?

Implicitly tells the agent to pick this variant for the software layer, but never says when to prefer it over software_get_robot_software, software_get_robot_signals, or software_compare_robots. There is no explicit when-to-use or when-not phrasing, only the variant-identity note.

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